利用水平井进行出砂冷采是开采重油油藏行之有效的方法之一,但随着开采的进行,容易出现油井产量递减较快的问题,冷采稳产难度加大。为了达到稳产、提高采收率的目的,本文以实际油藏参数建立了油藏数值模拟模型,利用数值模拟方法在原水平井井网的基础上模拟了六种不同加密方案的生产效果,通过影响因素分析及经济评价确定了最优加密方案,对该区块以及出现此类问题的油田提供了一定的参考依据。
It is one of the effective methods to exploit heavy oil reservoirs that the horizontal well is used for sand production and cold storage. However, with the progress of mining, the output of oil wells tends to decrease rapidly, making it more and more difficult to cool and steady production. In order to achieve stable production and enhanced oil recovery, a reservoir numerical simulation model was established based on the actual reservoir parameters. The numerical simulation method was used to simulate the production effects of six different encryption schemes on the basis of the original horizontal well pattern. Factor analysis and economic evaluation to determine the optimal encryption scheme, the block and the oil field appears to provide some reference for such problems.
