在深盐层中通过新井造腔建储气(油)库,按照目前国内常规建库技术方案,将面临深度增加和复杂地质条件等因素引起的造腔循环压耗增大、管柱堵塞或变形失效、注采完井风险高等技术难题。针对这些难题,文中对比分析了目前常规技术方案与双井建库和大井眼建库方案的技术效果差别,结果表明双井建库和大井眼建库技术方案,在降低循环压耗、减少管柱堵塞或失效风险方面具有较大优势,是未来解决深盐层建库技术难点的可选方案。
In the deep salt layer through the new wells wells build gas storage (oil) reservoir, according to the current domestic conventional technology solutions for the reservoir, will face increased depth and complexity of geological conditions and other factors caused by cavity pressure build-up, pipeline plugging or blocked Deformation failure, injection and completion of higher risk of technical problems. In view of these problems, this paper comparatively analyzes the technical effects of the current conventional technical solutions with the construction plans of Shuangjing reservoir and Dajingkou reservoir. The results show that the technical solutions of Shuangjing reservoir and Dajingyan reservoir are of great significance in reducing the cycle pressure loss, Column blockage or failure risk has greater advantages, is the future solution to the technical problems of deep salt reservoir construction options.
