摘要: 东濮凹陷是一个典型的盐湖沉积盆地,特殊的沉积特征决定了其油气资源评价方法的特殊性.根据东濮凹陷生油岩的高温、高压模拟试验资料,在一定的温压条件下,生油岩的液态窗可能会延长,使深部地层的油气资源,尤其是液态石油的资源供给量增加.模拟试验资料还表明,在高温、高压条件下,生油岩的总生烃量会增加,其有机碳的转化率最高可达41%.因此,用常规方法计算的资源量偏低,应重新测试在高温、高压条件下生油岩的产烃资源,准确计算东濮凹陷的资源量,为深层油气勘探明确目标.

Abstract: Dongpu Depression is a typical salty sedimentary basin.The special sedimentary characteristics require a special method for evaluating oil and gas resources.The modeling data of the source rocks at high temperature and high pressure show that the generation window of oil and gas can be prolonged under certain temperature and pressure,which results in the increase in amount of oil and gas resource,especially in the oil supply increment.The experiments showed that the total amount of hydrocarbon generation increased,and the highest transforming rate of organic carbon reached to 41 percent under the conditions of high temperature and high pressure.The conventional method to evaluate the hydrocarbon resources of Dongpu Depression may be underestimated.The thermal simulation at high temperature and high pressure can accurately evaluate the oil and gas reserves of the source rocks in Dongpu Depression,which benefits to determination of the exploration targets.

Key words: Dongpu Depression, salty sedimentary basin, source rock, oil and gas resource, evaluation model
