【摘要】：随着油田开发的不断深入,萨南开发区开发进入中后期,含水率上升越来越快,产量加速减少,经过长时间的开发后,储层中剩余的可采储量也越来越少,地质储量和可采储量逐渐失去平衡,这种矛盾日益明显,因此,为了解决这些问题,为了保证油田产量的稳定,寻找新的储量资源,对于还没有开发的储量,要最大限度的将其开采出来是唯一的方法。油水同层段储层的储量已经占了有日常储量的很重要的一个部分,尤其是油水同层段储层中的偏油层,又有一定的挖掘潜力,因此为了解决储采比问题,落实稳产目标,使油田的储量不损失,以萨南开发区为典型区块开展了油水同层段偏油层识别方法研究。首先,对取心井岩心利用岩石热解技术、热解蒸发烃气相色谱技术、荧光显微图像技术等进行实验,并将其与录井资料结合起来,分析油水层的响应特征,重新综合判定了整个萨南油田萨东油水过渡带、萨西油水过渡带、南一区到南三区、南四区到南八区四个区块的油水同层段深度。然后通过取心井的岩心分析资料,试油资料和测井资料统计和分析,再一次确定了萨南开发区储层的油水同层以及其相应的四性关系;再利用相渗曲线法,经济极限法,压汞法和经验统计法来确定研究区油水同层段偏油层的物性下限;进而根据物性标准和测井数据建立电性与物性交会图版,确定出萨南开发区储层油水同层段偏油层电性下限,准确识别出油水同层段偏油层段,为油田后期动态开发调整方案的制定提供更可靠的依据。
[Abstract]:With the deepening of oilfield development, the development of Sanan Development Zone enters the middle and late stage, the water cut rises more and more quickly, the output decreases rapidly, and after a long period of development, the remaining recoverable reserves in the reservoir become less and less. The contradiction between geological reserves and recoverable reserves is becoming increasingly out of balance. Therefore, in order to solve these problems, to ensure the stability of oilfield production and to find new reserves, for reserves that have not yet been developed, It is the only way to extract it to the maximum extent possible. The reserves of reservoirs in the same formation of oil and water have already taken up a very important part of the daily reserves, especially in the reservoirs of the same formation of oil and water, which has a certain potential to excavate. Therefore, in order to solve the problem of the ratio of reservoir to production, and to implement the goal of stable production, In order to avoid the loss of oil reserves, the identification method of oil-water reservoir in the same zone is studied in this paper, taking Sanan Development Zone as a typical block. Firstly, the core of coring well is tested by using rock pyrolysis technology, pyrolytic vaporization hydrocarbon gas chromatography technology, fluorescence microscopic image technology and so on, and the response characteristics of oil-water layer are analyzed by combining it with logging data. The depth of the same zone of oil and water in the four blocks from South one to South three and from South four to South eight has been determined by re-synthesizing the oil and water transition zone of the whole Sanan oilfield, the oil and water transition zone of Saxi oil and water. Then through the core analysis data of coring well, oil test data and logging data statistics and analysis, once again determine the reservoir in Sanan development zone and the corresponding four properties; The lower limit of physical properties of the oil-water layer in the same zone is determined by using the phase permeability curve method, the economic limit method, the mercury injection method and the empirical statistics method. Furthermore, according to the physical property standard and logging data, the electric and physical intercourse meeting chart is established, and the lower limit of electric property of the oil / water partial oil layer in the same section of the reservoir in Sanan Development Zone is determined, and the partial oil layer section of the same oil and water zone is accurately identified. It provides a more reliable basis for the formulation of the adjustment scheme of oilfield later dynamic development.
