摘要

2014年,四川盆地双鱼石构造中二叠统栖霞组钻获高产工业气流以来,随着勘探开发工作的持续开展,已钻获多口高产工业气井,深入开展龙门山推覆构造带—山前带构造特征研究,是认识该区上古生界气藏特征、进一步向推覆构造带拓展油气勘探领域的重要前提。为此,基于新完钻的红星1井实钻成果、新解释的束线三维地震资料,解剖了龙门山逆冲推覆构造带—山前带的构造特征,进而分析了山前隐伏构造带的天然气成藏条件和勘探前景。结果表明：①龙门山推覆构造带发育一系列向盆内逆冲断裂,形成多套推覆体叠置,表现为多个断层传播褶皱叠加,推覆断裂下盘隐伏构造带,表现为挤压断褶构造;②二叠系推覆体及原地地层油气显示丰富,含气性好,隐伏构造带栖霞组发育台缘滩相白云岩,白云岩储层储集性能好;③隐伏构造带面积大,天然气成藏条件好,具有良好的勘探前景,是川西北部地区深层海相层系勘探拓展寻找规模新突破的重要有利区带。

Abstract

In 2014, commercial gas flow was obtained from the Middle Permian Qixia Formation of Shuangyushi structure in the Sichuan Basin. Several high-yield gas wells have been drilled through continuous exploration and development. The study on properties of the Longmenshan nappe-piedmont structural belt is valued as an essential prerequisite for understanding the characteristics of the Upper Paleozoic gas reservoirs in this area, and further extending the exploration to nappe belts. Therefore, based on the drilled Well Hongxing 1 and newly interpreted beamline 3D seismic data, the structural characteristics of the Longmenshan thrust nappe -piedmont belt were identified so as to analyze the gas accumulation and exploration prospects of the piedmont buried structural belt. The results show that, (1) a series of basinward thrust faults are developed in the nappe structural belt, forming superimposed multiple nappes which appear as multiple fault-propagation folds, and footwall buried structural belt of thrust fault which presents as a compressional fault-fold structure; (2) the Permian nappes and in-situ formations indicate good gas-bearing property with rich oil and gas shows; there develops marginal-platform shoal dolomites in the Qixia Formation of buried structural belt, which exhibit good reservoir performance; and (3) the buried structural belt, with large area and favorable conditions of gas accumulation, suggests promising exploration prospects, indicating a critical target for new exploration breakthroughs of deep marine strata in northwestern Sichuan Basin.

Key words： Longmenshan nappe structural belt; Buried structural belt; Structural characteristics; Reservoir characteristics; Gas accumulation condition; Exploration prospect
