Abstract
The utility model relates to a hydraulic cutting seam deep penetration high pressure jet gun nozzle for petroleum production well, which resolves the problems of short service life and low service efficiency of the existing high pressure hydraulic nozzles; the utility model is characterized in that the inner wall on the side of the liquid inlet of a nozzle (1) is a smooth round cambered surface (2) protruding outward; the inner wall of the through hole of the nozzle (1) is provided with wear-resistant paint coating. The nozzle has the advantages of long service life and high service efficiency.
Description
Technical field:
The utility model relates to the accessory on oil recovery field, the oil field PetroChina Company Limited. producing well hydraulic slotted liner technique deep penetration high-pressure spray gun, especially Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle.
Background technology:
Latter period of oilfield development be to excavate the crude oil of thin poor reservoir non-producing reserves, conventional perforating technology can't perforation the well section, use high-pressure hydraulic slot deep penetration technology that sleeve pipe is carried out the jetting slot, set up gas channel.The necessary accurately location of instrument of waterpower cutting is delivered usually in the degree of depth of down-hole hundreds of rice even several kms in the position of cutting, requires the slot configuration rule, and the degree of depth of earth penetrating is greater than 1.5 meters.And the wolfram steel high-pressure hydraulic nozzle that uses at present is because structural reason, working life is short, service efficiency is low, after 10 slots of undercut, nozzle will change shape and physical dimension under the effect that contains the sand jet of 60-70Mpa, just the inlet side at nozzle produces eddy current and damages inlet end face and nozzle inner walls, and the jet pressure that nozzle is ejected can not reach required pressure, must change nozzle.
The utility model content:
In order to overcome the deficiency that the existing high-pressure hydraulic nozzle operation life-span is short and service efficiency is low, the utility model provides a kind of Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle, and this Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle has long working life and the high characteristics of service efficiency.
The technical solution of the utility model is: this Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle comprises nozzle body, and nozzle body inlet end inwall is the arc surface of the outside slyness of protruding, and the through-hole wall of nozzle body has wear-resistant paint coating.
The thickness of above-mentioned coating is 1～2mm.
The utlity model has following beneficial effect: owing to take such scheme, nozzle body inlet end inwall is the arc surface of the outside slyness of protruding, inlet side at nozzle body when from then on water under high pressure enters in the nozzle body can not produce eddy current, avoid of the damage of high pressure eddy current to nozzle body entrance point inwall, simultaneously because the through-hole wall of nozzle body has wear-resistant paint coating, avoided the damage of High-Pressure Water to the through-hole wall of nozzle body, draw after tested, this nozzle is compared case hardness with existing like product increased 3-5 doubly, the construction power consumption reduces by 10%, one this nozzle of cover can be finished the cutting of 20-30 bar seam, thereby this nozzle has long working life, use it to increase work efficiency, reduce cost.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-nozzle body among the figure, 2-arc surface, 3-coating.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle, comprise nozzle body 1, nozzle body 1 inlet end inwall is the arc surface 2 of the outside slyness of protruding, this arc surface 2 is the rounding off face with the straight hole of nozzle body 1, can not produce eddy current at arc surface 2 places and with the joint of straight hole like this, and then avoid of the damage of high pressure eddy current nozzle body 1 entrance point inwall; The through-hole wall of nozzle body 1 has wear-resistant paint coating 3, the thickness of coating 3 is 1～2mm, coating 3 has been avoided the damage of High-Pressure Water to the through-hole wall of nozzle body 1, draw after tested, this nozzle is compared case hardness with existing like product increased 3-5 doubly, and the construction power consumption reduces by 10%, one this nozzle of cover can be finished the cutting of 20-30 bar seam, thereby this nozzle has long working life, uses it to increase work efficiency, and reduces cost.
Claims (2)
1, a kind of Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle, comprise nozzle body (1), it is characterized in that: nozzle body (1) inlet end inwall is the arc surface (2) of the outside slyness of protruding, and the through-hole wall of nozzle body (1) has wear-resistant paint coating (3).
2, Petroleum Production well water power slot deep penetration high-pressure spray gun nozzle according to claim 1, it is characterized in that: the thickness of coating (3) is 1～2mm.
