摘要
西昌盆地是一个油气勘探新区 ,而七坝 1井则是西昌地区目前惟一的油气钻井。因此 ,对该井有关资料的研究对今后西昌地区的油气勘探具有重要价值。通过岩心观察、显微镜薄片鉴定和实验室测试分析 ,详细研究了该井古生界的岩石学、储集物性、测井和录井等特征 ,进而对古生界的储层特征进行了探讨。研究发现 ,七坝 1井下二叠统栖霞组发育多种类型的储集层 ;下志留统韩家店组和石牛栏组发育多段裂缝性储集层。由此认为 。
Xichang Basin is a new region for oil and gas exploration and the well Qiba 1 is the only well having been drilled for oil and gas in the basin at present. For this reason, the research on the relevant data on the well is of important value to the petroleum exploration in the region in the future. Through core description, thin-section identification and laboratory analysis, the characteristics of Paleozoic reservoirs are discussed in the paper on the basis of studying the data on the petrology, petrophysical properties and loggings of the Paleozoic in the well in detail. The research results indicate that there are many types of reservoirs in Qixia Formation of Lower Permian and multiple- interval fractured reservoirs in the Hanjiadian Formation and Shiniulan Formation of Lower Silurian in well Qiba 1.Therefore, it is considered that the Paleozoic should be the important target horizons for oil and gas exploration in Xichang Basin.
