对于低渗透油田往往伴随着更加严重的油藏非均质性,地质条件非常复杂,含油层系多,物性变化大,油藏类型多样,为了解决层间矛盾问题,均普遍采用了分层开采的开发方式。分层采油工艺能够有效防止层间干扰,减少层间矛盾,保持各油层的均衡开采,提高整个油田的采收率,因此其技术性能是否先进、是否具备适应性,将直接影响油田的整体开发效果。下面以陇东油田里74井为例,谈谈我对分采技术的应用及效果评价。
For low-permeability oil fields, the more serious reservoir heterogeneity is often accompanied by complicated geological conditions, many oil-bearing formations, large changes in physical properties and diverse reservoir types. In order to solve the problem of interlayer conflicts, stratified mining The way of development. Stratified oil recovery technology can effectively prevent inter-layer interference, reduce the contradiction between layers, maintain the balanced production of each reservoir, and improve the recovery rate of the whole oilfield. Therefore, its technical performance is advanced and its adaptability will directly affect the overall development of the oilfield effect. Here to Longdong Oilfield 74 wells, for example, to talk about my application of sub-mining technology and the effect of evaluation.
