Description
Technical Field
The application belongs to the technical field of oil and gas drilling, and particularly relates to a pulse composite impact drilling tool.
Background
In the oil and gas drilling process, improving the drilling speed is an important measure for reducing the drilling cost and improving the exploration and development benefits. Currently, to accommodate efficient development of complex reservoirs, wellbore trajectory designs are increasingly complex, drilling becomes less drillable into the formation, and drilling acceleration presents a significant challenge. When the drill bit is in contact with a high-strength stratum, strong rock breaking vibration is generated in the rock breaking process of the drill bit, the rock breaking efficiency of the drill bit is low, early abrasion, breakage, tooth breakage and the like of cutting teeth of the drill bit are easy to cause, and the service life of the drill bit is seriously influenced; meanwhile, the well track of the well with the complex structure is complex, the dogleg is large, the horizontal section is long, the well wall has obvious pressure supporting phenomenon on the drill string, the well head load cannot be transmitted to the bottom of the well in a limited way, and the drilling speed is difficult to lift. Therefore, the method for restraining the vibration of the hard stratum drill bit, improving the rock breaking efficiency of the hard stratum drill bit and reducing the underpressure phenomenon of the well with a complex structure is an effective way for realizing speed and efficiency improvement in the current oil and gas drilling process.
The impact drilling technology utilizes the advantage of impact load rock breaking, and impact force is directly applied to the drill bit, so that the rock breaking efficiency of the drill bit can be obviously improved, and the impact drilling technology is widely applied to drilling. However, the direct axial impact has high requirements on the impact resistance of the drill bit, and the impact damage of the drill bit can be caused when the axial impact load is excessive. Torsional impact is beneficial to reducing vibration in the form of stick-slip of the drill bit, but has less contribution to improving the rock breaking efficiency of the drill bit. In order to integrate the advantages of two impact load drilling, in recent years, a composite impact drilling technology of coupling axial impact and torsional impact is proposed. Meanwhile, based on the vibration friction-reducing resistance theory, the static friction between the drill string and the well wall in the sliding drilling process is converted into dynamic friction by utilizing the composite impact load to act on the drill string, the underpressure effect of the well wall on the drill string is effectively reduced by reducing the friction coefficient, the load transmission is enhanced, and the drilling speed can be obviously improved. Thus, based on the important role of composite impact loads in the acceleration of the well.
In summary, a drilling tool is needed, which not only can adapt to friction resistance reduction of a composite impact drill string of a long horizontal well and a well with a complex structure, but also can be used for composite impact rock breaking and speed increasing of a difficult-to-drill stratum, thereby assisting oil and gas exploration, development, quality improvement and efficiency improvement.

The sleeve 4 is sleeved outside the rotary valve 11, the bearing seat 3 is pressed on the upper part of the sleeve 4 by the upper joint 1, and the lower part of the sleeve 4 is fixedly connected with the shell 2 through threads.
As shown in fig. 1 and 4, for example, the pulse compound impact drilling tool further includes a lock nut 12 and a guide vane 16, wherein the rotary vane 15 is installed at the middle of the rotary valve 11 through a stepped surface of the upper portion of the rotary valve 11 and the lock nut 12, and the guide vane 16 is pressed against the stepped portion of the sleeve 4.

For example, the pulse generating structure (the rotary impeller 15 and the guide impeller 16) is made of metal, has good temperature resistance and oil resistance, and has wide prospect in engineering applications such as deep high-temperature shale gas drilling, geothermal well drilling and the like.
The pulse composite impact drilling tool provided by the embodiment of the application can be connected between a drill string and a drill bit when being used for improving the rock breaking efficiency of the drill bit of the difficult-to-drill stratum and inhibiting the rock breaking stick-slip vibration of the drill bit.
During drilling, the drill bit is connected with the lower joint 8 of the hydraulic pulse type composite impact drilling tool through threads. When drilling fluid enters the hydraulic pulse composite impact tool through the upper drill string, the rotary impeller 15 rotates under the action of the drilling fluid flowing at a high speed and drives the rotary valve 11 to rotate, and the pulse generating mechanism formed by the rotary valve 11 and the fixed disc valve 6 is continuously opened and closed by the aid of the flow channel to form axially downward pulse pressure on the disc valve seat 5, so that an axial impact load is formed. The axial impact load can be decomposed into axial impact and torsion impact under the action of the impact inclined plane and the impact cambered surface of the lower impact seat 7. The disassembled axial impact load and torsional impact load are transmitted to the drill bit through the lower joint 8, so that the composite impact to the drill bit is formed. The ratio of axial impact load to circumferential torsional impact load may be adjusted by selecting different angle impact surfaces 18 prior to drilling.
When the drill bit is severely slimy and vibrated, a hydraulic pulse composite impact drilling tool with a high-angle impact inclined plane can be adopted, and the proportion of torsional impact load is increased, so that the drill bit is mainly inhibited from breaking rock and being slimy, the drill bit is protected, and the service life of the drill bit is prolonged. When the selected drill bit has stronger impact resistance and the rock breaking efficiency of the drill bit when meeting the stratum is lower, the hydraulic pulse composite impact drilling tool with a low impact angle can be selected, and the impact rock breaking capacity of the drill bit is improved by increasing the axial impact load component, so that the rock breaking effect and the mechanical drilling speed of the drill bit are improved.
The pulse compound impact drilling tool of the present embodiment utilizes hydraulic energy to form pressure pulses and converts the pressure pulses into axial and torsional impact loads to the sub 8. Based on the vibration antifriction theory of the drill string, the hydraulic pulse type composite impact drilling tool is connected in the middle of the drill string, the upper connector 1 is connected with the upper drill string, the lower connector 8 is connected with the lower drill string, and when the drilling fluid flows through the hydraulic pulse type composite impact drilling tool, the composite impact vibration friction reduction resistance to the lower drill string is formed.
