水平井体积压裂技术研究与应用

Research and application of volume fracturing technology in horizontal wells

M区块边部区域储量品位低,直井常规压裂开发效果差,储量动用状况差,为此开展水平井体积压裂技术研究,包括体积压裂所需地质条件、体积压裂适应性分析、水平井部署参数优化等,指导3口水平井部署实施,平均单井日产油15吨以上,阶段累增油3.2万吨,提高采收率1.25%,实现难采储量有效动用,低油价下实现降本增效目的。

The reserves in the edge area of block M are of low grade,the conventional fracturing development effect of vertical wells is poor,and the reserves production situation is poor.Therefore,the research on volume fracturing technology of horizontal wells is carried out,including the geological conditions required for volume fracturing,the analysis of volume fracturing adaptability,the optimization of horizontal well deployment parameters,etc.,to guide the deployment and implementation of three horizontal wells.The average daily oil production of single well is more than 15 tons,and the cumulative oil production in each stage is 32000 tons 25%,realize the effective production of difficult to recover reserves,and achieve the purpose of cost reduction and efficiency under low oil price.
