摘要
在岩心分析的基础上,分析和提取塔中"东河砂岩"储层的11个主要敏感性参数,同时利用常规测井方法可获得的岩石骨架、泥质含量、粘土矿物和物性参数等敏感性参数,然后在油田储层敏感性流动实验资料的基础上,运用逐步回归方法建立储层敏感性与测井资料的解释模型,对实际井进行处理分析。结果表明,由测井解释得到的储层敏感性结论与研究区的敏感性流动实验基本一致。
The Donghe sandstones are believed to be the major hydrocarbon reservoirs in central Tarim Basin, Xinjiang. Eleven parameters are selected to evaluate the reservoir sensitivity, including quartz, feldspar, lithic fragments, chlorite, illite, mixed illitemontmorillonite beds, ferroan dolomite, ferroan calcite, calcite, porosity and permeability. The model has been constructed for the interpretation of the reservoir sensitivity and well logs of the Donghe samdstones by using the successive regression analysis. The results in this study show that the method is workable for the prediction of the reservoir sensitivity of other exploratory wells in the light of well logs.
