摘要
塔河油田油井深度普遍在5 350～6 600 m，且以裸眼完井为主，打捞落鱼难度大，特别是油井内抽油杆随油管一并断脱形成复杂落鱼，进一步加剧打捞难度。为提高抽油杆打捞成功率，研制出一种新型抽油杆打捞筒，该装置由引筒、翻板及套铣筒3部分组成，引筒引导落鱼逐步进入翻板及套铣筒，实现打捞抽油杆下部接箍的目的。通过在TH10341井应用抽油杆打捞筒6次，成功捞获井筒内全部弯曲抽油杆，提高了修井进度，减少了作业成本，恢复油井产能5 400 t，创造效益864×104元。
Abstract
Oil wells in the Tahe oil field are usually 5 350-6 600 m deep with open hole completion, making sucker rod salvage very difficult, especially when sucker rod and oil tube break and fall off together. A new socket for sucker rod was developed, composing of guiding cylinder, turning plate and sleeve milling cylinder, to improve salvage success rate. The guiding cylinder helps sucker rod gradually enter the turning plate and sleeve milling cylinder, realizing the coupling of sucker rod. The new socket was applied 6 times in well TH10341, and successfully retrieved all bending sucker rods in wellbore, which improved repairing progress, reduced operation cost, recovered oil capacity by 5 400 t, and created benefits of 864×104 yuan.
