摘要
在干酪根类型数值比和恢复原始有机质丰度的基础上建立了一种生油岩生油量和排油量的计算模式 Q生=DR∫_s∫C_1(x,y)H(x,y)dxdy O运=DR∫_s∫C_2(x,y)H(x,y)dxdy 该模式综合考虑了有机质的丰度、类型和成熟度及它们在平面上的变化,采用二重积分形式而不是取有关变量的观测值的算术均值参加计算,可能有助丁提高计算精度.模式在松辽盆地北部西区青二、三段生油岩生、排油量计算中的应用效果比较理想。
Based on the digitalization of kerogen type and the recovery of original organic richness, a model of calculating the amount of petroleum generated and migrated is constructed as follows: Q_(generation) = D·R∫ ∫C_1 (x, y)·H (x, y)·dx·dy Q_(migration) = D·R∫ ∫C_2 (x,y)·H (x, y) dx·dy The richness, type and maturation level of organic matters as well as their lateral variations have been taken into account comprehensively in the model. Double integral rather than arithmetic mean value of elevant parameters is used in the calculation which is possible to improve the accuracy of calculation.
