针对ca油田多层状砂泥薄互层稠油油藏的特点,开展了热采和非热采条件下储层变化特征研究、钻井和固井过程入井液的研究、采油工艺技术等系统保护油气层研究,了解各种变化的作用过程和原因,有效地预防现场施工中可能发生的储层伤害,从而达到储层保护、提高采收率的目的。
In view of the characteristics of multi-layered sand-mud thick interbedded heavy oil reservoirs in ca oilfield, the paper studies the characteristics of reservoir changes under both thermal and non-thermal coal mining conditions, studies on well fluids in drilling and cementing processes, and oil recovery technology Oil and gas layer research to understand the role of various changes in the process and reasons to effectively prevent on-site construction of possible reservoir damage, so as to achieve reservoir protection, improve oil recovery purposes.
