摘　　要：针对目前油田聚合物驱油中,对井内液体物性分析化验所使用的老式机械时钟取样器存在故障率高、成功率低、取样准确率低等问题,研制了新型密闭取样器。该取样器主要由电子线路板、控制阀杆、锥阀、取样筒、卸压锥阀、保护筒等组成,具有耐高温、耐高压、操作方便等特点。由电子时钟控制取样筒的打开时间,可准确获取井下预定深度的原始状态下的液体样品。现场试验表明,该取样器已达到设计指标要求,能够成功获取井筒中任意井段的样品,取样成功率达到100%。In light of the problem that,in current polymer flooding in oilfields,the old-fashioned mechanical clock sampler used in the physical and chemical analysis of the borehole liquid has a high failure rate,low success rate and low sampling accuracy rate,a new-type closed sampler is developed. This sampler mainly consists of the electronic circuit board,control valve lever,poppet valve,sampling thief,pressure-release poppet valve and protective barrel,characterized by high temperature and pressure resistance. Using the electronic clock to control the time to open the sampler,the liquid sample in its virgin state at the borehole predetermined depth can be obtained precisely. The field test shows that the sampler reaches the requirements of the design index,it can obtain the sample in any section of the wellbore,and the sampling success rate reaches 100 percent.
