摘要
四川盆地中三叠统雷口坡组雷一段储层,早印支期形成的泸州、开江两个古隆起及其东南雷一段储层残存甚少,勘探领域主要分布在盆地中部和北西边缘。目前,仅于川中遂宁发现一个较大的磨溪气田,其储集空间主要为连续而较稳定的溶蚀针孔白云岩和石灰岩。尽管该溶孔储集岩在泸州-开江两个古隆起北、西侧钻达的井尚少,但雷一段于武胜龙女寺、岳池罗渡溪、合川涞滩场、华蓥西、铜梁王家场、潼南以及荣昌河包场等构造和地区均有发现,并于罗渡溪构造钻获工业气流。因此,预测雷一段储层可能是一区域性较好的储层。
Lei No. 1 Member reservoir of Leikoupo Formation in Middle Triassic of Sichuan Basin is seldom remained on Luzhou and Kaijiang palaeohighs formed in Early Indo-Chinese epoch and to their south, so the exploration domain is mainly focused in the center, west and north margins of the basin. At present, only one much bigger gasfield-Moxi Gasfield is discovered in Suining-the center of Sichuan Province, its storage space is principally connected and much stable solved needle-hole dolomite and limestone. Although only a few wells penetrate this kind of reservoir in the north and west of the above two palaeohighs, Lei No. 1 Member is popularly discovered the follow structures and regions: Dragon Daughter Temple of Wusheng, Luodu Stream of Yue Pond, Laitanchang of Hechuan, West Huaying, Wangjiachang of Tongliang, Tongnan, Baochang of Rongcang River and on. At the same time, the commercial gas flow is obtained on Lodu Stream Structure. Therefore Lei No. 1 Member reservoir may be predicted to be much better regional reservoir.
