青海油田千里气区保供“争气”

Core Insights - The natural gas demand in the Qaidam Basin has surged due to temperatures dropping to -18 degrees Celsius, prompting the Qinghai Oilfield to enhance gas production capacity to meet the needs of the Qinghai, Gansu, and Tibet regions [1] Group 1: Production Challenges and Solutions - The Qinghai gas fields face inherent geological challenges, increased water invasion, and inadequate process adaptability, leading to accelerated production decline [3] - The gas field has implemented a "control decline" strategy, focusing on enhancing natural gas production through specialized support teams and meticulous maintenance efforts, achieving a daily production decline control of 23,000 cubic meters [3] - The gas field has adopted sand and water treatment measures, increasing daily maintenance from 736 well times to 858 well times, with the Shabei gas field achieving a daily decline control of 20,000 cubic meters [3][4] Group 2: Technological Innovations - The gas field has made breakthroughs in low-pressure well production enhancement, achieving an increase in daily gas production from 236,000 cubic meters at the end of October to 629,000 cubic meters through the application of a new sand washing technology [4] - The gas field has implemented a large-scale application of a new technique involving 1.25-inch tubing and dual foam generators, achieving a sand washing efficiency of over 75% [4] Group 3: Operational Management - The gas field has established a specialized team for compressor management to address high failure rates and frequent shutdowns, ensuring compliance with operational management requirements to prevent unplanned outages [4] - The gas field has improved leak detection and response times, controlling pipeline leak repairs within four hours [4]
