摘要
针对油气区远景资源潜力评价中缺乏定量依据的问题,提出了一种评价油气远景资源潜力的新概念———成藏门限,论述了油气成藏门限的地质含义及地质证据,并应用基于成藏门限理论开发的“油气成藏体系定量评价系统”对吐哈盆地前侏罗系油气资源潜力进行了定量评价,计算其油、气远景资源潜力分别为3.354×108t和2652×108m3,原油资源探明率仅为15%,表明吐哈盆地前侏罗系仍具较大勘探潜力。
One of the key tasks of petroleum explorationist is to evaluate resource potential of various petroliferous basins. The Pre-Jurassic Formations in Turpan-Hami basin, located in Xinjiang province in the northwest of China, have been explored for several years, but its quantitative resource potential is still unclear. A new concept for petroleum resource potential assessment that is called hydrocarbon pool-forming threshold has been proposed. It refers to the least hydrocarbon amounts dissipated during the process of pool formation in petroliferous basin. The existence of hydrocarbon pool-forming threshold has been proved by statistical analysis, physical and numerical simulation and geological phenomena. Due to the relative magnitude of hydrocarbon generation amount and its potential dissipation amount, different basins have different oil and gas resource potential. Only the basins that had entered the pool-forming threshold have exploration potential. By utilizing the new theory, the oil and gas resources of the Pre Jurassic formations in Turpan Hami basin have been calculated to be 3. 354× 10^8 tons and 2 652×10^8 m^3 respectively.The proved ratio of oil is only 15%, which indicates the great potential of Turpan-Hami basin for further exploration.
