针对间喷井或补孔后有溢流井,一般都采取压井作业。在压井作业中,洗井液易进入地层造成油层的污染和损害。采取不压井作业是保护油气层的重要措施之一。不压井作业一方面可以省去用于压井作业的压井液及其处理费用;另一方面,由于油气层得到了很好的保护,油气层的产能会得到相应的提高,从而可以最大限度的利用我们地下的油气资源。文南油田目前研制应用的防喷泵工艺技术能够很好的解决此类问题。 For inter-injection or after-fill overflow wells, are generally taken to kill operations. In the well killing operation, the flushing fluid easily enters the formation to cause the pollution and damage of the oil layer. One of the important measures to protect the oil and gas layer is to take the non-well operation. On the other hand, due to the well protected oil and gas reservoirs, the production capacity of the oil and gas layers can be increased correspondingly so as to maximize the cost of well killing operations Limit the use of our underground oil and gas resources. The anti-jet pump technology developed and applied in Wennan Oilfield can solve such problems well.
