Technical Field

[0001] The utility model relates to the technical field of oil exploration, in particular to a suspended degassing device for oil exploration. Background Art

[0002] A Chinese patent with the publication number CN107246253A proposes a suspended degassing device for oil exploration, belonging to the technical field of oil exploration. Its structure includes a floating barrel and a degassing chamber. The floating barrel is set as a cylindrical ring-shaped barrel with both the upper and lower end faces closed and both the annular inner and outer walls closed. A middle hole is opened in the center of the floating barrel; the degassing chamber is set as a cylindrical barrel in the vertical direction. The degassing chamber penetrates the floating barrel through the middle hole of the floating barrel, and a sealed seamless welded fixed connection is provided between the inner wall of the middle hole of the floating barrel and the outer wall of the degassing chamber; a slope baffle is arranged in the upper space of the inner cavity of the degassing chamber. The slope baffle divides the top space of the degassing chamber into a gas storage chamber. A motor is fixedly configured at the center of the top surface of the degassing chamber, and the motor is hard-connected to output and drive a stirring shaft. This suspended degassing device for oil exploration solves the problem that traditional equipment cannot achieve real-time continuous and uninterrupted degassing, realizes continuous, automatic and efficient degassing of drilling fluid, and achieves truly uninterrupted degassing.

[0003] However, in actual use, the drilling fluid is relatively viscous, and a single stirring rod cannot fully stir the drilling fluid. Therefore, this device has certain usage defects, that is, the stirring rod cannot fully stir the drilling fluid, resulting in insufficient exhaust. Content of the Utility Model

[0004] In order to overcome the defect that the existing degassing device cannot fully stir the drilling fluid, resulting in incomplete exhaust, the utility model provides a suspended degassing device for oil exploration with a stronger stirring function.

[0005] The technical solution is: a suspended degassing device for oil exploration, including a floating barrel. The floating barrel is a closed cylindrical shape. A through cylindrical degassing chamber is connected in the middle of the floating barrel. A servo motor is fixed at the top of the degassing chamber. The output end of the servo motor is connected with a rotating shaft. The rotating shaft is rotatably arranged in the degassing chamber. An activity groove is opened on the side surface of the rotating shaft. A stirring rod passes through the activity groove and is connected to the rotating shaft. It also includes a mounting plate and a fixing rod. The mounting plate is fixedly connected to the inner wall of the degassing chamber. The fixing rod is fixedly connected to the mounting plate. The fixing rod is located inside the rotating shaft. An undulating groove is opened on the fixing rod. A slider is fixedly connected to the end of the stirring rod. The slider is limited to slide in the groove.

[0006] Furthermore, it also includes a support rod. A threaded hole is opened on the side surface of the stirring rod. The support rod is fixed in the threaded hole by threading.

[0007] Furthermore, a flat surface is opened on the support rod.

[0008] Furthermore, it also includes a protective plug, and the protective plug can block the threaded hole.

[0009] Further, it further includes a limiting block. The inner end of the support rod is fixedly connected with the limiting block, and the limiting block limits the length of the support rod extending into the stirring rod.

[0010] Further, it further includes a waterproof ring. The waterproof ring is arranged at the bottom of the rotating shaft, and the waterproof ring seals the bottom of the rotating shaft.

[0011] Further, it further includes a rubber block. The rubber block is connected to the inner end of the stirring rod, and the rubber block seals the movable groove.

[0012] The beneficial effects are as follows: When the servo motor is turned on to drive the rotating shaft to rotate continuously, the rotating shaft will drive the stirring rod to rotate, and the stirring rod will agitate the drilling fluid in the degassing chamber, so as to efficiently export the air in the drilling fluid. A groove is provided in the middle of the fixed rod, and the undulating groove can push the stirring rod up and down reciprocally, so as to optimize the stirring path of the stirring rod and improve its stirring effect.
