    Abstract：Gas reservoirs and production capacity of Jingbian Gas Field have damped rapidly after its development of over a decade. In order to ensure its steady output and production scale， studied and test was a surface gathering and transportation technology of commingled production for upper and lower Paleozoic gas reservoirs. The technology， including downhole throttling， series connection for single wells with low or middle pressure， no wellhead methanol injection and higher pressure ratio pressurization in gas gathering station， has realized low or middle pressure gas gathering and significantly reduced the degree of technical difficulties， operation pressure of surface system and surface construction investment. Meanwhile， its test and implementation will provide a brand new method and relevant technical support not only for ensuring steady production capacity of Jingbian Gas Field， but also for planning of the upper and lower Paleozoic gas reservoirs of 20×108m3/a and 10×108m3/a in southeast Sulige separately.
