摘要:

独立筛管防砂是当前油气井最常用的防砂方法之一。随着油气田开发的不断深入,独立筛管防砂系统所处的工作环境和自身条件发生变化,受高温高压、外部载荷、腐蚀、流体冲蚀等多种因素的影响,容易引发防砂失效,严重影响油气井的正常生产。结合长期矿场实践和理论分析可知,造成防砂失效的主要原因是防砂封隔器失效、密封机构失效、防砂筛管失效,其中防砂筛管失效是最主要原因,筛管冲蚀、筛管腐蚀、地质因素和特殊作业等是导致防砂筛管失效的主要因素。通过对油气井的防砂失效原因的深入分析,为油气井防砂工艺采取预防措施、避免防砂失效而影响生产提供了重要依据。

Abstract:

Standalone screen sand control method is one of the most commonly used sand control method for oil and gas wells. With the deepening of oil and gas field development, the working environment and its own conditions of the independent screen sand control system have changed. Affected by high temperature and high pressure, external load, corrosion, fluid erosion and other factors, it is easy to cause sand control failure, which seriously affects the normal production of oil and gas wells. In this paper, long?term mine practice and theoretical analysis are taken to investigate the reasons for sand control failure. It is considered that the main causes of sand control failure are sand control packer failure, sealing mechanism failure and sand control screen tube failure, among which sand control screen tube failure is the most likely to occur. Screen erosion, screen corrosion, geological factors and special operations are the main factors leading to the failure of sand control screen. Through the in?depth analysis of the causes of sand control failure in oil and gas wells, it provides an important basis for taking preventive measures to avoid sand control failure and affecting production.
