【摘要】 泌阳凹陷是东部断陷盆地中“小而肥”的富油凹陷,经历了近三十年的勘探开发油气进入高成熟勘探阶段,油气藏类型也转向了隐蔽油气藏的勘探阶段。近两年随着泌阳凹陷在北部稠油-超稠油热采试验取得一定的进展,对于古城-高庄地区的新一轮勘探开发也提上日程,因此,研究复杂断裂带的构造及控油作用,预测下部勘探的有利目标区带成为论文的主要内容。2007年新采集的三维地震资料具备了复杂断块的精细勘探的物质基础。首先,以井震对比关系良好的井作为控制点,运用三维地震的立体构造解释、三维可视化解释、穿胡同剖面验证闭合等技术手段进行层位的解释,并总结出运用变换显示功能、连续多线对比、叠后处理和穿胡同剖面法等方法对小断层进行精细解析;通过多种技术方法的应用理顺了复杂断裂带断层的切割关系,合理解剖古城地区复杂构造面貌。其次,从古城地区的构造面貌、成因演化入手,分析复杂断裂带的形成机制、油气藏形成条件,探讨了构造对油气成藏控制作用。在总结了该区构造、储层及构造对油气的控制之后总结了工区的油气分布规律。最后对新发现和落实的圈闭进行综合评价,并从中优选出有利目标提出部署建议。本着整体解剖、整体评价、整体再认识古城-高庄地区的构造特征的原则,系统进行了断裂的精细解释,解释中首次引进走滑构造模式,认为北西向断层是在地层沉积晚期受构造左旋形成的走滑断层,切割一系列北东向北掉断层,构成现今构造格局。通过对油气成藏主控因素解剖确定了在古城、井楼-高庄宽缓鼻状构造背景下的断层、不整合面对油气成藏的双重控制作用。在论文的完成过程中,利用整体再认识的研究成果,合理解释了老油田内部局部地区油水关系解释不清的原因,并通过综合研究提出不同构造带上的井位部署的建议。更多还原

【Abstract】 After almost three decades of exploration and development, Biyang depression which is the "small and fat" oil-rich depression in the eastern rift basin in china, has entered a high mature stage of exploration. The past two years, with heavy-ultra-heavy oil thermal recovery pilot in the north of Biyang Depression made some progress, the exploration and development of gucheng - gaozhuang area is also put on the agenda; therefore, studying the construction and oil control role of complex fault zone and predicting a lower favorable exploration target zone become the main contents of this paper.The new three-dimensional seismic data which was collected in 2007 provides the material basis with the detailed exploration for the complex fault-block. First of all, the horizon is explained by using the three-dimensional structural interpretation, the interpretation of three-dimensional visualization, wearing alley profile verification closure and other technical means, small faults are finely resolved by using transformation display function, a continuous multi-line contrast, post-stack processing, wearing alley profile and other methods which are concluded, and the relationship between faults cutting in the complex fault zone is streamlined and the gucheng region’s complex structural outlook is reasonably dissected through a variety of techniques and methods. Second, the formation mechanism of the complex fault zone, and the oil and gas reservoir formation conditions are analyzed, and the structural control effect on hydrocarbon accumulation is discussed by starting with the structural appearance and the causes of evolution in gucheng region. In conclusion, the oil and gas distribution in the work area of is summed up after the structure, reservoir and the control of oil and gas structures summed up. Finally, the newly discovered and implemented traps are comprehensively assessed, a favorable target is optimized,and the deployment of recommendations is made.The precise interpretation of the faults in gucheng - gaozhuang region is systemicly analyzed With the principle of overall anatomy, overall evaluation, and the overall re-understanding of the structural characteristics. In interpretation, the strike-slip tectonic model is introduced for the first time.It is suggested that the NW-trending faults are strike-slip faults which are formed in the Sedimentary late by the L-shape structure, cut off a series of north-east faults,and constitute the present tectonic pattern. The role of the gucheng-jinglou-Gaozhuang relief nose structure in the context of fault and unconformity dually controlling hydrocarbon accumulation is defined through the dissection of factors controlling hydrocarbon accumulation. In the paper, the unclear reasons of the relationship between oil and water in some areas in the old oil fields are reasonably explained through an overall analysis of re-understanding research results, and the well placement recommendations in different tectonic belts are proposed through the integrated study.更多还原
