通过不同阶段压裂充填手段来提高油气井产量时 ,当某施工层段的下部得到压裂充填后 ,这一层段的上部裂缝也已闭合或充满了地层矿物与压裂砂的混合物 ,从而影响了地层产量。压裂充填通道选择技术可一次性地提高油气井的产量 ,尤其是对有较长水平井段的油气井 ,其产量可提高大约 10倍。当施工层位的下部得到压裂充填后 ,利用通道选择技术可为该层位的上段提供第二条砾石浆液充填通道。文中介绍了如何利用McGuire和Sikora理论曲线去预测油气井的理论产量 ,对影响综合效益的一些因素 ,如减少油气井数量、利用最新技术等 ,也作了说明。
Through the different stages of fracturing and filling to increase production of oil and gas wells, when the lower part of a construction interval is fractured and filled, the upper fractures in this interval have also been closed or filled with the mixture of formation minerals and fractured sand Affected formation yield. Fracturing Fill Channel Selection technology can increase production of oil and gas wells in one go, especially for wells with longer horizontal intervals, which can be increased by about 10 times. When the lower part of the formation is fractured and filled, a second gravel slurry filling channel may be provided for the upper section of the horizon using channel selection techniques. The article describes how to use McGuire and Sikora theoretical curves to predict the theoretical production of oil and gas wells. Some factors that affect the overall efficiency, such as reducing the number of wells and using the latest technologies, are also described.
