Feasibility Evaluation and Key Design Methods for Underground Gas Storage Construction in Edge-Bottom Water Gas Reservoirs
摘要
Abstract
After the commissioning of gas storage facilities in edge-bottom water gas reservoirs,issues such as insufficient storage capacity and reduced peak shaving capacity often arise.In response to the differentiated vertical water invasion distribution and complex fault characteristics in block M,a differentiated water energy modeling method was adopted to simulate the impact of 3.2 to 14.0 times of water energy on the operation of the gas storage.The static evaluation of fault SGR was combined with dynamic failure prediction pressure,and the safe operation pressure of the gas storage was designed based on the"short board effect".Various well patterns were simulated and compared.Ultimately,a composite well pattern featuring"horizontal wells as the mainstay and vertical wells as a supplement"was adopted,with the deployment of 22 injection-production wells.A water control strategy of"low-speed slow injection at high structural positions"was implemented,leveraging the well pattern dominated by horizontal wells to enhance injection-production efficiency.The daily gas injection capacity of a single well reached 340 000 cubic meters,which is 2.1 times that of a vertical well.Practice has confirmed the feasibility of constructing gas storage facilities in edge-bottom water gas reservoirs,and this study provides important reference value for the optimal design of similar gas storage facilities.关键词
