Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention will be further described: as figure 1 , figure 2 , image 3 , Figure 4 As shown, the invention includes: a lifter 9, a supporter 12 hydraulic tongs 15 constitute a complete technical solution. The specific implementation process is: first install and connect before the operation of lifting and lowering the oil pipe. The wireless remote control station is installed in the operating room 2, and the handheld remote control is loaded with batteries. Storage battery 29 and wireless receiver a30 are packed in the lifter 9, then lifter 9 is connected with traveling tackle 7 with ring 8. Connect the flange on the hydraulic tongs support 14 to the wellhead, connect the oil inlet and outlet of the hydraulic pump on the workover rig 1 to the inlet and outlet of the hydraulic distributor on the hydraulic tongs. Connect two pipelines from the hydraulic distributor 16 and connect with the two hydraulic cyli...

The invention discloses a method for tripping an oil pipe in oil field workover operation, and belongs to a device and method for tripping an oil pipe in an oil well, a water well and a gas well. Thedevice and method solve the problems that when the oil pipe tripping process is carried out in oil field workover operation at present, the oil pipe is tripped mostly by adopting two traditional oil pipe lifting clamps and being lifted by a manual lifting repeated alternating method; hydraulic tongs are also hoisted on a derrick, and are manually pushed and pulled and reversed; and the present conditions severely restrict the progress in this field, personal injury is caused to employees and poisoning is also caused to workers due to long-term exposure to toxic gases. Therefore, the problems need to be solved urgently by replacing the previous manual oil pipe tripping method with a new unmanned oil pipe tripping method. According to the device and method, a lifter 9, a supporter 12 and hydraulic tongs 15 constitute a complete technical scheme. A wireless remote control technology is adopted to remotely control the lifter 9, the supporter 12 and the hydraulic tongs 15, so that no manualoperation of a wellhead is achieved. A completely different method for tripping the oil pipe from the prior art is realized. The method is simple to operate, completely eradicates personal injury toconstruction personnel, improves safety guarantee and realizes no manual operation of the wellhead.
Description
technical field [0001] The invention relates to a method for lifting and lowering oil pipes during workover operations in oil fields, and belongs to devices and methods for lifting and lowering oil pipes in oil wells, water wells and gas wells. Background technique [0002] At present, in oil field workover operations, most of the traditional two tubing elevators are used in the process of lifting and lowering the tubing, and the tubing is lifted and lowered by manual lifting repeatedly and alternately. Some adopt the method that the wellhead is equipped with a lock disc, but the lock disc adopts slips to block the tubing body, which will cause damage to the tubing. In addition, the hydraulic tongs are still hoisted on the derrick, and manually pushed and pulled and reversed. These current conditions seriously restrict the progress in this field, which will cause personal injury to practitioners and poisoning to workers due to long-term exposure to toxic gases. Therefore, ...
