四川盆地雷口坡组资源量大，除勘探早期发现卧龙河、磨溪雷一1气藏外，其余地方尚未在雷一段获得规模储量。随着川西地区海相层系勘探步伐的加快，特别是川西北地区勘探程度的深入，雷一1逐渐显示出良好的勘探前景。在川西北雷口坡组地层厘定的基础上，根据野外剖面、岩屑样品、钻井和试油等资料，认为川西北地区雷一1储层有着与川中磨溪、川东卧龙河相似或者相当的储集性能，均属于受滩相控制的储层。与此同时，该区经历了多期次的构造运动，构造圈闭、断层发育，有利于油气的运移和聚集，综合分析后认为，龙门山前缘中北段的中坝-双鱼石以及米仓山前缘的梅树铺-九龙山一带是最有利的勘探区带。

Leikoupo Formation has a large amount of resources,but in addition to the previously found Wolonghe,Moxi gas reservoir,no other reserve of scale has been found. With the progress of exploration of the marine strata in western Sichuan,es-pecially further degree of exploration,the T2l11 gradually exhibits its good exploration prospects. Based on Leikoupo Formation determination,and according the field profile,debris samples,oil drilling and test data analysis,we think that the sub-section of the T2l11 belongs to the reservoir controlled by shale facies which is similar or equivalent to Moxi and Wolonghe reservoirs. Structural traps and fault development in the area are conducive to oil and gas migration and accumulation. Comprehensive analysis reveals that the most favorable exploration zones are the Zhongba-Shuangyushi belt in the front north of Longmen mountain and the Meishupu-Jiulongshan belt in the front of Micangshan mountain.
