南堡油田构造特征及储层预测研究
|
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。
