摘要
研究华庆地区长6储层超低渗油藏裂缝分布规律。通过井间微地震、井间示踪剂、干扰试井以及生产动态相结合的方式对裂缝进行准确识别,明确该井区已发育裂缝26条,以北东向为主,北西向次之,与现今地应力方向一致。
This paper studies the distribution law of fractures of Huaqing ultra-low permeability reservoir in Chang 6 formation.Based on the crack formation reasons,through crosswell tracer,interference of well test and dynamic combination method,it identifies fractures accurately.It finds out 26 fractures developed in this area,generally in Northeast,few nearly Northwest.The orientation consistents with the present ground stress direction.
