海坨地区裂缝性储层保护技术
Protection Technology of Fracture Reservoirs in Haituo Area
摘要
Abstract
Some reservoirs of Haituo area have fractures; most of the fractures are high - angled and vertical; width of the fractures is about 0. 3mm; distribution of the fractures is wide; it's difficult to implement reservoir protection by using conventional temporary blocking technology. In view of this situation, two types of blocking agent, namely, fiber blocking agent and composite blocking a-gent, are adopted, which can form bridge plug between large pores and throats; drilling fluid preparation with temporary blocking is developed which includes filling particles and deformable particles for further blocking, thus forming temporary blocking zone. The effect evaluation experiment of temporary strength and back flow blocking removing shows that the technology has good reservoir protection function for the fracture reservoirs of Haituo area.关键词
