Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a single-chip microcomputer-based mud return digital display. Background technique [0002] Single-chip microcomputer, also known as single-chip microcontroller, is not a chip that completes a certain logic function, but integrates a computer system into a chip. It is equivalent to a microcomputer. Compared with computers, single-chip microcomputers only lack I / O devices. Single-chip microcomputers have been used in a wide range of fields, such as smart instruments, real-time industrial control, communication equipment, navigation systems, and household appliances. [0003] The main purpose of measuring mud return flow, also known as mud outlet flow, is to predict whether there are abnormal phenomena such as well leakage or well kick, rather than measuring it as a hydraulic parameter. The sensors therefore detect relative changes in outlet flow, expressed as a percen...

Problems solved by technology

[0004] The baffle type is used to measure the mud return. On the one hand, the baffle is still fatigued by the impact of the mud for a long time. Even if the flow value is calibrated in the factory, the set point drift will occur.

On the other hand, the baffle-type measurement adopts the principle of contact measurement. The mud is easy to stick to the baffle, which affects the measurement accuracy and service life. The traditional mud return digital display instrument has cumbersome operation steps, which brings great inconvenience to the operator.
