Abstract

The pilot hole of CCSD-1 Well was started on June 25th, 2001, reached 2,046.54 m on April 15th, 2002. The largest deviation angle was only 4.1° and the largest dogleg angle 1.25° per 30 m, the quality of the well was good enough to satisfy the scheme of combining two wells into one. Reaming of the pilot hole on May 7th, 2002 actually signified the beginning of the main hole drilling. Experienced two times of expanding drilling, one time of straightening drilling by use of sidetracking, one time of sidetracking to avoid the obstacles and three phases of core drilling, the main hole reached 5118.2 m on January 23rd, 2005, and the task of coring was successfully fulfilled.
