Drilling Construction Technology of Well Qiping 3

Abstract:

Qiping 3 is a horizontal well in Qijia depression at central depression area of Songliao basin with slant depth of 3574.03m, vertical depth of 2201.1 m and horizontal section length of 1195.35 m while finishing drilling. Optimized designs were made on the casing program and well track section before the construction, and hole trajectory control and geo-steering as well as drilling safety construction technologies were applied during the construction to ensure the smooth operation and achieve the various technical indicators in the design with good effects.

Key words:horizontal well; well drilling; trajectory control; geo-steering; well Qiping 3
