【摘要】：在对研究区潜力层位进行预测过程中,对储层特征的研究是不可缺少的。本次研究的BN区块隶属于博兰(Pollan)油田,位于美国德克萨斯州西北部,区块在大的区域上位于美国的二叠盆地,该区块需要对油层进行划分与对比、储层特征以及潜力层位等问题进一步开展深入研究。在研究区内井进行筛选,选择标准井,选择钻遇本区所有层系,标志层明显,完钻深度高于全区的31039井做为分层标准井,采用“旋回对比,分级控制”的对比方法,对研究区31口井、5套层系,9个油层组进行对比统层工作,在此基础上,对储层的构造特征进行了研究,重新划分了油水界限,将原油水界限由-5500ft上调至-5490ft。在此基础上,对研究区储层厚度进行划分,孔、渗、饱参数进行了解释,并将解释结果和实际情况相结合,综合分析研究储层参数分布特征,根据解释数据及结果,利用容积法对研究区各个油层进行了地质储量计算及储层评价,综合上述研究成果,进而对研究区曲线特征、构造特征、录井特征、有效厚度分布规律、物性参数及油田的生产动态数据进行综合分析,最终预测出潜力层位,为下一步的生产开发提供依据,研究优势储层分布规律,寻找剩余油富集区,从而维持油田经济有效的生产。
[Abstract]:The study of reservoir characteristics is indispensable in the prediction of potential horizon in the study area.The BN block in this study belongs to the Boran Pollan oil field, located in the northwestern Texas of the United States. The block is located in the United States' Permian Basin in a large area, and the block needs to be divided and correlated.Further research on reservoir characteristics and potential horizons has been carried out.In the study area, the wells are screened, the standard wells are selected, and the 31039 wells with marked layers and higher drilling depth than the whole area are selected as the stratified standard wells. The contrast method of "cycle contrast, grading control" is adopted.On the basis of the study of 31 wells and 5 sets of layers and 9 reservoir formations, the structural characteristics of the reservoir are studied, and the boundaries of oil and water are re-divided, and the original limit of oil and water is raised from -5500ft to -5490ft.On this basis, the reservoir thickness, pore, permeability and saturation parameters in the study area are interpreted, and the distribution characteristics of reservoir parameters are comprehensively analyzed and studied according to the interpretation data and results, by combining the interpretation results with the actual conditions.The geological reserves and reservoir evaluation of each reservoir in the study area were calculated by volume method, and the above research results were synthesized, and the curve characteristics, structural characteristics, logging characteristics, effective thickness distribution law of the study area were further analyzed.Through comprehensive analysis of physical property parameters and production performance data of oil fields, potential horizon is finally predicted, which provides the basis for further production and development, studies the distribution law of superior reservoirs, and looks for remaining oil-rich areas.Thus maintaining the economic and effective production of the oil field.
