摘要
水平井分段压裂工艺技术作为有效开采致密砂岩的技术措施,在Q地区率先应用。以Q7P1井为例,针对地层储层特点,分析了水平井裸眼滑套分段压裂改造的技术难点;从裂缝分段优化、压裂管柱、压裂液体系优选,以及施工规模等方面阐述了该工艺技术的现场应用情况,为下步致密砂岩水平井的压裂改造提供参考。
As an effective exploitation technology of tight sandstone, the multistage fracturing technique for horizontal well was firstly applied in Qiaohekou area. Taking well Q7P1 as an example, technology difficulties of the muhistage fracturing for horizontal well having open - hole sliding - sleeve were analyzed on the basis of reservoir characteristics. This paper introduces in detail the field application of the technology from aspects of subsection optimization of fractures, fracturing string, selection of fracturing fluid system, and conduction scale, etc. , which provides a reference for the next step of fracturing to tight sandstone horizontal wells.
