Embodiment Construction

[0014] Combine below figure 1 A detailed description of a remote automatic ash supply control system:

[0015] Such as figure 1 Shown is a schematic diagram of a remote automatic ash supply control system. 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 at the equipment end feeds back the liquid level of the metering tank through the liquid level gauge 6 of the metering tank, and remotely controls the control box of the submersi...

Abstract

The invention belongs to the field of petroleum equipment, and particularly relates to full-automatic intelligent remote controlled well solidifying equipment, and to a remote automatic cement supplying control system for well solidifying equipment. The remote automatic cement supplying control system comprises a control unit, an air compressor, a cement tank and a cement valve. The remote automatic cement supplying control system is characterized in that the control unit comprises an equipment end operating screen, an equipment end PLC processor, a remote control operating screen and a remotecontrol PLC processor; the equipment end operating screen, the equipment end PLC processor, the remote control operating screen and the remote control PLC processor are connected through netting twines; the equipment end PLC processor can remotely control a remote control module for starting and stopping the air compressor, thereby controlling the air compressor through the remote control module;after the air compressor is started, high-pressure air is discharged to the cement tank; the equipment end PLC processor automatically calculates a required cement supplying amount through a preset density of the well solidifying equipment; through comparing the calculated cement supplying amount with a current acquired cement supplying amount, proportion controlling and adjustment of the cementvalve are performed; and furthermore the cement supplying amount of the equipment is controlled.

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 ash supply 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 cementing operations, the hig...
