摘要
不整合面是斜坡背景下油气侧向运移的重要通道。对塔里木盆地斜坡背景下石油在不整合面的运移过程进行了模拟实验。模拟结果表明 ,最终油相散失量达 7.81%～ 11.5 1% ,平均为 9.6 6 % ,总体上反映出渗透率越高散失量越大及含油率越高散失量越大的特点 ,散失量不受层间非均质或层内非均质的影响。据模拟实验结果估算了石油在运载层中的散失量 。
Unconformity surface is an important pathway for petroleum migration on the slope. The modeling experiment of oil migration along the unconformity surface in Tarim basin shows that the least amount of oil losing is 7.81～11.51 percent and the average amount is 9.66 percent. The higher the permeability is, the larger the oil\|losing amount is. The oil\|losing amount increases with oil\|bearing ratio and is not affected by interbed or innerbed inhomogeneous features. The oil\|losing amount on the pathway is calculated according to the results of modeling experiments. Oil and gas mainly migrate vertically along faults and laterally in short distance.
