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.
