2) deep oil displacement and profile control agent
深部调驱剂
1.
A deep oil displacement and profile control agent CDG for features of Shengtuo Oilfield was prepared with partially hydrolytic polyacrylamide (HPAM) and organic chrome cross linker XE - 1 as main materials.
根据胜坨油田高含水期提高原油采收率的要求,针对其高温、高矿化度、非均质性严重等油藏地质特点,在探讨弱凝胶调驱技术原理的基础上,制备了以部分水解聚丙烯酰胺(HPAM) 和有机铬交联剂XE-1为主剂的CDG深部调驱剂体系。
3) reservoir permeability control/oil displacement
深部调剖/驱油
4) In-depth Profile Modification Particle
深部调驱颗粒
6) compound deep profile modification system
复合深部调驱体系
1.
According to the geologic feature and waterflood performance of low-permeability fractured reservoir in Panguliang Chang-6 reservoir of Changqing Oil Field,a compound deep profile modification system composed of pre- crosslinked particle/waterflood fluid diversion agent/polymer gel was prepared.
针对该油藏地质特征和见水状况,研制了预交联颗粒/水驱流向改变剂/聚合物弱凝胶复合深部调驱体系,其中预交联颗粒/水驱流向改变剂具有较高的膨胀率,发挥了深部调剖作用,有效封堵大裂缝出水通道;聚合物弱凝胶主要发挥了驱油作用,有效启动中小裂缝中剩余油。
