摘　　要：针对抽油机井作业起管柱过程中油管内井液外溢产生的环境污染问题,研制了提拉式泄油装置。装置由提拉式泄油器与旋转式管柱锚定装置共同构成,一次作业下完井管柱时将泄油器安装在泵上,锚定装置安装在泵下,通过旋转油管使管柱锚定装置坐封;二次作业起管柱时,上提管柱,泄油器与锚定装置依次解封,泄油器泄油孔漏出,使油套环空连通,实现泄油功能。室内实验与现场试验表明:泄油器承压性良好,不给油井正常生产增加隐患,锚定装置与泄油器解封性能可靠,能够成功实现泄油功能,并保障作业顺利进行。With the promulgation and implementation of the new environmental law, higher requirements for the well cleaning production have been put forward. Based on environmental pollution problems caused by well liquid overflow during pulling out the oil tubes, the lift-draw style oil drain device has been developed, which is composed of lift-draw style oil drain valve and the rotary style pipe string anchored. When the well-completion pipe-strings are put in the first down hole operations, the oil drain valve should be installed on the pump, the rotary style pipe string anchored should be installed under the pump. After putting the oil tubes, the lift-draw style oil drain device can be set down by rotating the oil tubes. When the oil tubes were pulled out in the second downhole operations, the sealing can be released by lifting oil tubes, oil drain valve and anchored device, the drain holes of oil drain device can be exposed, the annular space of tubing and casing pipe can be connected,the purpose of oil drainage can be achieved. Laboratory experiments and field tests show that pressure performance of oil drain valve is better, it doesn't increase hidden dangers to the normal production of oil wells,the seal-releasing performance of anchored device and oil drain valve is reliable, the function drainage can be successfully achieved, and it can ensure the operation smoothly.
