油田注水开发一段时期以后,为适应油藏动态变化、改善开发效果、稳定油田产量、提高采油速度,要进行适当地加密调整、补钻一批新井。因此,合理确定调整井数,以保障获得最大经济效益是人们所关注的问题。 前人在这方面已做过有益探讨,本文在这一启发下,认为:加密调整一般是在油田开发中、后期进行的,补钻的新井产能和累积产油量比老井要低得多;据克拉玛依油田开发经验,在不发生井网干扰的条件下,调整井一般可稳产1—2年,之后与老井按
After a period of oilfield waterflood development, in order to adapt to the dynamic changes of reservoirs, improve the development effect, stabilize the output of oilfields and increase the oil recovery rate, appropriate new drilling and drilling should be carried out. Therefore, it is a matter of concern that a reasonable determination of the number of wells to ensure the maximum economic benefits. The predecessors have done a useful discussion in this respect. Based on this enlightenment, this article argues that: Encryption adjustment is generally carried out in the oilfield development in the late period, and the new well production and cumulative oil production of make-up drilling are much lower than that of the old well ; According to Karamay oilfield development experience, in the absence of well network interference conditions, the adjustment wells generally stable production 1-2 years, then with the old well press
