Abstract

The Dengsi gas reservoir in the Moxi block of the Anyue super large gas field in the Sichuan Basin is a high-temperature and atmospheric pressure large-scale lithologic stratigraphic composite enclosed gas reservoir. The storage space is mainly composed of small and medium-sized karst caves and various types of dissolution pores. The overall performance of the reservoir is low porosity, low permeability, and strong heterogeneity. The fourth gas reservoir in the Moxi platform edge zone is currently in the early stage of stable production, and there are problems such as interference between some well groups, poor reservoir seepage characteristics of some gas wells, blockage of some gas wells, water invasion, etc., which result in limited production. The dynamic reserves of the stacked gas wells with well control radii have significant differences in calculation results at different periods, and the dynamic temperature and pressure monitoring system for gas well production is incomplete, There is an urgent need to establish a unified production dynamic monitoring system suitable for the four gas reservoirs along the Moxi platform edge.

Keywords: Moxi Block; Deng Si Gas Reservoir; Dynamic Monitoring; Interwell Interference.
