油田前7个月稠油产量同比增加1.3万吨

Group 1 - The core viewpoint of the articles highlights the steady increase in heavy oil production at Shengli Oilfield due to technological innovations and management optimizations, with a production of 2.64 million tons in the first seven months of the year, an increase of 13,000 tons compared to the same period last year [1][2] - The recovery of uncontrolled reserves has been a significant achievement, with the implementation of side drilling as a key strategy to restore these reserves, resulting in a capacity recovery of 225,000 tons through the deployment of 201 side drilling wells [1] - The focus on improving bottom well dryness has been emphasized as a decisive factor for efficient heavy oil development, with the bottom dryness level increased to 57.1% through various measures, including enhanced insulation and nitrogen continuous insulation technology trials [1] Group 2 - The oilfield has developed a ten-technology system for viscosity reduction and microbial development, successfully implementing 82 displacement well groups and 161 injection cycles in the first half of the year, leading to an additional oil production of 183,000 tons [2] - The focus for the second half of the year will be on solidifying the management of thermal recovery, iterating the promotion of MDGS technology, and tackling experimental composite displacement techniques to ensure a stable annual production benefit of over 4.5 million tons [2]
