摘要

千米桥潜山凝析气藏是大港油田发现的第一个大型裂缝性潜山凝析气藏。在勘探研究及储量计算基础上,利用现有并的试油、试采等动静态资料及生产特征,确定了断裂系统分布特征,明确了潜山“断裂发育、南高北低”及南北、东西2个“山梁”呈“厂”字分布的构造格局,确定了潜山储层类型应属于“微缝孔隙型”,与原认识“溶洞孔隙型”相比,更符合动态生产特征。为充分利用和有效开发千米桥潜山凝析气藏资源,提高储量动用程度,建立了可靠的地质模型,开展了油藏工程研究,为潜山凝析气藏的有效开发探索了一条成功之路。

Abstract

QianMiqiao Buried-hill condensate gas reservoir is the first fractured buried-hill condensate gas reservoir with large-scale found in Dagang oilfield. Through the application of the results of exploration and reserve calculation, production characteristics of exiting wells are analyzed according to the formation and production testing data. Then the fracture system distribution and structure pattern of buried hill are determined, which are characterized by "well-developed fracture with south high and north low" and east and west " mountain ridge " in shape of Chinese Character " 厂". It is confirmed that the buried hill reservoir belongs to micro-fracture pore style, which matches the dynamic production characteristics much better compared with "vuggy pore style" ever being thought to be. The well development of high-degree fracture and unbalanced development of reservoir properties makes it difficult to develop the reservoir. In order to make good use and develop the resources of Qian- Miqiao Buried-hill condensate gas reservoir effectively, and increase the producing reserves as well, reliable geologic model is built, reservoir engineer research is carried out, and favorable development areas has been found by applying the exiting data and combining the exploration research results, which explores a successful path for the effective development of buried-hill condensate reservoir.
