应用区块品位综合评价辽河油区未开发储量

Comprehensive assessment of block grade of undeveloped reserves in Liaohe oil province

针对辽河油区未开发储量零散,静、动态资料不全,储量丰度低、含油饱和度低、储层物性差、油藏埋藏深、油井产能低等问题,运用区块品位综合评价法,确定权衡区块品位的评价因子,并用比较法确定各因子权重,最终确定未开发储量品位并排序,优选品位较高区块作为下步开发的重点,指导辽河油区未动用储量的有效和有序开发。

Undeveloped reserves in Liaohe oil province are characterized by scattering, low abundance, low oil saturation, poor petrophysical property, deeply buried and low productivity, and both static and dynamic data are incomplete. This paper uses comprehensive assessment method of block grade to determine the appraisal factors, and uses comparison method to determine the weight of each factor, and finally determine the grade and order of undeveloped reserves. Blocks with higher grade are selected as next development blocks, thus guiding effective and ordered development of undeveloped reserves in Liaohe oil province.
