摘要
Abstract
In directional drilling, non-magnetic PDM drill is developed both in China and abroad to achieve effective trajec-tory control.The structure characteristics and working principle of non-magnetic PDM drill are introduced.The performance tests were done on 2 non-magnetic PDM drills made both in China and abroad, by the comparison between the feature differences of these non-magnetic different PDM drills and the further understanding of the performance characteristics, the basis for field application and selection are obtained.关键词
