摘　　要：江汉盆地江陵凹陷油气资源丰富,新沟嘴组下段1油组、2油组是其主要目的层,不同的沉积构造背景,气测烃组分不同,现有的气测解释方法适用率较低。为了提高江陵凹陷新沟嘴组下段油水层气测解释精度,通过对研究区已试油的14口探井的气测资料和试油资料分析统计,结合区域地质条件综合研究,发现全烃含量-湿度比值法对工区目的层油水层判断符合率高,地质应用效果较好,有较高的成果转化转移价值。Jiangling depression in Jianghan basin is abundant in oil and gas resources,and the pay zone No.1 and No.2 in the lower member of Xingouzui Formation are the main target strata;owing to different hydrocarbon components of gas shows in different sedimentary tectonic setting,the existing gas logging interpretation method is less applicable.In order to improve the interpretation accuracy of the oil—water layer in the lower member of Xingouzui Formation in Jiangling depression,through the analysis and statistics of the gas logging data and oil test data of 14 exploration wells which have been tested in the study area,it is found combined with the comprehensive study of regional geological conditions that the method for the ratio of total hydrocarbon content to humidity can be used to identify the higher coincidence rate of the oil—water layer of the target zone with good geological application effect and the higher transformation value of achievements.
