Embodiment Construction

[0014] Combine below figure 1 Explain in detail the remote automatic displacement and density automatic control system:

[0015] Such as figure 1 Shown is a schematic diagram of remote automatic displacement and density automatic control. The remote control operation screen 1 and the remote control PLC processor 2 are installed in the remote control box, and the two are connected through a network cable. The remote control PLC processor 2 in the remote control box is connected to the device-side PLC processor 4 through a network cable, so that the remote control box can operate and control the device-side PLC processor 4 through the remote control operation screen 1 . The device-side PLC processor 4 is connected to the device-side operation screen 3 through a network cable for data display and device operation. The PLC processor 4 of the equipment side, the ECU of the engine 6, and the TCM of the gearbox 7 carry out protocol conversion between PROFIBUS and CAN communication...

Abstract

The invention belongs to the field of oil equipment, and particularly relates to full-automatic intelligent remote-control cementing equipment. A long-distance automatic displacement and density automatic control system being used for the cementing equipment is characterized in that the long-distance automatic displacement and density automatic control system at least comprises a power unit and acontrol unit. The power unit comprises an engine, a gearbox and a plunger pump, and the control unit comprises a device operation screen, a device PLC processor, a remote-control operation screen, a remote-control PLC processor and an Anybus module. Operating personnel write in a set displacement set value or a set density value on the remote-control operation screen or the device operation screen, after the device PLC processor reads the set displacement information, a set gear needed by the current set displacement and the accelerator position are calculated through program internal calculation, so that the rotating speed of the engine and the gears of the gearbox are controlled, finally the long-distance automatic displacement and density automatic control system is used for controllingthe input rotating speed of the plunger pump, and the purpose of controlling the discharging displacement of the plunger pump is achieved.

Description

technical field [0001] The invention belongs to the field of petroleum equipment, and in particular relates to a fully automatic intelligent remote-controlled cementing equipment, which is used for a remote automatic displacement and density automatic control system used in the cementing equipment. Background technique [0002] As cementing equipment is more and more widely used in well site operations at home and abroad, the complexity and harshness of the working conditions of the cementing operation make the cementing equipment more and more intelligent and centralized control of the operation during the operation process. high. At present, the cooperation between the equipment of the whole well site in the cementing operation is relatively poor, and the degree of automation is low. The traditional cementing operator has been standing on the equipment, only one step away from the plunger pump and high-pressure manifold. When performing some deep high-pressure well cemen...
