摘要
D区块为岩性—构造油藏,具有边底水特征。文章通过对D区块注水开发特征分析,认识到:该类油藏注水开发时应控制注、采速度,温和注水,温和采油。通过开发实践,D区块适宜的注采比为0.8—1.0,适宜的井底流压为2.5—3.5MPa。
The D-oil block belongs to a lithology-structure reservoir with edge water features.Based on the analysis of the waterflooding characteristics of D block,it is recognized that the reservoir should control the speed of water injection and oil production,and carry out moderate water injection and oil production.according to the development practice,the suitable injection-production ratio is between0.8-1.0,and the appropriate flowing bottomhole pressure is beween2.5-3.0MPa.
