Description

Technical Field

[0001] This invention relates to the field of automatic gas collection equipment technology, and in particular to a non-stirring, high-efficiency degassing device. Background Technology

[0002] In oil and gas exploration and development, gas logging is a logging method that directly measures the content of combustible gases in drilling fluid. Gas carried by the drilling fluid returning from the bottom of the well can be obtained from a degasser installed before a vibrating screen. Its composition and content are then detected and recorded to determine the activity of the oil and gas reservoir.

[0003] The degasser is located at the forefront of gas logging and is an essential piece of equipment for gas logging. Its performance directly determines the gas detection and analysis results. Traditional electric degassers have low degassing efficiency and cannot quantitatively degas, which directly affects the stability, accuracy, and continuity of logging data acquisition, impacting the accurate identification, interpretation, and evaluation of oil and gas reservoirs, and failing to meet the high-quality requirements of fine logging in exploration and development.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a non-stirred, high-efficiency degassing device. Summary of the Invention

[0016] Furthermore, the filter cartridge is divided into an outer filter cartridge and an inner conductive cartridge;

[0017] The spiral transmission shaft is located inside the transmission inner cylinder, and a spiral transmission impeller is arranged circumferentially on the spiral transmission shaft.

[0018] Furthermore, the upper part of the conductive inner cylinder is connected to a liquid outlet, and a drilling fluid flow measurement component is provided between the liquid outlet and the ultrasonic degasser.

[0031] The device of this invention changes the traditional stirring degassing to non-stirring degassing, and uses an ultrasonic degasser to achieve degassing of logging fluid, achieving the design goal of high-efficiency degassing.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] See Figure 1 As shown;

[0040] This embodiment discloses a non-stirring, high-efficiency degassing device, which includes:

[0041] A spiral fluid production unit located upstream of the process and used for continuous extraction of drilling fluid; and

[0042] An ultrasonic degasser 10 is located downstream of the spiral liquid collection mechanism and is connected to the spiral liquid collection mechanism via a pipeline.

[0043] The ultrasonic degasser 10 is equipped with multiple ultrasonic transducers 1004. The spiral fluid extraction mechanism extracts drilling fluid and transports it to the ultrasonic degasser 10 through pipeline. The ultrasonic degasser 10 breaks up the drilling fluid to release internal gas through the vibration of the multiple ultrasonic transducers 1004.

[0044] The degassed drilling fluid is pumped into a chromatograph for analysis and detection using a sample pump.

[0045] Specifically, this embodiment discloses a non-stirred high-efficiency degassing device, which consists of a spiral fluid extraction mechanism and an ultrasonic degasser 10. The device continuously extracts drilling fluid through the spiral fluid extraction mechanism, utilizing an internal stainless steel mesh filter design to prevent large rock cuttings from entering the delivery pipeline and causing blockages, thus ensuring the stability of the delivery system. In this embodiment, the high-frequency vibration of the ultrasonic transducer 1004 inside the ultrasonic degasser 10 causes gas in the drilling fluid to be extracted while it flows, and then sampled for detection by a chromatograph, thereby improving degassing efficiency.

[0046] Preferably, the spiral liquid collection mechanism of this embodiment includes a spiral conductive liquid collection cylinder 4; a filter cylinder located inside the spiral conductive liquid collection cylinder 4, and a spiral conductive shaft 404 extending axially from the filter cylinder;

[0047] An explosion-proof motor 3 is installed at the upper end of the spiral conduction liquid collection cylinder 4. The output end of the explosion-proof motor 3 is connected to the spiral conduction shaft 404. A spiral lifter 2 is provided at the upper end of the explosion-proof motor 3, and the spiral lifter 2 has a rotating handle 1 at the upper end.

[0048] In this embodiment, the filter cylinder is divided into an outer filter cylinder 401 and a conductive inner cylinder 402.

[0049] The spiral transmission shaft 404 is located inside the transmission inner cylinder 402, and a spiral transmission impeller 403 is arranged circumferentially on the spiral transmission shaft 404.

[0050] Secondly, in this embodiment, the upper part of the conductive inner cylinder 402 is connected to the liquid outlet 5, and a drilling fluid flow measurement component is provided between the liquid outlet 5 and the ultrasonic degasser 10.

[0051] The drilling fluid flow measurement component is connected to the outlet 5 of the spiral fluid production mechanism via a pipeline;

[0052] The drilling fluid flow measurement component is connected to the inlet 9 of the ultrasonic degasser 10 via a pipeline.

[0053] First, this embodiment further defines the structure of the spiral fluid production mechanism, which includes a spiral transmission fluid production cylinder 4, a filter outer cylinder 401, and a transmission inner cylinder 402. The stainless steel mesh structure of the filter outer cylinder 401 is used to remove rock cuttings and avoid pipeline blockage. Then, the drilling fluid is extracted from the transmission inner cylinder 402 by the spiral transmission shaft 404 and the spiral transmission impeller 403 and discharged from the outlet 5.

[0054] Preferably, the drilling fluid flow measurement component of this embodiment includes a drilling fluid flow meter 8 connected to the outlet 5 via a hose 6; the drilling fluid flow meter 8 is connected to the inlet 9 of the ultrasonic degasser 10 via the hose 6.

[0057] This embodiment further defines the composition of the ultrasonic degasser 10. Multiple ultrasonic transducers 1004 are arranged side by side inside the device housing. When the drilling fluid passes through the drilling fluid flow measurement component, it enters the device housing through the inlet. Under the action of the multiple ultrasonic transducers 1004, the drilling fluid is broken up by generating high-energy vibrations, and the gas contained inside is released. The gas is then pumped into a chromatograph for analysis and detection by a sample pump. The drilling fluid flows through the ultrasonic degassing chamber 1003 and then flows back to the drilling fluid pool, thus completing the degassing work.

[0058] To achieve device integration, the device in this embodiment also includes a mounting bracket 11;

[0059] A spiral liquid collection mechanism is arranged at one end of the mounting bracket 11, and an ultrasonic degasser 10 is arranged at the other end of the mounting bracket 11.

[0060] In the above technical solution, the non-stirring high-efficiency degassing device provided by the present invention has the following beneficial effects:

[0061] The device of this invention changes the traditional stirring degassing to non-stirring degassing, and uses an ultrasonic degasser 10 to achieve degassing of the logging fluid, achieving the design goal of efficient degassing, ensuring the authenticity and effectiveness of the full hydrocarbon composition in gas logging. This device is conducive to the application and promotion of gas collection and analysis technology in drilling and existing gas logging, and is beneficial to oil and gas show discovery and reservoir evaluation, promoting the standardization, modernization and intelligent development of gas logging operations.
