The present invention relates generally to an improved drilling mud screen system and methods thereof and, more particularly, to an improved drilling mud screen system with a drilling mud screen puller/installer tool and methods thereof.
Many drilling rigs use drill pipe mud screens that are in-line with the drilling assembly. Typically, drilling mud screens, commonly Type 3 drilling mud screens, are installed on the drill floor or at the bottom of the drill string. If the drilling mud screen is installed on the drill floor, the drilling mud screen must be reinstalled or replaced every time a section of stand pipe is added to the drill string. In other words, the drilling mud screens must be installed at the top of each 90-foot stand of pipe above the rig crew. As each stand of drill pipe is drilled down to the derrick floor, the top drive sub-connection is separated from the drill pipe stand connection and the drilling mud screen is installed to the top of the next stand of pipe going in the hole. This is a dangerous practice that can result in accidents to the crew below.
Although the Type 3 drilling mud screen appears to work for single-shoulder API rotary shouldered connection types, it does not work for proprietary double-shoulder high-strength connection types that eliminate the space where the drilling mud screen is typically located inside the pipe. Instead, the nose of the double-shoulder pin connection on the top of the drive sub-connection is decreased to the exact width of the drilling mud screen flange, so that “theoretically” the nose of the double-shoulder pin connection may have the same contact inside the mating drill pipe box and same shoulder bearing stress at optimal connection make-up torque as it would in an unmodified assembly. Further, the dimensions of the shortened nose of the double-shoulder pin may not be adequate for the selected drilling mud screen flange. When the dimensions of the shortened nose of the double-shoulder pin are outside the acceptable connection tolerances of about ±0.000-inch to about ±0.0010-inch, the mating pin and/or box is damaged. Further, rig crews often forget to install the drilling mud screen. This oversight frequently results in damage as the shortened nose of the double-shoulder pin continuously tries to make-up inside the box but fails. These are dangerous practices that can result in drilling mud leaking onto the drilling rig floor creating a slip hazard and/or in a double-shoulder connection failure. Further, this is an expensive practice that rapidly consumes drilling mud screens long before they need to be replaced.
If the drilling mud screen is installed at the bottom of the drill string, the drilling mud screen must be brought to the surface to be replaced. This is an inefficient practice that can results in lost drilling time.
Thus, an improved drilling mud screen system with a drilling mud screen puller/installer tool is needed to eliminate these problems.
