Description
Technical Field
The invention belongs to the field of petroleum drilling engineering, relates to a drilling tool for drilling, and particularly relates to a drilling tool assembly for inhibiting resonance of a lower drill column and stabilizing drilling pressure.
Background
In modern oil drilling, in order to increase the mechanical drilling speed, a hydraulic impact hammer or an air hammer and the like are used for generating impact force for a drill bit so as to improve the efficiency of breaking rocks. When drilling, weight is applied to the drill bit, causing the teeth on the drill bit to bite into the rock and break up the rock to increase the depth of the well. The weight on bit is formed by the weight of the drill collar in the drill string in the drilling fluid (the actual weight of all drill collars in the drilling fluid is greater than the weight on bit). Since each different drill bit will have the optimum weight on bit, the length of the drill collar required to create the optimum weight on bit can be calculated, which is the neutral section position when the drill string is not vibrating. As the drill string vibrates, the neutral section will move up and down, but normally the amplitude will be small. The drill string is in tension and compression, respectively, above and below the neutral section. One type of approach to increasing the efficiency of breaking rock is to generate impact forces, such as air hammers, hydraulic hammers, and the like. Because these impact forces have a relatively fixed frequency period, when this frequency is integral multiple of the axial natural frequency of the drill collar, the entire drill string will resonate, which is characterized by a large increase in bit pressure over the expected periodicity. This not only greatly shortens the life of the drill bit, but also causes the drill string and other tools to fail.
Because the environment in the well is very complex, the condition of generating resonance is difficult to calculate accurately in theory, so that the working frequency of the tool cannot be determined, and the factor causes the use limitation of the tool capable of greatly improving the mechanical drilling speed.
Through the search of published patent documents, no published patent for solving the resonance problem similar to or similar to the present invention is found.

In order to improve the axial jarring effect and avoid the downward resistance to the central axial column caused by the liquid existing at the bottom in the drill bit, a plurality of drilling fluid diversion channels 16 are arranged at the bottom of the drill bit at the position. A hydraulic turbine is fixedly installed at the upper part in the drill bit above the disc-shaped knocking hammer, the hydraulic turbine is in a hollow shaft shape, a normally open valve 11 is coaxially installed in the hydraulic turbine, and the valve is controlled by a control rod of the telescopic short section; the stator of the hydraulic turbine is fixedly connected with the inside of the drill bit, the lower coaxial shaft of the turbine rotor is connected with a spring, and the spring is connected with the upper plane of the disc-shaped disc body of the disc-shaped knocking hammer. The spring is always in a compressed state, so that the guide plate connected to the disc-shaped knocking hammer body is tightly pressed with the spiral inclined plane of the spiral section inclined plate at the lower part of the guide plate.
The working principle of the invention is as follows:
in the drilling lower drill string assembly there is a section with zero axial force, known in the art as a neutral section. And the damping short section is arranged on the upper part of the neutral section by utilizing the characteristic that the neutral section is a tension-compression dividing point. When the drill string is normally drilled, the drill string section is pulled, the short section is in a stretching state, and the volume of the damping cavity is minimum. When the axial vibration force is increased, the neutral section is driven by the axial pressure wave to move up and down greatly. As the axial pressure peak moves upward, the neutral section also moves upward. When the central section exceeds the position of the damping short section, the short section can be axially pulled and converted into axially compressed state. The short section generates axial deformation (shortening) under the action of axial pressure to compress the spring to increase the volume of the damping cavity, and the drilling fluid is sucked into the negative pressure action cavity, so that the elastic energy generated by axial compression is consumed, and the axial force cannot be directly uploaded. When the vibration wave reaches the peak and enters the wave trough, the axial pressure of the short section is reduced or converted into tension, the elastic force of the spring is released and compresses the damping cavity, and the drilling fluid is discharged from the damping cavity, namely, part of the axial elastic force is supplemented. When the next wave crest arrives, the short section finishes the processes of sucking the drilling fluid and compressing the spring again until the wave troughs discharge the drilling fluid and release part of elastic force. This corresponds to the addition of an amplitude absorber and scrambler to the lower drill string that does not interfere with proper drilling in the middle of the drill string. The characteristics of the damping short joint that the drilling fluid is drawn and pressed to perform the assistant action of the drilling fluid and the spring and the axial deformation energy is consumed can be utilized, so that the development of resonance can be effectively inhibited.
A telescopic short section and a control rod are added above a drill bit, a hydraulic turbine is a hollow shaft, and a normally open valve is arranged in the shaft. The telescopic short section is connected with the drill collar and the drill bit from top to bottom, and the control rod is arranged in the telescopic short section and connected with the telescopic short section outer barrel. Before the bit pressure is applied, a main body of drilling fluid flows through the hollow shaft, and part of the drilling fluid flowing through the hydraulic turbine cannot enable the turbine to work normally. When bit pressure is applied, the telescopic short section is compressed, the control rod moves towards the direction of the bit along with the telescopic short section to push the valve in the hollow shaft of the hydraulic turbine to be closed, and drilling fluid completely passes through the hydraulic turbine to enable the hydraulic turbine to enter a normal working state. At the moment, the rotor of the hydraulic turbine drives the spring and the disc-shaped knocking hammer to rotate, when the disc-shaped knocking hammer rises to the highest point along with the spiral inclined plane of the spiral section inclined plate, a knocking head of the disc-shaped knocking hammer knocks the anvil to complete circumferential impact of the drill bit, and meanwhile, the disc-shaped knocking hammer falls to the lowest point of the spiral inclined plane under the action of elastic force of the spring to realize axial impact on the interior of the drill bit through the central shaft column; at the moment, the disc-shaped knocking hammer and the anvil are not contacted any more due to the height difference, and the anvil cannot prevent the knocking hammer from continuing to rotate along with the turbine rotor. Because the spiral inclined plane of the spiral section inclined plate can enable the disc-shaped knocking hammer body to move up and down, axial downward impact can be formed while circumferential knocking is finished, and the purpose of hydraulic double-acting shock is achieved.
Through engineering tests, the resonance effect of the drill rod is eliminated and inhibited ideally, and conditions are created for improving the production efficiency.
