摘　　要：基于岩心观察描述、取心段大量分析化验资料及测井数据,对蜀南地区黄家场-隆昌构造雷一^1段储层的岩石类型、储集空间类型及储层物性进行了综合分析研究,探讨了雷一^1储层发育的主要控制因素,并对该储层做出分类评价。研究结果表明,雷一^1段储层主要发育溶蚀孔、晶间孔及微裂缝;受泸州古隆起及沉积环境控制因素的影响,成岩作用中溶蚀作用及白云石化作用大大改善了储层物性,雷一^1储层为大中孔-中低渗型储层;根据工区储层分类评价标准,雷一^1段主要发育Ⅱ、Ⅲ类储层,且主要分布在靠近古隆起的局部构造高部位海拔（900～1 300m）平缓斜坡地带。Based on core observation,analytical data from coring interval and log data,the comprehensive studies covering reservoir rock types,reservoir space types and reservoir properties of Lei-1 segment of Huangjiachang-Longchang structure in southern Sichuan province and the main controlling factors of reservoir development have been carried out and discussed.The reservoir classification and evaluation have been made.The results show reservoir of Lei-1 segment is mainly developed with dissolution holes,intergranular pore and micro-cracks.Affected by dissolution and dolomitization in the diagenesis,the reservoir properties were greatly improved.Reservoir of Lei-1 segment is of bigmiddle porosity and middle-low permeability.According to reservoir classification evaluation criteria in the area,Lei-1segment is mainly developed withⅡandⅢtypes reservoirs,and mainly distributed in the gentle slope zone,with structural high position of 900~1300m altitude and close to the ancient high uplift.
