Significantly gas discovery is mode from the sandstone reservoirs of Penglaizhen formation (Upper Jurassic) with a burial depth of 1500 meters in western Sichuan depression. It's of great e-conomic value to the country. The petrography of Penglaizhen formation occurs as a red deposit iron-bearing sequence of shallow lacustrine and deltaic facies. The sandstone reservoirs have an average porosity of 15. 1% and permeability of 5. 7972 × 10-3μm2. The reservoir pore space has mainly been found as reduced intergranular pores and secondary dissolution pores. This paper focuses on the contribution and forming mechanism of secondary porosity. Two forming mechanisms are considered: the carbonate cement dissolution caused by organic acid resulting from redox reaction when hydrocarbon migrated up from underlying upper Triassic source rock and reacted with oxidants (Fe2O3) in the sandstones. Another is the meteoric water leaching during the uplifting ofYansan middle epoch. In addition, sedimentary facies, compaction and cementation are also responsible for primary porosity and reduction of intergranular pore-space of sandstones.

川西坳陷上侏罗统蓬莱镇组砂岩中产出了丰富的天然气,产层埋深在1500m以内,因而具有重要的经济价值。蓬莱镇组为滨浅湖一三角洲相红色砂泥岩序列,储层砂岩孔隙度平均15.1%,渗透率平均5.792×10~(-3)μm_2,储集空间以残余原生粒间孔及次生溶孔为主。着重研究了红色砂岩中的各种孔隙类型及其控制因素。统计结果表明原生孔和次生孔各占总孔隙度的50%土。次生孔隙的形成机制有两种:一是烃类从下伏上三叠统须家河组向上运移并与储层砂岩中的氧化剂(Fe_2O~3)发生氧化还原反应,反应产生的有机酸溶解碳酸盐胶结物导致次生孔隙的形成,另一则与燕山运动中幕地层抬升遭受剥蚀和大气淡水的淋滤有关。控制储集砂岩中孔隙发育的地质因素除上述机制形成的次生孔隙外,沉积相和压实、胶结等成岩作用决定了初始孔隙度以及砂岩粒间体积的减少。
