摘要
在分析了目前国内外常用的７种气测评价方法后指出，气体评价法、轻烃比值法、双对数比值法３种气测解释方法在准噶尔盆地适用性较强，解释符合率较高。在选择气测解释方法时，一定要考虑本地区的储层流体特征及钻井条件，并利用随钻资料对解释方法的区带区间值进行必要的修正；在进行气测解释时应充分利用各种解释方法之间的互补性，综合分析、取长补短，以提高解释精度。
Based on analysis of seven commonly used gas logging evaluation methods at home and abroad,this paper pointed out that three gas logging interpretation methods(gas logging evaluation,light hydrocarbon ratio and dual logarithm ratio methods) were comparatively applicable in Junggar basin,and obtained the results matching well with the fact.When choosing gas logging interpretation method,reservoir fluid characteristics and drilling conditions must be considered,and essential correction on zonal or interval values should be made with the data while drilling.Meanwhile,gas logging interpretation should rely upon the mutual compensation of precision of each method in order to improve the precision of interpretation.
