技术优化为油井“瘦身”增效

Core Insights - The article discusses the successful implementation of a simplified dual-pipe sand-carrying oil extraction process at the Shengli Oilfield, specifically at the Zhong31-Oblique B19 well, which achieved an average daily oil increase of 4.9 tons and a peak daily output of 8 tons over a stable production period of more than 50 days [1][2] Group 1: Technology and Process Improvement - The dual-pipe sand-carrying oil extraction technology enhances the efficiency of heavy oil wells by using dynamic liquid to lift oil and sand to the surface through high-speed circulation [1] - The optimized process integrates various stages such as sand-lifting equipment, sand discharge production, and oil-water treatment, which simplifies surface equipment and reduces energy consumption [1] Group 2: Economic Benefits - The Zhong31-Oblique B19 well saved 215,000 yuan in equipment costs by eliminating the need for a three-phase separation tank, transformer, and duty room, along with an additional savings of 41,400 yuan in personnel and electricity costs through optimized operations [2] - The annual savings per well is estimated at 250,000 yuan, with significant production efficiency improvements expected as 12 more wells are set to undergo similar process optimizations within the year [2] Group 3: Development Philosophy - The optimization work reflects the development philosophy of the Shengli Oilfield, which emphasizes "fewer wells, more control, high yield, and long-term effectiveness" in resource extraction [2] - The company plans to continue promoting high-quality and efficient new technologies and processes to drive robust development in the Shengli Oilfield [2]
