摘要
为了准确评价页岩气储层的产气性,基于涪陵页岩气产气测试资料分析,优选出影响页岩气储层产气性的关键参数,将其分为页岩气产气影响因子GPF和储层评价指数LEI两类,建立了以评价参数赋分标准为约束条件的页岩气储层GPF-LEI产气性评价方法。涪陵页岩气田的应用结果表明:页岩气储层产气性评价类别越好,测试的无阻流量越高;利用该方法预测的页岩气储层无阻流量与实际测试结果基本吻合,相对误差为15.5%。研究表明,利用该方法评价的页岩气储层产气性类别与无阻流量具有较好的相关性,为评价页岩气储层产气性提供了一种新方法。
In order to accurately evaluate the gas production property of shale gas reservoirs,the key parameters affecting the gas production in shale gas reservoir were selected based on the analysis of the gas production test data of the Fuling Shale Gas Field,and further divided into both the shale gas production factor GPF and the reservoir evaluation index LEI.They formed the basis by which the GPF-LEI gas production property evaluation method for shale gas reservoir was established by taking the evaluation parameter scoring standard as the constraint condition.The site verification in the Fuling Shale Gas Field showed that the better the kind of gas production evaluation category,the higher the open flow capacity.The open flow capacity of shale gas reservoir predicted by this method basically matches with actual test results,and the relative error is 15.5%.Research results indicated that the gas production category of shale gas reservoir evaluated by this method had a good correlation with open flow capacity,and provided a new method for evaluating the gas production property in shale gas reservoirs.
