Problems solved by technology
[0002] At present, oil production and oil collection methods in various oil fields are transported from oil wells to oil gathering stations or centralized processing stations by single-well pipelines. Due to the large temperature difference between the ground and underground, a large amount of wax will be precipitated soon after the crude oil is pumped out of the ground. It is attached to the inner wall of the oil pipeline, and if it is not cleaned for a few days, the oil pipeline will be blocked. Therefore, the oil production workers need to go to the well site every day to throw balls into the oil pipeline to remove wax and collect the balls regularly at the station. The ball collection device has undergone many improvements. Although It is a mature technology, but it has not got rid of the cumbersome manual operation. Every time the ball is collected, first open the valve of the bypass pipeline, then close the two valves before and after the ball collection device, and then release the pressure of the ball collection device section. Heating the wax, opening the quick-opening blind plate, and then taking the wax-removing ball out of the ball-collecting device also requires cumbersome operations to restore the ball-collecting state. In addition, the pipeline in the station needs to be purged regularly, which also requires cumbersome switching process operations

The invention relates to the field of oil field production and gathering equipment, in particular to a design method of a timed heating ball collecting device which is characterized by comprising two ball collecting blow-down double-function valves, an automatic ball collecting device, a control unit and a heating tape, wherein an upper ball collecting cylinder of the automatic ball collecting device is in series connected between crude oil output holes and crude oil input holes of the two ball collecting blow-down double-function valves by ball collecting pipes, the cylinder wall of the upper ball collecting cylinder is fixed with the heating tape, and blow-down holes of the two ball collecting blow-down double-function valves are communicated by blow-down by-pass pipes. The invention can complete all fussy operations during the ball-collecting and blow-down work by operating three valves, realizes ball collecting and blow-down integral control by utilizing the three special ball valves and matching automatic equipment, solves the fussy manual operation, can remove the corresponding valves and the by-pass pipes, and has obvious economic benefit.
