Problems solved by technology
A typical problem that arises during the operation of a hydraulic restrictor is that relatively large solid particulate matter tends to restrict or plug the restrictor, making the restrictor's flow control irregular
In this case, the clogged screen may itself fail structurally and add particulate matter to the flow stream

Embodiment Construction
[0016] The method and system of the present invention are now described more fully hereinafter with reference to the accompanying drawings in which embodiments are shown. The methods and systems of the present invention may be in many different forms and should not be construed as limited to the illustrated embodiments set forth herein; The range fully conveys to those skilled in the art. Like numbers refer to like elements throughout.
[0017] Now turning to the attached image, figure 1 is a schematic illustration of a drilling rig 100 having an exemplary automated cleaning system 50 for cleaning drilling fluid during drilling operations in accordance with one or more exemplary embodiments of the present invention. During drilling operations, drilling fluid or drilling mud may be circulated from the flow lines of the drilling rig 20 to the vibrator 22, from the vibrator 22 to the mud sump 24, from the mud sump 24 to the mud pump 26, and from the mud pump 26 back to riser o...

An automatic cleaning system for cleaning drilling fluid during drilling operations, comprising a first pipeline, a second pipeline, an automatic cleaning pump operatively connected to the first pipeline and the second pipeline, and surrounding at least a portion of the first pipeline. An electromagnetic device, wherein the electromagnetic device is energized when drilling fluid passes through the first pipeline. An automatic cleaning pump is configured to receive drilling fluid from the first line or the second line and to remove metal particles from the drilling fluid. The system also includes a controller configured to determine a pressure differential in the pipelines, at least partially open the valve to divert drilling fluid introduced from one pipeline to the other pipeline, and close the first inlet valve to prevent entry of drilling fluid first pipeline.
Description
technical field [0001] The present invention relates generally to the automation of drilling operations, and more particularly to methods and systems for removing metal particles from drilling fluids. Background technique [0002] Hydraulic choke devices are commonly used in oil fields when drilling or treating wells. Herein, the term "hydraulic choke" is used to refer to situations where the device is used with various fluids such as drilling mud, brine, oil, gas, and other chemicals that can flow into or out of a well. "Hydraulic" here does not refer to a throttle actuation device. A hydraulic choke acts as a pressure relief valve for fluid flowing from the well. The pressure of the fluids discharged from the well flow control system must be significantly reduced for further processing and storage of these fluids. A typical problem that arises during operation of hydraulic restrictors is that relatively large solid particulate matter tends to restrict or plug the restri...
