Abstract
The utility model relates to an efficient zero-slips-bite drill rod for improving the hydraulic efficiency. The efficient zero-slips-bite drilling rod comprises a drill rod female joint and a drill rod male joint, wherein an anti-slips-collapse section with an anti-slips-collapse section spiral groove is connected to the inner end of the drill rod female joint; a male joint hydraulic cleaning end with a male joint hydraulic cleaning end spiral groove is connected to the inner end of the drill rod male joint. According to the efficient zero-slips-bite drill rod, the technical problems that drilling fluid density, drilling parameters and even a well structure are required to be changed due to poor sand carrying capacity of slurry in the drilling process through an existing zero-slips-bite drill rod product are mainly solved. When the efficient zero-slips-bite drill rod is used, upward lifting force and additional slurry stirring force can be generated when a drilling fluid passes through the spiral grooves in the drilling process, so that the sand carrying capacity of the slurry is improved. Meanwhile, the well structure and the drilling parameters such as the number of revolutions and the pressure of a vertical pipe cannot be influenced, the drilling efficiency is certainly improved, and the drilling cost is reduced.
Description
Technical field
The utility model relates to drilling rod, well logging, especially a kind of zero slips of efficient raising hydraulic efficiency drilling rod that bites, and it is that a kind of zero slips of the raising hydraulic efficiency for deep-well squeezes and ruins the drilling rod that bites.
Background technology
Most of drilling company is especially bored in deep-well process in order to solve the problem that drilling fluid desilting and mobility are low in drilling well, conventionally can adopt and improve standpipe pressure, changes mud density or improve discharge capacity by changing the method for borehole size.By improving discharge capacity, make mud there is the stronger husky ability of taking, though by such method can significantly improve the husky ability of taking of mud because of for a change drilling parameter the safety of drilling well has been caused to certain threat, if improve bit speed by change borehole size, not only to again to casing programme, design, even can cause very large impact to drilling cost.
In order to improve the husky ability of taking of drilling fluid under the prerequisite not changing drilling parameter and casing programme, by increasing helicla flute mechanism on biting drilling tool at zero slips, be good solution.Rely on the structure of drilling tool itself to make drilling tool for mud provides certain stirring power and promote power, just become the very economic and safe method that mud is taken husky ability that solves in drilling process.Helicla flute not only can play the effect of stirring mud, can provide certain power making progress for returning out of mud simultaneously, although be not fairly obvious in the crowded section of ruining of anti-slips and male joint waterpower cleaning end increase spiral fluted scheme to the effect of mud, but the accumulative effect at whole drill string is exactly apparent, by squeeze the section of ruining and male joint waterpower at anti-slips, to clean end increase spiral fluted scheme be the problem that this patent mainly solves.
Summary of the invention
The purpose of this utility model is to provide a kind of zero slips of efficient raising hydraulic efficiency drilling rod that bites, mainly solve that existing zero slips bites drilling rod product for drilling process to be caused changing drilling fluid density, change the technical problem that drilling parameter even changes casing programme because mud is taken husky scarce capacity, during use, in drilling process, drilling fluid, by producing the power of lift upwards and additional stirring mud in spiral fluted process, is improved the husky ability of taking of mud.And the parameter (such as revolution, standpipe pressure etc.) that can not affect casing programme and drilling well simultaneously has a certain upgrade to the efficiency of drilling well, has saved the cost of drilling well.
For achieving the above object, the technical solution of the utility model is:
The zero slips of the efficient raising hydraulic efficiency drilling rod that bites, it comprises tool joint box and fillet of tool joint pins; It is characterized in that: inner connection of this tool joint box has the crowded section of ruining of the crowded anti-slips of the section of ruining spiral fluted of anti-slips.
The zero slips of the described efficient raising hydraulic efficiency drilling rod that bites, is characterized in that: this fillet of tool joint pins is inner to be connected and have male joint waterpower and clean end spiral fluted male joint waterpower and clean end.
The zero slips of the described efficient raising hydraulic efficiency drilling rod that bites, it is characterized in that: this anti-slips squeeze the section of ruining spiral fluted position be from zero slips bite drilling rod the second elevator 18 degree slope end positions to the second elevator circular bead surface end position only, it is to clean end thick section in male joint waterpower that this male joint waterpower is cleaned end spiral fluted position.
The zero slips of the described efficient raising hydraulic efficiency drilling rod that bites, is characterized in that: this anti-slips squeezes the section of ruining helicla flute and is distributed in whole anti-slips and squeezes the section of ruining; Male joint waterpower is cleaned end helicla flute will be distributed in whole male joint waterpower cleaning end.
The beneficial effect of the technical scheme that the utility model provides is:
1) in bite the second elevator shoulder section of drilling rod and male joint waterpower of zero slips, clean end and increase helicla flute, can under the prerequisite that does not change drilling rod mechanical performance, improve the hydrodynamic performance of drilling rod itself, for drilling fluid provides lift upwards and promotes the husky ability of taking of mud.
2) guaranteed zero slips bite size and the structure of drilling rod, do not affected the versatility of this type of drilling tool, the versatility between drilling tool provided great convenience.
3) do not need to adjust drilling parameter and do not need to adjust the husky ability of taking that casing programme just can promote the lift of mud and mud, having saved in a way cost.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
In figure: 1-tool joint box, the anti-slips of 2-squeezes the section of ruining, and the anti-slips of 3-squeezes the section of ruining helicla flute, 4-fillet of tool joint pins, 5-male joint waterpower is cleaned end, and 6-male joint waterpower is cleaned end helicla flute.
The specific embodiment
As shown in Figure 1, the zero slips that the utility model discloses a kind of efficient raising hydraulic efficiency drilling rod that bites.As shown in the figure: it comprises tool joint box 1 and fillet of tool joint pins 4.Inner connection of this tool joint box 1 has the crowded section of ruining 2 of anti-slips that anti-slips squeezes the section of ruining helicla flute 3.Inner connection of this fillet of tool joint pins 4 has the male joint waterpower cleaning end 5 that male joint waterpower is cleaned end helicla flute 6.
The position that this anti-slips squeezes the section of ruining helicla flute 3 be from zero slips bite drilling rod the second elevator 18 degree slope end positions to the second elevator circular bead surface end position only, the position that this male joint waterpower is cleaned end helicla flute 6 is to clean end 5 thick sections in male joint waterpower.
The utility model squeezes in the section of ruining 2 and male joint waterpower is cleaned end 5 and increased helicla flutes 3,6 at the bite anti-slips of drilling rod of zero slips, and the helicla flute that increases similar grooved drill collar by cleaning end in drilling rod female end the second elevator shoulder and male joint waterpower reaches and promotes that mud stirs, the object of raising mud rising power.
