    • 摘要: Based on the latest seismic data,geological understanding and exploration results in the Southwestern Ordos Basin,paleo-deformation characteristics of the 1st member of the Upper Paleozoic were studied using tectonic evolution analysis and paleo-structure restoration,and controlling effects of paleo-structure on hydrocarbon distribution were ana-lyzed.According to the strata correlation,the sedimentary,deformation,and subsidence characteristics of the 1st member of the Permian Shanxi Formation are identified.The tectonic evolution and hydrocarbon accumulation stages revealed that the hey periods of the Upper Paleozoic tectono-hydrocarbon accumulation are the Late Jurassic and the end of the Early Cretaceous in the Southweste.Through the restoration of Shan 1 paleo-structure in different tectonic evolution stages,the ancient structure of the Upper Paleozoic Shan 1 in Late Triassic,Late Jurassic and end of Early Cretaceous share similari-ties but also demonstrate gradual evolution through time.The paleo-uplift and paleo-slope are widely developed in the late Jurassic,while the western slope gradually narrowed and the Tianhuan Depression is formed at the end of the Early Creta -ceous.Based on the analysis of tectonic deformation and hydrocarbon accumulation stages,it is believed that the Late Ju-rassic Shan 1 paleo-structure is the hey factor controlling the distribution of the Upper Paleozoic gas reservoirs in the Southwest Ordos basin.Due to the lach of long-distance migration of the gas in the Upper Paleozoic reservoirs in the study area,the Early Cretaceous hydrocarbon charge is focused around the Late Jurassic ancient structure highs of Shan 1 mem-ber.Thus the hydrocarbon accumulation model is characterized by near-source or intra-source accumulation.%基于鄂尔多斯盆地西南部最新地震、地质资料和勘探成果,通过构造演化史分析和古构造恢复等手段,重点研究了鄂尔多斯盆地西南部上古生界山西组1段古构造特征,并分析了古构造对油气分布的控制作用.通过地层对比分析,明确了二叠系山1段的沉积-构造-沉降特征.构造演化史和成藏期次揭示,西南部上古生界构造-成藏关键变革期为侏罗纪末期和早白垩世末期.通过对不同构造演化阶段山1段古构造的恢复,认为三叠纪末期、侏罗纪末期和早白垩世末期上古生界山1段古构造具有继承性和迁移性.其中古隆起和古斜坡在侏罗纪末期发育广泛,西倾斜坡范围呈逐渐收窄趋势,天环坳陷形成于早白垩世末期.在构造变形与成藏期次分析的基础上,认为侏罗纪末期山1古构造可能是控制鄂尔多斯盆地西南部上古生界气藏分布的关键因素.研究区上古生界天然气缺乏长距离运移的条件,早白垩世末期的油气充注围绕着侏罗纪末期山1段的古构造进行,表现为近源或源内成藏.

    • 摘要: 地温-地压系统(以下简称温压系统)控制油气的生成、运移和聚集,为明确文昌A凹陷温压系统特征及其与油气成藏的关系,基于地温和地压实测数据及声波测井等资料,利用温压系统原理,对珠江口盆地文昌A凹陷的地温场、地压场及温压系统特征进行剖析,从油气的生成、保存及分布角度探讨温压系统与油气成藏的关系.研究表明:文昌A凹陷地温梯度较高,平均为33.8 °C/km,有利于有机质的成熟与烃类的生成;泥岩欠压实段集中在珠海组、恩平组,强化了油气的封盖作用;珠江组泥岩不发育异常压力,以毛细管压力封闭为主;凹陷发育高压型复式温压系统,上、下2套温压系统的流体能量差较大,油气以垂向运聚为主,浅部静压型温压系统内部最利于油气富集成藏,恩平组含油气系统是最重要的勘探对象.该研究对珠江口盆地的勘探有一定的指导意义.%Geothermal-geopressure system (temperature-pressure system) may effectively control generation, migration and accumulation of hydrocarbons.To clarify specific features of the temperature-pressure system in Wenchang A Sag and its relationship with hydrocarbon accumulation, features of geothermal field, geopressure field and temperature-pressure system in Wenchang A Sag of the Pearl River Mouth Basin have been reviewed by using measured geothermal and geopressure data, together with acoustic logging and other data through principles related to the temperature-pressure system.In this way, correlation between temperature-pressure system and hydrocarbon accumulation can be clarified with regard to generation, preservation and distribution of hydrocarbons.Research results show the Wenchang A Sag has relative high geothermal gradient of 33.8°C/km on average.Such high gradient may facilitate maturing of organic matters and formation of hydrocarbons;Less compacted mudstone intervals distributed mostly in the Zhuhai Formation and Enping Formation.Such intervals may strengthen the capping capacities over hydrocarbons.Mudstone in the Zhujiang Formation contains no abnormal pressure.Instead, the interval is predominantly sealed under capillary pressure;The sag contain high-pressure composite temperature-pressure system.There are significant differences in energy of fluids contained in the 2 temperature-pressure systems.Hydrocarbons may migrate predominantly in vertical directions.Static temperature-pressure system in shallower formations may provide the most favorable conditions for enrichment and accumulation of hydrocarbons.In addition, hydrocarbon-bearing system in the Enping Formation can be considered as key exploration targets.Relevant research results may provide valuable references for exploration operations in the Pearl River Mouth Basin.

    • 摘要: 为研究准噶尔盆地北三台凸起断层对油气成藏的影响,在地震资料解释的基础上,结合区域构造、岩性组合、黏土矿物组成、压力分布、已知油藏特征等因素,对断层发育特征、形成机制及其与油气藏关系进行了描述与探讨.结果表明:该套断层具有"垂向层控性"、"平面多边性"特征,属于典型的多边断层,主要是细粒沉积物在密度反转作用机制下形成的;多边断层发育的地层下部紧邻二叠系平地泉组烃源岩,在油气聚集成藏过程中起到了运移通道的作用,密集的空间断层网络为油气藏局部连片提供了条件,在精细勘探中应当高度重视多边断层的解释与分析.该研究对北三台凸起的油气滚动勘探和油藏精细评价有一定的指导意义.%In order to investigate the effect of fault in Beisantai bulge in Junggar basin on oil and gas accumulation, the development characteristics,forming mechanism and their relationship with reservoirs are described and dis-cussed,based on seismic interpretation,regional structure,lithological association,clay mineral composition, pressure distribution and known reservoir characteristics. The results show that the fault is a typical polygonal fault, with"vertical strata-bound attribute"and"planar polygonality",which are formed by fine-grained sediment un-der density inversion effect. The lower part of the formation where polygonal faults are developed is close to source rock in Pingdiquan formation,Permian System and acts as migration pathway during oil and gas accumulation. The dense spatial fault network provides conditions for local connectivity of reservoirs and the interpretation and analysis of polygonal fault should be strengthened during fine exploration. The research provides guidance for oil and gas pro-gressive exploration and reservoir fine evaluation in Beisantai bulge.

    • 摘要: 金湖凹陷油气运移、聚集、成藏与断裂的展布、发育程度密切相关。为了认识断裂发育区油气分布规律以及断裂对油气富集程度的控制作用,运用分形理论对金湖凹陷断裂体系进行研究,利用研究区已落实的油气藏分布,分析断裂与油气分布关系。结果表明,断裂面积信息维在1.530~1.685之间有利于大油藏形成和保存;断裂信息维在1.655~1.832之间的高值区,断块被进一步分割复杂化,导致油气分布支离破碎,使得油气藏小而碎;有利于油气聚集成藏的分维下限值为1.483。应用信息维法对断裂体系分维计算结果表明,断裂面积信息维高值区与油气藏分布区吻合较好。在此基础上,分析预测了金湖凹陷下一步勘探优选区。

    • 摘要: 输导体系是烃源岩与圈闭联系的物质体现,是衡量圈闭有效性的重要标准.本文结合东营凹陷的地质特征及层序地层格架,在盆地输导体系要素研究基础上,建立东营凹陷的输导体系格架,分析盆地输导体系的平面和剖面特征:平面上,油气以生油洼陷为中心向四周放射状运移,形成以生油洼陷为中心的复环带状分布的特点,油气藏的平面分布特征明显地受输导体系构成方式的控制(反演),输导体系平面分布特征又明显受到沉积体系展布与断裂分布的制约(正演);剖面上,东营凹陷在不同的构造时期输导体系存在差异性,在盆地的不同构造部位发育不同类型的输导体系.

    • 摘要: The Dongtai depression is the richest region of petroleum resources in the Subei Basin of Eastern China. Temperature data from 54 system temperature wells and 243 test wells are used to calculate the subsurface formation temperature at the depths between 1000 and 3500 m and the bottom boundary temperature from the Sanduo Formation (E2s) to Taizhou Formation(K2t) ,and the present-day geothermal gradient, respectively. The distribution of geothermal field in the Dongtai Depression is divided into a few independent subunits like sags and sub-sags. In general, the temperature linearly increases with depth and the geothermal gradient in shallow formation is lower than that in the deep formation. The geothermal gradients are 22 ~30 °C/km and 28 ~ 38°C/km, respectively, for formations from Sanduo to Dainan (E2s-E2d) and formations from Funing to Taizhou (E1J~-K2t) , averaging is about 30 t/km, which indicate the influence of structures of sedimentary rocks on geothermal gradients. The general pattern of temperature at different depth is higher in the positive tectonic units and lower in the negative tectonic units, which is similar to the geothermal gradient. The geothermal field of the Dongtai depression is warm, which is governed by the structures, the thickness of sedimentary, deep faults, groundwater, and radioactive heat production in the strata. Most parts of the Dongtai Depression is still in liquid oil window, the majority of petroleum reservoirs distributes at the underground golden zones of hydrocarbon exploration and development where temperatures are over 60 t , and liquid oil migration is at depth of 20 km. The finding of temperature pattern and distribution of oil and gas fields can provide some insights for future exploration.%东台坳陷为中国东部苏北盆地油气资源最丰富的地区.为了加深对东台坳陷地温场和油藏关系的理解,根据符合地温场研究要求的54口井连续测温资料和243口井试油温度数据,获得了深度1000~3500 m地温、E2s-K2t各层位界面地温和各层地温梯度.地温场分布以凹陷或次凹成独立单元,地温随深度加深而线性增高,地温异常不明显.地温梯度总体呈现“浅层低、深层高”的特点,E2s-E2d地温梯度总体在22 ~ 30°C/km之间,E1f-K2t在28 ~ 38°C/km之间,平均约为30°C/km.不同深度的地温和地温梯度分布模式相似,正向构造单元高,负向构造单元低;而不同层位的地温分布规律则相反,即凹陷内温度高,凸起和隆起上的温度低.基底构造形态、沉积盖层厚度、深大断裂、地下水、地层放射性生热等因素决定了该坳陷总体为温盆特征.大部分地区目前还处在油气液态窗内,绝大多数油藏分布高于60°C的油气勘探开发黄金区域.
