摘　　要：白云质泥岩储层不同于常规的砂岩储层和碳酸盐储层,该类储层天然裂缝发育、泥质含量高,压裂过程中主裂缝形成困难、支撑剂嵌入严重,目前没有较好的压裂改造技术。达平3井储层大部分属于白云质泥岩储层,该井通过对白云质泥岩储层的特性研究,探索应用水力喷射分段压裂工艺,优化压裂施工参数,优选压裂液和支撑剂,成功进行了压裂施工,压后取得了一定的增产效果。该井的有效性试验为下一步该区块白云质泥岩储层的压裂改造提供了技术思路和施工经验。Dolomitic mudstone reservoir is different from any conventional sandstone reservoir and carbonate reservoir, the reservoir is development of natural fracture and is high of shale content, in the fracturing process the main crack forms difficult, proppant embeds serious, there is no good fracturing technology at the moment. The most of Daping 3 well reservoir belongs to dolomitic mudstone reservoir, through the research of dolomitic mudstone reservoir characteristic,exploreing the application of hydraulic-jet staged fracturing technology, opti- mizing fracturing construction parameters, optimizing fracturing fluid and proppant, the frac- turing construction is successful, and it has obtained the certain effect after fracturing. The validity test of the well provides the technical ideas and construction experience for the fracturing transformation of this block dolomitic mudstone reservoir for the next step.
