| Abstract:After researched on long distance trechless pilot drilling in certain project under complicated space conditions in Changsha, the author suggested that the information about underground pipe lines and other structures should be collected as completely as possible while engineering under similar conditions, that the pilot borehole trajectory should be reasonably designed based on space conditions, that drilling mud should be prepared and mud additives should be reasonablely selected and that pipe drawing assembly should be suited to long distance pipe drawing. |
