Description
Technical Field
The invention belongs to auxiliary equipment for petroleum drilling, and relates to a drilling speed-increasing dynamic compactor.
Background
During the drilling process of the oil field, pressure needs to be applied to the drill bit to force the drill bit to break and cut rock. A common method of applying pressure to a drill bit is to attach a weighted drill pipe (commonly known as a drill collar) above the drill bit. When the drill bit is subjected to super-hard rock stratum, the pressure applied to the drill bit by the gravity of the drill collar is insufficient due to the fact that the super-high pressure is required to be applied to the drill bit. In order to solve the problem, a method of lowering a drill rod to increase the weight of the drill is adopted. However, the weight of the drill rod can not be controlled, the drill rod with a few kilometers is pressurized on the drill bit, after the condition occurs, the drill rod with a few kilometers can bend, and huge friction force is generated between the drill rod and the well wall, so that the power loss can be greatly increased, the abrasion of the drill rod can be increased, the weight of the drill rod with a few kilometers is mostly born by the well wall, the pressure obtained on the drill bit is not large, the increase of the drilling pressure is not obvious, the drilling footage is still slow, and the cutting edge of the drill bit is worn in a wasteful manner. The above problems are more pronounced when drilling inclined wells; when the horizontal well section is drilled, the drill collar is in a horizontal state, and the weight of the drill collar does not increase the weight of the drill bit. Therefore, the method can not effectively increase the weight on bit, and the problems of slow drilling footage and drill bit abrasion still exist.
Disclosure of Invention
The invention aims to design a drilling speed-increasing dynamic compactor, which overcomes the problems, and uses drilling fluid to generate a tamping force to increase the drilling pressure of a drill bit, improve the drilling speed and reduce the abrasion of the drill bit.
The purpose of the invention is realized in the following way: the guide vane is arranged in the upper portion of the hydrodynamic rotary wheel, an outer communicating groove is formed in the side wall of the lower portion of the hydrodynamic rotary wheel, the inner portion of the hydrodynamic rotary wheel is a cavity, an inner communicating groove is formed in the side wall of the upper portion of the hydrodynamic rotary wheel, the upper portion of the cavity of the hydrodynamic rotary wheel is communicated with the outside, the lower portion of the hydrodynamic rotary wheel is sleeved outside the upper portion of the hydrodynamic rotary wheel, the hanging connector is sleeved outside the upper portion of the lower connector, the lower end of the hanging connector is limited by the outer shoulder of the lower connector, the upper portion of the lower connector is connected with the lower portion of the hydrodynamic rotary wheel, the guide vane, the hydrodynamic rotary wheel and the hydrodynamic rotary wheel are placed in an inner cavity of the upper connector, the upper portion of the hanging connector is connected with the lower portion of the upper connector, the outer diameter of the hydrodynamic rotary wheel is larger than the inner diameter of the hanging connector, the hydrodynamic rotary wheel cannot be separated from the hanging connector, the outer communicating groove enables the lower portion of the hydrodynamic rotary wheel to be communicated with the inner cavity, and the outer communicating groove can be communicated with the inner communicating groove when the hydrodynamic rotary wheel rotates, and the lower connector is connected with the lower connector.
The inner wall of the suspension joint is provided with a vertical key slot, the outer wall of the upper part of the lower joint is provided with a vertical bar key, and the vertical bar key is inserted into the vertical key slot, so that the suspension joint and the lower joint cannot rotate relatively.
The beneficial effects of the invention are as follows: the drilling fluid used in drilling is used as a power source, the impulse hydrodynamic rotating wheel accelerates and rotates, so that the outer communicating groove and the inner communicating groove are communicated or closed, and the pressure of the upper end face of the fluid guide body generates high-frequency change due to the high frequency of communication or closing, so that ramming force is generated to tamp the drill bit to crush rock. Therefore, the invention overcomes the problems in the prior art, the drilling fluid is used for generating the ramming force to increase the drilling pressure of the drill bit, the drilling speed can be greatly increased, the abrasion of the drill bit is reduced, the drilling period is greatly shortened, the drilling cost is reduced, and the invention has obvious economic benefit.
