摘要：

为确定大庆SN油田东部过渡带油水界面，综合钻井、测井、地震资料，结合岩心含油产状分析和老井油水层二次解释，基于双相介质理论的叠后属性油气检测以及基于叠前地震波形指示反演的流体识别等技术，探讨构造油气藏外扩区油水边界的综合确定方法。研究区油水边界具有以下特征：岩心含油产状为油斑以上；测井解释外推为油层或油水同层；叠后属性低高频能量比大于0.85；叠前反演预测含水饱和度小于75%。因此，以“井点定深度、地震定边界、动态来验证”为原则，从“点—线—面—空”，经过综合分析，确定最终油水边界位置。研究成果有效指导了研究区外扩评价部署，对同类型构造油田油水边界研究具有参考意义。

Abstract:

In order to determine the oil-water contact in the eastern transitional zone of the Daqing SN oilfield, based on the drilling, logging, and seismic data, together with the core oil occurrence analysis and the reinterpretation of oil/water layers in existing wells, a comprehensive method for determining the oil-water boundary in the extension zone of structural reservoirs was discussed by using the techniques such as hydrocarbon detection through post-stack seismic attributes based on dual-phase medium theories and fluid identification based on pre-stack seismic waveform indication inversion. The oil-water interface in the study area exhibits the following characteristics: (1) oil patch or higher level occurs in cores; (2) oil layers or oil-water layers are extrapolated on the basis of logging interpretation; (3) in post-stack attributes, the energy ratio of low frequency to high frequency is greater than 0.85; and (4) the predicted water saturation from pre-stack inversion is less than 75%. Therefore, following the principle of “depth of oil-water contact determined by well data, boundaries of oil and water distribution determined by seismic data, and validation by well performance”, and through comprehensive analysis from point to line, plane, and then space, the final position of the oil-water interface was determined. The research results effectively guide the extention deployment and evaluation in the study area, and are referential for delineating the oil-water boundaries in similar structural reservoirs.

Key words: structural reservoir, oil-water contact, logging-seismic data, post-stack attribute, pre-stack inversion, comprehensive analysis
