It is the first key step in oil and gas production, aiming to identify favorable areas for oil and gas accumulation, locate reservoirs, and determine the size of oil and gas fields, as well as the characteristics and production capacity of oil and gas strata.

[0003] In the large sandstone layer of the Guantao Formation, the sandstone particle size is relatively large. The gas path probe is very easy to get stuck during use, resulting in blockage of the gas path probe. If the torque limiter loses its function, the steel wire will be damaged, resulting in distortion of gas data recording, thereby reducing the use effect and service life of the gas path probe. Therefore, an anti-blocking mechanism for the external gas path probe of comprehensive logging for petroleum exploration is proposed.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the anti-blocking mechanism of the external gas path probe of the integrated logging for oil exploration includes a gas path pipe 1 and a gas path probe 2 installed at the end thereof, and also includes: a connection anti-blocking mechanism for preventing the gas path probe 2 from being blocked and avoiding the gas path probe 2 from being blocked. The connection anti-blocking mechanism includes a plurality of first connection plates 3 connected to the outer wall of the gas path pipe 1, a filter 301 is connected between the plurality of first connection plates 3, a plurality of second connection plates 302 are fixedly installed on the outer wall of the filter 301, a plurality of buoyancy blocks 303 are fixedly installed between the plurality of second connection plates 302, a plurality of support rods 304 are fixedly connected to the bottom of the buoyancy blocks 303, and a plurality of support rods 304 are fixedly connected to the bottom of the plurality of support rods 304. A support base 305 is fixedly connected to the bottom of the plurality of support rods 304.

[0024] The present invention further specifically describes that the buoyancy of the buoyancy block 303 is greater than the buoyancy of the gas path probe 2, the buoyancy block 303 is made of aluminum alloy, the support frame 305 is made of stainless steel pipe, the filter screen 301 is made of stainless steel, the buoyancy block 303 is sleeved on the outer wall of the filter screen 301, and the filter screen 301 is sleeved on the outer walls of the gas path pipe 1 and the gas path probe 2;

[0025] As can be seen from the above, by utilizing the function of the filter 301, the adhesion of sandstone particles to the outer wall of the gas path probe 2 can be reduced when the gas path probe 2 is in use, and the blockage of the gas path probe 2 is correspondingly reduced. At the same time, by utilizing the function of the buoyancy block 303, the gas path probe 2 can float up and down according to the liquid level, which can effectively prevent the probe from being buried by sand or evacuated, thereby improving the use effect and service life of the gas path probe 2.

[0026] Preventing the gas path probe 2 from being blocked has the following benefits:

[0027] The gas path probe 2 plays a key role in gas detection and flow measurement. If the outer wall of the gas path probe 2 is blocked, it will affect the normal flow and diffusion of the gas, resulting in inaccurate measurement data. Anti-blocking treatment can ensure that the outer wall of the probe remains clean and unobstructed, thereby improving the accuracy and reliability of the measurement.

[0028] By performing anti-clogging treatment on the gas path probe 2, the occurrence of blockage can be effectively reduced, the failure rate of the gas path probe 2 can be reduced, and its service life can be extended. This not only reduces the frequency and cost of replacing the gas path probe 2, but also improves the overall stability and reliability of the equipment;

[0029] In industrial applications, by performing anti-clogging treatment on the gas path probe 2, it can be ensured that the gas path probe 2 can continuously and accurately monitor gas parameters, and detect and handle abnormal situations in a timely manner, thereby ensuring the safe operation of the system; anti-clogging treatment can improve the reliability of the gas path probe 2, so that it can continue to work under harsh environmental conditions. For example, in some harsh environments such as high temperature, high humidity, and high dust, the outer wall of the probe is prone to blockage.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a plug-in mounting mechanism is provided on the first connecting plate 3 for quickly disassembling and installing the connection anti-blocking mechanism. The plug-in mounting mechanism includes a sliding cavity 4 provided inside the first connecting plate 3. Two tension springs 401 are connected to the inner wall of the sliding cavity 4. An L-shaped slide 402 is fixedly connected between the two tension springs 401. A square slide 403 is provided on the first connecting plate 3. The top of the L-shaped slide 402 extends to the outside of the first connecting plate 3 through the square slide 403. The outer wall of the L-shaped slide 402 and the inner wall of the square slide 403 are slidingly fitted. One end of the L-shaped slide 402 slides and extends to the outside of the first connecting plate 3. A plug-in interface is provided on the outer wall of the gas line tube 1. The L-shaped slide 402 and the plug-in interface are correspondingly slidably plugged in. The first connecting plate 3 and the gas line tube 1 are plugged and fixed through the L-shaped slide 402. The first connecting plate 3 is fixedly mounted on the inner wall of the filter screen 301.

[0031] As can be seen from the above, when the staff connects the anti-blocking mechanism to the gas pipe 1, they slide the L-shaped slide plate 402 to the outside of the first connecting plate 3 so that one end corresponds to the plug-in port, and then slide the L-shaped slide plate 402 into the plug-in port on the outer wall of the gas pipe 1, so that the filter 301 can be installed and fixed to the gas pipe 1;

[0032] When disassembling the connection anti-blocking mechanism, slide the L-shaped slide plate 402 to disengage the L-shaped slide plate 402 from the plug interface of the outer wall of the gas pipe 1, and then remove the connection anti-blocking mechanism;

[0033] By setting up the above-mentioned technical solution, the sliding plug-in function between the L-shaped slide plate 402 and the plug interface is utilized to simplify the operation of connecting and fixing the anti-blocking mechanism to the air pipe 1, thereby improving the efficiency of the staff in installing and using the anti-blocking mechanism.

[0034] Furthermore, this design application is used to prevent the external gas path probe 2 of comprehensive logging for oil exploration from being blocked. By utilizing the function of the filter 301, the adhesion of sandstone particles to the outer wall of the gas path probe 2 can be reduced when the gas path probe 2 is in use, thereby correspondingly reducing the blockage of the gas path probe 2. At the same time, by utilizing the function of the buoyancy block 303, the gas path probe 2 can float up and down according to the liquid level, which can effectively prevent the probe from being buried in sand or evacuated, thereby improving the use effect and service life of the gas path probe 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
