Abstract
A jet drilling spray nozzle comprises a spray nozzle body. A spray hole set is formed in the top of the spray nozzle body and comprises a plurality of jetting spray holes evenly distributed in the same circumference and obliquely arranged. The jet drilling spray nozzle is simple in structure and small in size, radial water conservancy jetting operation can be easily performed through an underground guiding tool, and the jet drilling spray nozzle can also be applied to cleaning and plugging a capillary tube. Due to the arranged spray hole set, spiral jetting is formed in a hole channel, the effects of forming striking breakage, shearing breakage and stretching breakage are formed, the rock breaking angle and the rock breaking range are increased, the rock breaking effect is improved, the reacting force in the axial direction is greatly reduced, and the self-advancing capacity of the spray nozzle is improved.
Description
Technical field
The present invention relates to a kind of petroleum industry field, specifically, is the jet drilling-well shower nozzle that a kind of radial direction well water conservancy is sprayed.
Background technology
The domestic and international shower nozzle for radial direction well is mainly straight fluid jet nozzle at present, it mainly breaks rock principle is impact grinding, this shower nozzle has good rock breaking efficiency in loose sand and weak seam, but be subject to the impact of geology composition and earth formation, this shower nozzle cannot obtain good injection rock breaking efficiency in hardpan and hard coal seam.
The self-rotating nozzle existed both at home and abroad at present, it mainly breaks rock principle is shear broken rock, the broken rock of strike and the broken rock of stretching, and self-rotating nozzle can reduce the threshold pressure of hydraulic drilling greatly, but current self-rotating nozzle exists more deficiency, shower nozzle length is oversize, cannot form turning in sleeve pipe, thrust is not enough, cannot be formed and effectively spray distance and drilling depth, easily rotation is lost after being hampered, even there is pressure release etc. problem, be also in theoretical research stage, cannot apply with radial direction well.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, devise a kind of jet drilling-well shower nozzle.
Jet drilling-well shower nozzle of the present invention, comprises head body, and described head body top is provided with spray orifice group, and described spray orifice group comprises and is distributed on the same multiple jet nozzles be circumferentially obliquely installed.
Preferably, described spray orifice group is provided with multiple with one heart, is arranged successively to circumference by the center of circle.
Preferably, each jet nozzle in described spray orifice group is identical with the angle between head body axis.
Preferably, the jet nozzle of adjacent orifices group is crisscross arranged.
Preferably, the top of described head body is hemispherical.
Preferably, in the middle part of described head body, outer wall is provided with V-ring groove, sidewall is provided with multiple downward-sloping rear spray orifice on the upside of described V-ring groove.
Preferably, described rear spray orifice is distributed on circumferentially same.
Preferably, on the upside of described V-ring groove, the gradient of sidewall is greater than the gradient of downside sidewall.
Preferably, described rear spray orifice is parallel with sidewall surfaces on the downside of V-ring groove.
The invention has the beneficial effects as follows: jet drilling-well shower nozzle structure is simple, and volume is little, easily carries out radial water conservancy spraying operation by Underwell guide tool, the cleaning of capillary tube can also be applied to and beat stifled.Produced by the spray orifice group arranged and form spiral jet in duct, form the effect of hitting broken, shearing-crushing and stretching fragmentation, add brokenly angle and the scope of rock, improve rock breaking efficiency, but also the reaction force greatly reduced on axis direction, what add shower nozzle enters ability certainly.
Spray orifice group arranges many groups, and multilayer is arranged, and improves rock breaking capacity, adds the internal diameter in the duct gone out simultaneously, make shower nozzle feed smoothly and to withdraw from.In spray orifice group, the angle of jet nozzle is identical, enables the jet ejected form uniform spiral jet, ensures perforating effect.The jet nozzle of adjacent orifices group is crisscross arranged, and the jet ejected is not interfere with each other, and increases the density of the rotating jet produced, improves rock breaking efficiency further.
The top of head body is hemispherical, is convenient to shower nozzle and feeds, and also guides to return the current spattered and discharge as early as possible simultaneously, reduces and returns the impact of spattering nozzle surface, improve the application life of shower nozzle.
Have spray orifice backward in the V-ring groove of head body, spray backward, in the process of creeping into, provide powerful propulsive force, improve the speed of punching further, reaming carried out to boring simultaneously and get rid of landwaste.Rear spray orifice is distributed on same circumference, makes the power that feeds that provides even, generation deflection in path when avoiding shower nozzle to advance.On the upside of V-ring groove, the gradient of sidewall is large, improves the angle that rear spray orifice sprays backward, can provide as much as possible and more feed power, also reduce the generation returned and spatter, and what also bootable perforation produced return spatters liquid and flow out as early as possible, raising perforation efficiency.Then spray orifice is parallel with sidewall surfaces on the downside of V-ring groove, then avoid jet and the head body surface contact of the ejection of rear spray orifice, prevent from rubbing between head body and jet, cause head body to wear and tear, ensure the shower nozzle life-span.
Accompanying drawing explanation
Accompanying drawing 1 is the perspective structure figure mono-of jet drilling-well shower nozzle;
Accompanying drawing 2 is the perspective structure figure bis-of jet drilling-well shower nozzle.
Detailed description of the invention
Jet drilling-well shower nozzle of the present invention, as shown in Fig. 1 to 2, comprises head body 1, and described head body 1 top is provided with spray orifice group 2.
Spray orifice group 2 comprises and is distributed on the same multiple jet nozzles 21 be circumferentially obliquely installed.Each jet nozzle 2 in spray orifice group 2 is identical with the angle between head body 1 axis
Spray orifice group 2 is provided with multiple with one heart, is arranged successively to circumference by the center of circle.The jet nozzle 21 of adjacent orifices group 2 is crisscross arranged.
The top of head body 1 is hemispherical.In the middle part of head body 1, outer wall is provided with V-ring groove 3.
On the upside of V-ring groove 3, sidewall 31 is provided with multiple downward-sloping rear spray orifice 4, rear spray orifice 4 is distributed on circumferentially same.
On the upside of V-ring groove 3, the gradient of sidewall 31 is greater than the gradient of downside sidewall 32, and rear spray orifice 4 is parallel with sidewall 32 surface on the downside of V-ring groove 3.
Suppressed on joint by the flexible pipe being threaded onto high-pressure injection hose end that is tightly connected that head body 1 is arranged by lower end, the high-pressure injection flexible pipe other end is connected with stainless steel coiled tubing, forms the downhole jetting tool string of radial hydraulic jetting drilling-well.
By the perforate on steering tool and down-hole casing, downhole jetting tool string is sent in stratum.Water under high pressure, by high-pressure injection flexible pipe and shower nozzle ejection, carries out radial hydraulic jetting drilling-well.
Water under high pressure enters into after in head body 1, and a part is sprayed forward by jet nozzle 21, and formation carries out brokenly rock.Due to the spread pattern of the jet nozzle 21 in spray orifice group 2, the jet of each spray orifice group 2 ejection is spiral jet, and form the effect of hitting broken, shearing-crushing and stretching fragmentation, rock breaking efficiency is strong; Another part water under high pressure is sprayed to oblique rear by rear spray orifice 4, by reaction force by shower nozzle and its downhole jetting tool string driven forward formed, be convenient to downhole jetting tool string advance forward while drilling well, also guided the water under high pressure after drilling well to return to spatter liquid and discharge.
