致密油层压裂缝长期导流能力影响因素研究

Research on tight oil reservoir long-term conductivity of fractures

通过实验研究致密油层砂岩压裂支撑缝在不同的应力条件下的导流能力,并研究了支撑剂类型以及粒径对支撑缝长期导流能力的影响。结果表明,陶粒支撑缝导流能力更强,且粒径较大的陶粒支撑缝导流能力更强。

Conductivity oftight oil reservoir fracturesunder different pressure was researched by experiments.And influences of type and grain size ofpropping agenton fracture long-term conductivity were studied.Test results indicate that conductivity of fractures proppedby ceramsite is greater;and the larger the grain size of propping agent,the greater the conductivity of fractures is.
