Description

Technical Field

[0001] The invention belongs to the technical field of drilling, in particular to a petroleum drilling speed-up device. Background Art

[0002] In recent years, discovering oil and gas in deep hard strata and complex geological conditions has become an important task in current exploration and development.

[0003] During the drilling process, the hardness of the formation and the difficulty of drilling continue to increase with the increase of well depth. Improving the drilling speed in hard formations is one of the world's recognized problems.

[0004] At present, the drilling of oil fields has developed from vertical wells to directional wells and horizontal wells. The drill tools are usually close to the lower well wall. The friction between the drill tools and the well wall is too great, making it difficult to transmit the drilling pressure to the drill bit. As a result, domestic and foreign oil fields generally have problems such as slow drilling speed, short drill tool life, long drilling cycle and high drilling cost in the drilling of deep wells and hard rock formations, which restricts the overall benefits of exploration and development.

[0005] In the existing scheme, hydraulic oscillators are often used to generate vibrations to increase the drilling speed. However, the oscillators used in this scheme have a relatively complex structure, too many rotating parts, high cost, high loss, and a short service life. In addition, as the length of the well increases, other existing tools are difficult to fully meet the construction requirements. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art, simplify the internal structure, cooperate with the rotating disk to change the flow direction and position of the drilling fluid, make multiple groups of swing rods swing in turn and hit the vibration column, generate axial vibrations with varying sizes and frequencies, and increase the drilling speed, the present invention proposes an oil drilling speed-up device.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the oil drilling speed-up equipment described in the present invention comprises an outer cylinder, an upper joint and a lower joint are installed at both ends of the outer cylinder, and the part of the lower joint located in the outer cylinder is a contact end;

[0010] A guide block is installed at the lower end of the upper joint, and an annular flow channel is formed between the guide block and the channel on the upper joint.

[0011] Preferably, the swing rods are evenly arranged in multiple groups around the center line of the outer cylinder, and the ends of the swing rods are equipped with knocking balls, and the ends of the swing rods and the knocking balls are located below the flow channel;

[0012] A knocking block is installed on the surface of the vibration column, and the heights of the knocking blocks are inconsistent.

[0013] Preferably, the lower end of the elastic rod is mounted on a mounting block, and the other end of the elastic rod is in contact with the swing rod.

[0014] Preferably, a support plate is installed on the elastic rod, the surface of the support plate is in contact with the surface of the swing rod, and an elastic layer is installed on the surface of the support plate.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 7 As shown, the oil drilling speed-up equipment of the present invention comprises an outer cylinder 1, an upper joint 11 and a lower joint 12 are installed at both ends of the outer cylinder 1, and the part of the lower joint 12 located in the outer cylinder 1 is a contact end 121;

[0033] A vibration column 2 is installed in the outer cylinder 1, a flow slot 21 is provided on the vibration column 2, a fixing block 22 is provided at the lower end of the vibration column 2, a fixing slot 122 is provided on the contact end 121, and the fixing block 22 is installed in the fixing slot 122;

[0034] A mounting block 3 is mounted on the inner wall of the outer tube 1, a connecting ring 31 is mounted on the mounting block 3, a swing rod 32 is mounted on the connecting ring 31, the other end of the swing rod 32 is in contact with the upper surface of the vibration column 2, an elastic rod 34 is mounted between the mounting block 3 and the swing rod 32, and the elastic rod 34 is located below the swing rod 32;

[0035] A guide block 41 is installed at the lower end of the upper joint 11, and an annular flow channel is formed between the guide block 41 and the channel on the upper joint 11;

[0036] When working, the speed-up device is connected between the drill pipe and the drill bit, so that the upper joint 11 is connected to the drill pipe and the lower joint 12 is connected to the drill bit. Driven by the drilling rig installed on the surface platform, the drill bit pressed against the formation below the water surface starts to drill downward. At the same time, during the drilling process, the mud pump installed on the surface platform will also synchronously send the drilling fluid into the drilled wellbore to ensure smooth drilling.

[0037] At the same time, the pumped drilling fluid enters the outer tube 1 from the upper joint 11, then enters the drill bit from the lower joint 12, and then is ejected from the drill bit into the well. Under the action of pressure, the drilling fluid entering the outer tube 1 will impact the swing rod 32 in the outer tube 1, causing the swing rod 32 to swing downward at an accelerated speed, so that the end of the swing rod 32 hits the vibration column 2. Since the vibration column 2 is installed on the lower joint 12, the vibration effect generated by the swing rod 32 is transmitted to the drill bit, generating a vibration effect on the drill bit, thereby increasing the drilling speed.

[0038] At the same time, after the swing rod 32 is impacted by the drilling fluid and swings downward and hits the vibration column 2, the end of the swing rod 32 will be affected by the reaction force generated by the impact, so that the swing rod 32 has a tendency to swing upward. At the same time, after the swing rod 32 swings downward, it will compress the elastic rod 34, which will also cause the swing rod 32 to have a tendency to swing upward. At this time, due to the movement of the swing rod 32 in the outer tube 1 and the influence of the suddenly expanded space from the upper joint 11 to the outer tube 1, the flow of drilling fluid in the outer tube 1 is relatively turbulent, so that the swing rod 32 can swing upward under the action of the elastic force and the reaction force, so that the swing rod 32 can hit the vibration column 2 after being impacted by the drilling fluid again, thereby generating axial vibration and improving the drilling speed.

[0039] At the same time, due to the effect of the guide block 41 on the flow channel formed by the channel separation in the upper joint 11, when the swing rod 32 is located at the initial position at the top, the end of the swing rod 32 is just located directly below the flow channel, and the impact force of the drilling fluid on the swing rod 32 is the largest. As the swing rod 32 swings downward, the drilling fluid gradually diffuses in the outer tube 1, so that the downward impact force on the swing rod 32 is relatively reduced. Therefore, after the swing rod 32 hits the vibration column 2, the swing rod 32 can swing upward under the action of the elastic force and the reaction force, so that the swing rod 32 is subjected to a relatively large impact force again, causing the swing rod 32 to hit the vibration column 2 downward;

[0040] At the same time, the drilling fluid entering the outer tube 1 continues to move downward after driving the swing rod 32 to hit the vibration column 2. After that, the drilling fluid passes through the circulation groove 21 and enters the lower joint 12, and finally sprays out from the drill bit into the well.

[0041] As an embodiment of the present invention, the swing rods 32 are evenly arranged in multiple groups around the center line of the outer tube 1, and the ends of the swing rods 32 are installed with knocking balls 33, and the ends of the swing rods 32 and the knocking balls 33 are located below the flow channel;

[0042] A knocking block 23 is installed on the surface of the vibration column 2, and the height of the knocking block 23 is inconsistent;

[0043] By providing a plurality of sets of swing rods 32, the vibration column 2 can be struck relatively continuously and densely, thereby increasing the size and frequency of the existing axial vibration and improving the drilling speed. At the same time, due to the inconsistent heights of the knocking blocks 23 and the swing rods 32 being installed at different positions in the outer tube 1, after the flow of drilling fluid in the outer tube 1 is disturbed, the swing rods 32 will not swing downward consistently, that is, each swing rod 32 will not strike the vibration column 2 at the same time to generate axial vibration. In this case, the frequency and size of the axial vibration generated on the speed-up equipment will change, thereby utilizing the relatively changing vibration effect to improve the drilling effect of the drill bit and the drilling speed.

[0044] As an embodiment of the present invention, the lower end of the elastic rod 34 is mounted on the mounting block 3, and the other end of the elastic rod 34 is in contact with the swing rod 32;

[0045] At the same time, one end of the elastic rod 34 is fixedly mounted on the mounting block 3, while the other end of the elastic rod 34 is in a free state, so that when the swing rod 32 swings downward, the swing rod 32 will contact and compress the elastic rod 34, causing the elastic rod 34 to deform, and then after the swing rod 32 hits the vibration column 2, the swing rod 32 is driven to swing upward and return to its original position. At the same time, since the elastic rod 34 and the swing rod 32 are in contact with each other and there is no fixed connection, when the swing rod 32 swings upward, the swing angle of the swing rod 32 will not be restricted by the elastic rod 34, thereby increasing the possibility of the swing rod 32 swinging upward and returning to its original position. At this time, in conjunction with the drilling fluid input by the mud pump in a pulsed manner, it can further ensure that the swing rod 32 swings back and forth in a cycle, and the swing rod 32 can continuously hit the vibration column 2, so that the speed-up equipment can increase the drilling speed under the action of axial vibration.

[0046] As an embodiment of the present invention, a support plate 341 is installed on the elastic rod 34, the surface of the support plate 341 is in contact with the surface of the swing rod 32, and an elastic layer is installed on the surface of the support plate 341;

[0047] The contact area between the swing rod 32 and the elastic rod 34 is increased by the support plate 341, ensuring that the swing rod 32 can be stably and fully subjected to the elastic effect of the elastic rod 34, ensuring that the swing rod 32 hits the vibration column 2, and thus improving the drilling speed. At the same time, the swing rod 32 is buffered by the support plate 341 and the elastic layer to reduce the wear on the swing rod 32, thereby avoiding the swing rod 32 from breaking after local wear and tear, which affects the normal use of the speed-up equipment.

[0048] As an embodiment of the present invention, a rotating disk 4 is installed on the guide block 41, a through hole 42 is opened on the rotating disk 4, a guide cylinder 43 is installed at the lower end of the through hole 42, and an angle exists between the center line of the guide cylinder 43 and the vertical direction;

[0049] After the drilling fluid enters the channel in the upper joint 11, the drilling fluid will pass through the through hole 42 on the rotating disk 4, and then the drilling fluid will be affected by the guide cylinder 43, so that the rotating disk 4 is affected by the reaction force and rotates. In this process, the position of the drilling fluid passing through the through hole 42 will also rotate. Therefore, among the multiple groups of swing rods 32, the swing rod 32 impacted by the drilling fluid will also change, that is, the swing rod 32 impacted by the drilling fluid will swing downward and hit the vibration column 2. After the rotating disk 4 rotates and the drilling fluid passing through the through hole 42 leaves the position of the impacted swing rod 32, the downward swing rod 32 will swing upward under the action of elastic force and reaction force and return to the original position, and then wait to swing downward again to hit the vibration column 2, generate axial vibration, and increase the drilling speed;

[0050] At the same time, by rotating the rotating disk 4, the position of the drilling fluid that impacts the swing rod 32 is changed, so that the swing rod 32 in the outer tube 1 can be impacted and swung downward in turn, thereby ensuring the reciprocating up and down swing of the swing rod 32 and the impact of the swing rod 32 on the vibration column 2, thereby utilizing axial vibration to increase the drilling speed.

[0051] As an embodiment of the present invention, a vibration block 5 is installed on the vibration column 2, and a spring is installed between the vibration block 5 and the fixed block 22;

[0052] At the same time, after the drilling fluid impacts the swing rod 32, the drilling fluid will continue to flow downward. During this process, the drilling fluid will contact and impact the vibration block 5, and then the vibration block 5 will vibrate under the action of the spring, so that the speed-up device will produce axial vibration, further increasing the drilling speed.

[0053] As an embodiment of the present invention, the vibration blocks 5 are provided in multiple groups, the vibration blocks 5 are connected to each other through springs, and a protruding rod is provided on the side wall of the flow slot 21, and the protruding rod blocks the movement of the vibration blocks 5;

[0054] At the same time, a plurality of vibration blocks 5 are provided, and the vibration blocks 5 are connected by springs, so that the vibration blocks 5 can continue to move after being impacted by the drilling fluid, thereby continuously generating axial vibrations and improving the drilling speed. At the same time, during the vibration of the vibration block 5, the vibration block 5 will be disturbed by the raised rod, increasing the difficulty of passing through, thereby generating greater vibrations when the vibration block 5 passes over the raised rod, thereby improving the drilling speed.

[0055] As an embodiment of the present invention, the length of the swing rod 32 is less than or equal to half of the inner diameter of the outer tube 1, and the radius of the connecting ring 31 is greater than the radius of the upper joint 11 located inside the outer tube 1;

[0056] Since there are multiple sets of swing rods 32, the swing rods 32 will not contact each other when they swing up and down, thereby avoiding mutual abutment between the swing rods 32, which may cause the swing rods 32 to get stuck. At the same time, since the radius of the connecting ring 31 is larger than the radius of the upper joint 11 located in the outer cylinder 1, the maximum angle of the swing rod 32 when it swings upward is limited, thereby avoiding the swing rod 32 from impacting the rotating disk 4 when it swings upward or the swing rod 32 from contacting the inner wall of the upper joint 11 upward, which may affect the normal use of the speed-up equipment.

[0057] The specific workflow is as follows:

[0058] When working, the speed-up device is connected between the drill pipe and the drill bit, so that the upper joint 11 is connected to the drill pipe and the lower joint 12 is connected to the drill bit. Driven by the drilling rig installed on the surface platform, the drill bit pressed against the formation below the water surface starts to drill downward. At the same time, during the drilling process, the mud pump installed on the surface platform will also synchronously send the drilling fluid into the drilled wellbore to ensure smooth drilling.

[0059] At the same time, the drilling fluid entering the outer tube 1 will impact the swing rod 32 in the outer tube 1, causing the swing rod 32 to swing downward at an accelerated speed, so that the end of the swing rod 32 hits the vibration column 2, so that the impact force generated by the swing rod 32 is transmitted to the drill bit;

[0060] At the same time, after the swing rod 32 is impacted by the drilling fluid and swings downward and hits the vibration column 2, the end of the swing rod 32 is affected by the reaction force generated by the impact, so that the swing rod 32 has a tendency to swing upward. At the same time, after the swing rod 32 swings downward, it compresses the elastic rod 34, which also makes the swing rod 32 have a tendency to swing upward, so that the swing rod 32 swings upward, so that the swing rod 32 hits the vibration column 2 again.

[0061] At the same time, due to the effect of the guide block 41 on the flow channel formed by the channel separation in the upper joint 11, when the swing rod 32 is at the initial position at the top, the end of the swing rod 32 is just located directly below the flow channel, and the impact force of the drilling fluid on the swing rod 32 is the largest. As the swing rod 32 swings downward, the drilling fluid gradually diffuses in the outer tube 1, so that the downward impact force on the swing rod 32 is relatively reduced. Therefore, after the swing rod 32 hits the vibration column 2, the swing rod 32 can swing upward under the action of the elastic force and the reaction force, so that the swing rod 32 is subjected to a relatively large impact force again, causing the swing rod 32 to hit the vibration column 2 downward.

[0062] At the same time, the drilling fluid entering the outer tube 1 continues to move downward after driving the swing rod 32 to hit the vibration column 2. After that, the drilling fluid passes through the circulation groove 21 and enters the lower joint 12, and finally sprays out from the drill bit into the well.

[0063] At the same time, since the heights of the knocking blocks 23 are inconsistent and the swinging rods 32 are installed at different positions in the outer tube 1, after the flow of drilling fluid in the outer tube 1 is disturbed, the swinging rods 32 will not swing downwards consistently, that is, each swinging rod 32 will not hit the vibration column 2 at the same time to generate axial vibration. In this case, the frequency and magnitude of the axial vibration generated on the speed-up device will vary, thereby utilizing the relatively varying vibration effect to improve the drilling effect of the drill bit and the drilling speed.

[0064] At the same time, when the swing rod 32 swings downward, the swing rod 32 will contact and compress the elastic rod 34, causing the elastic rod 34 to deform, and then after the swing rod 32 hits the vibration column 2, it drives the swing rod 32 to swing upward and return to the original position. At the same time, because the elastic rod 34 and the swing rod 32 are in contact with each other and there is no fixed connection, when the swing rod 32 swings upward, the swing angle of the swing rod 32 will not be restricted by the elastic rod 34, so that the possibility of the swing rod 32 swinging upward and returning to the original position is increased. At this time, the drilling fluid input by the mud pump in a pulsed manner can further ensure that the swing rod 32 swings back and forth in a cycle, and the swing rod 32 can continuously hit the vibration column 2, so that the speed-up equipment can increase the drilling speed under the action of axial vibration;

[0065] The support plate 341 increases the contact area between the swing rod 32 and the elastic rod 34, ensuring that the swing rod 32 can be stably and fully subjected to the elastic effect of the elastic rod 34. At the same time, the support plate 341 and the elastic layer buffer the swing rod 32, reducing the wear on the swing rod 32.

[0066] Among the multiple groups of swing rods 32, the swing rods 32 impacted by the drilling fluid will also change, that is, the swing rods 32 impacted by the drilling fluid will swing downward to impact the vibration column 2, and after the rotating disk 4 rotates and the drilling fluid passing through the through hole 42 leaves the position of the impacted swing rod 32, the downward swing rod 32 will swing upward under the action of elastic force and reaction force and return to the original position, and then wait to swing downward again to impact the vibration column 2, generate axial vibration, and increase the drilling speed;

[0067] At the same time, by rotating the rotating disk 4, the position of the drilling fluid that impacts the swing rod 32 is changed, so that the swing rod 32 in the outer tube 1 can be impacted and swung downward in turn, thereby ensuring the reciprocating up and down swing of the swing rod 32 and the impact of the swing rod 32 on the vibration column 2, thereby utilizing axial vibration to increase the drilling speed;

[0068] At the same time, after the drilling fluid impacts the swing rod 32, the drilling fluid will continue to flow downward. During this process, the drilling fluid will contact and impact the vibration block 5, and then the vibration block 5 will vibrate under the action of the spring, so that the speed-increasing device will generate axial vibration, further increasing the drilling speed;

[0069] At the same time, a plurality of vibration blocks 5 are provided, and the vibration blocks 5 are connected by springs, so that the vibration blocks 5 can continuously move after being impacted by the drilling fluid, thereby continuously generating axial vibrations, thereby increasing the drilling speed. At the same time, during the vibration of the vibration blocks 5, the vibration blocks 5 will be disturbed by the protruding rods, thereby generating greater vibrations when the vibration blocks 5 pass over the protruding rods, thereby increasing the drilling speed.

[0070] Since there are multiple sets of swing rods 32, the swing rods 32 will not contact each other when they swing up and down, thereby avoiding mutual abutment between the swing rods 32, which may cause the swing rods 32 to get stuck. At the same time, since the radius of the connecting ring 31 is larger than the radius of the upper joint 11 located in the outer cylinder 1, the maximum angle of the swing rod 32 when it swings upward is limited, thereby avoiding the swing rod 32 from impacting the rotating disk 4 when it swings upward or the swing rod 32 from contacting the inner wall of the upper joint 11 upward, which may affect the normal use of the speed-up equipment.
