井筒完整性检测与评价技术在致密储层的应用

Application of wellbore integrity detection and evaluation technology in tight reservoir

随着油气井和注水井长期生产运行,极大增加了井下管柱漏失风险,早期的微小泄露可能逐渐加剧,给井筒和生产安全带来严重隐患。井筒完整性检测与评价技术,成为井筒漏失检测和漏点定位的重要手段。通过对井温、流量、管柱腐蚀、流动噪声等多参数组合测量和综合分析,能较好对井筒内漏失情况进行定性分析。

With the long-term production and operation of oil and gas Wells and water injection Wells,greatly increases the risk of leakage of downhole string.the small leakage in the early stage may gradually aggravate,bringing serious hidden danger to wellbore and production safety.The wellbore integrity detection and evaluation technology has become an important means of wellbore leak detection and leak location.Through the combination measurement and comprehensive analysis of multiple parameters,such as well temperature,flow rate,pipe string corrosion,flow noise.the leakage situation in the wellbore can be qualitatively analyzed.
