Description

A torque value detection device on the shackle equipment of drilling tools

Technical field

The invention belongs to the technical field of petroleum machinery and equipment, and relates to a torque value detection device on a shackle equipment on a drilling tool.

Background technique

In drilling operations, each specification of drilling tool has a specified make-up torque value. Improper tightening torque may cause threaded joints to fail. Over-torque will cause excessive plastic deformation of the joint shoulder or sealing surface, leading to seal failure. Under-torque will cause insufficient contact stress on the sealing surface, causing mud leakage or tripping. Therefore, during operation, the operator must strictly implement the standard requirements and use equipment such as drill pipe power tongs or iron drill tools to tighten the drilling tool to the specified torque value.

Currently, there are many types of drilling tools and shackle equipment in use in oil fields, such as DB lifting tongs, drill pipe power tongs, iron drillers, etc. These devices are also different in appearance and principle, so each manufacturer also has different testing methods for the accuracy of the buckling torque value of the device itself. Generally, sensors are used to detect the tension value when the clamp body is buckled, and then the product of the effective force arm is used to calculate the torque value. These methods are all indirect measurement methods. Due to changes in the torque arm, different friction moments, and poor pressure repeatability, the measurement accuracy is not high, the detection efficiency is low, and the interchangeability is not good. And after the equipment leaves the factory, it cannot be calibrated. Therefore, there is a need for a portable device that can directly measure the drill pipe torque to more accurately detect the actual output working torque of the top shackle equipment.

Detailed ways

The present invention will be described in detail below with reference to the drawings and specific embodiments.

Referring to Figure 1, a torque value detection device on a shackle equipment for a drilling tool according to the present invention includes a hollow base 4. A torque sensor 3 is fixed at the bottom end of the hollow base 4. The top opening of the hollow base 4 is fixed to the joint sleeve 2. There is a connector 1 sleeved in the connector sleeve 2. One end of the connector 1 protrudes from the top of the connector sleeve 2. The other end of the connector 1 extends into the hollow base 4 and is fixed with the torque sensor 3. The signal line of the torque sensor 3 is connected to the display. 5 connections.

The joint sleeve 2, joint 1 and torque sensor 3 keep the center lines coincident; the joint 1 passes through the joint sleeve 2 and is connected to the torque sensor 3, moving the torque generation position downward to the outside of the body of the shackle device. The joint and the torque sensor are connected using the standard button type of the drilling tool. They can also be connected using key connections or other methods, including threaded connections, key connections, flange connections, or square hole connections.

A flange head is fixed at one end of the joint sleeve 2, and the joint sleeve 2 is fixed on the hollow base 4 through the flange head and connecting bolts 6.

The torque sensor 3 is a flange-type torque sensor. The other end of the joint 1 is fixed with a fixed base plate. The fixed base plate and the flange of the torque sensor 3 are fixed with bolts.

The top of the hollow base 4 is also fixed with eye bolts.

As shown in Figure 2, the monitoring method using the torque value detection device on the above-mentioned drilling tool shackle equipment is:

In the initial state, insert the joint 1 into the upper flange hole of the torque sensor 3 through the inner hole of the joint sleeve 2, and keep the centers of the upper and lower joints coincident. The upper shackle equipment 8 sets the target torque value A for buckling, then the upper clamp clamps the joint 1, and the lower clamp clamps the lower joint sleeve 2; the upper and lower joints are buckled.

The torque generated by the upper and lower clamps of the upper shackle equipment 8 is transmitted to the upper and lower flanges of the torque sensor 3 respectively. At this time, the actual torque exerted by the shackle equipment on the drilling tool is the torque value detected by the torque sensor 3, and the read value is B.

Do this several times, record the target values as: A1, A2, A3..., and the actual reading detection values are B1, B2, B3..., compare the target value A and the actual value B, and perform statistical calculations. If the deviation is within the allowable error range, the torque value of the equipment under inspection is accurate and credible. Otherwise, the cause of the false value of the equipment under inspection needs to be identified and torque calibration performed.

The torque detection device of the drilling tool tightening equipment of the present invention transmits the torque exerted by the upper and lower clamps of the detected equipment to the torque sensor and displays it in real time. The equipment under inspection and the detection device become a system, and there is no need to apply external counter-torque fixation to the detection device during operation. The equipment is simple and convenient to install and use, small in size and easy to transport. It can realize the inspection of the entire life cycle of the inspected shackle equipment without being restricted by the site.

In addition, this invention basically meets the requirements for accurate detection of make-up and break-out torques of all types of existing make-up equipment, and has strong adaptability.
