针对葡萄花外围储层油藏丰度低、薄互层层比例大,水平段钻遇率低,常规压裂方式改造效果不理想的情况,探索薄互层水平井可控穿层压裂技术,形成外围储层人工裂缝穿层标准,为葡萄花薄互层可控穿层压裂提供合理设计标准与工艺控制依据。通过周围直井压后裂缝剖面监测及水平井压后示踪剂检测综合分析评价水平井穿层压裂情况,证实葡萄花水平井穿层压裂技术可有效实现薄互水平井钻遇层段与非钻遇层段的有效沟通,提高水平井开发效果。
In view of the low abundance of reservoir peripheral reservoirs, the large proportion of thin interbedded layers, the low penetration rate in horizontal section and the unsatisfactory retrofit of conventional fracturing methods, , Forming the standard of artificial fractures in peripheral reservoirs to provide reasonable design standards and process control basis for the controllable through fracturing of thin interbed of grape flowers. Through comprehensive analysis and evaluation of cross-well fracturing in horizontal wells by cross-sectional fracturing of post-pressure vertical fractures in vertical wells and cross-fracturing detection of horizontal well fractures, it is proved that the fracturing technology of Putaohua horizontal wells can effectively realize the metamorphic zones Effective communication between non-drilling zones to improve the development effect of horizontal wells.
