摘要

塔河油田强底水凝析气顶油藏是由气顶、油层及大底水组成的砂岩油气藏

在开发过程中

因气顶和底油采出不均衡

导致气窜或油窜

开发效果较差。针对塔河油田T区块块状底水气顶油藏的实际生产状况

综合考虑生产过程中气油比与密度的变化

探索了一种劈分气顶、油藏地面产量的新方法——单井生产阶段综合劈分法

应用此方法分别计算了气顶油藏的原油、凝析油、凝析气、溶解气的采收率

分别为12.28 %、22.96 %、29.75 %、12.05 %

将计算结果与国内外同类油气藏相比较

认为比较符合该类油藏的开发特点

而且现场操作较为简单。通过气顶油藏采收率的计算

了解气顶、油藏的开发状况

及时发现开发中存在的问题及区块的开发潜力

以便于更合理地开发气顶油藏。

Abstract

The strong bottom water condensate gas cap reservoirs in Tahe Oilfield is the sandstone reservoir composed of gas cap

oil reservoir and large scale of bottom water. In the process of development

gas channeling or oil channeling exists due to the uneven production of gas cap and bottom oil

and the development effect is poor. According to the actual production situation of gas cap reservoirs with massive bottom water in block T of Tahe oilfield

and considering the gas-oil ratio and density changes in the production process

a new method to split gas cap and reservoir ground production

integrated splitting method for single-well production stage

is explored. By this method

recovery rates of crude oil

condensate

condensate gas and dissolved gas in gas cap reservoirs are calculated

which are 12.28 %

22.96 %

29.75 % and 12.05 %

respectively. The calculated results are compared to that of the similar reservoirs at home and abroad

and it is found that they are matching the development characteristics of such reservoirs

and the field operation is relatively simple. Through the calculation of the oil recovery for the gas cap reservoirs

the development status is understood

and the problems existing in the development and the development potential of the block are timely discovered

so as to develop gas cap oil reservoir more reasonably.
