Embodiment Construction

[0015] The method and system of the present invention will now be 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.

[0016] Now turning to the attached image, figure 1 is a schematic illustration of a drilling rig 100 with an exemplary sample capture 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 riser 20 to vibrator 22, from vibrator 22 to mud pit 24, from mud pit 24 to mud pump 26, and from mud pump 26 back to the standpipe. pipe or rig 20. As shown in this figure, a samp...

Abstract

A sample catching system for cleaning a drilling fluid in a drilling operation includes a first line having a first entrance valve configured to allow the drilling fluid to flow into the first line, afirst chemical sensor for measuring the amount of hydrogen sulfide of the drilling fluid in the first line, and a first sample catch valve configured to allow the drilling fluid to flow out of the first line. The system also includes a second line having a second entrance valve configured to allow the drilling fluid to flow into the second line, a sample catch pump, and a controller configured todetermine the amount of hydrogen sulfide is above a predetermined threshold value, and open the second entrance valve to divert drilling fluid intake from the first line to the second line, and closethe first entrance valve to stop the drilling fluid from entering the first line.

Description

technical field [0001] The present invention relates generally to the automation of drilling operations, and more particularly to methods and systems for automatic cleaning or sample capture of drilling fluids during drilling operations. Background technique [0002] Drilling wells in hydrocarbon-bearing subterranean formations to produce hydrocarbons from the formations generally involves the use of drilling equipment and drilling fluids. Drilling equipment usually consists of a drill bit mounted on a string of hollow steel pipes. The hollow tube is typically used to rotate the drill bit to enable the bit to cut into the formation. The hollow tube also serves as a conduit for pumping drilling fluid down to the bottom of the well, from where it rises to the surface via the annular space between the drill string and the well wall. Drilling fluids have many functions, one of the most important of which is to transport cuttings from the drill bit downhole up to the surface of...
