Abstract
Disclosed is a self-advancing high-pressure jet head for horizontal drilling, which comprises a shell, a plurality of drilling jet holes arranged on the shell, a cleaning jet hole and a water inlet. The front end of the shell is uniformly provided with three or six drilling jet holes, the side end thereof is uniformly provided with three or six cleaning jet holes, and the rear end thereof is opened with a straight hole water inlet. The utility model has the advantages of novel structure, reasonable design, easy manufacture and reliable work, with which the advancing force is generated by means of a jet counterforce to obtain the expanded hole, improve the cleaning and carrying capability of the rock debris and increase the drilling speed. The high-pressure jet head uses high-quality wear-resistant materials and is integrally machined, which can be applied in higher pressure environment, has the characteristic of self-advancing and long wear-resistant life and the like.
Description
Technical field:
The utility model relates to a kind of particularly boring means of super short radius horizontal drilling technology of oil drilling that is used for.
Background technology:
Horizontal drilling technology is the cutting edge technology of present oil drilling industry.The ultra-short radius horizontal drilling technology is to be used for finishing in the down-hole special tool(s) and the operational method of ultrashort radius horizontal hole by using.Its basic implementation method is in the vertical sleeve pipe well of preparation flatly, get out the bullport of required size at the desired location sleeve pipe with the radial aperture instrument, in the bullport that then special tool of high-pressure water jet radial horizontal drilling system is lowered to cased wellbores and is opened, ground high pressure pump truck injects high pressure drilling liquid in work string, and penetrate and the broken formation rock from the high-pressure injection head, realize the high-pressure water jet radial horizontal drilling, reach increase oil reservoir bare area, the underground oil field of high-efficiency mining.One of its key technology is to adopt the high-pressure injection head, relies on 50～70MPa high-pressure hydraulic to eject the eyelet of aperture 35～50mm.Chinese patent 97239624.1 has been introduced a kind of nozzle, under the high-pressure hydraulic effect, can spray aperture 60mm eyelet, but have only hydrophthalmia forward, be easy to generate very big reaction force backward, if use flexible pipe to send injection to, after reaching certain-length, the back is sent power to and can't be advanced shower nozzle to advance, or the ejection well is turned to, and can't form than diameter to well, influence spray penetration, and then influence construction effect.
The utility model content:
The purpose of this utility model is to provide a kind of can produce forward thrust, guarantee that the horizontal drilling of super short radius horizontal well smooth construction advances the high-pressure injection head with oneself.
The utility model is to realize like this.This kind high-pressure injection head is made up of housing and the water inlet and a plurality of spray-hole that are distributed on the housing, and the housing front end evenly has 3 or 6 and creeps into spray-hole, and side evenly has 3 or 6 and cleans spray-holes, and the rear portion has the straight hole water inlet.During work, ground high pressure pump truck injects high pressure drilling liquid in the underground work tubing string, and drilling fluid enters housing from the water inlet on this high-pressure injection head, respectively by creeping into spray-hole and please washing spray-hole and penetrate; The High-Pressure Water broken formation rock that creeps into the spray-hole generation of housing front end gets out the radial level well, and the cleaning spray-hole of housing side is gone out passage with landwaste.In said process, become the spray-hole that creeps at 7-15 degree angle to provide the place ahead eyelet to spray with the housing center line, become the cleaning spray-hole at 30-60 degree angle to pass through to oblique rear perforate hydrophthalmia with the housing center line, rely on spray reaction forces to produce the power of marching forward, enlarge well simultaneously, improve landwaste and clean and carrying capacity, improve rate of penetration, increase the oil reservoir jet length.
The utility model novel structure, reasonable in design, be easy to make, reliable operation utilizes it to rely on spray reaction forces to produce the power of marching forward, and can obtain to enlarge well, improve good construction effect such as landwaste cleaning, carrying capacity and drilling speed, this kind high-pressure injection head is selected the high-quality wear-resistant material for use, adopt whole processing, can be applicable under the higher pressure environment, have and to advance certainly and characteristics such as friction durability is long.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Fig. 2 is its A-A sectional drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is implemented to be illustrated.
As shown in the figure, the utility model is made up of housing 1 and a plurality of spray-hole 2, cleaning spray-hole 3 and the water inlets 4 of creeping into that are distributed on the housing 1.Wherein, housing 1 front end is a hemisphere, and middle part and rear portion are hollow cylinder, and periphery is provided with step, and the rear end is provided with pin thread.Creep into spray-hole 2 and be distributed on the housing 1 nose circle sphere, can be 3 or 6, its eyelet becomes 7-15 degree angle with center line.Clean spray-hole 3 and be distributed on housing 1 side, can be 3 or 6, its eyelet becomes 30-60 degree angle with center line.Water inlet 4 is opened at housing 1 rear portion, makes it to become the admission passage of drilling fluid.
Claims (1)
1. a horizontal drilling is with advancing the high-pressure injection head certainly, by housing (1) be distributed in a plurality of on the housing (1) and creep into spray-hole (2), clean spray-hole (3) and water inlets (4) are formed, it is characterized in that: housing (1) front end evenly has 3 or 6 and creeps into spray-hole (2), side evenly has 3 or 6 and cleans spray-hole (3), and the rear portion has straight hole water inlet (4).
