摘要:
 传统的杆式泵因结构设计和材质的不足，已不再满足塔河油田碳酸盐岩油藏日益严峻的深抽生产需要。针对塔河油田油藏特点，根据深抽、换泵、机械堵水、酸化压裂、TCP射孔、防胶质沥青质析出堵塞井筒等配套工艺要求，对杆式泵管柱结构进行设计优化，形成了以深抽杆式泵为核心的一体化管柱工艺技术。现场应用表明，新型深抽杆式泵允许下泵深度较常规杆式泵提高700～1000m，在换泵作业过程中不需更换泵座，在高含胶质沥青质井中配合加长尾管未发生堵塞现象，带MCHR液压封隔器和杆式泵的机械卡封堵水管柱有效抑制了套漏，射孔和酸化停喷后下入带杆式泵的抽油杆直接机抽完井，明显缩短了井下作业周期，取得了良好的经济效益和社会效益，适合在陆地油田推广应用。
Abstract:
 Conventional rod pumps with incomplete structural design and material have no longer meet the more requirements to deep pumping production of carbonate reservoirs in Tahe oilfield. According to supporting processes of deep pumping production, changing pump, mechanical water blocking, acidizing/fracturing stimulation, TCP perforation, asphaltene colloid precipitation, an integrated pumping string which includes a deep rod pump has been developed for the special reservoirs in the Tahe oilfield, based on the optimal design of rod pump string. Field application shows that the new deep rod pump can be deeper than a conventional rod pump by 700-1000m. In addition, no pump seat needs to be renewed when changing a failed pump; no asphaltene colloid precipitation has been found in the well with a lengthened tail pipe; casing leakage has been reduced on the mechanical water blocking string with MCHR hydraulic packers and a deep rod pump; and the downhole workover duration has been shortened in the well completed with a deep rod pump after perforating and acidizing. This new process is proved to provide good economic and social benefits, and suitable for application in land oilfields.
