摘要: 我国中东部经济发达地区天然气管道和LNG已经不能满足调峰保供的需求,建设储气库成为唯一现实 选择。目前我国中东部地区气藏、盐穴两类库址目标也不能满足储气库建设需求,含水层目标构造复杂、勘探程度低, 筛选出优质含水层建库目标开展前期评价工作难度较大。结合国内外含水层储气库建库条件分析和我国含水层目标埋藏深、构造复杂、物性差等特点,提出了适合我国含水层库址筛选评价标准和评价方法,筛选出中东部地区建库条件 相对较好的白驹含水层作为目标开展评价。研究结果表明:(1)含水层能够承受最大流体压力为15.0MPa,提压系数为1.2;(2)有效建库空间体积为3864×104m3,含气饱和度为64.7%,库容量为17.5×108m3;(3)构造顶部两口 裸眼井封堵处理不确定因素多,建库风险大。建议我国中东部地区盐岩层下伏埋深浅、物性好、水体规模大的含水层 作为重点勘探方向库址目标。

Abstract: The construction of gas storage is now the only practical solution in economically developed areas of central and eastern China since the natural gas pipeline and LNG can no longer satisfy the peak demand modulation and supply guarantee. In addition, another two types of targets, depleted gas reservoir and salt cavern in central and eastern China are not suffi cient to construct gas storage. The aquifer target has complex structure and low level of exploration, which is challenging to select favorable site and carry out preliminary evaluation. By analyzing the aquifer conditions for gas storage construction at home and abroad and the characteristics of aquifer target in China, such as great burial depth, complex structure and poor physical properties, evaluation criteria and methods for aquifer sites selection are put forward. As a result, Baiju aquifer structure with relatively good conditions for gas storage construction is selected as the study object in the central and eastern China. The results show that: (1) The maximum fl ow pressure that the aquifer can withstand is 15.0 MPa and the enhanced pressure factor is 1.2; (2) The effective space volume of gas storage is 3864×104m3, gas saturation is 64.7% and total gas storage capacity is 17.5×108m3; (3) There are many uncertain factors in the plugging treatment of the two open hole wells at the top of the aquifer structure, and the risk of gas storage construction is high. It is suggested that the subsalt aquifer with shallow burial depth, good physical properties and large-scale water body in the central and eastern China should be selected for gas storage target.
