【摘要】：庙南区块包括庙130、庙134、庙22、嫩1及庙130西南的木210~庙132井区,工区内各区块受技术水平、资料等方面的限制始终没有开展过系统的油藏描述工作,做为新木油田的重要潜力区,该区域的砂体变化快、油水分布复杂,对该区域的潜力状况始终认识不够深入。针对上述问题,综合利用动静态各方面资料,通过多学科研究手段,在地震解释及储层预测的基础上,开展储层精细描述,分析各区块构造及断裂特征。对嫩1及木210~庙132区块采用稀疏脉冲和地质统计学联合反演技术对储层进行了反演,建立各区块精细等时地层格架。探讨各区块沉积微相类型、沉积微相及砂体空间展布规律。分析各区块储层平面、层内及层间储层非均质性。采用容积法对各区小层及单井控制地质储量进行复算,建立各区块精细三维地质模型,分析各区块注采关系及水驱控制程度,总结各开发区块剩余油成因及类型。对嫩1区块井网适应性进行分析,从油源、沉积、储层、圈闭及试油成果等综合考虑,认为构造缓坡区和高孔高渗区域是成藏的有利条件,优选3个有利区,部署评价井4口。
[Abstract]:The Miaonan blocks include Miao 130, Miao 134, Miao 22, Nen 1 and Miao 130 southwest of Mu-210 ~ Miao-132 well area. All the blocks in the work area have not been systematically described by reservoir description work because of the limitation of technical level and data, so as to be an important potential area of Xinmu Oilfield. The sand bodies in this area change rapidly and the distribution of oil and water is complex. In view of the above problems, comprehensive use of dynamic and static data, through multi-disciplinary research means, on the basis of seismic interpretation and reservoir prediction, the development of fine reservoir description, analysis of each block structure and fault characteristics. The inversion of reservoirs in blocks Nen 1 and Mu 210 ~ Miao 132 is carried out by using sparse pulse and geostatistics combined inversion techniques, and the fine isochronous stratigraphic framework of each block is established. The types of sedimentary microfacies, sedimentary microfacies and spatial distribution of sand bodies in each block are discussed. The heterogeneity of reservoir plane, interlayer and interlayer reservoir in each block is analyzed. The volume method is used to recalculate the controlled geological reserves of each small layer and single well, to establish three dimensional fine geological model of each block, to analyze the relationship between injection and production in each block and the degree of water drive control, and to summarize the origin and type of remaining oil in each development block. Based on the analysis of well pattern adaptability in N-1 block, considering the oil source, sedimentation, reservoir, trap and oil test results, it is considered that structural gentle slope area and high porosity and high permeability area are favorable conditions for reservoir formation, 3 favorable areas are selected and 4 evaluation wells are deployed.
