所谓空气洗井是指以压缩空气做为洗井介质的一种洗井方法。近年来，这种洗并方法有了很大发展，它对进一步促进钻探工艺的改进，设备的更新，效率和质量的提高，成本的下降，以及扩大钻探工程的使用范围等诸多方面，都起到了重要的促进作用，越来越得到人们的重视。为了更好地促进空气洗井技术的应用与推广，提高其使用中的科学性，现就空气洗井钻进时如何确定上返风速和供风量以及合理选用空压机问题，初步探讨如下，以供参考。
The so-called air flushing refers to a compressed air as a well washing medium washing method. In recent years, there has been a great development of this method of washing and washing, which has played a role in further enhancing the drilling process, upgrading equipment, improving efficiency and quality, reducing costs and expanding the use of drilling programs. To an important role in promoting more and more people’s attention. In order to better promote the application and promotion of airwashing technology and improve the scientificity in its use, the issue of how to determine the return air velocity and air supply when airwashing well and the reasonable selection of air compressors are discussed briefly. for reference.
