盐穴储气库技术的发展和应用

Development and Application of Salt Cavity Gas Storage Reservoir Technology

经过逾10a的研究与实践,形成了选址和评价、老腔改造、造腔、注采运行监测等一系列特色技术。介绍高精度三维地震解释、含盐地层岩性识别和层次分析法技术,井筒改造和形状改造技术,造腔优化设计、造腔过程监控、夹层处理和天然气回溶腔体修复技术,腔体变形监测、腔体泄漏监测、腔体垮塌及裂缝监测、地面沉降监测、温度、压力和流量监测技术。列举盐穴储气库在气源保供中的应用实例。

After more than 10 years of research and practice, a series of special technologies such as site selection and evaluation, old cavity reconstruction, cavity creation, injection-production operation monitoring have been formed. High-precision three-dimensional seismic interpretation, lithology identification of salt-bearing strata and analytic hierarchy process technology, wellbore reconstruction and shape reconstruction technology, cavity optimization design, cavity process monitoring, sandwich treatment and natural gas dissolution cavity repair technology, cavity deformation monitoring, cavity leakage monitoring, cavity collapse and fracture monitoring, land subsidence monitoring, temperature, pressure and flow monitoring technologies are introduced. The application examples of salt cavern gas storage reservoir in gas guarantee and supply are listed.
