摘要
川西南龙王庙组气藏主要为构造背景下的岩性气藏,经历了早期古油藏发育、晚期裂解及后期调整等多个成藏期次,现今主要发育构造—岩性气藏。结合实钻分析认为:川西南地区溶蚀孔隙型储层分布、油气侧向封堵条件是龙王庙组成藏主控因素;井研—威远、资阳西北部是寻找构造—岩性气藏的突破目标区。
The gas reservoirs of the Longwangmiao Formation in southwest Sichuan are structural-lithologic gas reservoirs.The study indicates that main controlling factors of the hydrocarbon accumulation in the Longwangmiao Formation are dissolution-porosity reservoir distribution and oil and gas lateral sealing conditions.Jingyan-Weiyuan and northwest Ziyang regions are 2 targets searching for structural-lithologic gas reservoir.
