[0002] Oil and gas exploration refers to geological surveys, geophysical exploration, drilling and related activities to identify exploration areas and find out oil and gas reserves. It is the first key link in oil and gas production. The principles used include "seismic stratigraphy" and "numerical simulation technology", and the methods adopted include "seismic exploration" and "gravity exploration". In the process of oil and gas exploration, drilling work is required to be carried out according to the stratigraphic positions and depths of geological designs. Therefore, in order to intuitively study the underground structure and rock deposition environment and understand the properties of the fluids therein, coring tools are usually sent into the well to drill out rock samples to measure various properties of the rocks.

[0017] S2. Prepare for adjustment

[0018] After the S step is fixed, the hydraulic telescopic rod is used to drive the placement block and the slider to slide on the surface of the adjustment frame, so that the drilling rig body set on the surface of the slider can be moved synchronously. The horizontal movement adjustment is used so that the position of the drilling rig body can also be adjusted after the position of the adjustment frame is determined. In the process of the hydraulic telescopic rod pushing the placement block and the slider to slide on the surface of the adjustment frame, the positive and negative racks above the rotating gear drive the rotating gear to rotate, thereby causing the positive and negative racks below to move in opposite directions.

Use the drill rod to break the exploration surface and allow soil and rock to enter the inside of the drill rod to realize the exploration coring process;

[0021] S4, core removal

[0022] After the coring is completed, the exploration push rod is used to drive the adjustment frame and the drilling rig body to rise on the surface of the mobile frame, and then the micro push rod is used to drive the buckle seat to rise. The buckle seat is in the shape of a chuck. When the buckle seat rises away from the baffle seat, the gap at the outer edge of the baffle seat leaks out. At this time, the vibrator is turned on to vibrate the baffle seat to expand the gap and the pneumatic push rod is used to push the baffle seat to take out the core inside the drill pipe to complete the coring work.

[0023] The present invention provides a coring drill rig and a coring method for oil and gas exploration and development, which have the following beneficial effects: the coring drill rig and the method for oil and gas exploration and development, by adopting a mutually coordinated arrangement between a plurality of components, can not only use a hydraulic telescopic rod to push the main body of the drill rig to move horizontally to adjust the exploration and coring position after the position of the adjustment frame is determined, but does not need to frequently adjust the position of the entire device, and uses a counterweight system to always maintain the stability of the device before and after adjustment, further improving the working stability of the device, and uses a soil withdrawal component to facilitate the core withdrawal operation after coring, which is convenient for users to use, and uses a fixed-point component to assist the main body of the drill rig in finding a point for fixed-point exploration;

[0024] 1. The present invention uses the mutual coordination between the auxiliary components and the drilling rig body, and uses the hydraulic telescopic rod to push the placement block and the slider to slide on the surface of the adjustment frame, so that the drilling rig body set on the surface of the slider can be moved synchronously. By using horizontal movement adjustment, the position of the drilling rig body can also be adjusted after the position of the adjustment frame is determined, so that there is no need to frequently adjust the position of the entire equipment, which is convenient for users to use.

[0025] 2. The present invention sets up auxiliary components. When the hydraulic telescopic rod pushes the placement block and the slider to slide on the surface of the adjustment frame, the upper positive and negative racks drive the rotating gear to rotate, thereby causing the lower positive and negative racks to move in opposite directions. After the slider moves, the connecting block moves synchronously, thereby pushing the placement seat out. The counterweight block at the bottom of the placement seat can neutralize the gravity of the drilling rig body after horizontal movement, thereby improving the stability of the equipment during operation.

[0026] 3. The present invention uses a micro push rod to drive the buckle seat to rise through the mutual coordination between the soil withdrawal component and the drill pipe. The buckle seat is in the shape of a chuck. When the buckle seat rises away from the baffle seat, the gap at the outer edge of the baffle seat leaks out. At this time, the vibrator is turned on to vibrate the baffle seat to expand the gap and the pneumatic push rod is used to push the baffle seat to take out the core inside the drill pipe, thereby completing the coring work and being convenient for users.

[0027] 4. The present invention sets a fixed-point component, in which a sliding frame is connected to the bottom of a mobile frame. A telescopic push rod is used to push the slide and the fixed-point frame to move along the surface of the sliding frame to determine the position of exploration and coring. Subsequently, a driving motor is turned on to drive the meshing gear and the fixed-point drill bit to pre-drill holes at the exploration position to achieve fixed-point exploration.

Fixed-point exploration The telescopic push rod (902) is used to push the slide seat (903) and the fixed point frame (904) to move along the surface of the slide frame (901) to determine the location of the exploration coring, and then the driving motor (908) is turned on to drive the meshing gear (907) and the fixed point drill bit (906) to pre-drill a hole at the exploration location to achieve fixed point exploration; S2. Prepare for adjustment After the positioning in step S1, the hydraulic telescopic rod (8) is used to drive the placement block (204) and the slider (205) to slide on the surface of the adjustment frame (201), so that the drilling rig body (3) set on the surface of the slider (205) can be moved synchronously. By using horizontal movement adjustment, the position of the drilling rig body (3) can also be adjusted after the position of the adjustment frame (201) is determined. In the process of the hydraulic telescopic rod (8) pushing the placement block (204) and the slider (205) to slide on the surface of the adjustment frame (201), the positive and negative racks above the gear (202) are rotated. (203) drives the rotating gear (202) to rotate, thereby causing the positive and negative racks (203) below to move in opposite directions, and then after the slider (205) moves, the connecting block (207) moves synchronously, thereby pushing out the placement seat (208), using the counterweight block (209) at the bottom of the placement seat (208) to neutralize the gravity of the drilling rig body (3) after the horizontal movement, and using the infrared laser generator (905) to determine the position of the drilling rig body (3), so that the drilling rig body (3) stays directly above the fixed-point frame (904) to prepare for coring exploration; S3. Drive Exploration The drilling rig body (3) is opened to drive the drill rod (4) to rotate, and the exploration push rod (11) is used to push the adjustment frame (201) and the drilling rig body (3) to slide downward on the surface of the mobile frame (1), and the guide rod (10) is used to improve the stability of the equipment after movement. The drill rod (4) is used to break the exploration surface, and soil and rock are allowed to enter the interior of the drill rod (4), thereby realizing the exploration coring process; S4, core removal After coring is completed, the exploration push rod (11) is used to drive the adjustment frame (201) and the drilling rig body (3) to rise on the surface of the mobile frame (1), and then the micro push rod (503) is used to drive the buckle seat (502) to rise. The buckle seat (502) is in the shape of a chuck. When the buckle seat (502) rises away from the baffle seat (501), the gap at the outer edge of the baffle seat (501) leaks out. At this time, the vibrator (504) is turned on to vibrate the baffle seat (501) to expand the gap, and the pneumatic push rod (505) is used to push the baffle seat (501) to remove the core inside the drill pipe (4), thereby completing the coring work.
