The utility model has the effect of realization of timing ball injecting and manual remotely controlled ball injecting, thereby enabling the ball-loading operation easy, simple and convenient, reducing the labor intensity of workers, and improving the security of the ball injecting operation; and the plunger piston sealing realizes that seal can prevent raw oil from entering the ball storage cylinder, thereby causing the ball storage cylinder to be in the normal pressure working state, and overcoming the deficiency of emptying and pressure-release of common manual ball injecting or rotary electrically operated valve automatic ball injecting.
Description
Technical field
The utility model relates to crude oil pipeline conveying technology field, the ball-throwing apparatus of particularly a kind of petroleum pipeline inwall wax removal, desilting or de-plugging.Be a kind of, throw in spherical pig in the time of also being applied to oil-field flooding pipeline descaling and blockage relieving or chemical pipeline desilting drag reduction at oilfield well head ball-throwing apparatus.
Background technology
After waxy crude oil is lifted to ground, be subjected to the variation of conditions such as temperature, pressure, the gathering line wax deposition is separated out, and sticks on the tube wall, causes the gathering line negotiability to descend rapidly, and Oil Well Back Pressure rises, even blocking pipeline, influences the oil well ordinary production.Need this moment to send spherical pig (pitching) from uphole end, remove things such as wax deposition that its inwall adheres to, dirt, the holding tube line overcurrent is smooth and easy, saves power source, normally moves to guarantee follow-up flow process and equipment.
Gathering line pitching wax removal technology develops into semi-automatic or automatic ball-throwing technology such as the pitching of mobile ball basket formula, spiral half forced action type, the pitching of row's chain drive-type, rotary electric ball-valve type gradually from initial artificial pitching.But all there is many disadvantages in above technology, causes the automatic ball-throwing technology always can't be in the oil field large scale application.
Artificial pitching of crude oil gathering pipelines or existing automatic ball-throwing apparatus must be opened valve when pitching is operated, there is potential safety hazard like this in the pressure release of emptying draining, and cause the crude oil problems such as contaminated equipment, atmosphere, workplace that leak easily.
Present domestic oil field begin one's study the test the automatic ball-throwing mode be rotary electric ball valve stuff.This know-why is by automatic control actuating motor, and the rotation implement device that drives the ball core is served a ball automatically.This device is simple to operation, and pitching is reliable and stable, good seal.Shortcoming is: necessary electromotor is big and heavy, and inconvenience is installed; Storage bulb palpus energy consumption for keeping temperature is big; Need pipeline emptying, pressure release during the dress ball, discharge crude oil in the dress ball tube, can not satisfy the HSE management expectancy of oilfield enterprise's development; Cost is higher, is not easy to apply on a large scale.
The utility model content
The purpose of this utility model is: a kind of normal pressure dress ball self-sealing sealing ball-throwing apparatus is provided, realize regular automatic ball-throwing of well mouth of oil well or Long-distance Control automatic ball-throwing pigging, alleviate labor strength, reduce the recruitment total amount, realize the well site unmanned, establish technical foundation for advancing field produces operation and control automation.
The technical solution adopted in the utility model is: normal pressure dress ball self-sealing sealing ball-throwing apparatus, mainly form by controller, electrical header, turbine and worm, plunger case, connecting rod, ball storage barrel and plunger.It is characterized in that: horizontal fixed has plunger case on base, and plunger and connecting rod are arranged in the plunger case.One end of plunger connects connecting rod, and connecting rod promotes plunger and moves back and forth.The other end of connecting rod is connected with turbine and worm, and the turbine and worm reducing gear is fixed on the end of plunger case, is connected with electrical header and controller with the turbine and worm reducing gear.Middle part and vertical column plug cylinder at plunger case are fixed with a ball storage barrel, and ball storage barrel is communicated with plunger case.The other end of plunger case is connected with gathering line is vertical.Plunger case is communicated with gathering line.
Can not roll back backward for a spherical pig that makes plunger move back and forth release at every turn, between plunger case and gathering line, be connected with the pitching transmitter, be fixed with elasticity non-return shift fork in the pitching transmitter.
The operating principle of normal pressure dress ball self-sealing sealing ball-throwing apparatus: consult Fig. 1. when the gathering line pitching, controller 1 sends electronic execution signal, electrical header 2 actions drive turbine and worm 3 rotations, plunger case 4 horizontal slips, plunger case 4 drivening rods 5, plunger 8 move horizontally to the opposite direction of pitching transmitter 9, when plunger 8 moved to precalculated position, ball storage barrel 6 lower left, spherical pig 7 fell (the next ball that once only can fall is controlled in design) by deadweight in the ball storage barrel 6; Electronic then execution signal controlling plunger 8 continues to the pitching Transmitter side to promotion, impetus by plunger 8, a spherical pig 7 of plunger front is sent into pitching transmitter 9, this spherical pig 7 is pushed elasticity non-return shift fork 10 open after entering pitching transmitter 9, spherical pig 7 continues to move ahead and promotes the spherical pig 7 in front and enters gathering line 11, finish a pitching operation. the main effect of elasticity non-return shift fork 10 is to prevent that spherical pig 7 from returning with the travelling backwards of plunger 8. during The field, can set the pitching time interval according to the requirement of production scene, the timing automatic ball-throwing signal is set, realizes the pitching of on-the-spot unmanned self-timing.
The beneficial effects of the utility model: the utility model normal pressure dress ball self-sealing sealing ball-throwing apparatus, can realize regularly pitching or artificial Long-distance Control pitching, it is easily easy that the dress ball exercise is done, and alleviated working strength of workers, improves the safety of pitching operation.Plunger seal realizes that sealing stops crude oil to enter ball storage barrel, guarantees that ball storage barrel is the normal pressure duty.The deficiency of emptying pressure release when having overcome conventional artificial or rotary electric valve automatic ball-throwing.Be adapted at the oil field large scale application.
