Y gas field volcanic rock edge and bottom water gas reservoir supplementary pore pressure geological and development characteristics

As the understanding of the development law of the edge-bottom water gas reservoirs in the Y gas field deepens, the relationship between the energy of water in gas wells, the contact relationship between gas and water, and water discharge after reaming and fracturing is summarized. The potential and feasibility of measures for edge-bottom water gas reservoirs are evaluated, and reaming and fracturing measures are selected to achieve good production effects. Some understanding has also been obtained. Based on the energy of water in gas wells and the contact relationship between gas and water, the reaming and fracturing measure boundary of gas wells is initially divided, providing reference and basis for the selection and design of reaming and fracturing measures for edge-bottom water gas reservoirs in the future.
