Abstract

Since the Well Z2 seam system has attracted much attention due to its unique geographical location，completion method and excellent social and economic benefits.Studying the structure of the fracture cavity system and the water intrusion model are of great significance for the terminal management and predictive recovery of gas reservoir production.Therefore，based on the dissolution characteristics of Maokou and Qixia Formations，the production characteristics of the well and the discussion of the dynamic analytical method of reserves and water invasion，this paper expounds the typical geological characteristics of the fracture-cave system from many aspects，demonstrates the basic structure and scale of the fracture-cave system of Qixia Formation，and gives the fracture-cave structure and water invasion mode of the well.And the nonlinear material fitting method，AIF method and replenishment material balance method were used to study the water intrusion dynamics of Well 2，and the influence of the fracture cavity structure on production was predicted and its production potential was predicted.According to its historical role，this paper systematically summarizes the historical position and role of this well in the development of fractured-vuggy gas reservoirs，which has a certain guidance for the development of similar fractured-vuggy gas reservoirs.

Key words： Fractured-vuggy system; Z2 Well; Water intrusion dynamics; Qixia Formation; Typical
