The present embodiments relate to a double pin connector with hydraulic connect and seal assembly for use in downhole drilling operations.
A need exists for an intelligent completion system for use inside a multi-zone hydrocarbon well.
There further exists a need for a pin connector with seal assembly that can be pulled after use, taken apart, cleaned, and reused.
The present embodiments meet these needs.
The detailed description will be better understood in conjunction with the accompanying drawings as follows:
The present embodiments are detailed below with reference to the listed Figures.
Before explaining the present apparatus in detail, it is to be understood that the apparatus is not limited to the particular embodiments and that it can be practiced or carried out in various ways.
The present embodiments relate to a double pin connector with hydraulic connect and seal assembly. The double pin connector with hydraulic connect and seal assembly has a top portion of a double pin hydraulic connect and seal assembly.
The top portion of the double pin connector and an upper tubular portion engages an intermediate tubular portion. The intermediate tubular portion has an upper flow path in fluid communication with the first hydraulic connector and a plurality of seals comprising at least one second hydraulic flow path seal.
The top portion has a plurality of upper concentric seals disposed on an outer surface of upper tubular portion and an outer surface of the intermediate tubular portion. The first, second, and third concentric seals can be an elastomeric or non-elastomeric seal. Exemplary elastomeric seals can be purchased from OEM™ Corporation, in Houston, Tex. An exemplary non-elastomeric seal can be purchased from Greene Tweed from Houston, Tex. supplies usable concentric seals for this embodiment.
The first concentric seal, the second concentric seal, and the third concentric seal can be similar to each other. A lower tubular portion fastens to the intermediate tubular portion, and the lower tubular portion comprises an intermediate hydraulic flow path in communication with the upper hydraulic flow path.
A first hydraulic connector is in fluid communication with a fluid supply and fastened to the upper tubular portion. An upper anchor is fastened to the lower tubular portion and a filter, such as a screen with a filtration ranging from about 0.5 microns to about 100 microns. An exemplary filter is commonly used in the industry, and can be purchased from Mott Corporation, located in Farmington, Conn. The filter is secured to the lower tubular portion for providing filtration of the intermediate hydraulic flow path.
The double pin hydraulic connect and seal assembly has a bottom portion. A lower anchor fastens to a first lower tubular body of the bottom portion.
The first lower tubular body has a lower port cover. The port cover can be made out of metal. The port cover can have a diameter from about 2 inches to about 7 inches. A lower actuator surrounds an actuator guide, which is within the lower tubular portion. The actuator can be a spring, a pressure actuator, an electrical actuator, a mechanical actuator, or similar commonly used actuator.
A second lower tubular body is secured to the actuator guide. The second lower tubular body has a lower tubular body face, an outer pin with an outer pin face and fastens to the first lower tubular body.
The second lower tubular body contains a lower hydraulic flow path with a first lower port seal, spaced apart from a second lower port seal with a lower port spacer.
A second hydraulic line connector is in communication with the lower hydraulic flow path, and a lower tubular body seal is disposed between the second lower tubular body and the first lower tubular body.
The second hydraulic line connector connects to a downhole tool, such as a single line sliding sleeve down hole tool assembly, an artificial lift mandrel, and commonly used hydraulic down hole equipment.
The intermediate hydraulic flow path is in fluid communication with the lower hydraulic flow path when the top portion of the hydraulic connect and seal assembly lands within the bottom portion of the hydraulic connect and double pin sub. After the top portion is landed in the bottom portion the down hole tool can be actuated.
A first hydraulic flow path seal can be disposed between the upper tubular portion and the intermediate tubular portion. Further a first seal ring can be disposed between the first hydraulic flow path seal and intermediate tubular portion.
A second seal ring can be disposed between the upper tubular portion and second hydraulic flow path seal.
An upper landing ring can be fastened to the upper port cover. The upper port cover can be fastened to the lower tubular portion. A locking wire can connect the upper port cover to the upper landing ring. An upper fastener can connect the upper port cover to the lower tubular portion.
A barrier seal assembly can be disposed between the lower anchor and the first lower tubular body. The barrier seal assembly can have a barrier seal disposed within a seal housing.
A first lower seal ring and second lower seal ring can be disposed between the first lower tubular body and the second lower tubular body.
The intermediate hydraulic flow path and the upper hydraulic flow path are in continuous fluid communication. The upper anchor removably fastens to the lower anchor when the top portion of hydraulic connect and seal assembly lands within the bottom portion of hydraulic connect and double pin sub.
In another embodiment the seal assembly can be removed and a plurality of hydraulic connectors can communicate with a plurality of hydraulic flow paths with the double pin connector.
