摘要
为了M2区块致密油开采能够实现产能新突破,满足提交石油控制地质储量的要求,对该区块新钻的5口水平井体积压裂先导性试验效果进行综合分析。通过储层物性特征、砂体展布特征、压裂施工参数及返排制度4个方面对比分析,物性基础是压裂效果好坏的主导因素,缩小簇间距能够有效地提高压裂改造效果。该分析结果可为M2区块致密油规模高效开发提供借鉴。
In order to realize a new breakthrough in production for tight oil production in M2 block and meet the requirements of obtaining controlled geological reserves for oil reservoir,the pilot test results of volume fracturing in 5 newly drilled horizontal wells in this block were comprehensively analyzed.Through the comparison and analysis of reservoir physical property,sand body distribution characteristics,fracturing operation parameters and backflow conditions,it is concluded that reservoir physical property foundation was the dominant factor of fracturing effect and reducing well cluster spacing could effectively improve the effect of fracturing.The analysis results can provide an important reference for the scale and high efficient development of tight oil in M2 block.
