针对现场应用的测试防喷盒存在的井内液体易喷出或测试工具移动阻力大的缺点 ,研制了新型测试防喷盒。新型测试防喷盒在上部增设了一低压密封区及黄油盒 ,可以不必过于压紧盘根 ,并能自动给悬挂钢丝表面涂黄油 ,延长了盘根和钢丝的使用寿命。现场 50多口井的应用表明 ,新型测试防喷盒密封效果良好 ,作业时间减少了四分之一 ,密封件的使用寿命提高了 3倍 ,测试工作的可靠性增强。测试一口油水井能带来 2 0 0 0元的经济效益
In view of the field application of the anti-spray box there is easy to jet out of the well liquid or test tool to move the shortcomings of large resistance, developed a new test spray box. The new test box has a low-pressure sealing area and a butter box in the upper part. The packing can be pressed against the packing surface automatically, and the surface of the hanging wire can be automatically coated with butter to prolong the service life of the packing and wire. The application of more than 50 wells in the field shows that the new test box has a good sealing effect, a one-quarter reduction in working time, a threefold increase in the service life of the seal, and enhanced reliability of testing. Test an oil and water wells can bring 2,000 yuan of economic benefits
