摘要
从鄂尔多斯盆地B区块上古生界致密砂岩气储层的测井响应特征出发,研究了测井参数与储层产能的关系。通过分析岩性、物性、电性测井资料,提取了储层产能测井敏感参数,建立了储层分类标准。以物性参数为主建立产能预测模型,在此基础上,考虑岩石脆性对储层压裂后产能所造成的影响。将岩石脆性因子引入到产能预测模型中,修正了原有模型,提高了预测精度。实际测试结果表明该方法效果明显,在B区块的新井生产、测试中有一定的指导意义。
Based on logging response characteristics of the tight sandstone gas reservoir of Upper Paleozoic in B block, Ordos basin, the relationship between logging parameters and reservoir productivity is studied. After analyzing the lithology, physical property and electrical logging data, reservoir productivity logging sensitive parameters are extracted and reservoir classification standard is established. Also established is productivity evaluation model mainly based on physical parameters while considering the impact of rock brittleness on reservoir productivity after fracturing. The rock brittleness factor is introduced into the productivity evaluation model, the correction of the original model improves the prediction accuracy. The test results show that the effect of this method is obvious, and there is certain significance in the production and test of new wells in B block.
