| 摘 要： | 葡北油田东部空白区断层分割强、 油水分布复杂，本文针对这种情况对研究区开展了井震结合沉积微相研究。首先依据岩心、 录井和测井曲线等资料建立了葡萄花油层等时地层格架，在葡萄花油层取心井段单井岩心沉积微相精细分析基础上，建立了葡萄花油层水下分流河道主体、 水下分流河道、 水下分流河道边部、 主体席状砂、 薄层席状砂、 水下分流间泥6种测井相模式；其次精细刻画了研究区开发区块沉积微相，总结了砂体的演化规律和葡萄花油层沉积微相特征，并且用井震结合法绘制了全区沉积微相图；最后，在以上工作的基础上研究了“断-砂”匹配方式对成藏的影响。研究表明，断层与砂体的匹配关系是控制成藏的主要因素，砂体与断层在构造高部位以高角度相交控制的井试油结论最好。该研究结果为葡北油田下一步的勘探开发提供了一定的地质依据。

| Abstract: | The fault segmentation of blank area in the east of Pubei oilfield is strong, and the distribution of oil and water is complex. In view of this kind of situation, we did sedimentary microfacies research in study area by well seismic combination method. First, we established isochronous stratigraphic framework of the east of Putaohua oil layer by core and logging data, we also established six well logging facies models, including main underwater distributary channel, underwater distributary channel, edge of underwater distributary channel, main sand sheet, sand sheet and bay mud between distributary channels,Secondly, we described the sedimentary microfacies of development area, summarized the evolution of sand and sedimentary microfacies characteristics of Putaohua oil layer, and drew the sedimentary microfacies of study area by well seismic combination method,Finally, on the basis of the above work, we study the affect of the match of fault and sand in oil accumulation model. It shows that the match of fault and sand is the main factor in oil accumulation, the wells controlled by fault with high angel in the structural high position have better test conclusions. The study provides geological basis for the next step of exploration and development in oil field. |
