The experimental analysis of 21 crude oil samples shows a good correlation between high molecular-weight hydrocarbon components (C 40+) and ***-four remaining oil samples extracted from oil sands of oilfield development coring wells were analyzed by high-temperature gas chromatography (HTGC),for the relative abundance of C 21-,C 21-C 40 and C 40+ *** relationship between viscosity of crude oil and C 40+ (%) hydrocarbons abundance is used to expect the viscosity of remaining *** mobility characteristics of remaining oil,the properties of remaining oil,and the next displacement methods in reservoirs either water-flooded or polymer-flooded are studied with rock permeability,oil saturation of coring wells,*** experimental results show that the hydrocarbons composition,viscosity,and mobility of remaining oil from both polymer-flooding and water-flooding reservoirs are heterogeneous,especially the *** abundance of C 21- and C 21-C 40 hydrocarbons in polymer-flooding reservoirs is lower than that of water-flooding,but with more abundance of C 40+ *** is then suggested that polymer flooding must have driven more C 40- hydrocarbons out of reservoir,which resulted in relatively enriched C 40+,more viscous oils,and poorer *** oil in water-flooding reservoirs is dominated by moderate viscosity oil with some low viscosity oil,while polymer-flooding mainly contained moderate viscosity oil with some high viscosity *** each oilfield and reservoir,displacement methods of remaining oil,viscosity,and concentration by polymer-solution can be adjusted by current viscosity of remaining oil and mobility ratio in a favorable range.A new basis and methods are suggested for the further development and enhanced oil recovery of remaining oil.

Rare earth elements,δS,Sr/Sr andδO were determined,and fluid inclusions were analyzed of fracture filling barite,anhydrite,fluorite,calcite and quartz from Upper Ordovician carbonates in Central tarim,*** aim was to assess the origin,evolution and flow of fluid in the *** was mixing of relatively hot Ba-rich and Sr-rich fluid with in situ basinal water and fresh water which was relatively cool and more radiogenic. The hotter fluid is hydrothermal as indicated by homogenization temperatures(HTs) about 20℃higher than the formation,and was most likely derived from Precambrian to Lower Cambrian clastic rocks or/and from the basement through *** is because almost all of Sr/Sr ratios of late stage fracture-fillings(mainly 0.70889-0.7103.) and present brines are higher than that of Upper Ordovician *** hydrothermal fluid was enriched in F,Eu,Ba,Sr and Zn during migration as indicated by the positive relationships of Eu to Sr,Ba and *** the hydrothermal fluid mixed with local basinal water,it precipitated isotopically-normal S anhydrite,fluorite and calcite with positive Eu *** precipitation of these Ca-minerals was followed by thermochemical SO reduction(TSR) of dissolved sulphates by *** was likely that only part of the SO was reduced and the generated HS leaked out,thus barite deposited from residual SO has abnormally highδS values from 42‰to 47‰and the generated HS is isotopically light from 15‰to 18‰.Subsequently,hydrothermal fluid was likely to have mixed with relatively cool and more Sr-rich freshwater,resulting in precipitation of quartz and fluorite with salinities as low as 0.5 wt%NaCl *** Sr/Sr ratios up to 0.7103..

Previously,troughs in continental faulted depressions were usually considered as a zone of hydrocarbon generation and expulsion rather than a zone for hydrocarbon *** they were confirmed to be the source kitchen,the possibility that they could constitute potential plays would be overlooked in the subsequent exploration *** on the hydrocarbon exploration practice of the Jizhong Depression and the Erlian Basin in the past several years,this paper discusses a new understanding that reservoir distribution is controlled by multiple factors and lithological accumulations are more likely to form in trough *** further documents the three main factors controlling the formation of large lithological hydrocarbon accumulations in trough *** paper also discusses the new concept that structural and lithological accumulations not only co-exist but also complement each *** propose that fan-delta fronts on inverted steep slopes in troughs,delta fronts and sublacustrine fans on gentle slopes,channel sands along toes of fault scarps are favorable locations for discovery of new oil *** application of this concept has led to the discovery of several hundreds of million tonnes of oil in place in trough areas in the Jizhong Depression and the Erlian Basin.

油气成藏体系是地表以下含油气的自然系统,它包括了形成油气藏的一切必要元素以及这些元素之间有效的配置结构,其中的元素是烃源岩、输导体系和圈闭。塔中早古生代和晚古生代成藏体系的烃源岩、输导体系和圈闭均为分离状,都属于三位成藏体系,但前者的油气来源单一(单源),后者的油气来源多样(多源),故两者分别被称之为塔中早古生代单源三位成藏体系和塔中晚古生代多源三位成藏体系。烃类流体主要来源于塔中北斜坡烃源岩,烃类流体沿不整合面和志留系砂岩层侧向运移,再沿断裂向上运移,分别为早古生代和晚古生代成藏体系提供油气。
