基于测井资料定量表征页岩储层非均质性
|
摘要
为了解决页岩储层非均质性影响因素多以及难以综合定量表征页岩储层非均质性的问题,基于洛伦兹曲线理论计算页岩宏观非均质性的总有机碳含量、微观非均质性的矿物组分和有效孔隙度以及岩石力学参数非均质性的杨氏模量和泊松比等影响因素的洛伦兹系数,结合运用层次分析法确定影响因素权重,建立综合定量表征页岩储层非均质性方法。研究表明:该方法表征结果与预测布缝方式和压裂施工曲线吻合较好。该方法为页岩储层非均质性表征提供了一种思路,同时对威远地区压前预测和压后评价具有一定参考价值。
In order to effectively select influencing factors of shale reservoir heterogeneity and solve the problem of comprehensively quantitatively characterizing shale reservoir heterogeneity,the Lorentz coefficient of total organic carbon content of macro heterogeneity,effective porosity and mineral content of micro heterogeneity,the Young's modulus and Poisson's ratio of rock mechanics parameters heterogeneity on shale reservoir heterogeneity were calculated according to the Lorentz theory,the weights of which were determinedby using analytic hierarchy process.And then,a quantitative characterization method of shale reservoir heterogeneity was established. Finally,a horizontal well was quantitatively characterized by using the new method,which was located in the Weiyuan Area,Sichuan Basin,China. It is shown that the quantitative characterization results of 13 stages fracturing sections are mostly in good agreement with the prediction of setting fractures modes and analysis results of fracturing curves.Meanwhile,it can be seen that the quantitative characterization method can provide a new idea for the evaluation of the heterogeneity of shale reservoirs,which has certain reference value for pre-frac prediction and post-frac evaluation in Weiyuan area.
