在非均质油藏进入开发的中后期后,由于注水而存在的问题便会日益凸显。然而,油藏开发对于注水的要求也在日益提高。那么我们该怎么解决这一大难题呢?该怎样科学管理注水井,以水促油,提高水驱油效率,使油藏能够进入良性的开发状态呢?首先,我们需要牢牢记住“水井先行,油水并重”的思想,锁定注水问题的关键之处,分别从地面、井筒、地下这几个方面出发,全方位地提高注水管理水平,夯实油藏稳产基础。
After the heterogeneous reservoir into the development of the latter part of the problem due to water injection will become increasingly prominent. However, the demand for water injection in reservoir development is also on the rise. So how can we solve this big problem? How to scientifically manage the water injection well, promote the oil by water, improve the efficiency of water flooding and enable the reservoir to enter the healthy development state? First of all, we need to bear in mind that “ Wells first, oil and water both ”thinking, lock the key issue of water injection, respectively, from the ground, wellbore, underground these several aspects, all-round improvement of water injection management level, tamping the basis of reservoir stability.
