辽河油区中深层老区稠油油藏热采经历蒸汽吞吐开采后,多采用蒸汽驱方式提高采收率,但蒸汽驱油气比和原油商品率均较低。如何提高老区稠油油藏采收率已成为辽河油田急需解决的问题。以高3块为例,在经历了天然能量开采、蒸汽吞吐开采以及蒸汽驱试验后,进行火烧油层开发方式可行性的实践与研究,并确定该技术可以作为稠油老区油藏蒸汽驱后大幅度提高原油采收率的有效接替技术。
After the thermal recovery of heavy oil reservoirs in the middle and deep old areas of Liaohe Oilfield experienced steam huff and puff, more steam recovery was adopted, but the ratio of steam flooding and crude oil was lower. How to improve the recovery rate of heavy oil reservoirs in the old area has become an urgent problem to be solved in Liaohe Oilfield. Taking the high 3 as an example, after practicing natural energy exploitation, steam stimulation and steam flooding test, the feasibility and feasibility of developing fire-burning oil layer were studied. Amplitude of effective recovery of crude oil recovery technology.
