破解冬季稠油开发难题

Core Insights - The company has successfully implemented an innovative method using waste heat from electric pump wells to enhance the temperature of water used in oil extraction, resulting in a temperature increase of 23 degrees Celsius and saving 4,650 kilowatt-hours of electricity daily [1][2] Group 1: Innovation and Efficiency - The company has replaced the traditional water injection method with waste heat from electric pump wells, addressing winter production challenges in three heavy oil units and nine metering stations [1] - The new approach eliminates reliance on external water sources, reducing operational complexity and minimizing the risk of water injection failures due to equipment issues [1][2] Group 2: Operational Improvements - An independent internal water supply network has been established in heavy oil blocks, allowing high-temperature produced liquid to be transported via short pipelines, which has significantly reduced the frequency of pipeline freezing issues [2] - The modifications have led to a 50% reduction in operational manpower and have completed the transformation of 38 wells, with an average water injection temperature now stable at over 42 degrees Celsius [2]
