克拉玛依砾岩油藏开发后期稳油控水综合治理研究

COMPREHENSIVE TREATMENT ON THE MATURED KARAMAY CONGLOMERATE RESERVOIR WITH THE MEASURES OF STABILIZING OIL PRODUCTION AND CONTROLLING WATER-CUT

克拉玛依砾岩油藏大都已进入中、高含水期开发阶段，油藏油、水分布日益复杂，挖潜难度增大。针对出现的问题，以“稳油控水”为目的，在开展油藏跟踪研究和油藏精细描述基础上，在一些区块因地制宜地完善注采系统，提高配套技术水平，加强经常性的调控管理，取得了较明显的效果。并指出了目前砾岩油藏存在的主要问题及需采取的对策。

Karamay conglomerate oil reservoir is a matured oil reservoir, and has already come into the high or moderate-high water cut stage. The oil and water distribution in the reservoir is now becoming more and more complicated day by day,so that it is very difficult for us to tap the potentiality of the reservoir for the purpose of stabilizing the oil-production and decreasing the water-cut within the produced liquid. As a result of this situation,many problems have happened at the present time,some technical measures have been adopted in some blocks of the matured conglomerate oil field,such as perfecting the present injection and production system,improving the matching technical level,frequently enhancing management and controling regulation,etc. Very successful effects were gained with all these measures. Finally the existing problems concerned with the conglomerate oil reservoir are summarized and the way to deal with these problems is also narrated in this paper.
