摘　　要：WL油田存在的特殊油层有正常油层的有效孔隙度和渗透率 ,但声波时差值异常的低 ,因而很容易被解释成致密干层。根据所收集的大量资料 ,建立了以微电极测井曲线为主 ,结合其它测井参数的方法 ,能够有效地识别特殊油层 ,提高测井解释符合率。There is a special kind of oil reservoir in WL Oilfield, whose effective porosity and permeability is within the range of normal oil reservoir, but its acoustic interval travel time is very low. So the oil reservoir is liable to be interpreted as tight dry zone. Based on a vast amount of information, a method is established which mainly depends on minilog curves combining with other log parameters. It can effectively distinguish special oil reservoir from dry sand, improving the conicidence rate of interpretation with well testing result.
