在分析下二门油田井漏原因的基础上 ,制定了安全钻井的防漏堵漏工艺技术措施 ,并且强调要以防为主、防堵结合。现场应用表明 ,该防漏堵漏技术能明显减少井漏次数 ,并能快速有效地堵住漏层 ,从而减少了经济损失 ,保护了油气层。 Based on the analysis of the causes of the leakage in Xiaermen Oilfield, the technical measures for preventing leaks and plugging in safety drilling are formulated, and the prevention and the prevention are combined with the prevention measures. The field application shows that the leakage prevention technology can significantly reduce the number of lost circulation, and can quickly and effectively block the leakage layer, thus reducing economic losses and protecting the oil and gas layers.
