| 摘 要： | 通过对邻北构造石炭系已有钻井资料的综合研究，将石炭系地层划分为3个岩性段。利用已有的岩心孔隙度资料和测井资料以及测井解释软件对孔隙度进行定量解释的结果表明，南区的Ⅱ类储集岩的厚度和Ⅲ类储集岩平均孔隙度都比北区大，因此认为邻北构造南区储集性要比北区好。

| Abstract: | According to available drilling data of Carboniferous in Linbei structure, Carboniferous can be divided into 3 lithologic segments. The segment with developed pores is mainly distributed in dolomite in middle and upper parts of Huanglong. The pores of reservoirs are mostly secondary ones, and pore evolution is dominated by diagnesis. The evolution history can be divided into 3 periods. Based on existing core porosity data, logging data and logging interpretation software, the porosity is quantitatively interpreted. The interpretation results suggest, the thickness of the second order reservoirs and the average porosity of the third order reservoirs in southern part are higher than those in northern part, so, it is believed that the structural southern part in Linbei area is better than northern part in hydrocarbon accumulation. |
