【摘要】 南堡油田位于南堡凹陷的南部,发育南堡1号、南堡2号、南堡3号、南堡4号和南堡5号构造等五个有利构造带,具有构造继承性发育,环绕南堡凹陷主要生油次凹分布,生储盖组合条件优越、圈闭十分发育,油气资源丰富的特点。目前南堡油田已进入勘探评价和开发方案设计阶段,以往勘探成果表明,南堡油田是一个大型油田。本论文以三维地震资料为基础,通过钻井、地质、测井与试油试采资料相结合,开展地层对比、油藏特征、精细构造解释及储层预测等工作。在精细构造落实、储层预测、成藏规律及油层分布研究等工作基础上,寻找有利目标区块。通过对有利目标区块进行经进行精细刻画,开展南堡油田井位论证及钻井地质设计。通过与生产紧密结合,开展随钻解释工作,不断将新井成果应用到构造解释当中,不断提高对地下地质情况的认识,及时为勘探开发井位部署与调整提供依据。通过全区构造解释,落实了1~5号构造明化镇组-沙一段底7个层位的整体构造形态及断裂空间展布。通过对有利目标区的主要含油层位精细构造解释,共落实有利层圈闭295个,层圈闭面积785.2 km~2,为勘探开发部署工作提供了有利支持。在精细构造解释基础上,通过对有利目标区精细储层刻画,落实了有利目标区主力油层储层分布情况,为目标井位部署提供坚实的依据。通过南堡1~5号构造全区地震属性提取及储层预测,落实了下第三系沙一段到东一段沉积展布规律。南堡1~5号构造中浅层明化镇组、馆陶组河流相及东一段三角洲前缘沉积储集物性好,储层厚度大,分布范围广,油源来自下第三系,形成下生上储式成藏组合,油气分布主要受构造控制,断层是主控因素,以低幅度背斜构造油藏、断块(鼻)构造油藏为主。中深层东二段、东三段储层主要是扇三角洲前缘沉积,形成以自生自储为主的成藏组合,油臧受构造和储层分布双重因素控制,形成构造-岩性油臧。通过研究表明南堡2号构造东部处于三个次凹中间,油源条件好,断层发育,中浅层储层物性好,在本区发育的三个背斜构造带是油气聚集有利部位。

【Abstract】 Nanpu oilfield is located south of the Nanpu depression,development Nanpu NO.1-NO.5 favorable structural zone with structural inheritance and development, around Nanpu depression major oil source second concave distribution of reservoir-cap combination of favorable conditions,traps are well developed,the characteristics of rich oil and gas resources.Nanpu oilfield has entered the current exploration evaluation and development program design phase,the previous exploration results indicate that the Nanpu oilfield is a large oil field.In this thesis,the basis of three-dimensional seismic data,drilling,geology,well logging with the test oil test data combined to carry out stratigraphic correlation, reservoir characteristics,fine structural interpretation and reservoir prediction and so on.The implementation of the fine structure,reservoir,accumulation and distribution of oil on the basis of such work to search for the target block.By enabling target block to be fine by the characterization,to carry out oilfield drilling wells and geological proof design.Closely integrated with production,drilling carried out to explain the work,the results continue to be applied to construct a new well to explain them,constantly improve the understanding of the underground geology,exploration and development wells in time for deployment and provide the basis for adjustment.Structural interpretation by region,implemented 1 to 5 out of Minghuazhen group structure - a bottom sand layer 7 forms the overall structure and spatial distribution of faults.Favorable target areas on the main oil-bearing layer fine structural interpretation,a total of 295 traps in the implementation of favorable layer, layer trap area of 785.2 km~2,for the exploration and development has provided a beneficial support.In the fine structural interpretation based on the favorable target areas through fine reservoir characterizations of the implementation of a favorable target areas the distribution of main oil reservoir in order to target wells to provide a solid basis for the deployment.Nanpu 1-5,the region structural seismic attribute and reservoir prediction,the implementation of the Lower Tertiary section of the eastern section of sand deposition distribution rules.Nanpu 1-5,in the shallow structure Minghuazhen,Guantao group and the East section of the fluvial delta sediment good reservoir properties,reservoir thickness of the large,wide distribution,from the Lower Tertiary oil source form xiasheng the combination of storage-type reservoir,oil and gas distribution is controlled by structure,the fault is the controlling factor, low-amplitude anticline reservoir block(nose) structures the main reservoir.In deep East Erduan,East three sections reservoir is mainly fan-delta front deposits,formed mainly of self storage reservoir from the combination of reservoir structure and reservoir distribution by two factors control the formation of structure - rock oil possession.Studies show that the South through the Fort 2,three times in a concave structure among the eastern,oil source conditions are good,faults and good in the shallow reservoir,three in the area developed anticline zone is favorable for hydrocarbon accumulation area.
