Description

Technical Field

[0001] The invention belongs to the technical field of oilfield logging, and in particular relates to oilfield logging equipment in high-cold areas. Background Art

[0002] Oilfield logging equipment is a tool used to detect and measure underground oil and gas reservoirs during oil exploration and development. It is generally composed of a logging winch, logging cable, logging head and various sensors. It detects and determines the thickness and location of oil and gas layers within the oil field by collecting and analyzing a variety of physical information in the oil well, and plays a vital role in oil exploration and development.

[0003] At present, the common oilfield logging setup mainly relies on the logging winch to release the logging cable during the exploration of oil wells, and the logging head moves under the action of gravity to enter the oil well for information collection. Although this method allows the logging head to move in the oil well, it is easily affected by the instability of the oil well bore during use, resulting in obstruction and jamming of the logging cable. At the same time, the logging cable will rub against the wall of the oil well during the falling of the logging head, especially in high-altitude and cold areas. The logging cable will adhere to the wall of the oil well under the condition of pressure difference adhesion, which makes the logging stability and reliability of the oilfield logging equipment poor.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0049] like Figures 2 to 8As shown, a pair of storage support rods 209 are slidably equipped with telescopic connecting rods 210, and the telescopic connecting rods 210 are hinged to the wheel frame 202. The telescopic connecting rods 210 play the role of connecting the wheel frame 202 and the storage support rods 209, and the wheel frame 202 is supported and limited by the telescopic connecting rods 210.

[0050] like Figures 2 to 3 As shown, a drive motor 211 is fixedly mounted on one side of the wheel frame 202, and the output shaft of the drive motor 211 is transmission-connected to the track wheel 203. The drive motor 211 provides power, and the track wheel 203 is rotationally driven by controlling the operation of the drive motor 211, so as to facilitate the control of the walking track 204 to move.

[0051] like Figures 7 to 10 As shown, a pair of expansion type anti-blocking mechanisms 3 are assembled at both ends of the fixed sleeve 201, and the expansion type anti-blocking mechanism 3 includes a fixed plate 301, which is fixedly assembled at one end of the fixed sleeve 201. The fixed plate 301 supports and limits the driving assembly plate 302.

The driving inner ring 305 plays the role of assembly limit for the driving assembly plate 302.

[0054] Specifically, a plurality of evenly distributed driving teeth are integrally formed on the outer side of the driving inner ring 305. The driving assembly plate 302 is driven and controlled by driving and controlling the driving teeth.

[0055] like Figures 9 and 10 As shown, the outer side of the driving inner ring 305 is meshed with a transmission gear 306. The driving inner ring 305 is driven and controlled by driving the transmission gear 306 to rotate.

The rotating motor 307 provides power, and the transmission gear 306 is rotationally driven by controlling the operation of the rotating motor 307, so as to facilitate the rotational driving of the driving inner ring 305.

[0057] Preferably, the outer sides of the driving motor 211 and the rotating motor 307 are both provided with insulating protective covers. The insulating protective covers can provide insulation protection for the driving motor 211 and the rotating motor 307, thereby improving the safety of the driving motor 211 and the rotating motor 307.

[0061] like Figures 9 to 11 As shown, a gas flow channel 309 is provided in the driving assembly plate 302, and the gas flow channel 309 is connected to the crushing receiving rod 303. Gas is transported into the crushing cone 304 through the gas flow channel 309, so that the crushing cone 304 is pneumatically controlled.

The delivery air pipe 310 serves to connect the delivery air pipe 310 with the air guide channel 309, so that the gas in the buffer airbag 308 is transported to the crushing cone 304 along the air guide channel 309 and the delivery air pipe 310.

[0063] During specific use, when the oil field logging equipment is used, the logging head 1 can be placed in the oil field wellway, and the piston block 207 and the piston rod 208 can be driven and controlled by controlling the air intake of the control cylinder 206. By controlling the movement of the limit slider 205, the wheel frame 202 can be unfolded under the action of the storage support rod 209 and the telescopic connecting rod 210, thereby playing a role in adjusting the position of the walking track 204.

[0064] Subsequently, the track wheel 203 can be driven to rotate by controlling the operation of the driving motor 211, so that the track wheel 203 drives the traveling track 204 to rotate, and the logging head 1 is moved in the oil field well through the rotation of the traveling track 204. During the movement, the logging cable 102 can be continuously released by controlling the operation of the logging winch 101.

[0065] In addition, during the movement of the limit slider 205, the buffer airbag 308 can be squeezed or stretched, and the gas in the buffer airbag 308 and the crushing cone 304 can be connected with the buffer airbag 308 under the action of the air guide channel 309 and the air delivery pipe 310, so that the extension state of the crushing cone 304 can be adjusted by squeezing or stretching the buffer airbag 308. At the same time, the transmission gear 306 can be driven to rotate by controlling the operation of the rotary motor 307, and the driving assembly plate 302 drives the crushing storage rod 303 and the crushing cone 304 to rotate under the meshing action of the driving inner ring 305 and the transmission gear 306, and the obstacles on the inner wall of the wellbore are crushed by the rotation of the crushing cone 304 and the crushing storage rod 303, thereby ensuring the movement stability of the logging head 1.
