低压漏失井填砂保护油气层技术探讨

Study of Sand Filling Hydrocarbon Reservoir Protection Technology in Low Voltage Absorption Well

油田在开发中需要进行调整,调整各层段时较多用到填砂这种工艺技术。低压漏失井填砂时,会有大量砂随携砂液进入地层,对地层造成染。分析了填砂时砂进入地层的原因,通过对可行保护措施进行分析结合实际应用情况,提出一种适合低压漏失井的填砂保护油气层技术。

The oilfleld development needs to be adjusted, more used sand filling. A lot of sand with the sand-carrying fluid into the formation, result to formation contaminant in sand filling of low voltage absorption well. Analysis feasible protection measures combined with the practical application of the situation, propose a suitable fill sand reservoir protection technology in low voltage absorption well.
