一、华北油田综合机械厂研制成功DWF-30型天然气发动机,经鉴定后已投入小批量生产。该机是利用抽油井的套管气,额定功率30马力,转速范围360～650转/分,燃气压力0.35～2.5公斤力/厘米~2,每小时耗气量10.63米~3。自1982年以来在某井带动一台5型抽油机,累计运转10033小时,运转正常,节电显著。二、江苏油田与武进柴油机厂协作,用295柴油机改制成T-22型天然气发动机,功率为22马力,每小时耗气仅4.85米~3,在试用中,除带一台5型抽油机外,还带动一台4瓩发电机,以供照明。三、中原油田运输公司在10台大客车上采用天
First, Huabei Oilfield Integrated Machinery Plant successfully developed DWF-30 natural gas engine, after identification has been put into small batch production. The machine is the use of casing gas pumping wells, rated power of 30 horsepower, speed range 360 ~ 650 rev / min, gas pressure 0.35 ~ 2.5 kg force / cm ~ 2, air consumption per hour 10.63 m ~ A well type 5 pumping unit has been driven in a well since 1982, accumulating 10033 hours of operation, operating normally and saving energy significantly. Second, Jiangsu Oilfield and Wujin Diesel Engine Factory collaboration, with 295 diesel engine into a T-22 natural gas engine, power of 22 horsepower, gas consumption per hour only 4.85 m ~ 3, in the trial, except with a 5-type pumping unit In addition, it also drives a 4 瓩 generator for illumination. Third, the Zhongyuan Oilfield Transportation Company in 10 buses using the day
