Abstract
A kind of directional hole direct-insert nozzle, belongs to oil exploration equipment field.The purpose of this utility model is to provide a kind of directional hole direct-insert nozzle that jetting fluid is made into the husky husky injection conditions of applicable water that mixes rear design of water.Tungsten steel alloy shower nozzle of the present utility model and steel tube connector, in edge seam, have straight spout and the oblique spout that becomes 30 degree angles with straight spout at shower nozzle front end; Be provided with contra-injection hole at edge reverse side, the tube connector place of the outlet correspondence in contra-injection hole is provided with the husky platform of trapezoidal anti-collection, has reflection discharge orifice at trapezoidal anti-collection Sha Taishang.The utility model is simple in structure, sprays great efforts, due to by having added 70 order fine sands in jetting fluid, so original shower nozzle cannot adapt to, thus design shower nozzle of the present utility model, even if geology more firmly due to fusion fine sand, also can be outputed oil pumping mouthful easily.
Description
Technical field
The utility model belongs to oil exploration equipment field.
Background technology
Oil exploitation at present needs jet drilling technology, carry out opening several oil pumping mouths more in order to improve oil recovery and design, what spraying equipment ejected is water, injector head is that front end has spray-hole, and rear end has reflection spray-hole, and this kind of injector head is in the time running into compared with hard place matter, be difficult to eject direct route according to pre-program, so, substantially just can not increase oil pumping mouthful at harder geological condition, have a strong impact on operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of directional hole direct-insert nozzle that jetting fluid is made into the husky husky injection conditions of applicable water that mixes rear design of water.
Tungsten steel alloy shower nozzle of the present utility model and steel tube connector, in edge seam, have straight spout and the oblique spout that becomes 30 degree angles with straight spout at shower nozzle front end; Be provided with contra-injection hole at edge reverse side, the tube connector place of the outlet correspondence in contra-injection hole is provided with the husky platform of trapezoidal anti-collection, has reflection discharge orifice at trapezoidal anti-collection Sha Taishang.
The utility model is simple in structure, sprays great efforts, due to by having added 70 order fine sands in jetting fluid, so original shower nozzle cannot adapt to, thus design shower nozzle of the present utility model, even if geology more firmly due to fusion fine sand, also can be outputed oil pumping mouthful easily.
brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is A part enlarged drawing in the utility model Fig. 1;
Fig. 3 is the utility model transmitting head piece and the husky platform part-structure of trapezoidal anti-collection sectional view.
Detailed description of the invention
Tungsten steel alloy shower nozzle of the present utility model 4 with steel tube connector 1 in edge 7 places seam, shower nozzle 4 front ends have straight spout 5 with the oblique spout 6 at 5 one-tenth 30 degree angles of straight spout; At edge, 7 reverse side are provided with contra-injection hole 3, and tube connector 1 place of the outlet correspondence in contra-injection hole 3 is provided with the husky platform 2 of trapezoidal anti-collection, have reflection discharge orifice 8 on the husky platform 2 of trapezoidal anti-collection.
Edge is arranged on steel tube connector 1, a little more than the external diameter of steel tube connector 1.
Owing to having added 70 order fine sands in water, thus larger to spray-hole wearing and tearing, therefore make shower nozzle into tungsten steel alloy, gain in strength.
Straight spout is generally that open in whole shower nozzle axle center, and tiltedly spout is around straight spout surrounding, and tiltedly the axle center of spout becomes 30 degree angles with the axle center of straight spout.
The husky mixed liquor of water sprays from contra-injection hole, be subject to geology to affect very easily fine sand retroeflection to enter in contra-injection hole, cause contra-injection hole plug, so just do not have due effect, so, a husky platform of trapezoidal anti-collection is set in position corresponding to contra-injection hole exits place, in the time of the husky mixed liquor ejection of water, is sprayed power effect, change and flow to through trapezoidal slope, like this, reflux even if produce, also can directly not impact contra-injection hole.
Finally, the husky mixed liquor of water is by the ejection of reflection discharge orifice.
Claims (1)
1. a directional hole direct-insert nozzle, is characterized in that: tungsten steel alloy shower nozzle (4) and steel tube connector (1) at edge (7) locate seam, have straight spout (5) and become the 30 oblique spouts (6) of spending angles with straight spout (5) at shower nozzle (4) front end; At edge, (7) reverse side is provided with contra-injection hole (3), and the tube connector (1) of the outlet correspondence of contra-injection hole (3) locates to be provided with the husky platform of trapezoidal anti-collection (2), has reflection discharge orifice (8) on the husky platform of trapezoidal anti-collection (2).
