四川盆地磨溪地区龙王组气藏开发资源潜力大，但气藏储层非均质性强，气水关系复杂，不同水侵模式下的水侵主控因素尚不明确，水侵形势日趋严峻造成部分储量难以有效动用，进而影响气藏采收率。以安岳气田磨溪开发主体区块为主要研究对象，基于岩心、薄片、常规及成像测井、地震及生产动态等资料，划分了产水井类型，动静结合厘定了不同井区水侵主控因素及水侵规律。研究结果表明：①依据产水特征，可将产水井划分为快速上升型、缓慢上升型、稳定型和复合型，4种类型产水井产水特征明显不同。②不同产水类型井水侵受裂缝发育程度、溶洞型高渗层分布、构造因素和储层连通性耦合控制，产水快速上升型受裂缝发育程度主控，缓慢上升型受溶洞型高渗层分布主控，稳定型产水井储层较为均质，复合型受多种因素共同控制。③不同主控因素影响下，不同井区表现为不同的水侵模式：MX009⁃3井区水侵模式为裂缝水窜型，水侵速度快，产水量高；MX8井区水侵模式为高渗层指进型，产水量快速上升而后趋于稳定；MX10井区为视均质储层，水侵模式为边水舌进型，边水推进相对均匀；MX204井区位于气水过渡带，表现为底锥横侵型。研究成果可为提高气藏采收率以及开发技术政策的调整提供地质指导，为同类型有水气藏水侵规律研究和开发评价提供借鉴。

The Longwang Formation gas reservoir in Moxi area of Sichuan Basin has great resource potential， but the gas reservoir has strong heterogeneity and complicated gas-water relationship. The main controlling factors of water invasion under different water invasion modes are not clear， and the increasingly severe water invasion situation makes it difficult to effectively use the reserves， thus affecting the gas reservoir recovery. Based on the data of core， thin section， conventional and imaging logging， seismic and production dynamics， the types of producing wells are divided， and the main controlling factors and rules of water invasion in different well areas are determined by combining dynamic and static data. The results show that： （1） According to the characteristics of water production， wells can be divided into four types： fast rising， slow rising， stable and compound types， and the water production characteristics of four types of wells are obviously different. （2） Different water production types are controlled by the coupling of the fracture development degree， the distribution of karst cavern high permeability layer， the tectonic amplitude and reservoir connectivity. Fast-rising water-producing wells are mainly controlled by the degree of fracture development， continuous-rising water-producing wells are mainly controlled by the distribution of dissolved cave-type high-permeability layers， stable water-producing wells have relatively homogeneous reservoirs， and composite water-producing wells are controlled by multiple factors. （3） Different well areas show different water invasion modes under the influence of different main controlling factors： the water influx mode in the MX009-3 well area is fractured water channeling type with fast water influx speed and high water production； the water influx mode in the MX8 well area is the high permeability layer fingering type， and the water production rate rises rapidly and then tends to be stable； the MX10 well area is an apparently homogeneous reservoir， the water invasion mode is edge water tongue type， and edge water advance is relatively uniform； the MX204 well area is located in the gas-water transition zone， which shows the bottom cone transgression type. The research results can provide geological guidance for improving gas reservoir recovery and adjusting development technology policy， and provide reference for the research and development evaluation of water invasion law in the same type of water gas reservoir.
