玛东斜坡区下乌尔禾组气测解释新方法研究
|
摘要
玛东斜坡区下乌尔禾组试油层传统气测解释图板解释符合率较低,分析认为是由于未考虑气测基值影响及显示层前后的气测变化关系所致。以该区试油段录井资料为基础,通过方差分析筛选出对油气水层识别的4项录井敏感参数,分别是气测全烃净增量、烃组分C_3与C_1比值、钻揭显示段前后气测全烃基值比及烃湿度(Wh)与烃平衡(Bh)分离度,并以这4项敏感参数构建全新的气测含油性综合指标X和Y,建立了气测含油性综合指标X与Y解释图板和解释标准。新方法经现场5口井应用验证,解释评价效果较好,具有一定的推广应用价值。
The interpretation coincidence rate of the traditional gas logging interpretation chart for the production test layers of lower Urho formation in Madong slope area is low.The analysis shows that it is caused by not considering the influence of gas logging base value and gas logging change relation before and after the display layer.Based on mud logging data of production test section in this area,4 mud logging sensitive parameters for identifying oil,gas and water layers are screened out through the analysis of variance,they are total hydrocarbon net increment,the ratio of C_3 to C_1,the ratio of total hydrocarbon to base value before and after the display section and separation degree of hydrocarbon temperature(W_h)and hydrocarbon equilibrium(B_h).Based on these four sensitive parameters,two new gas logging oil-bearing aggregative indexes X and Y were constructed.The interpretation chart for oil-bearing aggregative indexes X and Y and interpretation standards were established.The new method has been proved to be effective and has certain value of popularization and application.
