针对我国中、新生代陆相已开发油藏特点,选择非均质性严重的注水开发河流相砂岩油藏作为研究对象,结合胜利油区主力油田孤东油田七区西馆陶组的实例,着重油藏地质精细研究,采用动静态相结合的方法,研究特高含水期剩余油分布的预测方法,准确确定剩余油的相对富集部位。分布规律及控制因素,为高含水后期油田调整开发方案。制定挖潜增产措施、控水稳油。提高采收率提供科学依据。该论文取得以下主要研究成果:1。以油藏地质精细研究为基础,形成了利用开发地质学、水淹层测井评价、生产动态分析、油藏数值模拟及油藏工程等多种方法对剩余油进行综合预测的方法和技术,其中流动单元约束下的测井评价和油藏数值模拟技术是综合预测剩余油分布的新的方法和技术。2。在纵向上从层间至层内,对储层开展多层次逐级细分研究,精细至流体流动单元,为细致地揭示平面上,垂向上层间及层内剩余油的不均一分布创造了条件。3。引人流体流动单元新概念,提出了非均质综合指数法和岩性单元流动分层指标法识别流体流动单元的新方法,通过流动单元的识别和划分,揭示了油藏非均质性,开展了从流动单元角度进行剩余油的预测方法与富集规律研究。4。在理论上阐明特高含水期河流相储层剩余油形成机理、分布规律和控制因素,提出特高含水期强非均质性河流相砂岩油藏,剩余油储量主要富集在主力相带边滩微相的新观点和新认识,改变了以往剩余油主要富集在非主力相带的观点和认识。5、研究得到的剩余油富集规律新观点和新认识,在实际应用中得到验证,取得了显著的经济效益和社会效益。

Reversed-phase high-performance liquid chromatographic (RP-HPLC) retention parameters, which are determined by the intermolecular interactions in retention process, can be considered as the chemical molecular descriptors in linear free energy relationships (LFERs). On the basis of the characterization and comparison of octadecyl-bonded silica gel (ODS), cyano-bonded silica gel (CN), and phenyl-bonded silica gel (Ph) columns with linear solvation energy relationships (LSERs), a new multiple linear regression model using RP-HPLC retention parameters on ODS and CN columns as variables for estimation of soil adsorption coefficients was developed. It was tested on a set of reference substances from various chemical classes. The results showed that the multicolumn method was more promising than a single-column method was for the estimation of soil adsorption coefficients. The accuracy of the suggested model is identical with that of LSERs.
