摘要
Abstract
As an advanced technology in ultra-heavy oil reservoirs development, SAGD drilling technology has been used in large scale both in China and abroad.Pilot test area was set up by Xinjiang Oilfield Company in 2008 and SAGD technology was tried for ultra-heavy oil reservoirs development in Zhong18 well area of Fengcheng oilfield with definite benefits.Based on the recent construction cases of horizontal producing well FHW117P and horizontal steam injection well FHW117I, the paper introduces the dual horizontal well drilling technology for SAGD.Tower type packed hole anti-deflection tool, mag-netic orientation technology and specific drilling fluid technology were the key in the dual horizontal well drilling construc-tion, through keeping lubricity of drilling fluid and putting downforce on screen pipe by circulative pressure device and large-weight drill collar,Φ177.8mm screen pipe was smoothly lowered intoΦ215.9mm borehole.关键词
