Well cementation mud flow meter device

Abstract

The invention discloses a well cementation mud flow meter device which is applied to the field of well cementation tools. The well cementation mud flow meter device comprises a flow meter body, a union nut, a sensor, an upper flange plate, a sensor base, a lower flange plate, an impeller and a union connector. The two ends of a cement paste pipeline are respectively connected with the flow meter body through the union nut and the union connector, the lower flange plate is welded in the middle of the flow meter body, the sensor base is installed inside the lower flange plate, and the impeller is installed on the lower portion of the sensor base. The impeller is in a disc shape, an axis of the impeller is vertically arranged on an axis of the flow meter body, the sensor base is fixed on the lower flange plate through the upper flange plate, and the sensor is installed inside the upper flange plate. According to the well cementation mud flow meter device, the union nut and the union connector are used for connecting, the impeller is installed in the tangential direction, the well cementation mud flow meter device can monitor the flow value of cement paste in real time under the high pressure environment, the hidden danger that an existing turbine is blocked easily is eradicated, the metering precision of a flow meter is improved, and the safety level of pressure is increased.

Description

technical field [0001] The invention relates to a cementing mud flowmeter device in the field of cementing tools. Background technique [0002] During the cementing operation, the cement truck transports the cement slurry into the annular space between the downhole casing and the wellbore through pressurization, so that the drilled oil well is reinforced and cannot collapse. In cementing operations, the accuracy of cement slurry injection is the lifeline to ensure the quality of cementing. If the measured value of cement slurry is lower than the actual operating value, it will cause overflow of cement slurry, which will cause hidden dangers to the final bumping pressure and equipment safety; if the measured value of cement slurry is higher than the actual operating value, insufficient cement slurry will be added Cavities are formed in the eye annulus, failing to meet the cement slurry cementation index required by the cementing technology, which will lead to the collapse of...

AI Technical Summary

Problems solved by technology

When there are sundries such as plastic cloth in the cement slurry, it is easy to wind up on the blade, causing the blockage of the flow meter, interrupting the cementing and even causing accidents

In addition, the current flowmeter still has the same caliber as the cement truck pipeline, and the pressure of the cement injection slurry in each well needs to be adjusted according to the depth of the well, which leads to the insufficient pressure level of the original flowmeter and potential safety hazards.
