摘要
瓦窑堡油田元峁区块长2油藏在考虑了天然水侵量的情况下,还有近3万m3的亏空,但现场反映注水压力居高不下,无法完成配注要求。本文通过储层敏感性实验、注入水水质分析、配伍性研究及污水处理剂室内评价等,得出了导致注水井注水压力居高不下的主要原因是污水处理剂配伍性差和细菌堵塞。
Chang2 reservoir in Yuanmao block of Wayaobao oilfield, taking the case of natural water influx into account, there are nearly 30,000 cubic meters of the deficit, but onsite technical staffs reflected that the pressure of injection is very high, they can＇t complete the command of injection requirement. By experiment of reservoir sensitivity, analysis of injected water quality, research of compatibility and laboratory evaluation of sewage treatment agent, ect.Derived the main reason that caused the high pressure of injected well is sewage treatment agents incompatibility and bacterial jam.
