Description

Technical Field

[0001] This invention belongs to the field of oil and gas drilling and production technology, and relates to an electric suspension device and its usage method. Background Technology

[0002] The casing-and-wellbore suspension testing technology, with its high efficiency and low cost, has been widely used in production logging testing operations. These operations include, but are not limited to, pressure recovery testing, water well pressure drop monitoring, downhole temperature measurement, and corrosion monitoring, which are of invaluable significance for determining the production capacity of oil and gas wells and for in-depth research on reservoir parameters and their dynamic changes. However, current casing-and-wellbore suspension construction in oil and gas production wells still faces a series of technical challenges. Traditional construction methods mainly rely on steel wires to directly suspend logging instruments inside the wellbore. This method is cumbersome, prone to wire breakage leading to well falls, and wastes production resources. Another method involves sending a suspension device carrying logging instruments into the wellbore via cable or steel wire. At a predetermined location, the suspension device is released using a deployment device to collect logging data, and then retrieved after data collection. However, in this process, the suspension device needs to be disconnected from the transport medium (such as steel wire or cable) after entering the well and automatically anchored at the predetermined position. Most existing release devices use a rigid support as the main body, equipped with toothed anchoring springs or support arms, and are fixed with fixing pins. After fixing, the anchoring springs or support arms still need to be tied and secured with easily breakable rope knots such as cotton thread. These devices either use the impact force during the lowering process to cut the fixing pins to release the device, or break the binding knots through friction during the lifting process, causing the anchoring springs or support arms to open, and then use the friction and jamming between the anchoring springs and the wellbore to break the fixing pins. However, the structural design of these tools has inherent defects, leading to many difficulties in actual operation. Specifically, existing release devices are not convenient to operate and are easily restricted by wellbore conditions. Due to the inability to accurately position, sometimes the device is randomly released or cannot be released at all, or even damaged. More seriously, accidents such as the instrument getting stuck or falling into the well occur frequently, which not only seriously affects the normal production and maintenance of oil and gas wells, but also greatly reduces the productivity of oil and gas wells. Therefore, there is an urgent need for a more efficient and safer suspension device to solve these problems.

[0003] Although some related patents have proposed solutions, such as the downhole instrument re-deployment device disclosed in Chinese invention patent application number CN202111190471.X and the drop-off tool proposed in Chinese invention patent application number CN202210238086.6, these technologies still have certain limitations. For example, they are mostly applicable to open-hole well operations, but cannot effectively implement suspension operations within the casing of production wells. In addition, these technologies are accompanied by certain construction risks, low construction efficiency, and high production costs. At the same time, their complex structure, cumbersome operation, and insufficient reliability introduce certain uncertainties in actual operation, making it impossible to accurately, quickly, and safely complete the deployment of suspension devices within the casing of oil and gas production wells. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem that the existing drop device has a complex structure, is cumbersome to operate, and lacks reliability, which leads to certain uncertainties in actual operation and makes it impossible to accurately, quickly and safely complete the drop operation of the suspension device in the well pipe of oil and gas production. The invention provides an electric drop device for the suspension device and its usage method.

[0005] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides an electric suspension device, characterized in that it includes a motor device connected via a quick-connect mechanism and a release short-circuit; the motor device includes a motor connected to the quick-connect mechanism, the motor being connected to a bridle connector, and a cable passing through the bridle connector and connected to the motor; the release short-circuit includes a lead screw mechanism connected to the quick-connect mechanism, the lead screw mechanism being connected to a pawl, the pawl being connected to a lower suspension device connector for connecting the suspension device; the drive shaft of the motor passes through the quick-connect mechanism and is connected to a rotating shaft in the lead screw mechanism, providing power for the opening and closing of the pawl.

[0006] Further improvements are made in the following aspects: The quick-connect mechanism includes quick-connect slips, and a reset pin is provided on the quick-connect slips; when the quick-connect slips are open, the reset pin is in the open state, and the motor device is connected to the release section; when the quick-connect slips are compressed to the horizontal state, the reset pin is in the retracted state, and the motor device is separated from the release section.

[0007] The lead screw mechanism includes a rotating shaft disposed in the outer tube of the lead screw, a fixed sleeve and a slip ring being engaged on the rotating shaft; a spring is sleeved on the rotating shaft at a position between the fixed sleeve and the slip ring; one end of the slip ring is engaged in the spring and the other end is engaged in a pawl.

[0008] The pawl includes a pawl outer tube, on which a pawl is movably connected via a pin. When the spring at the slip ring is relaxed, the pawl is in the retracted position, and the pawl locks the lower suspension device connector. When the spring at the slip ring is compressed, the pawl opens, and the lower suspension device connector of the suspension device disengages from the pawl, thus achieving disengagement.

[0009] The pin is made of wear-resistant material; one end of the pin is fixed to the outer tube, and the other end passes through the rotation center of the chuck.

[0010] The spring is made of wear-resistant material.

[0011] The quick-connect slip is made of alloy material.

[0012] The motor is an explosion-proof DC motor; the motor is connected to the power supply via a cable, which passes through the waterproof sealing structure inside the bridle connector to ensure that the motor can still work normally in harsh environments.

[0013] The motor is connected to a control system for controlling the motor's start, stop, and rotation direction, as well as monitoring the device's operating status and fault conditions. The control system is connected to a remote control console via wired or wireless means to achieve remote control and monitoring.

[0014] Secondly, the present invention provides a method of using the above-mentioned electric suspension device, comprising: Step 1: Before the electric release device of the suspension device is put into operation, place the lower suspension device into the lower end of the release short circuit and lock it in place; connect the motor device and the release short circuit through the quick-connect mechanism. Step 2: Connect the cable head to the upper part of the horse head connector, lower the electric suspension device into the well, and when it is lowered to the designated position, supply negative power to the motor. The motor drives the rotating shaft to rotate, and the pawl opens. When the pawl is opened to the maximum state, the lower suspension device connector is disengaged and short-circuited. Step 3: The motor current decreases and changes, the motor idles, turn off the power, and the work is complete.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an electric deployment device for a suspension device. Through a cleverly designed quick-connect mechanism, the motor and the release arm are efficiently and securely connected, greatly simplifying the structural complexity of traditional release devices and significantly improving operational convenience and reliability. This invention eliminates cumbersome mechanical connections and complex power transmission mechanisms, employing a quick-connect mechanism to achieve a rapid and reliable connection between the motor and the release arm, significantly reducing assembly and disassembly difficulties and improving operational efficiency. The motor is directly connected to the rotating shaft in the lead screw mechanism via a drive shaft, reducing intermediate transmission links and making power transmission more direct and efficient. This also reduces potential failure points and improves the overall reliability of the system. Precise control of the motor allows for precise adjustment of the lead screw mechanism and the opening and closing action of the chuck, ensuring the stability and accuracy of the suspension device during deployment or retrieval. The quick-connect mechanism enables faster connection and separation between the motor and the release arm, allowing for quick deployment or retrieval of the suspension device and improving operational efficiency. The electric deployment device of this invention uses a high-pressure resistant, explosion-proof motor and a bridle connector, ensuring the stability and safety of the device in harsh environments. The design of the lead screw mechanism and chuck fully considers the stress conditions and reliability requirements in actual operations, employing high-strength materials and optimized structural design to improve the system's load-bearing capacity and service life. Intelligent motor control allows for real-time monitoring and adjustment of the system's operating status, timely detection and handling of potential faults, and reduced uncertainty and risk during operation. This invention features a simple structure, convenient operation, and high safety. The suspension device can be precisely deployed to a predetermined position according to construction needs. Powered by the logging vehicle's onboard power supply, after the downhole instrument string is lowered to the predetermined position, the deployment device rotates the lever according to a preset time, releasing the locking gripper for automatic deployment. It can be used with different steel wires and cables for oil, water, and gas well logging, offering excellent sealing and pressure resistance. The deployment time difference is less than or equal to 1 minute, and the deployment error is ≤1 meter. Successful deployment allows for timely verification of the suspension effect, providing greater accuracy and intuitiveness. It avoids the problems of mechanical release, difficult release, low efficiency, and insufficient safety associated with traditional release devices, ensuring the timeliness, safety, and accuracy of the suspension position, thus improving operational efficiency and construction safety.

[0016] This invention discloses a method for using an electrically operated suspension device. This method, with its clear step-by-step instructions, simplifies the use of the device, reduces operational difficulty, and improves work efficiency. The quick-connect mechanism between the motor and the release switch allows for faster assembly and disassembly, further shortening operation time. Precise motor control enables precise adjustment of the rotating shaft and the opening and closing of the chucks, ensuring the stability and accuracy of the suspension during deployment. When the chucks are fully open, the lower suspension device connector smoothly disengages from the release switch, achieving precise deployment. The high-voltage resistance and explosion-proof characteristics of the motor, along with the waterproof design of the head connector, ensure safe and stable operation of the device in harsh downhole environments. Current change monitoring and motor idling design allow for timely power cut-off after the chucks open, preventing motor overload or damage and improving the overall reliability of the system. This method avoids the safety hazards that may arise from traditional manual operation, reducing operator risk. The electrically operated method reduces labor costs while improving operational efficiency and lowering overall costs. This method is applicable to oil well operations of different depths and specifications, exhibiting strong versatility and adaptability. By adjusting motor parameters and control system settings, different operating environments and needs can be easily met. Attached Figure Description

When the spring 3013 at the slip ring 3014 is relaxed, the chuck 302 is in the retracted position, locking the lower suspension device connector 303. When the slip ring 3014 is in the compressed state of the spring 3013, the chuck 302 opens, and the lower suspension device connector 303 disengages from the chuck 302, achieving disengagement. The pin 3021 is made of high-strength wear-resistant materials, including stainless steel, alloy steel, cast iron, high manganese steel series, wear-resistant chromium cast iron series, and wear-resistant alloy steel series, ensuring that the chuck 302 maintains stable rotation and durability during frequent clamping and loosening.

[0030] This invention discloses an electric deployment device for a suspension device. A carefully designed quick-connect mechanism 3 efficiently and reliably connects the motor unit 1 and the release short-circuit 3, greatly simplifying the structural complexity of traditional release devices and significantly improving operational convenience and reliability.

It avoids the problems of mechanical release, difficulty in release, low efficiency and insufficient safety of the original release device, and ensures the timeliness, safety and accuracy of the suspension position of the construction, thus improving the work efficiency and construction safety.

[0031] This invention also discloses a method of using a suspended electric delivery device, comprising: Step 1: Before the electric release device of the suspension device is put into operation, the lower suspension device 303 is placed into the lower end of the release short-circuit 3 and locked in place; the motor device 1 and the release short-circuit 3 are connected through the quick-connect mechanism 2. Step 2: Connect the cable head to the upper part of the head connector 101. Lower the electric release device of the suspension device into the well. When it is lowered to the designated position, supply negative power to the motor 102. The motor 102 drives the rotating shaft 3011 to rotate. The pawl 302 opens. When the pawl 302 is opened to the maximum state, the lower suspension device connector 303 disengages from the release short circuit 3. Step 3: The current of motor 102 decreases and changes, motor 102 runs idle, the power is turned off, and the work is completed.

[0032] When connecting the motor device 1 and the release short-circuit 3, open the quick-connect slip 201 to open the reset pin 202, then quickly align and connect the lower end of the motor device 1 to the corresponding part of the release short-circuit 3 to achieve a secure connection and prevent relative rotation between the two. When separating the motor device 1 and the release short-circuit 3, compress the quick-connect slip 201 to a horizontal position to retract the reset pin 202, thereby achieving rapid separation. Operate the lead screw structure 301 of the release short-circuit 3 to control the movement of the slip ring 3014 by rotating the rotating shaft 3011, which in turn controls the retraction and opening of the pawl 302 to lock or release the lower suspension device connector 303. When the slip ring 3014 moves to the spring relaxed state, the pawl 302 retracts and locks the lower suspension device connector 303. When the slip ring 3014 moves to the spring compressed state, the pawl 302 opens and releases the lower suspension device connector 303, realizing the deployment or retrieval of the suspension device. The operation of the lead screw structure 301 is achieved by the power provided by the motor device 1. The motor device 1 is connected to the rotating part of the lead screw structure 301 through the rotating shaft 3011, thereby controlling the rotation direction and speed of the rotating shaft.

[0033] This invention discloses an electric deployment device for a suspension device. A carefully designed quick-connect mechanism 3 efficiently and reliably connects the motor unit 1 and the release short-circuit 3, greatly simplifying the structural complexity of traditional release devices and significantly improving operational convenience and reliability.

Through intelligent control of the motor 102, the system's operating status can be monitored and adjusted in real time, allowing for timely detection and handling of potential faults, reducing uncertainty and risk during operation.

[0034] The working process of this invention is as follows: This invention addresses well logging operations in oil and gas production wells, particularly in long-term dynamic monitoring and wellbore corrosion detection, by providing an electrically operated suspension device. The solution includes a motor and a release / short-circuit mechanism. With this device, during wellbore suspension operations, when the suspension reaches the required position inside the wellbore, the surface winch stops lowering. The operator receives power from the surface housing, and the suspension device quickly and accurately deploys the suspension by rotating. The operator can visually determine whether the suspension has been successfully deployed by observing the same current reading on the surface.

[0035] The bridle connector 101 is used to connect the upper conveyor of the logging instrument string. It has an internal connecting wire to provide a stable power supply to the electric delivery device. The motor 102, after supplying power to the release device via the ground instrument, rotates to power the release device. The quick-connect mechanism 2, located at the lower end of the motor unit, is used for quick connection and fixation between the motor unit and the release short-circuit. The lead screw structure 301, located at the upper end of the release short-circuit, mainly controls the rotation shaft, thereby controlling the closing of the chuck 302. The chuck 302, located at the lower middle end of the release short-circuit, mainly locks the suspension device. The lower suspension device connector 303, located at the lowest end of the delivery device, is used for connecting the matching suspension device. The overall design features a small outer diameter, short length, and integrated functions. During the casing and tubing suspension inspection process, before the instrument operates, place the suspension device connector into the lower end of the release section, and rotate the screw mechanism 301 counterclockwise until it stops rotating. At this point, the suspension device is already locked inside the release section. Then, connect the motor part to the release short circuit 3 through the quick-connect mechanism 2, and connect the upper connector to the cable head. Lower the instrument into the well. When the instrument is lowered to the designated position, supply negative power to the instrument. The motor will rotate, driving the screw mechanism to rotate. The pawl will slowly open. When the pawl is opened to the maximum state, the suspension device will disengage from the release section, the motor current will decrease, the motor will idle, and the power will be turned off. The release operation is complete.

[0036] This invention features a simple structure, convenient operation, and high safety. The suspension device can be precisely deployed to a predetermined position according to construction needs. Powered by the logging vehicle's onboard power supply, after the downhole instrument string is lowered to the designated position, the deployment device automatically deploys the device by rotating the lever and releasing the locking grip according to a preset time. It can be used with different steel wires and cables for oil, water, and gas well logging, offering excellent sealing and pressure resistance. The deployment time difference is less than or equal to 1 minute, and the deployment error is ≤1 meter. Successful deployment allows for timely verification of the suspension effect, providing greater accuracy and intuitiveness. It avoids the problems of mechanical release, difficult release, low efficiency, and insufficient safety associated with traditional release devices, ensuring timely construction, safety, and accurate suspension positioning, thus improving operational efficiency and construction safety.
