    • 摘要: 以北部湾盆地涠西南凹陷流沙港组为例,利用密井网资料,结合现代沉积考察,建立了扇三角洲沉积储层定量地质知识库.通过分析研究,将研究区流沙港组扇三角洲前缘沉积细分为5种微相类型,这些微相砂体有6种叠置模式.对现代扇三角洲沉积考察的定量数据采集统计分析结果显示,辫流坝长宽比为1.65~4.25,辫流坝与辫状水道宽度比为0.65~5.00,该数据为刻画实际地下地质体的展布提供了重要依据.扇三角洲地质知识库显示,辫状水道宽厚比为150~200,辫流坝宽厚比为170~220,分支水道宽厚比为180~230,河口坝宽厚比为400~545.依据地质知识库数据,研究区注水井部署方案将注采井距定在420~800m,现场实施该方案后注水效果好.

    • 摘要: After more than 50years of the exploration and development,Daqing Changyuan Oilfield is now in the stage of dense well pattern and single-bed production. The development geological task is to identify the connectivity of sand bodies and the narrow channel boundary between wells.Based on high-density 3Dseismic data and well development information,a sand body prediction model for typical Changyuan Block is established with integrated well-seismic data inversion.Single- channel boundary of composite sands and narrow channel sandbodies between wells are identified by the geologic statistics inversion.It is concluded that the integrated well-seismic data inversion synthesizes the advantages of vertical and lateral high density information, and it is suitable for cross-well sand body identification in the oilfield development late stage.%大庆长垣油田历经五十多年的勘探与开发,目前处于高密井网、细分单层开采阶段.为了确定砂体的连通关系和井间窄小河道的边界位置,在高密度三维地震资料和开发井信息基础上,综合钻井的纵向信息和地震横向高密度信息的优势,采用井震结合反演技术建立砂体预测模型.通过地质统计学反演,识别了复合砂体单一河道边界及井间窄小河道砂体.该方法适用于类似油田开发后期井间砂体的识别.

    • 摘要: Taking the high-sinuosity distributary-channel reservoir in the close well-spacing block of Xingbei Oilfield as an example,based on the depositional model of the reservoir architecture theory,with the help of analytical hierarchy process,the reservoir architectures were analyzed in detail in the following four aspects:channel complex,individual channel,point bar and lateral accretion body within the point bar,on the basis of the mutual verification of “the static remained oil analysis” interpreted by the close coring well and watered well logging and " the dynamic remained oil analysis" conducted by the numerical simulation of 3D architectural-element model oil reservoir,the distributed modes of the remained oil in the high-sinuosity distributary-channel reservoir were summarized.The achievements show that within the channel,the remained oil are primarily distributed on the upper part of the point bar;while outside the channel,the remained oil are mainly on the top of the point bar and the blocked part by the abandoned channel,the dead-ends of the overbank sandbody and the isolated overbank sandbody with the inefficient injection-production system,and moreover the thin-bedded overbank sandbody with much poorer developed degree.%以杏北油田密井网区高弯度分流河道储层为例,基于储层构型理论沉积模式,采用层次分析法,按复合河道、单河道、点坝、点坝内部侧积体四个层次对储层构型进行精细解剖,并在基于密闭取心井和水淹层测井解释的“静态剩余油分析”与基于三维构型模型油藏数值模拟的“动态剩余油分析”的相互验证下,总结高弯度分流河道储层剩余油分布模式.结果表明:在河道内,剩余油主要分布于点坝上部;在河道外,剩余油主要分布于点坝顶部和废弃河道遮挡的部位、注采系统不完善的溢岸砂体末端和孤立溢岸砂体内以及动用程度较差的薄层溢岸砂体中.

    • 摘要: Low-sinuosity distributary channel reservoir is an important reservoir type of Xingbei oilfield and it is of great significance to further study its reservoir architecture characteristics for the adjustment and potential tapping.Based on the data of cores,wire-line logs and production performance from close well-spacing block,the reservoir architecture of low sinuosity distributary channel in Xingbei oilfield was finely analyzed by using "hierarchy analysis and depositional pattern guidance" with two primary hierarchies which were the determination of amalgamated channels and overbank sandstone bodies and the contact relationships among solitary channels.The 3-D reservoir architecture model was then established.Based on the static data of sealed coring wells and water-cut well-logging interpretation results and the production performance data,the waterflooding features of different periods and distribution of remaining oil were analyzed.Subsequently,the distribution of remaining oil was verified by numerical reservoir simulation based on 3-D reservoir architecture model.Finally,the distribution of remaining oil controlled by the reservoir architecture was summarized and demonstrated as follows:within the channel,the remaining oil volumes are enriched in the top and edge of the channel,the lower areas controlled by mud or calcareous interbeds between individual channels and undeveloped areas just connecting with low-permeability overbank sands.Outside the channel,they are mainly in low-permeability overbank sands,end of the overbank sands and the isolated sandstone bodies with imperfect injection-production systems.%低弯度分流河道储层是杏北油田的重要储层类型,深入研究其储层构型特征对于油田调整挖潜意义重大.综合密井网岩心、测井和生产动态等资料,采用“层次分析和模式指导”的方法,分“复合河道和溢岸砂体、单期河道及其相互接触关系”两个主要层次开展储层构型精细解剖,构建了三维储层构型模型.基于密闭取心井、水淹层测井解释资料和生产动态数据分析了不同时期的水淹特征和剩余油分布,并通过基于三维构型模型的油藏数值模拟对剩余油分布模式进行验证,最终总结出不同储层构型控制下的剩余油富集模式.结果表明,在河道内,剩余油在顶部、边部、河道间夹层控制部位以下以及仅与低渗溢岸砂连通造成注采不完善的河道内部富集;在河道外,剩余油在河间物性较差的溢岸砂内、注采不完善的溢岸砂末端和孤立砂体内富集.

    • 摘要: 测井资料和地震资料是油田勘探开发过程中两种最基本的原始资料,在储层预测等精细油藏描述中发挥着重要作用,但由于二者采集的时间、方法及分辨率不同,导致反映的储层信息不一致,造成了储层预测及描述的多解性,影响剩余油开发效果.为此,系统分析了大庆长垣油田北部区块密井网区影响井震匹配性的因素,针对性地提出了地震重采样、测井曲线标准化和趋势约束层位解释技术等解决方案,有效提高了测井与地震资料的空间匹配程度,并在大庆长垣油田北部区块萨尔图油层密井网约束反演储层预测中进行了实际应用,厚度2m以上河道砂体预测符合率达到了80%以上,取得了较好的应用效果.

    • 摘要: 综合应用铸体薄片、物性分析等资料,以鄂尔多斯盆地华庆地区长8油组为例,对密井网条件下低渗致密砂岩内部的钙质胶结条带进行了研究,明确了其基本特征,阐明了不同位置胶结条带的发育控制因素,建立了密井网条件下钙质胶结条带的空间展布模式.研究表明,华庆地区长8油组砂岩中,钙质胶结条带广泛发育,主要成分为晚期铁方解石.不同发育位置的钙质胶结条带发育主控因素不一,整体胶结式发育主要受控于粒度,中部式主要受侧向临近泥页岩和长石溶蚀影响,顶底式则主要受到粒度和泥页岩发育程度配置关系影响.不同沉积微相组合和构型界面控制了钙质胶结条带的垂向分布,平面上钙质胶结条带主要呈团块状、条带状分布于研究区中部远离物源的分流河道末端及其附近河口坝中部.总体上,密井网条件下钙质胶结条带在空间上呈厚层粗粒砂体内部"顶底胶结厚延伸远中部胶结薄延伸近"和薄层砂体"整体胶结薄延伸近"的展布模式.%Using data from casting sheet images and physical property analyses, this study investigates calcite-cemented strips in compact sandstones of low-permeability under close well-spaced conditions, as exemplified by the Chang-8 oil formation in the Huaqing area of the Ordos Basin. Specifically, their basic characteristics are analyzed, the controlling factors for the development of them at different locations are identified, and a spatial distribution model for calcite-cemented strips under close well-spacing conditions is built. The results of the study show that calcite-cemented strips were widely developed in the sandstones of the Chang-8 oil formation in the Huaqing area, and mainly comprise late-stage ferrous calcites. The primary controlling factors for their development vary with the location of development. In particular, their development is primarily controlled by granularity, lateral adjacent mud shales and feldspar corrosion in the middle, and by the dispositional relationship between granularity and degree of mud shale development at the top and bottom. Their vertical distribution is controlled jointly by a combination of sedimentary microfacies and a configurational interface. Horizontally, they mainly take on a crumby structure and have a zonal distribution at the end of the distributary river way, far away from the provenance in the middle of the study area, and in the middle of the nearby estuary dam. Overall, the spatial distribution of calcite-cemented strips under the close well-spacing condition is characterized as follows: (1) in the thick-layer coarse-grained sands, calcite cementation is thick and far-stretching at the bottom and top, but thin and near-stretching in the middle;(2) in the thin-layer sands, calcite cementation is thin and near-stretching.
