【摘要】：S油田为T盆地台北凹陷西部主要区块之一,为典型低幅度岩性构造油藏。本文利用区块岩石物理实验数据,对区块储层地质特征进行统计分析总结,认为S区块属于低含油丰度、低孔、低渗、低电阻率储层,并对储层四性关系进行了研究,分析结论为:岩性是基础,物性是条件、电性是核心、含油性是目的。S区块储层含油性在构造背景下主要受岩性和物性控制,分析发现较低的构造幅度、复杂孔隙结构、较高地层水矿化度和高束缚水含量是导致区块油层电阻率较低的原因。利用岩心刻度测井方法,对区块主要储层参数(泥质含量、孔隙度、渗透率、含水饱和度等)模型进行重构;对测井、录井、地质、试油等数据进行充分挖掘,利用微差识别、阵列感应侵入、感应/侧向联测、双重孔隙度曲线叠加、图版、核磁共振测井等方法对流体性质进行定性识别;利用油水层识别因子方法对低阻油层进行定量识别;结合前人研究成果,假设渗流网络与导电网络具有相似性的条件下,利用前人研究成果,建立了S区块相对渗透率,构建了S区块产水率方法。通过统计,该方法在研究区块具有一定适用性,能基本满足生产评价的需求。在前人研究基础之上,在区块宏观地质背景条件下,充分利用测井、录井、地质、试油、岩石物理实验等基础数据,通过本论文的研究,形成了一套S油田储层参数评价计算和储层流体识别方法,提高了研究区块测井解释符合率;提出了利用测井方法计算相对渗透率方法,对储层产水特征进行分析,较好解决了油田生产中的问题。
[Abstract]:S oilfield is one of the main block of T basin in the west of Taipei depression, is a typical low amplitude lithologic structural reservoir. The physical experiment data of rock block, reservoir geology statistical analysis summary that S block belongs to the low abundance, low porosity, low permeability and low resistivity reservoir, and the reservoir four relations, analysis conclusion: lithology is the foundation, physical condition, power is the core, is the purpose of oil-bearing reservoirs of.S block in oil-bearing tectonic background is mainly affected by the lithology and physical property control, analysis shows that the low amplitude structure, complex pore structure, high salinity and high bound water content is the cause of the low resistivity reservoir block. Using the core scale logging method, the main reservoir block layer parameters (shale content, porosity, permeability, water saturation) model reconstruction; for well logging, logging, geological, test Oil data of sufficient mining, using differential recognition, array induction induction / lateral connection, invasion, dual porosity curve superposition, chart, NMR and other methods for qualitative identification of fluid properties; quantitative identification of low resistivity reservoir with oil and water layer identification factor method; combined with the results of previous studies, and the conductive percolation network hypothesis the network has the similarity conditions, using the results of previous studies, a S block S block construction relative permeability, water production rate. Through the statistical method, this method has certain applicability in the study area, can basically meet the production needs of the evaluation. On the basis of previous research, in the macro block geological background conditions. Make full use of logging, geological, logging, oil testing, rock physics experiment data, through the research of this paper, the formation of a set of S oil reservoir parameter calculation and evaluation of reservoir fluid The recognition method improves the coincidence rate of logging interpretation in the study area, and puts forward the method of calculating relative permeability by logging method, which analyzes the characteristics of reservoir water production and solves the problems in oilfield production.
