ABSTRACT:
This invention is a volatile hydrocarbon detector apparatus to continuously sample methane gas in an oil well drilling mud. The detector apparatus includes 1) a gas sampler assembly to gather the methane gas from the drilling mud; 2) a control module assembly to receive and amplify electrical signals from the gas sampler assembly; and 3) a recorder assembly to receive output electrical signals from the control module assembly.
The recorder assembly is of a conventional nature and operates to record on a paper roll the date, time of day and the amount of methane gas present in the drilling mud. The main novelty lies in the gas sampler assembly which includes 1) a hood housing assembly to straddle a flowing channel of drilling mud; 2) a sensing head assembly mounted in the hood housing assembly to measure amount of methane gas therein; and 3) a pump assembly operable to draw inlet air through the sensing head assembly and discharge air into the channel of drilling mud. The discharge air acts to agitate the drilling mud to increase release of methane gas therein to transmit a more accurate measurement of the methane gas to the recorder assembly.
