油水井出砂是石油开发中遇到的重要问题之一,每年要花费大量人力物力进行研究和防治。因为砂害得不到治理,油水井出砂会越来越严重,油气田就不能有效地开发。一、油水井出砂的危害出砂的危害主要有以下四方面:1.减产或停产作业。2.地面和井下设备磨蚀。3.套管损坏、油井报废。4.地层砂产出井筒,对环境造成污染。二、冲砂工艺现状2.1冲砂简介冲砂就是指向油水井内高速注入流体,靠水力作用将井底沉
Oil and water well sand production is one of the important problems encountered in oil development, each year to spend a lot of manpower and resources for research and prevention. Because sand can not be harnessed, oil and sand wells will be more and more serious, and oil and gas fields can not be effectively developed. First, the damage of oil and sand wells sand The main hazards of sand are the following four aspects: 1. Cut or stop production operations. Ground and downhole equipment abrasion. 3 casing damage, oil wells scrapped. 4. Formation sand production wellbore, causing pollution to the environment. Second, the current status of red sand 2.1 Introduction to red sand red sand is the injection of oil and water injection wells at high speed, by hydraulic action will sink
