| 摘 要： | 欠平衡钻井是国际上20世纪90年代初再次兴起的提高勘探开发效益的钻井新技术。我国在总结以往经验教训的基础上，近几年来在油、气田勘探开发方面已经有一些单位进行了技术研究和现场试验，并取得了显著效益。在打开油气层后，如果钻井参数、钻井方式、钻井液性能等选择不当，会对生产层造成不必要的损害。通过研究钻井过程中对生产层的损害机理研究，表明欠平衡钻井对保护油气层是一种理想的钻井技术，对生产层的保护和开发具有重要现实意义。

| Abstract: | Unbalanced drilling,which sprung up once more in foreign countries in the early 1990's,is a new drilling technology to increase exploration and development benefits.On the basis of summarizing past drilling experience in China,some technical research and field testing are done in oil/gas field exploration and development respect in recent years,and outstanding economic benefits are obtained.When the oil/gas zone is opened,if the drilling parameters,drilling methods,drilling fluids performance are not properly chosen,it would cause unnecessary damage for the oil/gas zone.By studying the damage mechanism of the pay zone in the process of drilling,we obtain that unbalanced drilling is a perfect drilling technology to protect oil/gas zones,it is of important practical significance for pay zone's protection and exploration. |
