Mechanical thermal cleaning method for pipe poles in oilfield wellhead sites

Abstract

Disclosed is a mechanical thermal cleaning method for pipe poles in oilfield wellhead sites. The pipe poles are oil pipes and sucker rods. The mechanical thermal cleaning method is jointly realized by the aid of a pipe pole thermal cleaning device, auxiliary equipment, an oilfield wellhead site equipment overall arrangement mode and work procedures. The auxiliary equipment comprises a conveying rack, a retractable pipe gripping device and a conveying pulley, the oil pipes and the sucker rods can be cleaned by the same pipe pole thermal cleaning device, and side feed and side discharge of the pipe poles are realized. The pipe pole thermal cleaning device and the auxiliary equipment are reasonably arranged in an oilfield wellhead site, the pipe poles can be cleaned and repaired by the same machine in the oilfield wellhead site, conveying cost of the pipe poles is saved, automation level of workover treatment is improved, problems of high labor intensity of workers, poor cleaning quality, low thermal energy utilization rate, severe environmental pollution of the wellhead site and the like due to manual pipe pole cleaning in the oilfield wellhead site at present, and the like are resolved, and workover time is shortened.

Description

technical field [0001] The invention belongs to the technical field of cleaning oil well pipes and rods, in particular to a mechanical heat cleaning method for pipes and rods at the wellhead of an oil field. The pipes and rods mentioned in the method specifically refer to oil pipes and sucker rods. Background technique [0002] At present, the cleaning and repairing of oil pipes and sucker rods in major domestic oil fields is basically to pull the pipes and rods from the operation well site back to the pipe and rod repair base for cleaning, repair and reuse. The cost of transporting the pipes and rods back and forth is huge, especially for the ground The cost of transportation and cleaning of remote oil wells is even greater. For the convenience of description, the oil pipe and the sucker rod are combined and referred to as the pipe rod for short. The pipe rod includes both the oil pipe and the sucker rod. [0003] There are also examples of cleaning and repairing using the...

Problems solved by technology

[0007] In order to solve the above problems, the present invention provides a method for mechanical thermal cleaning of pipes and rods at the wellhead of an oil field. Part of the machinery used in the method is based on "an automatic high-efficiency oil pipe thermal cleaning device", and in "an automatic On the basis of the "high-efficiency oil pipe thermal cleaning device", partial transformation and installation have been carried out to make it a pipe rod thermal cleaning device. The pipe rod thermal cleaning device can not only clean the oil pipe but also clean the sucker rod. Side entry and side exit, and finally equipped with auxiliary equipment around the pipe and rod thermal cleaning device, the pipe and rod thermal cleaning device and auxiliary equipment are arranged at the wellhead site of the oil field through a reasonable layout, and the pipe rod can be cleaned on the same machine at the wellhead site of the oil field Repairing saves the transportation cost of pipes and rods, improves the automation level of workover operations, and solves the problems of labor intensity, poor cleaning quality, low heat energy utilization rate, and serious environmental pollution at the wellhead site caused by manual cleaning of pipes and rods at the oilfield wellhead site. and other problems, shortening the workover time
