油田进入中、高含水期开发阶段,结垢情况日趋严重,从采油井、注水井到各个油水泵站、配水间以及地面的输液管线都存在不同的结垢现象,其中油井结垢尤为突出,严重影响原油产量和油井的检泵周期。本文对牛庄油田16队所管油井结垢的主要类型与成垢主要原因的进行了分析,并对油井结垢防治的主要方法进行了评价,提出了预防措施。
Oilfields enter the development phase of middle and high water cut stages, and scale formation is becoming more and more serious. There are different scale scaling phenomena in oil-water pumping stations, water distribution wells and ground infusion lines from oil production wells and water injection wells, of which oil well scaling is particularly prominent. Seriously affect the crude oil production and pump inspection pump cycle. In this paper, the main types of fouling of the wells controlled by Niuzhuang Oilfield Group 16 and the main causes of fouling were analyzed. The main methods of fouling prevention and control of the wells were also evaluated, and some preventive measures were put forward.
