Development technology with thermal recovery for horizontal well of superheavyoil reservoir in Du 84 block in Shu 1 area, Liaohe Oilfield
Online published: 2011-12-20
Du 84 block is a super-heavy oil reservoir in the Shu 1 area, Liaohe Oilfield. When developed by the cyclic steamstimulation in vertical well patterns, the smaller drainage radius, lower oil production per period, lower oil rate per day, higher production decline rate and the inefficient displacement of the interwell remaining oil problems have been encountered. According to the study on the thermal recovery technology for horizontal well of super-heave oil reservoir, the deployment way of the horizontal wells, steam stimulation parameters and enhancing oil recovery with SAGD technology were analyzed. The result shows that the horizontal well development technology is a potential and advantageous new technology to relieve the contradictions between interlayer, endostratic and plane. Horizontal well steam stimulation and SAGD technology have more effectiveness than the vertical well, so the use of horizontal well is coming to be an effective method for enhancing oil recovery.
