Embodiments of the disclosure are generally directed to coated lift plungers, which have improved hardness, durability, and corrosion resistance, as well as methods of making, reworking, and using the same.
Lift plungers are used in artificial lift and plunger lift systems in petroleum wells (e.g., a well containing liquid, gaseous, or solid hydrocarbons or combinations thereof) in order to increase production or remove contaminants. A lift plunger is exposed to corrosive conditions, extreme impact, and high wear mechanisms or processes. Currently, coated steel or titanium is used. However, it is difficult to customize the performance of such materials, and, in the case of titanium, costly to machine. Accordingly, there is a need for customizable lift plungers with improved corrosion resistance, hardness, and durability. The present disclosure addresses these issues and provides related improvements with significant advantages.
Aspects of the present disclosure include a method for preparing a coated lift plunger, the method comprising: applying a laminate coating on a surface of a plunger core that is substantially symmetrical about a longitudinal axis and has a first diameter and a plunger body, thereby forming the coated lift plunger. Additional aspects of the present disclosure include a coated lift plunger produced by the methods described herein.
Further aspects of the disclosure include a coated lift plunger comprising: a plunger core that is substantially symmetrical about a longitudinal axis and has a first diameter and a plunger body; and a laminate coating on a surface of the plunger core, the laminate coating having a thickness, the laminate coating comprising a first and a second layer, the first layer having a first composition and a first nanostructure, and the second layer having a second composition and a second nanostructure.
Aspects of the present disclosure further include a method for reworking a lift plunger having mechanical wear, the method comprising: determining, based on a measured dimensional characteristic of the lift plunger, an amount of mechanical wear; identifying a wear surface based on a comparison of the measured dimensional characteristic and an original dimensional characteristic of the lift plunger before use or wear; determining an electroplating rework process to deposit a laminate coating onto the wear surface; and executing the electroplating rework process.
In additional aspects, the present disclosure provides a method for clearing downhole accumulations from a well comprising: positioning a coated lift plunger in a petroleum well tube; and releasing the coated lift plunger into the petroleum well tube, thereby allowing the coated lift plunger to travel in the petroleum well tube carrying liquids and downhole accumulations from a bottom position of a petroleum well to a top position of the petroleum well, and allowing a downhole gas to travel from the bottom position of the petroleum well to the top position of the petroleum well.
The detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number appears. The same right-most digits of a reference number in different figures indicate similar or identical components or features.
The sizes and relative positions of elements in the figures are not necessarily drawn to scale. For example, the shapes of various elements and angles are not drawn to scale and some of these elements are arbitrarily enlarged and positioned to improve figure legibility. Further, the particular shapes of the elements as drawn, are not intended to convey any information regarding the actual shape of the particular elements, and have been solely selected for ease of recognition in the figures.
The present disclosure is generally directed to coated lift plungers, which have improved hardness, durability, and corrosion resistance, as well as methods of making, reworking, and using the same.
Prior to setting forth this disclosure in more detail, it may be helpful to an understanding thereof to provide definitions of certain terms to be used herein. Additional definitions are set forth throughout this disclosure.
“Electrodeposition” or “electrodeposited” refers to a process or the resultant product, respectively, in which electrolysis is used to deposit a coating onto a workpiece. In other words, the workpiece is contacted with (e.g., partially immersed in, or fully immersed in) an electrolyte solution containing one or more ions (e.g., metal, ceramic, etc.) while an electric current is passed through the workpiece and the electrolyte solution, resulting in a thin coating being deposited on the surface of the workpiece. Such an electrodeposited coating that includes two or more layers may be referred to as a “laminate” coating.
For the purposes of this disclosure “coatings” include any thin layers that are electrodeposited onto the surface of a workpiece. Therefore “coatings,” as used herein, includes claddings, which are made of a series of thin electrodeposited layers on the surface of a mandrel, where the mandrel is removed after the formation of the electrodeposited layers. Claddings are generally fastened to another article as a protective layer after formation.
A “nanolaminate coating” refers to an electrodeposited coating that includes two or more layers in which the individual layers have a thickness of less than 10,000 nanometers (i.e., 10 microns). Although the processes described herein are particularly suited for providing nanolaminate coatings, the same or similar processes can also be used to make similar articles in which the individual layers that are thicker than 10 microns. Such coatings may be referred to as “microlaminate coatings.”
The term “plunger core workpiece” (abbreviated as “plunger core”) includes any item with a surface onto which a coating is electrodeposited. Plunger cores include substrates, which are objects on which a coating is applied, and mandrels, which are substrates from which the coating is removed after formation.
“Additive manufacturing” refers to the preparation of three-dimensional articles by the sequential addition of materials. The process includes all forms of direct digital manufacturing, including, direct digital deposition, three-dimensional printing (3D-printing), selective laser sintering (SLS), sintering laser melting (SLM), fused deposition modeling (FDM), stereolithography (SLA), continuous liquid interface printing (CLIP), cutting woven fabric, forming woven fabric, cutting non-woven fabric, forming non-woven fabric, cutting foam sheets, or forming of foam sheets.
“Direct digital manufacturing” or “rapid prototyping” refers to the additive manufacturing of a three-dimensional solid article of any shape from a digital model. The process is an additive one, wherein successive layers, ribbons, beads, or areas of material are laid down or solidified in different shapes to form a three-dimensional article.
“Selective laser sintering” (SLS) refers to a process wherein a bed of powder is locally bonded by the action of a laser to form one cross section of an article at a time.
“Fused Deposition Modeling” (FDM) refers to a process wherein molten material (e.g., thermoplastic) is used to sequentially build up an article of a desired shape.
“Stereolithography” (SLA) refers to a process wherein a liquid polymer is locally solidified by photo-initiated crosslinking. In the process, light is focused onto the surface of a container of uncured photopolymer, and the desired 2D cross-sectional shape is ‘drawn,’ producing a solidified 2D pattern. Repeating this process produces 3D geometries of the desired shape.
“Laminated Object Manufacturing” (LOM) means the use of thin layers cut to shape and joined together (e.g., paper, polymer, metal) to form a desired three-dimensional article.
“Polymeric materials” refers to any material comprising a polymer (i.e., a macromolecule composed of repeated subunits) that is sufficiently malleable, but also sufficiently rigid, so as to form a solid article. Polymeric materials may be natural, semi-synthetic, or synthetic. Polymeric materials include plastics.
“Plastic” refers to a subset of moldable polymeric materials comprising synthetic or semi-synthetic organic compounds. Plastic can be molded into solid objects using a variety of methods. Examples of plastics include arylamides, acrylamides, polybenzimidazole (PBI), polyetherimide, polyetherketoneketone (PEKK), polyether ether ketone (PEEK), polyamide, polyimide, polyamide-imides, polyphenylene oxide (PPO), polystyrene (PS), PPO and PS, polyphthalamide (PPA), polyvinyl alcohol (PVA), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polylactic acid (PLA), PC/ABS, cellulose fiber, polyphenylsulfone (PPSU), thermosets, PBI-PEEK, urea, epoxies, cyanate esters, and polyurethanes.
“Petroleum well” includes liquid or gas wells designed to bring petroleum hydrocarbons to the earth's surface. Examples include oil and natural gas.
