遂宁组

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir , while dissolution and fracturing can play a constructive role in that .

该大型岩性气藏的发现，说明川西地区浅层气仍然具有大的勘探前景，遂宁组气藏将是浅层扩展评价勘探和风险勘探的重要目标。

The Suining Formation gas pools will ( serve as ) the key target of extended assessment and risk exploration of the shallow gas in the study area .

影响现今遂宁组砂岩储层孔隙结构特征的因素主要是中等强度的压实作用、胶结物的充填作用以及破裂和溶蚀作用。

The main influences on the characteristics of the porosity texture of the Suining Formation Reservoir are : one is the medium intensity compaction and agglutinates fills actions , the other is abruption and corrosion .

根据统计学中累积贡献率大于80%确定公共因子的原则，确定降雨量与降雨历时为遂宁组紫色土地区侵蚀产沙量的公共因子。

According to the principle that accumulating contribution rate is more than 80 % in statistics , the rainfall and rainfall duration is the public factor for erosion sediment yield in Suining group purple soil .
