Description

Technical Field

[0001] The present invention relates to the field of geological exploration technology, and in particular to an automated wellbore inclination measuring device and method. Background Art

[0002] Well inclination refers to the angle between the central axis of a point in an oil or water well and the plumb line of the earth. Its range is 0° to 180°. Well inclination is used to indicate the inclination of the wellbore trajectory. When drilling a vertical well, we should try our best to control the size of the well inclination (the smaller the well inclination, the better), while in directional wells and horizontal wells, the well inclination should be controlled within an appropriate range. During the drilling process, only by accurately measuring the wellbore's well inclination can the direction of the wellbore be controlled.

[0003] Application No. CN94221032.8 discloses a wellbore inclination measuring device, which consists of a frame ruler, a measuring rope, and a reading disk. The frame ruler is made of a ruler with length scales engraved on the center symmetrically, the reading disk has azimuth scales engraved on the circumference, the disk is engraved with depth rays, and the depth rays are engraved with vertex scales. The coordinates of the measuring rope at the wellhead deviating from the center of the wellhead during the process of lowering the measuring rope into the wellbore are measured by the frame ruler, and the corresponding points are found on the reading disk to obtain the deviation (azimuth) and vertex angle (inclination) of the wellbore.

[0004] The above-mentioned inclinometer can only measure the inclinometer for vertical wellbores, and the inclinometer range is small. Moreover, it can only measure the inclination of a fixed point, and cannot measure the inclination change of a section, and the data is relatively small. The present invention is designed to address the above-mentioned defects. The device can measure wellbores with different inclinations, and the inclination can be adjusted arbitrarily, which is more practical. In addition, the device can measure the inclination in different directions in the wellbore, and can also measure the inclination change at one end, and the measurement data is very rich.

[0013] The present invention also provides an automated wellbore inclination measuring device and method, comprising the following steps:

[0014] S1: Fix the equipment. First, place the equipment in the drilled wellbore. The opening circle in the middle of the support frame is concentric with the wellbore. Start the angle adjustment mechanism to make the detection rod parallel to the preset wellbore slope and the detection rod is at the center of the diameter hole.

[0015] S2: perform angle adjustment. If the wellbore is vertical, the stepper motor C is started, and the gear of the stepper motor C is fixedly connected to the arc rack, thereby driving the connecting head to slide in the slide groove of the arc sliding frame until the angle of the detection rod is consistent with the angle of the wellbore, that is, the vertical state. The next step is to start the stepper motor B, thereby driving the detection rod to move downward until the inclinometer mechanism extends into the wellbore; if the wellbore is inclined relative to the ground, then it is necessary to drive the arc sliding frame to descend while adjusting the angle of the detection rod, so that the center of the arc sliding frame descends to a position that coincides with the center of the wellhead, so that the detection rod can be consistent with the preset angle of the wellbore and concentric after adjusting the inclination. Specifically, the stepper motor C is started, and the gear of the stepper motor C is fixedly connected to the arc rack, thereby driving the connecting head to slide in the slide groove of the arc sliding frame until the angle of the detection rod is consistent with the angle of the wellbore. The next step is to start the stepper motor B, thereby driving the detection rod to move until the inclinometer mechanism extends into the well.

[0016] S3: Release the pressure wheel. When the inclinometer mechanism extends into the well, the electric push rod starts, driving the traction rod to slide downward, thereby driving the connecting rod to slide downward, so that the wire rope is relaxed. After the wire rope is relaxed, the telescopic frame extends under the action of the compression spring until the pressure wheel contacts the well wall.

[0017] S4: To measure the inclination, the probe rod continues to move downward under the drive. When the inclination in the well deviates from the preset inclination, the well wall and the probe rod will have an inclination angle, but the balance rod is always close to the well wall, so that the balance rod rotates on the telescopic frame, so the balance rod will have an inclination angle with the probe rod, and the pendulum needle will rotate on the scale plate, so that the sensor senses the change in scale, which is then transmitted to the cloud for observation and recording. Sensors in different directions will have different scale changes, so the recorded data is more accurate.

[0018] The beneficial effects of the present invention compared with the prior art are:

[0019] (1) When the present invention is in use, it can measure the inclination of wellbores with different inclinations. The stepper motor B in the angle adjustment mechanism drives the connector to slide in the slide groove in the arc-shaped sliding frame, so that the angle of the detection rod can be adjusted to be consistent with the angle of the preset wellbore, which is very convenient.

[0020] (2) When the present invention is in use, the physical detection method of the inclinometer can ensure a higher accuracy of inclinometer measurement, and the inclinometer adopts multiple detection points for detection, which can not only detect the slope changes in different directions, but also measure the slope change value of a distance, so that the measurement data is richer.

[0046] The present invention also provides an automated wellbore inclination measuring device and method, comprising the following steps:

[0047] S1: Fix the equipment. First, place the equipment in the drilled wellbore. The opening circle in the middle of the support frame 18 is concentric with the wellbore. Start the angle adjustment mechanism to make the detection rod 13 parallel to the preset wellbore slope and the detection rod 13 is at the center of the diameter hole.

[0048] S2: Angle adjustment. If the wellbore is vertical, the stepper motor C30 is started, and the gear of the stepper motor C30 is fixedly connected to the arc rack 27, thereby driving the connector 28 to slide in the slide groove of the arc sliding frame 22 until the angle of the detection rod 13 is consistent with the angle of the wellbore, that is, the vertical state. The next step is to start the stepper motor B29, thereby driving the detection rod 13 to move downward until the inclinometer extends into the well; if the wellbore is inclined relative to the ground, then the arc sliding frame 22 needs to be driven while adjusting the angle of the detection rod 13. The frame 22 descends, so that the center of the arc-shaped sliding frame 22 descends to a position coincident with the center of the wellhead, so that the detection rod 13 can be consistent with the preset angle of the wellbore and concentric after adjusting the inclination. Specifically, the stepper motor C30 is started, and the gear of the stepper motor C30 is fixedly connected to the arc-shaped rack 27, thereby driving the connecting head 28 to slide in the slide groove of the arc-shaped sliding frame 22 until it slides to the angle of the detection rod 13 consistent with the angle of the wellbore. In the next step, the stepper motor B29 is started, thereby driving the detection rod 13 to move until the inclinometer mechanism extends into the well.

[0049] S3: Release the pressure wheel 12. When the inclinometer mechanism extends into the well, the electric push rod 17 starts, driving the traction rod 14 to slide downward, thereby driving the connecting rod 15 to slide downward, thereby relaxing the wire rope 16. After the wire rope 16 is relaxed, the telescopic frame 4 extends under the action of the compression spring 6 until the pressure wheel 12 contacts the well wall.

[0050] S4: Inclination measurement is performed. The detection rod 13 continues to move downward under the drive. When the slope in the well deviates from the preset slope, the well wall and the detection rod 13 will have an inclination angle, but the balance rod 11 is always close to the well wall, so that the balance rod 11 rotates on the telescopic frame 4, so the balance rod 11 will have an inclination angle with the detection rod 13, and the pendulum needle 8 will rotate on the scale plate 7, so that the sensor 9 senses the change of the scale, which is then transmitted to the cloud for observation and recording. Sensors 9 in different directions will have different scale changes, so that the recorded data is more accurate.

[0051] Working principle: When the present invention is used, the device is first placed at the drilled wellbore, the opening circle in the middle of the support frame 18 is concentric with the wellbore, and the angle adjustment mechanism is activated to make the detection rod 13 parallel to the preset wellbore slope, and the detection rod 13 is at the center of the diameter hole;

[0052] If the wellbore is vertical, the stepper motor C30 is started, and the gear of the stepper motor C30 is fixedly connected to the arc rack 27, thereby driving the connector 28 to slide in the slide groove of the arc slide frame 22 until the angle of the detection rod 13 is consistent with the angle of the wellbore, that is, the vertical state. The next step is to start the stepper motor B29, thereby driving the detection rod 13 to move downward until the inclinometer extends into the well; if the wellbore is inclined relative to the ground, then the arc slide frame 22 needs to be driven downward while adjusting the angle of the detection rod 13. , so that the center of the arc-shaped sliding frame 22 drops to a position that coincides with the center of the wellhead, so that the detection rod 13 can be consistent with the preset angle of the wellbore and concentric after adjusting the inclination. Specifically, the stepper motor C30 is started, and the gear of the stepper motor C30 is fixedly connected to the arc-shaped rack 27, thereby driving the connector 28 to slide in the slide groove of the arc-shaped sliding frame 22 until the angle of the detection rod 13 is consistent with the angle of the wellbore. Next, the stepper motor B29 is started, thereby driving the detection rod 13 to move until the inclinometer mechanism extends into the well;

[0053] When the inclinometer mechanism extends into the well, the electric push rod 17 starts, driving the traction rod 14 to slide downward, thereby driving the connecting rod 15 to slide downward, so that the wire rope 16 is relaxed. After the wire rope 16 is relaxed, the telescopic frame 4 extends under the action of the compression spring 6 until the pressure wheel 12 contacts the well wall. Next, the detection rod 13 continues to move downward under the drive. When the slope in the well deviates from the preset slope, the well wall and the detection rod 13 will have an inclination angle, but the balance rod 11 is always close to the well wall, so that the balance rod 11 rotates on the telescopic frame 4, so the balance rod 11 will have an inclination angle with the detection rod 13, and the pendulum needle 8 will rotate on the scale plate 7, so that the sensor 9 senses the change in scale, which is then transmitted to the cloud for observation and recording. Sensors 9 in different directions will have different scale changes, so that the recorded data is more accurate.

3. The automated wellbore inclination measuring device according to claim 1, characterized in that: The support frame (18) is made of pure steel, and steel barbs are distributed and installed on the bottom of the support frame (18).

4. An automated wellbore inclination measurement method, applicable to the automated wellbore inclination measurement device according to any one of claims 1 to 3, comprising the following steps: S1: Fixing the equipment, firstly placing the equipment at the drilled wellbore, making the opening circle in the middle of the support frame (18) concentric with the wellbore, starting the angle adjustment mechanism, making the detection rod (13) parallel to the preset wellbore inclination, and making the detection rod (13) at the center of the diameter hole; S2: Angle adjustment is performed. If the wellbore is vertical, the stepper motor C (30) is started, and the gear of the stepper motor C (30) is fixedly connected to the arc-shaped rack (27), thereby driving the connector (28) to slide in the slide groove of the arc-shaped sliding frame (22) until the angle of the detection rod (13) is consistent with the angle of the wellbore, that is, the vertical state. Next, the stepper motor B (29) is started, thereby driving the detection rod (13) to move downward until the inclinometer extends into the well. If the wellbore is inclined relative to the ground, then the arc-shaped sliding frame (22) needs to be driven while adjusting the angle of the detection rod (13). The movable frame (22) descends, so that the center of the arc-shaped sliding frame (22) descends to a position that coincides with the center of the wellhead, so that the detection rod (13) is adjusted to be consistent with the preset angle of the wellbore and concentric, and the stepper motor C (30) is started, and the gear of the stepper motor C (30) is fixedly connected to the arc-shaped rack (27), thereby driving the connector (28) to slide in the slide groove of the arc-shaped sliding frame (22) until the angle of the detection rod (13) is consistent with the angle of the wellbore, and the next step is to start the stepper motor B (29), thereby driving the detection rod (13) to move until the inclinometer mechanism extends into the well; S3: the pressure wheel (12) is released. When the inclinometer mechanism is extended into the well, the electric push rod (17) is started, driving the traction rod (14) to slide downward, thereby driving the connecting rod (15) to slide downward, thereby relaxing the wire rope (16). After the wire rope (16) is relaxed, the telescopic frame (4) is extended under the action of the compression spring (6) until the pressure wheel (12) contacts the well wall; S4: Inclination measurement is performed, and the detection rod (13) continues to move downward under the drive. When the inclination in the well deviates from the preset inclination, an inclination angle is generated between the well wall and the detection rod (13). However, the balance rod (11) is always in close contact with the well wall, so that the balance rod (11) rotates on the telescopic frame (4), and thus the balance rod (11) and the detection rod (13) generate an inclination angle, and the pendulum needle (8) rotates on the scale plate (7), so that the sensor (9) senses the change of the scale, which is then transmitted to the cloud for observation and recording. Sensors (9) in different directions will have different scale changes, so that the recorded data is more accurate.
