通过对志丹探区旦八区长6储层压裂地质特征的认识及压裂基础分析,提出长6储层的压裂工艺技术优化模式;针对长6储层低渗特低渗的特性及本地区地应力、岩石力学性质及地层破裂压力梯度等方面的特征,结合该地区压裂工艺技术改造的现状,对旦八区长6储层压裂工艺参数进行了优化,增强了旦八区长6油层压裂施工效果,提高了单井产量。
Through the understanding of the fracturing geological characteristics of Chang 6 reservoir in Zhidan exploration area and the basic analysis of fracturing, an optimization mode of fracturing technology for Chang 6 reservoir is proposed. According to the characteristics of low permeability and low permeability of Chang 6 reservoir And the features of local stress, rock mechanics and pressure gradient of formation rupture, combined with the status quo of technological renovation of fracturing in this area, the fracturing parameters of Chang 6 reservoir in Dan 8 area were optimized, District 6 reservoir fracturing effect, improved single-well production.
