Abstract:

A mount of oil and gas reserves has been found in litho-stratigraphic play following the further exploration.Accurate division and objective assessment of oil and gas resources in litho-stratigraphic plays are important for selection of favorable districts.The effective reservoir predication method is suitable for resource assessment of litho-stratigraphic play.The main step of the method is to calculate the amount of oil and gas resources in litho-stratigraphic play by accurately determining the distribution of effective reservoirs and the abundance of oil and gas resources in the potential sandstone.The lower limit standard of effective reservoirs and the abundance of oil and gas resources in potential sandstone can be obtained by comparing with the verified sand stone.The fundamental principles and the procedures of the assessment method were introduced.The reliability of evaluated result was discussed.

Key words: litho-stratigraphic play, oil and gas resource assessment, effective reservoir prediction method, oil and gas resource abundance, oil and gas

摘要：

随着油气勘探的不断深入,在岩性地层区带中发现的油气越来越多,准确划分和客观评价岩性地层区带的资源潜力对有效指导勘探选区具有重要意义.有效储层预测法是针对岩性地层区带进行油气资源预测的有效方法,其核心是通过准确确定有效储层的分布以及远景砂体的油气资源丰度来计算岩性地层区带的油气资源量,可以通过与已探明砂体的类比得到有效储层的下限标准以及远景砂体的油气资源丰度.系统地介绍了该方法的基本原理和评价流程,并对评价结果的可靠性进行了评述.
