Analysis and prevention of oil well casing damage
油井套管损坏分析与防治研究

摘要

在油田生产的过程中，油井套管损坏情况较多，其损坏的因素很多，主要的因素有：生产技术因素、固井质量因素、套管材料因素、油气储藏特征因素以及地层特征因素等。如果油井套管损坏，一方面将对油井的产量产生严重影响，另外，油井套管损坏还对油井网络造成破坏，会破坏影响整个油田的生产。本文对油气井套管损坏的原因及预防措施进行研究，进而找出油田油气井套管损坏的机理，制定出油田采油最佳方案及制定出相应油气井套管损坏防止体系，从而达到提升油田采油、采气的效率，最终为增加油田产量提供理论与技术依据。

Abstract

In the process of oilfield production, there are many cases of casing damage in oil wells, and there are many factors that can cause damage. The main factors include production technology, cementing quality, casing material, oil and gas storage characteristics, and formation characteristics. If the oil well casing is damaged, it will not only have a serious impact on the production of the oil well, but also cause damage to the oil well network, which will affect the production of the entire oil field. This article studies the causes and preventive measures of casing damage in oil and gas wells, in order to identify the mechanism of casing damage in oil and gas wells, develop the best oil recovery plan for oil fields, and establish a corresponding prevention system for casing damage in oil and gas wells. The goal is to improve the efficiency of oil and gas production in oil fields and ultimately provide theoretical and technical basis for increasing oil and gas production.
