中原油田濮城油区部分井层岩性类型以白云质泥岩为主，微裂缝及孔洞发育，但总体上孔渗性较差，经分析认为剩余油潜力较大，决定对水平井濮1-FP1井进行分段压裂改造。通过对储层物性研究、测试压裂分析及压裂软件模拟进行压裂参数优化，确定了适合该井的分段压裂施工参数，优选了压裂液和支撑剂，成功地完成了十段压裂施工，注入总液量2975m3加入支撑剂308m3，压后取得了一定的增产效果。该井多段压裂工艺的成功应用为下一步该区块白云质泥岩储层的压裂改造提供了依据和施工经验。

Some reservoir in Pucheng area of zhongyuan oilfield is dolomitic mudstone with mangy microfracture and pore space,but its permeability and porosity are very low.Consider- ing its huge remaining oil potential, it is determined to implement multistage hydraulic frac- turing at P1-FP1 well.We researched reservoir quality,analysed the minifrac and optimized fracturing parameters by fracturing software to acquired the appropriate fracturing operation parameters,and selected the optimal fluid and proppant.The field application has been suc- cessfully completed,and a total of 2 975 m3 fluid was pumped down into hole with 308 m3 proppant added, and it has obtained the certain effect after fracturing.It will provide the tech- nical basis and operation experience for the fracturing of the dolomitic mudstone reservoir.
