摘要(Abstract)：

在露头和岩心资料不足、地震资料分辨率有限时,可利用测井资料识别层序地层界面。以高分辨率层序地层学理论为指导,详细分析鄂尔多斯盆地榆林气田山西组2段53口井的9条常规测井曲线特征,选择了4种测井曲线识别方案(声波时差对数法、电阻率曲线倒数法、自然电位和电阻率曲线组合法、自然电位镜像法)。通过探讨利用这四种方案识别鄂尔多斯盆地榆林气田山西组2段短期层序界面的方法,很好地解决了因岩心、地震资料不足导致识别层序界面难的问题,为充分利用测井资料识别陆相层序界面提供了新途径。
Logging data could be apply to identify sequence strata interfaces in case of being short of outcrop or core data and being limited by the resolution of seismic data.The theory proposed in this article is under the guidance of high resolution sequence stratigraphy,which after clearly deciphering the features of 9 regular logging curves for 53 wells in Shanxi Formation,Member II of Yulin Gas Pool of Ordos Basin,chooses 4 logging curve identification plans(acoustictime logarithm method,resistivity curve reciprocal method,spontaneous potential curve and resistivity curve combination method and spontaneous potential curve mirror method).How to use the 4 method to identify short-period sequence strata interface in Shanxi Formation,Member II of Yulin Gas Pool of Ordos Basin is discussed in detail.The methods could not only solve the problems of unavailable core and seismic data,but also give light to a new way of identifying continental sequence strata interface with logging curves.
