Abstract
Entering into high water cut stage, Lamadian Oilfield presents high composite water cut, low recovery degree, invalid or inefficient water circulation, scattered remaining oil and difficult potential tapping. In order to produce maximum remaining oil, the production status under well pattern in each series of layers, the producing status of each kind of reservoirs, and the origin and distribution of remaining oil are figured out combined with current stable production situation. On this basis, the fine description for reservoir sandbody and structure and the accurate judgment to the characteristics of remaining oil distribution are achieved by fine reservoir dissection technology, integrated logging-seismic data and dynamic analysis method. Finally, the research on the method of tapping remaining oil potential by high efficient smart well in oil enriched area is implemented. Horizontal well, high angle directional well and vertical well are adopted to produce scattered remaining oil under the principle of" less well and high efficiency", which has great significance for improving recovery factor and providing a new way to continue oil production.关键词
