Speed oil filling device for pulse generator of wireless inclinometer and using method thereof

Abstract

The invention relates to a speed oil filling device for a pulse generator of a wireless inclinometer and a using method thereof, wherein the oil-filled device comprises a vacuum pump, an oil tank, an oil inlet pipeline and an oil outlet pipeline; the oil tank is internally provided with a suction pipe, an oil filling pipe and an oil charging pipe, wherein the suction pipe is connected with the vacuum pipe, and the communication is controlled by a third valve; the oil filling pipe is connected with the oil inlet pipeline, and the communication is controlled by a first valve; and the oil charging pipe is connected with the oil outlet pipeline, and the communication is controlled by a second valve; the lower end of the suction pipe is provided with a fourth valve for controlling the communication between the oil tank and the atmosphere; the ports of the oil inlet pipeline and the oil outlet pipeline are respectively provided with fast insertion type oil filling plugs; and each valve is in seal connection with the corresponding pipeline via a quick screwing type fast plug. The speed oil filling device provided by the invention has excellent sealing performance; a single-hole oil filling method or a double-hole oil filling method is provided; the air remained in an oil bag of the pulse generator is reduced as possible; and the oil is fast and conveniently filled in the pulse generator.

Description

technical field [0001] The invention relates to an oil filling device, in particular to a rapid oil filling device for a pulse generator of a wireless inclinometer while drilling (abbreviated as MWD) and a method for using the same. Background technique [0002] The wireless measurement-while-drilling instrument mainly transmits the downhole measurement data to the surface through the pulse generator. During the production process of the pulse generator, if the oil filling effect is not ideal, it will lead to poor signal transmission, especially when drilling deep wells. more obvious. The original pulse generator adopts the vacuum pressure oil method, but the sealing performance of the device is poor, especially at the oil-filled joint. It is often difficult to distinguish whether it is the problem of the pulse generator capsule due to the air leakage of the joint, and the original design of the filling nozzle is low from the oil tank. Recently, residual oil deposits easily...

Problems solved by technology

[0002] The wireless measurement-while-drilling instrument mainly transmits the downhole measurement data to the surface through the pulse generator. During the production process of the pulse generator, if the oil filling effect is not ideal, it will lead to poor signal transmission, especially when drilling deep wells. more obvious

The original pulse generator adopts the vacuum pressure oil method, but the sealing performance of the device is poor, especially at the oil-filled joint. It is often difficult to distinguish whether it is the problem of the pulse generator capsule due to the air leakage of the joint, and the original design of the filling nozzle is low from the oil tank. Nearby, residual oil deposits easily enter the pulse generator oil bag through the oil filling pipe and cause losses

The disadvantages of the existing oil filling device of the pulse generator are: the valves are easy to leak, the joint between the oil tank mouth and the base is not well sealed, the oil filling, the exhaust pipe is too simple, the oil filling method is single, and the joint operation is cumbersome and inconvenient, etc.
