摘要:
利用砂巖骨架礦物和黏土礦物在中子測井響應上存在較大差異的特性,結合體積模型,提出重構含水純砂巖中子曲線進行泥質砂巖和含礫砂巖儲層物性評價的新方法。以渤海油田石臼坨凸起某區塊中、粗粒巖屑長石砂巖和含礫砂巖儲層為例,結合巖心、測試等資料,采用該方法可以較好地指示儲層巖性及物性的變化;利用該方法劃分了巖相,確定了優勢儲層,并分巖相計算了滲透率,使其精度得到了明顯提高。將重構中子曲線與實測中子及密度曲線組合,建立了指示儲層物性的孔隙結構指數曲線,與測試產能具有良好的相關性,這為利用常規測井資料預測產能提供了新的思路。
Abstract:
In view of the larger differences in neutron logging responses of rock matrix from clay minerals and based on a Volumatic model, proposed for evaluating the physical properties of argillaceous and conglomeratic sandstone reservoirs by reconstructing the neutron log curve of water-bearing pure sandstone. Then, taking the medium and coarse-grained lithic feldspar sandstone and conglomerate sandstone reservoirs in a block of the Shijiutuo uplift in Bohai Oilfield as a case, the method was applied by considering core and well test data. The result proved that it could better indicate the changes of lithology and physical properties of reservoirs. In addition, the method was used to divide lithofacies, determine favorable reservoirs, and calculate lithofacies permeability, which accuracy was improved obviously. Finally by combining the reconstructed neutron log with measured neutron and density logs, a pore structure curve was established, which can indicate reservoir physical properties, and is well correlated to the tested productivity. It is a new method for predicting productivity by conventional log data.
