页岩气储层测井解释模型建立与评价方法研究

The Model Establishment and Evaluation Methods of Shale Gas Reservoir Well Logging Interpretation

针对EROMANGA盆地北东缘白垩系Toolebuc页岩储层特征,从测井岩心刻度出发,利用测井数据与实验结果回归方法,建立页岩的主要矿物含量以及总孔隙度、含烃饱和度、渗透率、总含气量等测井解释模型,建立一套适合于该地区的页岩气储层综合解释评价方法,用此方法对Toobeluc页岩储层进行精细解释,具有较好的应用效果。

According to the characteristics of Cretaceous shale Toolebuc reservoir in the north eastern margin of EROMANGA basin, the core of well logging was determined, and the shale contents of main minerals and total porosity were established using logging data and experimental results regression method. A set of logging interpretation models of hydrocarbon saturation, permeability and the total content of gas were established, comprehensive interpretation and evaluation method for the area of shale gas reservoir layer were also built. The method can provide refined interpretation for shale reservoirs of Toobeluc and has a good application effect.
