Technical Field
The utility model relates to an used degasser in oil field logging scene is applicable to various types of drilling environment.
Background
With continuous deepening of oil exploration and development, the requirement of a logging site on a degasser (used for collecting formation gas in drilling fluid) is higher and higher, the traditional electric degasser has errors in gas collection accuracy due to the limitation of the traditional electric degasser and the difference of manual operation in the logging process, and if monitoring is not timely, the pipeline of the electric degasser is easily blocked or gas cannot be pumped, so that the discovery of oil gas display is influenced.

In order to achieve the above object, the present invention provides a floating ball type pneumatic degasser, comprising a floating ball, a pneumatic motor, an air compressor, a pressure reducing valve degasser and an annular guiding device;
the air compressor is connected with the pneumatic motor through a pressure reducing valve and provides pressure for the pneumatic motor; blades are arranged in the pneumatic motor and drive a stirring rod in the degasser to stir; a plurality of floating balls are arranged on the outer side of the cylinder of the deaerator, and the bottom surfaces of the floating balls are parallel to the bottom surface of the deaerator; the top end of the degasser is provided with a gas collecting cylinder, and the position of the gas collecting cylinder is provided with an annular guide device.
Preferably, the degasser is provided with a plurality of four symmetrically-positioned floating balls on the outer side of the cylinder, and the degasser floats on the drilling fluid surface through the floating balls.
The utility model discloses following beneficial effect has: the floating ball pneumatic degasser avoids the danger that an electric spark is easy to generate when a motor is used, is safer and more reliable, reduces the volume and the weight of the degasser, and provides necessary conditions for the degasser to float on the liquid level of a drilling well. The floating balls symmetrically arranged on the outer side of the degasser can increase the buoyancy of the degasser, so that the degasser floats on the drilling liquid level, and the draft stability of the degasser is ensured.
Description of the drawings:
fig. 1 is a schematic structural view of the floating ball type pneumatic degasser of the present invention.
Wherein: 1-floating ball; 2-a pneumatic motor; 3-an air compressor; 4-a pressure reducing valve; 5-a degasser; 6-ring guide.
The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1, the utility model provides a floating ball type pneumatic degasser, it includes floater 1, pneumatic motor 2, air compressor 3, relief pressure valve 4, degasser 5, annular guider 6. The air compressor 3 is connected with the pneumatic motor 2 through a pressure reducing valve 4, and the air compressor 3 provides pressure for the pneumatic motor 2; blades are arranged in the pneumatic motor 2 and drive a stirring rod in the degasser 5 to stir; a plurality of floating balls 1 are arranged on the outer side of the cylinder of the deaerator 5, and the bottom surfaces of the floating balls 1 are parallel to the bottom surface of the deaerator 5; and the top end of the degasser 5 is provided with a gas collecting cylinder, and the position of the gas collecting cylinder is provided with an annular guide device 6.
The degasser is characterized in that a plurality of four symmetrical floating balls 1 are arranged on the outer side of a cylinder of the degasser, and the degasser floats on the drilling liquid level through the floating balls 1.
The pneumatic motor in this embodiment enables the stirring rod of the deaerator to stir by vibration, and is small in size and light in weight. The annular guide device can effectively control the oscillation of the degasser in the floating process. The pressure reducing valve can control the pressure of the compressed air delivered by the air compressor.
The floating ball type pneumatic degasser provided by the embodiment reduces the pressure of the compressed air delivered by the air compressor to a proper pressure through the pressure reducing valve before the compressed air enters the pneumatic motor. The rotation of the blades in the air motor causes the stirring rod in the degasser to stir. Four floating balls are symmetrically arranged on the outer side of the degasser, and the annular guide device can effectively control the swing of the degasser in the floating process. The degasser can stably float on the liquid level of the drilling fluid, so that the draft of the degasser is ensured to be stable.
The working principle of the pneumatic degasser requires that the drilling fluid be stirred up in the gas degassing cylinder and overflow from the outlet, the higher the pressure of the air source, the higher the rotation speed of the stirring rod, but if the rotation speed of the stirring rod is too high, the drilling fluid will be stirred up to the top of the degassing cylinder and then enter the sample gas pipeline. To prevent this, the maximum pressure of the compressed air supplied to the air motor must not exceed 0.4MPa to maintain the speed of the stirring rod at about 800 rpm. Because the pneumatic motor has small volume and light weight, and four floating balls are symmetrically arranged on the outer side of the degasser, the degasser can float on the liquid level of the drilling fluid, thereby ensuring the stable draft of the degasser.
The floating ball type pneumatic degasser is safer and more portable by changing the prior motor into a pneumatic motor under the condition of not changing the degassing principle of the degasser. After the floating ball is installed, the structure is simple, the cost is low, the maintenance and the use are easy, the labor intensity is reduced, and the working efficiency is improved.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
