The Deng2 gas reservoir in the Gaoshiti block has abundant reserves and is the main stratigraphic system produced in the undeveloped area of Anyue gas field during the 14th Five Year Plan period of Southwest Oil and Gas Field Company. However, there are currently two major problems that restrict further exploration and development of the Deng2 gas reservoir: firstly, the development of pores and fractures of different scales, resulting in extremely strong planar heterogeneity of the gas reservoir; The second is to test the water production of the GS6 well in the lower part of the structure, with a daily output of 72.6 cubic meters, which reveals the risk of bottom water invasion in the Deng2 gas reservoir. In response to these two major issues, this article comprehensively utilizes static geological data such as seismic and logging, as well as dynamic data related to production characteristics, and combines dynamic and static data to conduct water body size evaluation, water body activity evaluation, interlayer sealing test, and water invasion mechanism simulation test to conduct early water invasion risk assessment in the research area. It is clear that the energy and activity of the water body in the Deng2 gas reservoir are small, the overall water invasion risk is weak, and the local water invasion risk intensity on the plane is different. Based on various geological and dynamic factors such as water body characteristics, crack development characteristics, and interlayer characteristics, four types of water invasion risk areas are divided, and two types of advantageous water invasion channels are identified.
