Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and in particular to an online detection image recognition and analysis device for drilling fluid. Background Art

[0002] Drilling fluid is called the "blood" of oil drilling. It plays a very important role in oil and gas drilling projects. It has the functions of cleaning bottom cuttings, cooling and lubricating drill bits and drill strings, balancing formation pressure, and maintaining wellbore stability. It is an indispensable working fluid in drilling projects. The drilling fluid circulating out of the wellbore also carries important formation and engineering information, which is of great significance to the safety control of drilling projects. Specifically, if the drilling fluid at the annulus outlet contains bubbles, it means that a gas-bearing formation has been drilled. The main sources of bubbles include: gas in the pores enters the drilling fluid during the crushing of gas-bearing rocks; gas in the pores of porous reservoirs under underpressure enters the wellbore and invades the drilling fluid under the action of the bottom hole pressure difference; gas in the fracture-cavity system enters the wellbore and invades the drilling fluid during gravity displacement in fractured or fracture-cavity gas reservoirs. Timely identification of bubbles and bubble content in the drilling fluid at the annulus outlet helps to achieve early identification and early warning of gas invasion. In addition, information such as oil droplets in the drilling fluid at the annulus outlet is an important representation of the oil-bearing formations encountered. Whether the drilling fluid contains oil droplets and the size and distribution density of the oil droplets can help to identify the oil layer encountered in real time and evaluate the permeability and oil output of the oil layer. In addition, the information such as the shape and distribution density of the cuttings / solid particles in the drilling fluid at the annulus outlet is also the most intuitive reflection of the lithology of the drilled formation and the stability of the wellbore downhole. Real-time systematic and in-depth scientific analysis of the annular drilling fluid can help to achieve early identification and warning of gas invasion and overflow, real-time judgment of complex working conditions such as wellbore instability, and real-time evaluation of the drilled formation, which has positive scientific significance and engineering application value for the safety control of oil and gas drilling.

[0003] At present, the monitoring and evaluation of the performance of drilling fluid at the annular outlet in the field of oil and gas drilling is often carried out by manually sampling at regular intervals near the position of the vibrating screen in the mud pool for simple and rough evaluation. It is impossible to achieve real-time evaluation, and the evaluation parameters are limited. The main evaluation parameters are limited to the density of the drilling fluid, rheological parameters, whether it contains bubbles, etc. More importantly, the drilling fluid is screened out by the vibrating screen to remove the solid phase. The tiny bubbles in the drilling fluid have been broken and dissipated into the air after being processed by the vibrating screen. Unless the gas invasion is obvious, there are still visible bubbles after the vibrating screen. That is, in the case of micro-gas invasion, conventional logging cannot effectively identify it in time, let alone accurately evaluate the amount of gas invasion. There are similar problems in the identification of oil invasion. In addition, conventional logging is to sample and analyze the cuttings screened out by the vibrating screen at regular intervals. It does not achieve real-time evaluation, and the cuttings are often observed by the naked eye after being clear. The accuracy of its evaluation depends on the experience and knowledge reserve of the on-site technicians, which is subjective and may miss key information. In recent years, some technologies for real-time evaluation of the performance of outlet drilling fluids have emerged in the industry, but most of them are real-time measurements of rheology and density, and do not pay attention to its gas and oil content and cuttings morphology, etc. In addition, the drilling fluids measured are mostly after the solid phase is removed by a vibrating screen, and are not direct measurements of the annulus outlet drilling fluid, which will lose key information.

[0004] At present, there is an urgent need for an online drilling fluid detection image recognition and analysis device, and the use of modern intelligent technology to achieve in-depth mining and comprehensive application of its key information. Summary of the invention

[0016] Based on the above technical solution, compared with the prior art, the present invention can produce the following beneficial effects:

[0017] (1) The drilling fluid online detection image recognition and analysis device is different from the conventional logging method of manually measuring the density and viscosity of the returned drilling fluid. Instead, it obtains real-time photos of drilling fluid samples and uses computer intelligent algorithms to perform real-time analysis on the drilling fluid photos, including information such as bubbles, oil droplets, and rock cuttings. It can then determine in real time whether complex situations such as gas invasion, overflow, and wellbore instability have occurred in the well, and provide early warnings. Compared with conventional logging methods, it is more intelligent and eliminates the problem of conventional logging being highly dependent on the experience and technical level of on-site technicians. The results are more scientific and reliable, and real-time monitoring is truly achieved.

[0018] (2) The drilling fluid online detection image recognition and analysis device directly samples and analyzes from the mud tank. Compared with the conventional logging method, the drilling fluid sample is taken after being processed by the vibrating screen (in the case of trace gas invasion, the gas phase escapes into the air after the vibrating screen treatment, and there will be no bubbles in the drilling fluid). It can detect minor gas invasion and oil invasion more timely.

[0019] (3) The drilling fluid online detection image recognition and analysis device can also extract the specific morphology of rock cuttings by analyzing the drilling fluid rock sample images, and establish real-time lithology, rock mechanics profile, and drillability profile of the drilled formation in conjunction with the database, and evaluate the drilling fluid performance in a more comprehensive manner.

[0020] (4) The sampling, image acquisition, cleaning and drying of the drilling fluid online monitoring image recognition and analysis device are all fully automatic and intelligently controlled, which greatly saves labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the dryer 29 is fixedly installed with a dryer return air duct 32, and the left and right sides of the dryer 29 are connected to the dryer air inlet duct 30. The dryer upper cover 35 at the left and right ends of the dryer 29 is a door-type structure. A working circular hole is opened on the dryer upper cover 35, and the diameter of the circular hole is consistent with the diameter of the sampler metal handle 45. A horizontal sliding guide rail 41 is installed at each end of the dryer 29, and a sliding guide rail controller is installed on the horizontal sliding guide rail 41. The dryer upper cover 35 is opened and closed by slidingly connecting on the horizontal sliding guide rail 41. The ultrasonic cleaner 27 has no top plate, and the dryer 29 has no bottom plate.

[0037] The robotic arm module is a movable structure with four-axis four-degree-of-freedom rotation. The robotic arm module consists of a robotic arm base 22, a robotic arm component, a rotating shaft 23, a rotating shaft 4 and a telescopic shaft 9. The robotic arm component consists of a robotic arm component 1 21, a robotic arm component 20 and a robotic arm component 3 8. The robotic arm components are movably connected through the rotating shaft 23. The rotating shafts 23 between the robotic arm components are equipped with reduction motors to control the rotational movement; the end of the robotic arm component 3 8 is equipped with a rotating shaft 4, and the output end of the rotating shaft 4 is equipped with a telescopic shaft 9. The rotating shaft 4 controls the rotation of the rotating shaft 4 and the telescopic movement of the telescopic shaft 9 by controlling the motor, and the telescopic shaft 9 is connected to the sampler module.

[0038] The sampler module is composed of a sampler glass plate 7, a sampler metal handle 45, and a metal bracket 46. The sampler glass plate 7 is a transparent sampling structure with a slight protrusion in the center. One end of the sampler metal handle 45 is embedded in the telescopic shaft 9, and the other end is inlaid with a metal bracket 46. The sampler glass plate 7 and the metal bracket 46 are placed concentrically with the annular groove in the middle. The sampler glass plate 7 is movably connected to the telescopic shaft 9 of the mechanical arm module through the sampler metal handle to achieve position movement. The presence of the annular groove on the metal bracket 46 prevents the drilling fluid sample from being scattered out of the device after being naturally flattened by gravity; at the same time, the natural flattening method relying on gravity avoids the situation where the bubbles and oil droplets in the sample are destroyed due to mechanical flattening and other flattening methods, and maintains the original shape of the sample as much as possible.

[0039] Furthermore, the drilling fluid drainage module is composed of a drilling fluid drainage pipe 2, a sampling branch pipe 53, a sampling port 54, and a solenoid valve 6.

As long as there is drilling fluid returning from the mud tank, there is always drilling fluid flowing in the drilling fluid drainage pipe 2 to ensure that the drilling fluid inside is the drilling fluid returned from the mud tank in real time. The upstream of the drilling fluid drainage pipe 2 is installed in the middle and lower trough of the mud tank to avoid interference caused by the natural mixing of air into the mud sampling caused by the non-full pipe flow of the mud tank. The sampling branch pipe 53 is arranged and installed in the middle of the drilling fluid drainage pipe 2, and its outlet is the sampling port 54. The solenoid valve 6 is installed on the sampling branch pipe 53. The solenoid valve 6 is connected to the intelligent control unit 19 and the computer 34 through the control harness 5. The intelligent control unit 19 can send instructions to control the opening and closing of the solenoid valve 6 through the control harness 5 to complete the sampling. The solenoid valve 6 is opened, and the drilling fluid flows out through the sampling branch pipe 54. The solenoid valve 6 is closed, and the sampling is completed. The upstream of the drilling fluid drainage pipe 2 can also be installed on the throttling manifold, which mainly depends on whether the drilling fluid returned from the annulus is discharged through the mud tank or through the throttling manifold.

A circular groove is hollowed out in the middle of the limit lower baffle 26 to facilitate cooperation with the sampler and facilitate the transmission of the lower light source. An annular boss is provided in the middle of the lower side of the liftable limit upper baffle 14 to facilitate contact with the outer groove of the sample glass plate 7 during image acquisition, thereby forming a closed space to avoid interference from external light sources. The limit lower baffle 26 is fixedly installed in the middle of the test frame, and the lift limit upper baffle 14 is connected to the retractable light shielding tube 13, and can move up and down along the lift sliding guide rail 36 under the control of the lift sliding slider 50. The lift sliding slider 50 is connected to the intelligent control unit 19 and the computer 34 through the control harness 5 to receive control instructions. The camera module of the test frame includes a camera support plate 51, a high-definition camera 12, and a camera top cover 52, which are installed on the upper part of the test frame 11 from bottom to top.

[0044] When the present invention is working, it can be divided into the device sampling state, the device image acquisition operation state, and the cleaning and drying operation state. Each group of tests needs to go through these three operation states in sequence. After completing one group of tests, it automatically enters the next group of tests. Specifically, the specific implementation of each operation state is as follows:

[0045] The status of the drilling fluid sample received by the device is as follows Figure 1 and Figure 5As shown. The computer 34 controls the reduction motor 1 23 through the intelligent control unit 19 to drive the mechanical arm component 2 20 to rotate, so that the mechanical arm component 2 20 and the drilling fluid sampling port 54 are in a vertical plane, and then the reduction motor 2 24 and the reduction motor 3 4 drive the mechanical arm component 2 20 and the mechanical arm component 3 8 to rotate, so that the telescopic shaft 9 and the sample glass plate 7 are in a horizontal state, and the reduction motor 3 4 controls the telescopic shaft 9 to extend and retract, so that the center point of the sample glass plate 7 is located directly below the sampling port 54. The intelligent control unit 19 controls the electromagnetic valve 6 to open and close by controlling the transmission instruction of the control harness 5 to ensure that an appropriate amount of drilling fluid sample drips to the center position of the micro-convex structure on the surface of the sample glass plate 7. The drilling fluid sample slides down along the micro-convex glass plate under the action of gravity to complete the natural flattening, that is, the sampling operation is completed.

[0046] The drilling fluid image acquisition operation status of the device is as follows Figure 6 and Figure 7After the device completes the sampling operation, the computer 34 issues a series of instructions through the intelligent control unit 19 to control the reduction motor 1 23 to drive the mechanical arm component 1 21 to rotate counterclockwise by 90 degrees, the reduction motor 2 24 and the reduction motor 3 4 to drive the mechanical arm component 2 20 and the mechanical arm component 3 8 to rotate, and the reduction motor 3 4 drives the telescopic shaft 9 to telescopic movement. The three actions cooperate to ensure that the sample glass plate 7 holding the drilling fluid sample is placed at the test position of the test frame 11, and the sample glass plate 7 is located in the groove at the center of the limit lower baffle 26, the glass plate and the center point of the camera lens are located on the same plumb line, and the sample glass plate 7 is always in a horizontal state during the entire rotation and telescopic process of the mechanical arm. Next, the computer 34 transmits instructions through the intelligent control unit 19 and the control harness 5, driving the liftable limit upper baffle 14 to drive the retractable light shielding tube 13 to move downward to the test position along the lift sliding guide rail 50, and the annular boss in the middle position of the liftable limit upper baffle 14 contacts the outer groove of the sample glass plate 7, thereby completing the fixation of the sampler together with the limit lower baffle 26, and forming a closed space with the retractable light shielding tube 13, the camera lens, and the sample glass plate 7 to form a good exposure environment. After that, the computer 34 controls the movement of the light source module through the control module of the test frame 11, and the instructions are transmitted through the control harness 5. The light source module is rotated by the rotating motor 38 fixed to the front end of the support arm to rotate the white light source 37 to the right below the test position, ensuring that the light source, the sample glass plate 7, and the center point of the lens are on the same plumb line. After that, turn on the light source and the high-definition camera 12 to complete the photo taking. After the white light source 37 is finished shooting, the light source is turned off, the motor 1 38 is rotated to reset the white light source 37, the motor 2 39 is rotated to rotate the ultraviolet light source 17 to just below the test position, the light source and the high-definition camera 12 are turned on to complete the shooting, and after the shooting is completed, the light source is turned off, and the motor 2 39 is rotated to reset the ultraviolet light source 17. The image information produced by the shooting is transmitted to the data acquisition unit 3 in real time. The image acquisition state is installed to obtain the white light source picture and the fluorescent picture to illustrate. If only the white light source picture is obtained, the operation of rotating and resetting the ultraviolet light source 17 does not exist. If only the fluorescent picture is obtained, the operation of rotating and resetting the white light source 37 does not exist. The relevant commands can be customized in the computer 34.

[0047] The cleaning and drying status of the device is as follows: Figure 8 and Fig. 9As shown. The device component that needs to be cleaned and dried is the sample glass plate 7, the purpose is to clean the drilling fluid and other dirt on the sampling plate after the image acquisition is completed, and use air to dry it so as to carry out the next set of sampling operations. Specifically, after the image acquisition is completed, the computer 34 sends a series of instructions through the intelligent control unit 19, the light source control system turns off the light source and completes the reset, the liftable limit upper baffle 14 drives the retractable light shielding tube 13 to rise and move to the standby position, the telescopic shaft 9 contracts to move the sample glass plate 7 out of the test position of the test frame 11, the reduction motor 1 23 controls the mechanical arm component 1 21 to rotate 180° clockwise, the reduction motor 2 24 and the reduction motor 3 4 cooperate to drive the mechanical arm component 2 20 and the mechanical component 3 8 to rotate to place the sample glass plate 7 into the cleaning and drying unit, and make the sample glass plate 7 located in the ultrasonic cleaner 27, the dryer 29 The sliding guide controller 31 on the upper part drives the horizontal sliding guide 41 to move and then close the dryer cover 55, and start the ultrasonic cleaner 27 to clean the drilling fluid and other dirt on the sample glass plate 7. After cleaning, the ultrasonic cleaner 27 is closed, and the reduction motor 3 4 drives the telescopic shaft 9 to contract and move the sample glass plate 7 to the dryer 29. The dryer 29 is turned on to dry the sample glass plate 7. During the drying process, air is introduced through the air inlet, and the cleaned sample glass plate 7 is dried by high-speed airflow. The air flow and steam are circulated and discharged through the return air port. During the entire cleaning and drying process, it is ensured that the inside of the test device box 1 remains in a windless and clean state. After the cleaning and drying is completed, the air inlet is closed, the sliding guide controller 31 on the dryer drives the horizontal sliding guide 41 to move and then open the dryer cover 55, the reduction motor 1 23, the reduction motor 24, and the reduction motor 3 4 drive the mechanical arm component 1 21, the mechanical arm component 20, and the mechanical arm component 3 8 to rotate, and the reduction motor 3 4 drives the telescopic shaft 9 to extend, and the sampler glass plate 7 is kept horizontally placed directly below the sampling port 54, and the sampler outlet is directly opposite to the center point of the sampler glass plate 7, preparing for the next set of sampling operations. In addition, after the sampler glass plate 7 is removed from the cleaning and drying device, the sliding guide controller 31 on the dryer 29 drives the horizontal sliding guide 41 to move and close the dryer cover 55.

[0048] The three operating states of the device, namely, liquid sampling, image acquisition, and cleaning and drying, are all completed under the instructions of the computer 34 and the intelligent control unit 19. The three operating states are coordinated with each other. After being completed in sequence, one set of tests is completed, and the relevant actions of the second set of tests are quickly started, and the cycle is repeated to achieve the purpose of continuous detection.
