双重孔隙介质油藏水平井压裂产能影响因素分析

摘要

一些特殊和难动用地质储量采用直井开采技术往往不能达到理想的效果,而采用水平井开采技术能取的比较好的效果.对于低渗透双重孔隙介质油藏,由于油层渗流阻力大,油井泄油面积小,往往采用对水平井进行压裂的方法来提高油藏产能.%Some special and difficult to use geological reserves using vertical well mining technology often can not achieve the desired effect,and the use of horizontal well mining technology can take better results.For low permeability dual porosity media reservoirs,reservoir productivity is often increased by fracturing horizontal wells due to the high oil seepage resistance and low oil drainage area.
