摘　　要：四川盆地的碳酸盐岩广泛沉积,而GM井区的灯四气藏是主要的产能贡献区域,且地貌非常复杂,这些因素导致了该区域内储层的储集空间复杂,储层的非均质性很强,而且储层品质和发育位置之间存在很大的差异。为了更好地理解这些储层的差异,以便进行储层改造和优化开发政策,急需开展灯影组碳酸盐岩的三维地质建模研究。经过对构造建模、属性建模和天然裂缝建模方法的优化,建立了一个全面的三维地质模型。建模结果对不同井之间的储层预测具有高度可信度,并与研究区的实际地质情况相符。Carbonate rocks are extensively deposited in the Sichuan Basin,and the Lampsi Gas Reservoir in the GM Well Area is the primary contributor to production capacity.The terrain in this region is highly complex,leading to a complex storage space for reservoirs,strong reservoir heterogeneity,and significant variations in reservoir quality and development locations.In order to better understand these differences in reservoirs for the purpose of reservoir modification and optimizing development policies,there is an urgent need to conduct a three-dimensional geological modeling study of the Lampsi carbonate rocks in the GM Well Area.This article,through the optimization of structural modeling,attribute modeling,and natural fracture modeling methods,has established a comprehensive three-dimensional geological model.The modeling results have a high level of credibility in predicting reservoirs between different wells and are consistent with the actual geological conditions in the study area.
