【摘要】：辽河坳陷西部凹陷南部兴隆台一马圈子潜山构造带北部,具有十分优越的油气成藏条件。2006年上报含油面积3.46km2,原油地质储量2094.8×104 t。该油藏具有世界上己知的最厚的油层、复杂的地质构造和风险较高的地面条件,通过对兴马潜山带南部中生界储层的预测,可进一步认清研究区油藏地质及其在开发过程中的特点,利用反演技术对储层进行预测,能够提高对研究区储层的进一步认识,并对同类油藏开发具有现实的指导意义。本文旨在利用录井取心、测井资料等技术,从岩石物理研究入手,开展了本区地层岩性重新认识、地层划与对比,从而对区域地质背景进行新的认识;并利用三维地震技术,以及Landmark工作站解释系统,TDQ技术成图等对研究区构造重新认识的同时并做出构造解释;结合岩心物性分析以及储层四性评价对研究区中生界储层进行了评价;以及通过多井约束三维稀疏脉冲反演技术以及JASON软件对储层进行反演分析,一方面通过三维地震资料波阻抗反演对空白区的储层横向展布进行预测,另一方面对已钻井的井资料进行储层对比统计分析,以实现储层预测。研究区中生界地层属于残留沉积,储层以火山角砾岩为主,中生界地层波阻抗为一套整体偏中高阻阻抗。在研究区中部中生界地层比较发育的部位反演效果比较好,对有利储层的发现有一定的指导意义。
[Abstract]:In the north of Xinglongtai Mahuan buried hill structural belt in the south of the western depression of Liaohe depression, it has excellent oil and gas accumulation conditions. The oil area of 3.46 km ~ 2 was reported in 2006, and the geological reserves of crude oil were 2094.8 脳 10 ~ 4 t. The reservoir has the thickest reservoir known in the world, complex geological structure and high risk surface conditions, through the prediction of Mesozoic reservoirs in the southern Xingma buried hill belt. The reservoir geology and its characteristics in the development process of the study area can be further recognized, and the inversion technique can be used to predict the reservoir, which can improve the further understanding of the reservoir in the study area and have practical guiding significance for the development of the same kind of reservoir. The purpose of this paper is to make use of the techniques of logging coring and logging data, starting with the study of rock physics, to carry out a new understanding of the lithology, stratigraphic division and correlation of the strata in this area, and to make a new understanding of the regional geological background, and to make use of the three-dimensional seismic technology. The Landmark workstation interpretation system is used to map the structure of the study area, and the structure interpretation is made at the same time, and the Mesozoic reservoir in the study area is evaluated by combining the core physical property analysis and reservoir evaluation. And through the multi-well constrained 3D sparse pulse inversion technology and JASON software to carry on the inversion analysis to the reservoir, on the one hand, through the three-dimensional seismic data wave impedance inversion to carry on the prediction to the reservoir horizontal distribution in the blank area, On the other hand, the well data are analyzed and compared to realize reservoir prediction. The Mesozoic strata in the study area belong to residual deposits, the reservoir is mainly volcanic breccia, and the Mesozoic formation wave impedance is a set of integral partial middle and high impedance. The inversion effect of Mesozoic strata developed in the middle of the study area is good, which has certain guiding significance for the discovery of favorable reservoir.
