Tungsten Carbide Equipment Solve Partial Wearing Problem

Recently, the Yumen Oilfield Oil Production Plant oil duck children gorge team technical team leader Li Ning serious stare duck K1-10 wellsite conceal his face is delighted: "Since the use of this device, which I often need surgery well made no been ill, and now we can rest assured that in other to promote the use of the well. "
Duck children Gorge Reservoir Oil Production Plant complex geological structure, oil prone eccentric wear phenomenon. Previously, in order to prevent eccentric wear caused by oil bar broken off, oil wells team technical team to install anti-eccentric wear equipment. Employees also use the opportunity well underground work, from a downhole sucker rod section hoop, pump, tubing head thread and other downhole equipment to conduct a comprehensive inspection. However, anti-bias milling equipment still could not really solve the oil well pumping unit section hoop, threaded tubing head appeared eccentric wear problems. Especially in recent years duck children gorge horizontal wells increased, accounting for 70% of new drilling, pump hanging in 1900-2100 meters, displacement of up to 200 meters above the bottom, resulting in serious eccentric wear rod, using up more than 120 days will be break off occurs.

Since the beginning of this year, for the control of oil wells due to the occurrence of breaking off caused by multiple rounds lie well, duck child Gap oil technology group team counting finer benefits account. And repeated the repair and replacement of equipment, is bound to increase costs, affecting the normal production wells.
After then, the duck child Gap oil oil drilling teams to coordinate the Institute of plant and machinery, and the geological structure of the reservoir section hoop, tubing head material such as a comprehensive analysis of the carbide homemade device. Grindability in the well area installed in the underground ring segment added centralizer re-optimize the portfolio by carbide strength and good finish, reduced wear resistance. Duck child Gap oil production crew through an annular segment downhole added centralizer re-optimize the adjustment, prevent breaking off the hoop section, extending well exemption period.

Li Ning said: "We selected four sections hoop and tubing head screw serious eccentric wear wells may be used, the effects were good, especially the duck duck K1-10 and K1-15 well well, since after the equipment installed on the carbide never happened broken off. Tungsten carbide equipment not only solves the problem of partial wear well, but also reduces the cost of repair of oil wells. " Next, duck children gorge on oil production crew will be easy to promote the use of eccentric wear wells carbide devices.
