碳酸盐岩的油藏埋藏很深,而且储藏的类型和对应的空间具有多样化特征。缝洞型碳酸盐作为一种油藏的储集空间,但是由于它几乎没有储渗能力,所以也是其渗流的主要通道。很多油田受到油井含水量增加的影响,石油的出产量不断下降,为了解决这一问题,我们在实际的开采过程中,对含水量较高的油井采取了注水压锥的措施,并取得了显著效果。下面,笔者就将从注水压锥的基础理论出发,对如何更好地运用该技术进行具体讨论。
Carbonatite reservoirs are deep buried, and the types of reservoirs and corresponding spaces have diverse features. The fractured-cavity carbonate serves as a reservoir space for reservoirs, but it also serves as a major channel for its seepage because of its very little reservoir permeability. In order to solve this problem, many oilfields are affected by the increase of water content in oil wells. In order to solve this problem, we adopted the method of injecting water pressure coning on oil wells with high water content in the actual mining process and obtained Significant effect. Below, I will start from the basic theory of water pressure cone, on how to make better use of the technology for a specific discussion.
