摘要
以“水平井+多段压裂”为核心的储层改造技术已成为中国油气开发向非常规等领域拓展的关键技术,目前针对山西马必区块井区,各簇射孔是否均匀开启无法确定,每簇起裂、裂缝延伸、进液进砂、支撑剂铺置情况不明。引进广域电磁法裂缝监测技术对桥射联作工艺优化和完善,其优化结果以3簇为主,簇间距为40m左右,一次暂堵,120m^(3)支撑剂,2000m^(3)液体左右,15m^(3)/min排量,裂缝半缝长就可以达到80~100m,即可满足220m井间距的要求。为下步压裂优化设计、井网部署或井网调整提供了依据。
Reservoir simulation technology based on horizontal wells with multi-stage fracturing has become a key approach in China's expansion into unconventional oil and gas development.In the Mabiz Block of Shanxi,it remains unclear whether perforation clusters are uniformly activated,and the initiation,extension,fluid and sand injection,and proppant distribution of each fracture are difficult to determine.To address these challenges,the wide-area electromagnetic fracture monitoring technology is introduced to optimize the bridge plug and perforation fracturing process.The optimization results suggest a configuration primarily based on three perforation clusters with a spacing of approximately 40 meters,using a single temporary plugging stage.The parameters include around 120m^(3)of proppant,2,000m^(3)of fracturing fluid,and a drainage rate of 15m^(3)/min.This setup can achieve a fracture half-length of 80-100 meters,meeting the 220-meter well spacing requirement.The results provide a solid foundation for future fracturing design optimization,well pattern deployment or adjustment.
