摘要
塔河油田主力区块为具有底水的奥陶系碳酸盐岩岩溶缝洞型油藏。目前塔河油田机抽井平均泵挂深度达2 606 m,由于部分井注水条件差,不得不靠加深泵挂放大生产压差保证连续生产。同时深抽时需要配套大型抽油机,大量H级抽油杆、玻璃钢抽油杆和EUE油管,增加了作业和生产成本。为解决这一难题,塔河油田引进了抽油机减载器进行试验应用,成功实现了小型抽油机的深抽。通过应用证明抽油机减载器能够有效地减轻抽油机驴头载荷,降低各级抽油杆的应力和变形,实现抽油机减载节能采油和延长抽油杆及地面设备使用寿命,有效地节约生产成本[1]。
The main block of Tahe oilfield is the Ordovician carbonatite karst gap reservoir with bottom water. At present, the aver- age pump setting depth in Tahe oilfield is 2 606 meters. Due to the poor injection conditions of some wells, the deepening of the pump setting depth and the increase of the drawdown pressure is needed for continuous production. Meanwhile, that deep pumping needed to equip large-size pumping units and numerous H-class rods, FRP rods and EUE tubings increased operations and pro- duction cost. To solve this problem, Tahe oilfield introduced the load shedding devices and successfully implemented deep pump- ing of small-size pumping unit. It is proved that load shedding devices can effectively reduce the load of horse head, lower the stress and the strain of rod at all levels, realize the load shedding energy-efficient production, increase the service life of sucker rods and ground equipments and reduce the production cost.
