Abstract
The utility model discloses a petroleum screw drilling tool. The drilling tool comprises a weighted lever body and a protection pipe disposed outside the weighted lever body. One end of the weighted lever body is provided with a drilling head. The weighted lever body is provided with outer threads comprising a first thread and a second thread. The first thread is intersected with the second thread. The joint part of a connection rod and the weighted lever body is provided with an antiskid ring. A wearproof layer is disposed outside the drilling head. The drilling tool is advantaged by being small in needed external pressure and small in drilling pressure.
Description
Technical field
The utility model relates to a kind of oil and drills through instrument, more particularly, relates to a kind of oil helicoid hydraulic motor.
Background technology
when carrying out oil exploitation and drill through, need to utilize drilling rod, it comprises drilling rod main body or/and connector existing drilling rod.When oil is exploited, complex structure due to stratum, deeply reaching hundreds of rice even in the stratum of thousands of meters, it has a lot of lithospheres or harder stratum, drilling rod is when creeping into, and because lithosphere is harder, drilling rod main body is arranged in stratum and drilling rod main body is cylindrical, the landwaste being drilled through is extremely difficult for being discharged, and landwaste brings pressure to creeping into of drilling rod.And drilling rod main body and drill bit are integrated mechanism, drilling rod, when creeping into, needs top to give very large the pressure of the drill and just can creep into.
Utility model content
Technical problem to be solved in the utility model is to provide the oil helicoid hydraulic motor that a kind of required outside the pressure of the drill is little and drilling pressure is little.
The technical scheme in the invention for solving the above technical problem is:
A kind of oil helicoid hydraulic motor; comprise weighted lever main body and be positioned at the protection tube outside weighted lever main body; one end of described weighted lever main body is provided with in drill bit and weighted lever main body and is provided with external screw thread; described external screw thread comprises the first screw thread and the second screw thread; described the first screw thread and the second screw thread intersect; the junction of described connecting rod and weighted lever main body is provided with a circle antislip ring, and described drill bit is outside equipped with one deck wearing layer.
As preferably, the angle that the first described screw thread and the second screw thread intersect to form is 5 degree-20 degree.
Further, the angle that the first described screw thread and the second screw thread intersect to form is 10 degree.
As preferably, described weighted lever main body and drill bit are heavy metal.
As preferably, the diameter of described antislip ring is less than externally threaded diameter.
To sum up, the beneficial effects of the utility model are:
1, drilling rod main body of the present utility model adopts weighted lever main body, its quality is larger, in drilling process, because himself gravity can make very greatly drill bit creep into downwards, the pressure of the drill that outside gives is reduced, the utility model required outside the pressure of the drill in drilling process is reduced.
2, in weighted lever main body of the present utility model, be provided with external screw thread, and the first screw thread and the second screw thread intersect, make drill bit when creeping into, screw thread both can continue lithosphere to creep into, also make two gaps between screw thread can pile up landwaste, avoid landwaste to bring resistance to creeping into of drill bit, accelerate the speed of creeping into.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in accompanying drawing: 1, connecting rod; 2, antislip ring; 3, weighted lever main body; 4, external screw thread; 5, the first screw thread; 6, the second screw thread; 7, protection tube.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
A kind of oil helicoid hydraulic motor as shown in Figure 1; comprise weighted lever main body 3 and be positioned at the protection tube 7 outside weighted lever main body 3; one end of described weighted lever main body 3 is provided with in drill bit and weighted lever main body 3 and is provided with external screw thread 4; described external screw thread 4 comprises the first screw thread 5 and the second screw thread 6; described the first screw thread 5 and the second screw thread 6 intersect; described connecting rod 1 is provided with a circle antislip ring 2 with the junction of weighted lever main body 3, and described drill bit is outside equipped with one deck wearing layer.In the present embodiment, acting as of protection tube 7 protected weighted lever main body and drill bit, avoids when using, the external screw thread in drill bit and weighted lever main body not being damaged.During use, take off protection tube.When creeping into, because the quality of weighted lever main body is heavier, drill bit is had to downforce, make drill bit obtain the pressure of the drill power, the pressure of the drill power that the required outside of drill bit is provided reduces.Drill bit, in drilling process, can produce landwaste, and talus deposit brings resistance to creeping into of drill bit.The external screw thread arranging in weighted lever main body, and externally threaded the first screw thread and the second screw thread intersect, external screw thread not only can continue rock stratum to creep into, and landwaste can be piled up in the gap between the first screw thread and the second screw thread, reduce the accumulation of landwaste, avoid the impact of landwaste on drill bit, accelerate rate of penetration.Wearing layer has strengthened the abrasion resistance of drill bit.
Embodiment 2:
A kind of oil helicoid hydraulic motor as shown in Figure 1, the present embodiment is substantially the same manner as Example 1, and difference is: the angle that the first described screw thread 5 and the second screw thread 6 intersect to form is 5 degree-20 degree.Utilize the gap that the intersection of the first screw thread and the second screw thread produces to pile up landwaste, the experiment proved that, between the first screw thread and the second screw thread, too hour, gap is too little, does not have the object of piling up landwaste for angle; When angle between the first screw thread and the second screw thread is too large, screw thread is poorly arranged.Consider, the angle that the first screw thread 5 and the second screw thread 6 intersect to form is 5 degree-20 degree.
Embodiment 3:
A kind of oil helicoid hydraulic motor as shown in Figure 1, the present embodiment is optimized embodiment 2, and preferred one group of data in the disclosed number range of embodiment 2 are about to the angle that the first screw thread 5 and the second screw thread 6 intersect to form and are set to 10 degree.
Embodiment 4:
A kind of oil helicoid hydraulic motor as shown in Figure 1, the present embodiment and above-described embodiment are basic identical, and difference is: described weighted lever main body 3 and drill bit are heavy metal.Its relative mass of heavy metal is large, and during given volume, its quality weight, can play the object that the pressure of the drill is provided.Drill bit is also set to heavy metal material, and it can further strengthen the pressure of the drill.
Embodiment 5:
A kind of oil helicoid hydraulic motor as shown in Figure 1, the present embodiment and above-described embodiment are basic identical, and difference is: the diameter of described antislip ring 2 is less than the diameter of external screw thread 4.Antislip ring is mainly to contact with weighted lever main body 3 when connecting for fear of the connecting rod of oil screw rod drilling rod, and when the diameter of antislip ring 2 is excessive, oil screw rod drilling rod is when creeping into, and antislip ring 2 easily causes obstruction to creeping into.
As mentioned above, can realize preferably the utility model.
