Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a mechanical deviation prevention and drilling speed increasing tool while drilling. Background Art

[0002] With the continuous deepening of the oil exploration and development field, a major challenge faced is the large formation dip angle and serious well deviation in inclined formations. These problems not only directly affect the wellbore quality but also reduce the drilling speed. After the well deviation exceeds the standard, deviation correction operations are required, which not only prolong the drilling cycle but also significantly increase the drilling cost, severely restricting the progress of exploration and development. As one of the frontiers of current drilling technologies, vertical drilling technology has the ability to actively prevent and correct well deviation, can effectively release the drilling pressure, greatly improve the drilling efficiency, and ensure downhole safety at the same time. Compared with traditional drilling technologies, this technology is a strategic and revolutionary high-tech, and thus has received great attention and emphasis from various countries.

[0003] After in-depth research and investigation of foreign vertical drilling instruments, vertical drilling systems with various deviation correction methods have been developed, including push-type, pointing-type, etc. These systems all adopt a combination of mechanical, electronic, and hydraulic technical means to achieve a high degree of automation and intelligence. The vertical drilling products of some foreign companies have reached a quite mature commercial level, forming a fully automated rotary steerable vertical drilling system. This system has been widely used in China. However, the existing vertical drilling systems combining machinery, electricity, and hydraulics have certain limitations in the application of deep wells and ultra-deep wells. Since the system contains electronic components inside, the performance of these devices is unstable in high-temperature environments, and the temperature resistance ability is poor, making it difficult to operate in ultra-deep wells.

The lower valve body oil circuit joint 56 is communicated with the lower valve body oil circuit insertion 53 in the lower valve body lower plate 39. The piston 58 is of a cylindrical structure. A piston sleeve 59 is sleeved outside the piston 58. The piston sleeve 59 is fixedly connected to the actuator body 55. The piston 58 can axially move in the piston sleeve 59. The support block 60 is sleeved outside the piston 58. The support block 60 is fixedly connected to the piston 58. A spring limiting plate 57 is provided on the outer wall of the support block 60;

[0106] The spring limiting plate 57 is of a rectangular structure. A hole for the axial movement of the support block 60 is provided at the center of the spring limiting plate 57. A number of centering springs 61 are provided on the inner wall of the spring limiting plate 57. The spring limiting plate 57 is arranged on the outer wall of the actuator body 55. The spring limiting plate 57 is fixedly connected to the actuator body 55. The centering springs 61 limit the support block 60. The connecting body outer sleeve 62 is of an annular structure. The connecting body outer sleeve 62 is arranged on the outer wall of the connecting body 54;

[0107] In the actuator, the piston 58 can push the support block 60 to eject outward under the drive of the hydraulic oil in the hydraulic power measuring mechanism, and can return the support block 60 under the elastic force of the centering springs 61 on the spring limiting plate 57 when the supply of hydraulic oil stops.

[0108] Under the reciprocating motion of the plunger 37 in the first plunger assembly, the first CVR one-way valve and the second CVR one-way valve draw hydraulic oil from the oil return conduction pipe 20 into the high-pressure oil circuit pipe 42. Through the high-pressure oil circuit pipe 42, the hydraulic oil flows through the lower valve body lower plate 39 and enters the annular oil storage space between the middle groove of the lower valve body lower plate 39 and the lower outer sleeve 17 of the plunger. It flows into the corresponding valve core sleeve 50 through the through hole provided on the outer wall of the middle groove of the lower valve body lower plate 39 and into the actuator through the through hole provided on the connecting body 54, so that the support block 60 in the actuator abuts against the well wall outward;

[0109] Under the reciprocating motion of the plunger 37 in the second plunger assembly, the third CVR one-way valve and the fourth CVR one-way valve suck hydraulic oil through several through holes provided on the outer wall of the oil inlet overflow conduction pipe 43, flow through the high-pressure oil conduction pipe 19 and enter the oil storage cylinder connecting body 15, and are discharged to the oil circuit connection groove through the oil port provided on the outer wall of the oil storage cylinder connecting body 15, and are injected into the two high-pressure oil cylinder assemblies and the measuring assembly through the oil circuit connection groove. The hydraulic oil pushes the high-pressure piston 31 in the high-pressure oil cylinder assembly to overcome the high-pressure oil cylinder spring 33, and buffers and decompresses the hydraulic oil through the action of the high-pressure oil cylinder assembly. The decompressed hydraulic oil in the oil circuit connection groove flows into the measuring assembly through the high-pressure piston outer sleeve 21 and pushes the hanging weight 24 downward. The weight head 28 always points to the center of the earth under the action of gravity. When the vertical drilling system tilts more than 1.5°, the weight head 28 on the low side presses down and contacts the corresponding stepped ring 46, so that the valve core rod 51 corresponding to the stepped ring 46 moves downward against the elastic force of the valve core spring 52 to close the through hole of the middle groove of the corresponding lower valve body lower plate 39. At this time, there is no hydraulic oil supply on the low side of the well inclination, and the high side works normally and the lower actuator support block works normally to push against the high side of the well inclination for deviation correction.

[0110] The following details the actual working scenario of a mechanical anti-deviation drilling speed-up tool while drilling.

[0111] During the actual working process, the upper end and the lower end of the central shaft 1 of the mechanical anti-deviation drilling speed-up tool while drilling are respectively connected to the drill pipes, and the connected vertical drilling system is lowered into the well. When the drill string rotates, the eccentric mechanism provided in the central shaft 1 drives the hydraulic power measuring mechanism to generate high-pressure oil and inject it into the actuator. The high-pressure oil passes through the piston 58 in the actuator to make several support blocks 60 in the actuator extend outward. After the support blocks 60 extend, they can further stabilize the measuring assembly in the hydraulic power measuring mechanism to judge the well inclination angle. After the measuring assembly judges the well inclination angle, the weight head 28 moves downward under the action of the hydraulic oil, so that the support blocks 60 on the low side retract, and the support blocks 60 on the high side continue to extend and push against the high side of the well inclination.

[0112] It can be understood that the above-mentioned various embodiments mentioned in the present invention can be combined with each other to form a combined embodiment without violating the principle logic. Due to space limitations, the present invention will not elaborate on them.

[0113] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0114] The utility model provides a mechanical drilling-while-drilling anti-inclination drilling speed-up tool, which connects the mechanical drilling-while-drilling anti-inclination drilling speed-up tool to a drill pipe to form a vertical drilling system, and uses an anti-rotation mechanism to prevent the mechanical drilling-while-drilling anti-inclination drilling speed-up tool from rotating during operation, and transmits the kinetic energy generated by the drilling top drive through an eccentric structure provided in the middle of the mandrel mechanism to a hydraulic power measuring mechanism as a driving power, so that when the vertical drilling system tilts, the hydraulic power measuring mechanism drives the actuator to correct the inclination of the vertical drilling system. The mechanical drilling-while-drilling anti-inclination drilling speed-up tool adopts a fully mechanical structure, avoiding the disadvantage that electronic components cannot be applied to ultra-deep well environments. When the vertical drilling system has inclination during operation, the hydraulic power measuring mechanism links the actuator to perform inclination correction movement, thereby achieving the purpose of judging and controlling the inclination in the vertical drilling system without using electronic components, so that the vertical drilling system can be applied to the high temperature and high pressure environment of ultra-deep wells.
