Description

Technical Field

[0001] This invention relates to the field of oilfield drilling equipment technology, and in particular to a drilling propulsion device. Background Technology

[0002] In the process of oil and gas exploration and development, the final step is to connect the oil reservoir and the wellbore, thereby enabling the extraction of oil and gas resources within the reservoir.

[0003] Currently, deep penetration drilling mainly includes the following two steps: first, the casing is drilled through, and then the formation drilling tool is re-entered. The drilling tool passes through the casing hole to drill the oil layer, thereby forming a crude oil drainage channel.

[0004] However, in formation drilling, gravity propulsion is often used, where the drill bit is pressurized for propulsion. Adjusting the drilling pressure is difficult, and weight rods need to be lowered, further increasing the labor intensity. Furthermore, current drilling technologies generally require the drilling tools to be pulled out of the ground to determine the drilling length, making real-time monitoring of the drilling footage impossible. Short drilling times and low footage result in more drilling trips, extending the construction period; conversely, excessively long drilling times can easily damage the drilling tools, requiring tripping for repairs, which also prolongs the construction period, severely impacting efficiency and operating costs. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling propulsion device that can adjust drilling pressure and monitor drilling progress in real time, effectively shortening the construction cycle, reducing labor intensity and construction costs.

[0016] The upper sleeve has a first inlet hole on its side wall, and the first sliding member has a second inlet hole on its side wall. High-pressure drilling fluid can flow into the upper sleeve from the first inlet hole and into the first sliding member from the second inlet hole.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] This embodiment provides a drilling propulsion device for propulsion operations in deep-penetrating downhole boreholes. For example... Figure 1 As shown, the drilling propulsion device includes a logging cable 4, a housing 1, a pressurization module 2, and a drilling footage monitoring module 3.

[0046] The housing 1 is hollow, forming an installation cavity to provide installation space for the pressurization module 2 and the drilling footage monitoring module 3. The housing 1 is configured to be lowered into the tubing and sealed to a sealing seat within the tubing. The housing 1, in conjunction with the sealing seat, enables the installation and positioning of the drilling propulsion device. The top of the housing 1 is connected to surface equipment via a logging cable 4, which is used for lifting the housing 1 and for signal transmission. The pressurization module 2 includes a first sliding member 21, which is slidably installed within the installation cavity and extends from the bottom of the housing 1. The first sliding member 21 is connected to the drill bit and configured to push the drill bit forward. The drilling footage monitoring module 3 is located within the installation cavity and electrically connected to the logging cable 4. The drilling footage monitoring module 3 is connected to the first sliding member 21 and is used to monitor the drilling footage of the drill bit. In other words, the displacement of the first sliding member 21 represents the drilling footage of the drill bit. The sliding speed of the first sliding member 21 reflects changes in drilling pressure. This drilling propulsion device can adjust the drilling pressure and monitor the drilling progress in real time, effectively shortening the construction cycle, reducing labor intensity and construction costs.

[0047] Specifically, such as Figures 1-4 As shown, the footage monitoring module 3 includes an electronic chamber 31, a waveguide wire measuring rod 32, a magnetic ring 33, and a signal line 34. The electronic chamber 31 is installed inside the mounting cavity and is electrically connected to the logging cable 4 via the signal line 34. The logging cable 4 provides power to the electronic chamber 31 and transmits signals within it. The waveguide wire measuring rod 32 is connected to the bottom of the electronic chamber 31, and the magnetic ring 33 is fitted over the waveguide wire measuring rod 32 and can slide along the axial direction of the waveguide wire measuring rod 32. The first sliding member 21 is fixedly connected to the magnetic ring 33. The electronic chamber 31 can send excitation pulses to the waveguide wire measuring rod 32 and receive strain pulses transmitted back from the waveguide wire measuring rod 32.

[0048] In other words, the current signal transmitted from the ground is transmitted to the electronic chamber 31 via the logging cable 4. Electronic components within the electronic chamber 31 generate an excitation pulse. The magnetic field generated by this excitation pulse travels at the speed of light from one end of the electronic chamber to the other along the waveguide wire within the waveguide wire measuring rod 32, which is made of a high magnetostrictive material. When this magnetic field intersects with the permanent magnetic field generated by the magnetic ring 33, due to magnetostriction, a mechanical strain pulse is generated at the intersection point on the waveguide wire. This pulse then propagates back from this point to the electronic chamber end at the speed of sound, until it is detected by the detection circuit in the electronic chamber 31. The time between transmitting the excitation pulse and receiving the strain pulse is the time it takes for sound to travel through the waveguide wire. Knowing the speed of sound and the propagation time, the distance between the magnetic ring 33 and the electronic chamber 31 can be determined, and thus the sliding distance of the first sliding member 21 can be determined.

[0049] Optionally, see [link to relevant documentation] Figure 1 and Figure 2 The housing 1 includes a logging bridle 11, a first variable-strut connector 12, and a first limiting connector 13. The logging bridle 11 is a tool used to connect the logging cable 4 and the logging instrument. Various data measured by the downhole instrument are transmitted through the logging bridle 11 to the logging cable 4, and then from the logging cable 4 to the wellhead instrument and the surface panel to complete the logging. This logging bridle 11 is existing technology and will not be described in detail here. The first variable-strut connector 12 is connected to the logging bridle 11, and the first limiting connector 13 is coaxially connected to the first variable-strut connector 12. A first annular platform 121 is provided inside the first variable-strut connector 12, and a second annular platform 131 is provided inside the first limiting connector 13. The electronic housing 31 is sandwiched between the first annular platform 121 and the second annular platform 131. The first annular platform 121 and the second annular platform 131 can position the electronic housing 31, preventing the electronic housing 31 from moving and causing deviations in the displacement test of the first sliding member 21.

[0050] Specifically, the housing 1 also includes a connecting threaded ring 18, which is composed of two half-rings. An installation groove is formed on the outer wall of the first variable-thread connector 12, and the two half-rings are placed in the installation groove with their ends abutting each other. The two ends of the two half-rings are respectively joined by a locating pin 181 and a combination screw 182 to form the connecting threaded ring 18, which can rotate within the installation groove. The outer wall of the connecting threaded ring 18 is threadedly connected to the logging bridle 11, meaning that the first variable-thread connector 12 and the logging bridle 11 can rotate relative to each other, but cannot move axially.

[0051] More specifically, the drilling propulsion device also includes a signal plug 5. The signal plug 5 includes a male plug and a female plug that connect to each other. One of the male and female plugs is fixed to the logging bridle 11 and communicates with the logging cable 4. The other of the male and female plugs is fixed to the first variable-thread connector 12 and communicates with the electronic compartment 31 via a signal line 34. When the male and female plugs are plugged in, signal transmission between the electronic compartment 31 and the logging cable 4 can be achieved.

[0052] Optionally, such as Figure 1 and Figure 3 As shown, the housing 1 also includes an upper sleeve 14 and a sleeve connector 15. The upper sleeve 14 is coaxially arranged with the first limiting connector 13. The sleeve connector 15 is connected to the lower end of the upper sleeve 14. The waveguide wire measuring rod 32 is located inside the upper sleeve 14. The first sliding member 21 is sleeved on the outside of the waveguide wire measuring rod 32 and fixedly connected to the magnetic ring 33. The first sliding member 21 passes through the sleeve connector 15. In this embodiment, a fixed plate 25 is connected to the top of the first sliding member 21, and the magnetic ring 33 is fixed to the fixed plate 25 by a fixing screw 26. A first fluid inlet hole 141 is opened on the side wall of the upper sleeve 14, and a second fluid inlet hole 211 is opened on the side wall of the first sliding member 21. High-pressure drilling fluid can flow into the upper sleeve 14 from the first fluid inlet hole 141 and into the first sliding member 21 from the second fluid inlet hole 211. The flow of high-pressure drilling fluid generates a pressure drop and creates a downward thrust, which in turn drives the first sliding member 21 to slide relative to the sleeve connector 15 along the axial direction of the upper sleeve 14. Furthermore, the magnitude of the thrust can be controlled by controlling the flow rate and volume of the high-pressure drilling fluid; this thrust is the drilling pressure applied to the drill bit by the first sliding member 21.

[0053] Specifically, the housing 1 also includes a lower sleeve 16, which is coaxially arranged with the upper sleeve 14. A sleeve connector 15 connects the upper sleeve 14 and the lower sleeve 16. The pressurization module 2 also includes a second sliding member 22 and a lower connector 23. The second sliding member 22 is connected to one end of the first sliding member 21 that extends out of the sleeve connector 15, and the lower connector 23 is connected to one end of the second sliding member 22 that is away from the first sliding member 21. The lower connector 23 is configured to be connected to the drill bit, and the first sliding member 21 can drive the second sliding member 22 and the lower connector 23 to slide along the axial direction of the lower sleeve 16. In this embodiment, the high-pressure drilling fluid can flow sequentially through the upper sleeve 14, the first sliding member 21, the second sliding member 22, the lower connector 23, the downhole motor, the flexible drill pipe, and the drill bit, and is finally pumped by the mud pump to realize the recycling of the drilling fluid.

[0054] More specifically, the housing 1 further includes a second limiting connector 17, which is connected to the bottom end of the lower sleeve 16 and sleeved over the second sliding member 22. A limiting ring 171 is provided inside the second limiting connector 17. The pressurizing module 2 also includes a connecting sleeve 24, which connects the first sliding member 21 and the second sliding member 22. The bottom end of the connecting sleeve 24 can abut against the limiting ring 171. During the process of the first sliding member 21 driving the second sliding member 22 to slide downwards along the axial direction of the lower sleeve 16, when the bottom end of the connecting sleeve 24 abuts against the stepped surface of the limiting ring 171, the second sliding member 22 fully extends out of the lower sleeve 16. The limiting ring 171 can restrict the connecting sleeve 24 from continuing to move downwards, preventing the connecting sleeve 24 and the second sliding member 22 from dislodging from the lower sleeve 16.

[0055] More specifically, in this embodiment, a first sealing ring 61 is provided between the first sliding member 21 and the sleeve connector 15 to prevent high-pressure drilling fluid from flowing out of the upper sleeve 14 through the gap between the first sliding member 21 and the sleeve connector 15.

[0056] Optionally, see [link to relevant documentation] Figure 1 The outer wall of the sleeve connector 15 is provided with a suspension step, which can abut against the sealing seat connected to the tubing. A main sealing groove is formed on the side wall of the suspension step, and a second sealing ring is sandwiched between the main sealing groove and the sealing seat. In this embodiment, the drilling propulsion device needs to be lowered into the tubing tool during use. The suspension step abuts against the sealing seat connected to the tubing, so that the drilling propulsion device is suspended in the tubing. The second sealing ring seals the gap between the sleeve connector 15 and the sealing seat, thereby allowing all the high-pressure drilling fluid to flow into the upper sleeve 14, and then into the first sliding member 21, thereby driving the first sliding member 21 to slide.

[0057] Optionally, in this embodiment, a third sealing ring 62 is provided between the first variable-stretch connector 12 and the logging bridle 11, and a fourth sealing ring 63 is provided between the electronic compartment 31 and the first variable-stretch connector 12. These seals are used to seal the connection between the signal plug 5, the signal line 34, and the electronic compartment 31 to prevent leakage. Specifically, the first sealing ring 61, the second sealing ring, the third sealing ring 62, and the fourth sealing ring 63 can be selected as rubber sealing rings or felt sealing rings from the prior art.

[0058] Optionally, such as Figure 1 As shown, the drilling propulsion device also includes a display module 7, which is communicatively connected to the drilling footage monitoring module 3 via a logging cable 4. In this embodiment, the magnetic ring 33 moves synchronously with the first sliding member 21. The displacement of the magnetic ring 33 is monitored by the drilling footage monitoring module 3 and transmitted to the display module 7, which displays specific values, thereby facilitating real-time monitoring of the drill bit's drilling footage by construction personnel.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
