乌兰花潜山火成岩储层压裂技术
|
摘要
针对乌兰花潜山火成岩储层地层连通性差,岩性致密坚硬、压后产量低等问题,开展了火成岩储层压裂工艺研究。通过优选驱油低伤害压裂液体系,采用线性胶、滑溜水等低黏度压裂液作为前置液大规模造缝、多级段塞降滤失及封堵转向等技术,形成了乌兰花潜山火成岩储层"转向与油水置换"压裂工艺,并成功进行了兰9-1X、兰42、兰9、兰45等4口井的压裂改造,压后增产效果明显,其中兰45井日增油24. 3 t。现场应用表明,"转向与油水置换"压裂工艺对基质渗透率低、裂缝连通效果差、分布不均的火成岩潜山油藏的压裂改造具有一定的指导意义。
To address the problems of igneous rock reservoirs in Wulanhua buried hill such as poor connectivity,compact and rigid lithology and low yield after fracturing,the research on igneous rock reservoir fracturing technology was carried out. By selecting oil-displacement low-damage fracturing fluid system,using low-viscosity fracturing fluid such as linear gel and slick water as preflush fluid to conduct large-scale fracturing,multistage plug loss reduction and plugging diversion technologies,the fracturing process of "diverting and oil-water displacement"for the igneous rock reservoir of Wulanhua buried hill was formed. The fracturing operations of four wells of Well Lan 9-1 X,Well Lan 42,Well Lan 9 and Well Lan 45 were successfully carried out with significant EOR performance. Well Lan45 had increased oil by 24. 3 t per day. The field applications show that the"diverting and oil-water displacement"fracturing process has a guiding significance for the fracturing of igneous rock buried hill reservoir with low matrix permeability,poor fracture connectivity and uneven distribution.
