碳酸盐岩底水气藏型储气库动态特征及水淹机制
|
摘要
储气库注采气能力、库容及工作气量是衡量储气库能力的重要指标,储气库动态特征分析是评价储气库能力的重要手段。基于某碳酸盐岩底水含硫气藏改建储气库(A储气库)的多周期注采生产情况,通过系统分析储气库运行动态特征,评价了水平井注采气生产能力,利用两种方法对储气库库容进行复核,分析了气藏H2S质量浓度变化,评价了脱硫运行方式,结果表明:该储气库单井产能高,库容落实程度高,具备高效开发潜力,但仍需探索脱硫运行方式。研究分析了A储气库生产中出现的AH1井水淹停产问题的形成机制,提出了恢复气井生产能力的具体方案,并成功应用于现场。研究成果对中国碳酸盐岩底水气藏型储气库生产运行及能力评价具有指导作用。(图1,表5,参20)
Injection-production gas capacity, storage capacity and working gas volume are important indexes for measuring the capacity of underground gas storage(UGS). Dynamic characteristics analysis is an important means to evaluate the capacity of UGS. Based on the multi-cycle injection-production performance of a certain UGS rebuilt from the carbonate sour gas reservoir with bottom water, the injection-production capacity of horizontal well was evaluated by analyzing the dynamic characteristics of UGS during its operation. Then, the storage capacity of UGS was checked by using two methods. Finally, the change of the mass concentration of H2 S in the gas reservoir was analyzed, and the operation mode of desulfurization was evaluated. It is indicated that this UGS is high in single well productivity, storage capacity implementing degree and efficient development potential, but its operation mode of desulfurization still needs exploring. What's more, the water flooding mechanism of Well AH1 leading to its off production was studied, and the specific technological measures for restoring the production capacity of gas well were put forward and successfully applied on site. The research results play an important role in guiding the production, operation and gas storage capacity evaluation of UGSs rebuilt from carbonate gas reservoirs with bottom water in China.(1 Figure, 5 Tables, 20 References)
