曙光油田沙三段发育大凌河、莲花两套含油层系属浊流沉积体系,由于其分布主要受构造和物源双重因素控制,油藏呈零散状分布,且规模大小相差悬殊,勘探难度较大。随着勘探开发进程的不断深入,油田动静态资料的丰富,开展“三老”资料复查和对储层特征的再认识,结合“四性”关系研究,能够有效地提高老井试油试采成功率,为曙光油田老区滚动勘探工作开创新的途径。
The Shusan Section of Shuguang Oilfield has two sets of oil-bearing sedimentary systems, Daling and Lotus. Because of its distribution mainly controlled by the dual factors of structure and provenance, the reservoirs are distributed in a scattered pattern with large differences in scale and exploration difficulty Larger. With the deepening of the exploration and development process, the abundance of dynamic and static data in oilfields, the review of “three old” data and the re-understanding of reservoir characteristics, combined with the research on the relationship of “four sexes”, the old well The success rate of trial oiling and test mining opens up new avenues for the rolling exploration in the old area of Shuguang Oilfield.
