摘要

合兴场—丰谷地区沙溪庙组气藏以其较大规模三角洲沉积和较大油气勘探开发潜力引起关注,而 前人针对该区沉积微相展布特征及有利相带的研究甚少。 通过对上、下沙溪庙组岩石类型、结构特征、重 矿物组合、测井相结合地震相等分析手段,确定物源通道位于研究区的东北部,上、下沙溪庙组均以三角 洲前缘沉积为主,划分出三角洲前缘水下分流河道及水下分流间湾微相,有利沉积相带为水下分流河道 沉积。 此次研究,也为该区下一步沙溪庙组的油气勘探提供了基础地质资料。

Abstract

The Shaximiao Formation in Hexingchang-Fenggu area at the middle part of western Sichuan Depression attained a high degree of attention because of its large scale delta deposition and large exploration potential, but the sediment source and facies is unclear. The rock types and structural features, heavy mineral assemblage, well logging and seismic facies of Shaximiao Formation were analyzed. The result shows that the sedimentary source of Shaximiao Formation is located at the northeast of the study area. Subaqueous distributary channel and interdistributary bay are the dominant sedimentary microfacies, and subaqueous distributary channel is the favorable sedimentary facies. The research results provide basic geologic data for the oil and gas exploration in this area.
