摘　　要：ZY-I型井下不压井作业装置适用于机械采油或气举采油的深井和压力较高油井的井下作业。它与配套工具一起使用,具有坐封、脱丢手、解封和打捞以及排出压井液等多种功能。使用这种装置进行井下作业,不仅可节约大量压井液费用,防止油层污染,发挥油井正常生产能力,而且可提高抽油泵使用寿命。Model ZY-I downhole service equipment is suitable fordeep wells where mechanical production or air-lift produc-tion is adopted and for high-pressure wells. When used toge-ther with other mating tools, this equipment has the func-tions of setting on and off packers. fishing and letting outwell--killing liquids. This equipment can save much well-killing liquids, prevent formation contamination, ensure nor-mal oil delivery and elongate the service life of oilwellpumps.
