摘要
屏蔽式暂堵技术是利用泥浆中固相颗粒在地层裂缝处形成堵塞而达到暂堵的技术。以人造裂缝岩心为研究对象,取得了裂缝堵塞的一些技术参数,包括架桥粒子粒径、粒子浓度、桥堵深度和填充粒子以及施工条件等,对岩心进行了反排效果的评价。
A technique of temporary screen plugging for fractured reservoirs strata is proposed, by which the solid particles in the mud are used to plug up the fractures. With theman-made fractured cores, some technical parameters that include the size of bridging particles, the depth of plugging and the type of fillihg fines, as well as the executing conditions have been obtained. In addition, backflushing effect is estimated experimentally.
