Hydraulic anchor packer, packer, investigation of things Petroleum Technology

DB-90 at the bottom of a tee, uses DB- bottom tee mounted on the lower portion of the column pump, oil and water wells division process string matching tools, as pump has been started on the movement of oil, started to close down. Second, under the structure of joints, couplings, tee, the middle joint, the joint. Third, the principle that DB- tee mounted on the bottom of deep draw hydraulic anchor packer packer coupling between the bottom of the pump, the pump and lower motor driven ball on the bottom of the tee Kai Kai next to the ball and ball seat to seal, seal reliable, easy to use, to increase production. Safety joint is the joint connection in the drilling, workover, testing, cleaning, fracturing, acidizing and other operations in the column for special purposes, when the string work, can withstand tensile, compressive and impact loads, and to ensure that the column smooth. When the string sticking, safety joints first disengaged from Y445 series packer, the column from above the joint, re-processing the lower portion of the downhole tool string packer, the next step to simplify operating procedures. Second, the structural principle of the tools are the joint Aprons, under the joint insurance nails and other components. Disable well string sealing technology application Recommend oilfield development into the late packers, part of the oil wells due to the geological, engineering and other reasons retirement, long-term shutdown condition. The previous practice of the oil sector, cement back about 200 meters high and downhole cementing plug separately, then installed at the wellhead head to block the way. While this approach is safe, but there are shortcomings, mainly: 1, bad wellhead casing cement plug above the environment, not only easy to rust scrap, and once wellhead head stolen, the segment casing can easily be stone bricks and other debris landfill, for secondary use later cause a lot of obstacles. 2, corking process complexity and high cost, and can not detect and release wellbore pressure, the secondary use of required drilling plug. 3, wellhead deep cement plug construction site is not well protect the casing; the secondary use of shallow drilling Saiga small load carrier, not construction.
