Abstract
The utility model provides a multifunctional hot washing valve, and belongs to wax removing tools for oilfield extracting well purpose. The multifunctional hot washing valve is composed of a valve body and a water nozzle, a channel is arranged in the position of a shoulder platform of the valve body, a short connecting pipe is arranged in the position of an entrance of the channel and is matched with the channel, the water nozzle is fixed on a short connecting pipe arranged at the outer end of the valve body, a valve seat is formed by the short connecting pipe arranged in the channel, a one-way valve is arranged on the valve seat, and a pressure spring arranged in the channel is fixed with the one-way valve. Compared with the prior art, the multifunctional hot washing valve is convenient to install, high in work reliability, prevented from potential safety hazards and long in service life, unneeded for other energy consumption, clean and thorough in wax removal, green and environment-friendly, wide in adaptability, applicable for all types of oil wells ( a rod pumping well, an electric pumping well, a gas lifting well and the like) and crude oil of any nature ( thin oil, thickened oil, high pour-point oil and the like ), repeatable in application, further capable of being used as a gas lifting valve, and capable of effectively prolonging the pump inspection period of an oil well and lowering oil extracting cost.
Description
Technical field
The utility model belongs to the oil well paraffin removal tool, is specifically related to a kind of multi-functional heated scrubing valve.
Background technology
Published heated scrubing valve, its weak point are that complex structure, heat resistance are poor, function singleness, the opening pressure amplitude of accommodation are little, the easy deformed damaged of critical piece, fault rate are high, easily leakage, application life are short.And use larger limitation is arranged, because pressure-bearing is low, only can be applied in the shallow well.
Summary of the invention
For the problems referred to above, the utility model provides that a kind of design is ingenious, simple in structure, component are few, easy assembling, but the paraffin-cleaning instrument that the reliable operation repair is reused, the scope of application is wide; Further comprehensive producing well hot-washing wax remover technique, solved that application life is short in existing this type of instrument, the leakage fault rate is high, well-flushing efficient is low, the wax removal weak effect, easily polluted reservoir, the pump work performance is had the shortcomings such as injury.
Multi-functional heated scrubing valve of the present utility model, to be consisted of by valve body and water nozzle, shoulder place at valve body is provided with passage, being provided with nipple in the entrance of passage matches with it, place on the nipple of outer end of valve body and be fixed with water nozzle, place the valve seat of the nipple formation one way valve in the passage, one-way valve seat has compression spring and one way valve to fix in passage on valve seat.
The multi-functional heated scrubing valve of the utility model is the downhole tool of hot-washing wax remover process matching, has the several functions such as heated scrubing valve, gas lift valve.The pressure that this instrument provides when relying on heat to wash operation is opened the pressure switch of this heated scrubing valve, finishes the wax removal operation, thoroughly removes oil pipe (bar) wax deposition; Can also release simultaneously bushing gas, realize gaslift.Be that a kind of simple in structure, wax removal is clean thoroughly, reliable operation is steady, need not safeguard, the paraffin removal tool that repeats to assemble use of relative low price.
The multi-functional heated scrubing valve of the utility model compared with prior art has easy for installation; Functional reliability is high, do not have potential safety hazard, long service life; Need not other energy consumption, wax removal is clean thoroughly, environmental protection; Wide adaptability is applicable to the oil well of any type (pumping well with pole, electric pump well, gas-lift well etc.) and the crude oil of any character (thin oil, viscous crude, high solidifying wet goods), but repeated application; Can also use as gas lift valve; Effectively Extended Pump Detection Period reduces cost for oil production.
Description of drawings
Fig. 1 is multi-functional heated scrubing valve structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, multi-functional heated scrubing valve of the present utility model, to be consisted of by valve body 1 and water nozzle 2, shoulder place at valve body 1 is provided with passage 3, be provided with nipple 7 in the entrance of passage 3 and match with it, place on the nipple 7 of outer end of valve body 1 and be fixed with water nozzle 2, place nipples 7 in the passage 3 to form the valve seat 6 of one way valves 5,5 on one way valve has compression spring 4 and one way valve 5 to fix in passage 3 on valve seat 6.This apparatus multifunction heated scrubing valve, its component are machined piece, part is standard component, and assembling is simple, interchangeability is strong; Parts wear, distortion are reused after replaceable.Can form above three parts in ground-mounted during use, the use of then going into the well during underground work does not have the stress weak spot, do not affect tubing string connection, seal and pass through performance; That use has is high temperature resistant, the characteristics of reliable operation, fault rate.
