摘要
针对塔河油田部分注水井失效问题,根据塔河油田的油藏性质和流体特征提出了注天然气提高原油采收率的方法,并且开展了稠油注天然气静态混溶室内实验研究,结果表明地层条件下塔河稠油注天然气混溶后降黏率可以达到80%,体积系数可以达到1.16,说明塔河油田稠油油藏天然气驱在原理上是可行的。
For the failure of some water injection wells in Tahe oilfield,according to the reservoir properties and fluid characteristics of Tahe oil field,the method of improving oil recovery by injecting natural gas is put forward,and the laboratory experimental study on the static mixing of heavy oil injection natural gas has been carried out. The results show that the viscosity reduction rate of Tahe heavy oil after mixing natural gas can reach 80 % and the volume coefficient can reach 1. 16.It shows that the principle of natural gas flooding in heavy oil reservoirs in Tahe oilfield is feasible.
