摘要:
同井注采技术是一种针对特高含水油井的有效稳油控水方法。本文研究的有杆泵同井注采系统由采出泵、密封活塞、桥式分隔器、注入泵和井下油水分离器等部分组成,能够利用重力作用在井下将油水进行分离,分离后的水直接被注入到地层中,分离后的富含油液被举升至地面,从而降低采出液中的含水量。基于同井注采系统的复杂受力情况,利用弹性力学理论知识和数值方法,建立了有杆泵同井注采系统的动力学模型并提出相应的显式差分解法。基于Visual Basic平台编制同井注采系统动力学仿真程序,并利用现场实测数据验证了理论模型正确性及实用性,为同井注采系统的杆柱力学分析和故障诊断研究奠定了理论基础。
Abstract:
The single-well injection-production technology is an effective method of stabilizing oil and controlling water for ultra-high water-cut oil wells. The single-well injection-production system with sucker-rod pump consists of production pump, sealing piston, bridge packer, injection pump and downhole oil-water separator and so on. The oil and water can be separated by gravity in the downhole, and the separated water is injected directly into the formation, while the separated oil-rich liquid is lifted to the ground, thereby reducing the water-cut of the produced fluid. Based on the complex stress condition of the single-well injection-production system with sucker-rod pump, the dynamic model of this system is established and the corresponding explicit difference method is proposed by using the elasticity theory and numerical methods. Based on Visual Basic platform, the dynamic simulation program of the system is compiled, and the correctness and practicability of the theoretical model are verified by the field measured data, which lays a theoretical foundation for the mechanical analysis and fault diagnosis of the rod-string in the single-well injection-production system with sucker-rod pump.
