页岩气储层具有孔隙度小、渗透率低、微裂缝发育的特点，需要进行压裂才能获得理想产能。彭页HF-1井是中国石化部署在重庆境内的一口重要的预探井，根据对该井的储层特征进行分析，确定了该井储层改造的压裂模式。在此基础上，确定了该井的压裂工艺。然后通过实验，优选了压裂液和支撑剂。彭页HF-1井根据压裂设计进行施工，整个施工共分12段进行，共加入压裂液16211.6 m3，石英砂1332.7 t。压后通过测试，取得了20000 m3/d的高产。该井压裂施工获得成功，产能测试获得突破，证实了页岩储层的含气性能，该套页岩气压裂工艺适合该区块储层，同时也对其他区块的页岩气压裂施工也具有较好的借鉴意义。

Shale gas reservoir with low porosity,low permeability,and fractures development and other characteristics must be stimulated in order to achieve commercial development. Well Pengye HF-1 is one of the key shale gas exploratory wells of Sinopec. According to analysis of the reservoir conditions,the fracturing model of the well was determined. On the basis of this,we decided the fracturing crafts. Through experimental study,fluid and proppant selection were optimized. Well Pengye HF-1 was fractured according to the fracturing design,and the whole progression was divided into 12 sections. The treatment fluid is 16 211.6 m3,the accumulated proppant is 1 332.7 t. After the test,the well yields 20 000 m3/d. The well fracturing achieved great success and deliverability test obtained breakthrough,which not only proved the performance of shale containing gas and that the fracturing technology is suitable for the reservoir,but also provided a good references in other shale gas reservoir stimulation.
