GAS TRAP EXPANSION CHAMBER

摘要

The invention allows for the collection of formation gases by placement of an agitating pipe directly in the drilling fluid flow line; the pipe's opening cut at an angle so gas in the top half of the drilling fluid flow line will be collected and also analyzed, along with the gas agitated from the drilling fluid. An expansion chamber is disclosed which encourages the drilling fluid flow line to release the gas held within it, so sample testing of the gases is more accurate than it would be in the prior art.

主权项

1. An apparatus used to collect gas samples from a fluid line in which a mixture of liquids and gases may be flowing, comprising:
a. an Agitating Pipe—a pipe installed so that it extends perpendicularly down from the top of a fluid line wall, in which the lower end of the pipe is cut at an angle and length to fit inside the diameter of the fluid line, and the installed pipe is set so that it faces into the fluid flow, and the upper end of the pipe extends up to the exterior of the fluid line; b. a Gas Trap Expansion Chamber—an enclosed volume in which fluid from the Agitating Pipe flows through an Entrance Portal into the enclosed volume, through agitating elements which assists to release gas within the fluid before the fluid leaves the volume through a drain; and c. a Sample Tube—set in the top of the Expansion Chamber, taking gases released from the flow liquid from the Expansion Chamber.
