目前,油田普遍存在一些低产低效井,尤其对一些高压低渗透油层,用抽油机进行机械采油,通常是入不敷出,亏本生产,封井一段时间后时常有原油喷出地面,造成不同程度的原油损失,因此,时常有不法分子破坏井口盗窃原油,轻则造成产能损失,重则造成环境污染。根据目前生产现实情况需要,设计并制作一种高效能套管封井器。有效起到了阻止不法分子盗窃原油、方便油井恢复和其他作业施工的作用,有效防范了环境污染的发生。
At present, some low-productivity and low-efficiency wells are commonly found in the oilfields. Especially for some high-pressure and low-permeability oil reservoirs, mechanical pumping with a pumping unit is usually unable to make ends meet and produces at a loss. Crude oil often spouts out of the ground after a period of closure, resulting in varying degrees Crude oil loss, therefore, from time to time criminals destroy the wellhead theft of crude oil, ranging from loss of productivity, heavy cause environmental pollution. According to the current production needs of the actual situation, design and production of a high-performance casing shut-off device. Effectively played a role in preventing criminals from stealing crude oil, facilitating well recovery and other construction operations, and effectively preventing the occurrence of environmental pollution.
