Description

technical field

[0001] The invention relates to the field of petroleum equipment, and more specifically designs a near-distance full-process control system for well cementing equipment. Background technique

[0002] With the development of cementing technology, there is a requirement for close-range and long-distance control of cementing operations; traditional cementing equipment requires the operator to stand on the platform to operate, and notify the relevant water supply and ash supply through gestures or walkie-talkies , Butterfly valve opening or plug valve opening, etc., the labor intensity of personnel is relatively high, and more personnel are required to complete one operation; in addition, the cementing operation is a high-pressure operation, which makes the safety of the cementing operation unforeseen and complicated, often Operators need to take great risks to carry out cementing operations to ensure the smooth completion of cementing operations.
