Focusing on the relationship between the characteristics of argillite and petroleum migration, the authors have studied and discussed the regularity between argillite compaction and the primary migration of oil/gas within the basin, on the basis of the data of a-coustic time and fluid pressure. It is suggested that low pressure zones or hydrostatic pressured zones are the orientation prefered by petroleum migration and accumulation, and therein the areas of petroleum enrichment.

Focusing on the relationship between the characteristics of argillite and petroleum migration, the authors have studied and discussed the regularity between argillite compaction and the primary migration of oil/gas within the basin, on the basis of the data of a-coustic time and fluid pressure. It is suggested that low pressure zones or hydrostatic pressured zones are the orientation prefered by petroleum migration and accumulation, and therein the areas of petroleum enrichment. Pressure seals formed in the abnormal high-pressured zones are considered as important factors for the formation of gas pools while the release and disappearance of the pressure in the abnormal high pressured zone during argillite compaction and expansion caused by hydrocarbon generation are the driving forces for the primary migration.

本文从泥岩压实演化特征与油气运移的关系入手,依据声波时差以及流体压力资料,剖析和探讨本区泥岩压实演化与油气初次运移的规律,指出低压过剩区带或静水压力区带是油气运移聚集的方向和富集区,异常高压带所形成的压力封闭是本区天然气藏形成的重要条件,而异常高压带在泥岩压实过程中释放和消失以及烃类生成作用的膨胀力,则是油气初次运移聚集的动力。

Explorations in marine strata (mainly in the Paleozoic strata) have been conducted for many years in China. Comparing with the expecting results, we have a long way to go in the exploration. The major reasons, for that , the authors believe, are most Chinese petroleum geologists being lack of clear understanding of petroleum enrichment and distribution patterns in marine facies of China. There are some big differences between China's marine basins and the petroleum rich marine basins in the other part of the world: Old age, low organic abundance, high thermal evolution, deep burial of target stratum and the poorly preserved condition of the pools are the characteristics of the marine facies strata in China. To achieve a good exploration results, multi discipline researches on three basic theoretical problems must be conducted in an new angle. The problems include: ①Basin forming theory which is related to the researches of earth dynamics, basin deposition and buildup types, stratum styles and diagenetic events. ②Hydrocarbon forming theory including studies on paleontology, palaeo oceanography, palaeo environmental chemistry, sedimentology, organic lithology, organic geochemistry and physical chemistry. The researches should not be fettered by the classic kerogen thermal degradation theory, and only in this way could some new concepts of hydrocarbon forming theory, which are suited to Paleozoic marine basin in China, be put forward. ③Pool forming theory which should reveal the problem of petroleum migration in carbonate dominated geological body, establishing the physico chemistry field pattern in pool forming process of oil and gas charging and pouring, and forming petroleum adjusting pattern in dynamic equilibrium view.

中国覆盖区海相地层(以古生界为主)勘探多年,勘探发现与预期结果差距甚大,认为主要原因是我国石油地质家对海相油气富集及分布规律的认识甚少。我国海相盆地与国外富油气海相盆地差异显著:①时代老;②有机质丰度低;③有机质热演化程度高;④勘探目的层埋藏深;⑤油气藏保存条件差。必须开展多学科联合研究,从新的角度加快研究3个基础理论问题:①成盆理论,要进行地球动力学和盆地沉积建造类型、地层样式及地层成岩事件研究;②成烃理论,要进行古生物学、古海洋学、古环境化学、沉积学、有机岩石学、有机地球化学和物理化学研究,研究不能受干酪根热降解成烃学说的束缚,有可能提出更适于我国古生代海相盆地的新成烃理论;③成藏理论,要揭示以碳酸盐岩为主的地质体中的油气运移问题,建立油气充注成藏过程的物理化学场模型,并以动态平衡观点建立油气藏调整模型。(王孝陵摘)

There are two different hydrodynamic systems which are independent and of interaction in oilfield waters. They are"depositional artesian water dynamic system"and"surface infiltration water dynamic system",which play an important role in controlling the migration, accumulation and preservation of hydrocarbon in basins,and in controlling the generation and distribution of oil and gas pools. Oil-gas accumulation mainly takes place in retarding and stagnating alternation area of hydrogeologic zone;the low-value...

There are two different hydrodynamic systems which are independent and of interaction in oilfield waters. They are"depositional artesian water dynamic system"and"surface infiltration water dynamic system",which play an important role in controlling the migration, accumulation and preservation of hydrocarbon in basins,and in controlling the generation and distribution of oil and gas pools. Oil-gas accumulation mainly takes place in retarding and stagnating alternation area of hydrogeologic zone;the low-value area of sedimentation alternation strength is an accumulation area of petroleum;centrifugal flow of sedimentary water causes petroleum in a depression to be distributed in bands around the center of the depression; hydrodynamic anomaly within threshold of oil generation provides equipotential energy space for the formation of oil and gas pools; ancient hydrodynamic balance in local places controls petroleum enrichment;and infiltration of surface water can do good or harm to petroleum preservation.

油田水中存在“沉积承压水”和“地表渗入水”两个相对独立而又相互作用的水动力系统,前者由上覆地层重量所引起的地静压力以及地静压力等引起的异常孔隙流体压力所形成,具有内循环承压式水交替特征,后者为大气降水和地表水向储集层的渗入而形成,以外循环渗入或水交替为特征。这两大系统(尤其是前者)的作用在很大程度上控制了含油气盆地中油气的运移、聚集和保存,油气聚集区主要位于水文地质带中的交管阻滞一停滞带内,沉积交替强度的低值区是油气富集区,沉积水的离心流使凹陷中的油气围绕凹陷中心呈带状分布。
