【摘要】 油气包裹体已成为油气成藏研究的有力工具,在划分油气运移充注期次、确定油气藏的形成时间、反映油气的成熟度及来源等方面均有重要的应用价值。近年来,利用油气包裹体及其共生的盐水溶液包裹体估算油气藏形成时的pVT条件是油气包裹体研究中的一个新热点,它为更准确地计算油气藏形成的温度-压力条件提供了一种独立的、更准确的技术手段。研究表明,包裹体岩相学和流体体系的热力学研究仍将是今后的发展重点。油气包裹体的pVT模拟技术尚处于初始阶段,两种软件(VTFlinc和FIT)的准确性和精确性虽有待进一步提高,但已经成为今后一个重要的发展方向。更多还原

【Abstract】 The study of petroleum inclusions,which has been made great progress in last 20 years,has played very important role in the evaluation of potential petroleum system.Because of its unique feature,it has become an effective tool for determining the oil migration and accumulation histories,the formation time of the oil reservoirs and the source and maturity of oil.The most significant progress recently in petroleum inclusion research field is pVT modeling,which could estimate the trapping p-T conditions of petroleum by using isochors intersection of coeval petroleum inclusions and aqueous inclusions.This technique could provide an independent and more accurate way for appraising the formation environment(trapping pressure and temperature) and compositional evolution history of petroleum system.Although the pVT modeling is still in its early stage as the present precision and accuracy of two kinds of software(VTFlinc and FIT) needs to be improved,it will be more and more applied to the quantitative analysis of petroleum reservoir formation by combining with traditional fluid-inclusion petrography and thermodynamic study.更多还原
