摘要

地下储气库(UGS)是解决天然气供给与需求不平衡问题的重要设施。枯竭气藏是建设UGS的理想储层,而储层的综合性能决定了建立UGS的可行性。气藏的存储能力是衡量UGS运行效果的重要指标,为正确判断板中北BZ气库存储能力变化特征,文章综合分析了研究区储层发育特征,对BZ气库主力储层压力应变数据进行了统计和对比。借助数学模型分析储层孔隙结构压力应变的影响因素,提出原始孔隙度、气库运行压力与气库储层压力应变特征存在相关性。实际生产历史拟合检验结果表明,所提出的分析方法和数学模型有助于正确地定量认识气库运行规律,为实际生产管理中制定相应的运行方案提供了一种有利的分析手段。

Abstract

Underground Gas Storages (UGS) are widely used to store the surplus of produced natural gas during periods of low demand, and to relieve the pressure during periods of high demand. A depleted natural gas reservoir is generally the ideal choice for the UGS. The proper selection of a depleted gas reservoir is essential to the stability of the UGS in the long run. The storage ability is an important index for the performance of the gas storage. In order to analysis the stability of the storage ability of the UGS in BZ area, the development characteristics of the main reservoir are studied, with the pressure strain data of the reservoir analyzed and compared. The effect of the pressure strain on the porosity is evaluated by using mathematical formulas, and it is believed that the original porosity and the operation pressure are related with the effect of the pressure strain on the UGS. The case production history fitting of the gas storage has verified the analytical method and the mathematical chart board, which may offer an accurate and quantitative analysis of the storage ability in the UGS, and provide an analytical tool in the practical production management.
