Abstract
A gas trap apparatus for liberating gas from drilling mud and collecting such gas for analysis. A motor is connected to a rotatable vertical shaft having beater bars thereon, which when the shaft is immersed in drilling mud and rotate, stirs such mud to liberate gas entrained therein. The gas trap is characterized in having a top member and a bottom member which surrounds the vertical shaft and which is releasibly secured to the top member thereof by a quick release mechanism which facilitates rapid detachment of the bottom member from the top member to permit quick access said vertical shaft and beater bars thereon for replacement or servicing. The vertical shaft may further likewise be provided with a quick-release means to allow quick release of the shaft from the motor for easy replacement and servicing of same.
Claims (11)
1. A gas trap apparatus for liberating gas from drilling mud, comprising:
an elongate, vertically-downwardly extending shaft, having stirring means thereon to stimulate and cause circulation of drilling mud when extended into and rotated within drilling mud;
motor means for rotating said downwardly-extending shaft, a top member, situated below said motor means, said shaft passing vertically downwardly through and extending below said top member, having a gas collection port therein for allowing gas liberated from said drilling mud to be collected and withdrawn for analysis;
a bottom member, extending around said shaft; and quick-release coupling means, releasibly coupling said upper portion of said bottom member to said lower portion of said top member, to permit rapid detachment of said bottom member from said top member to thereby allow access to said downwardly-extending shaft and stirring means when same need servicing or replacement.
an elongate, vertically-downwardly extending shaft, having stirring means thereon to stimulate and cause circulation of drilling mud when extended into and rotated within drilling mud;
motor means for rotating said downwardly-extending shaft, a top member, situated below said motor means, said shaft passing vertically downwardly through and extending below said top member, having a gas collection port therein for allowing gas liberated from said drilling mud to be collected and withdrawn for analysis;
a bottom member, extending around said shaft; and quick-release coupling means, releasibly coupling said upper portion of said bottom member to said lower portion of said top member, to permit rapid detachment of said bottom member from said top member to thereby allow access to said downwardly-extending shaft and stirring means when same need servicing or replacement.
2. The gas trap apparatus as claimed in claim 1, wherein said quick release coupling means comprises a "U" shaped locking member, which is removably insertable in apertures in each of said top member and said bottom member.
3. The gas trap apparatus as claimed in claim 1, wherein said quick-release coupling means comprises at least one manually-actuated clip which may be easily released to permit detachment of said upper portion of said bottom section from said lower portion of said top section.
4. The gas trap apparatus as claimed in claim 3, wherein said at least one manually-actuated clip comprises :
(i) a plurality of bale members, pivotally secured to said lower portion of said top section about a periphery thereof, and (ii) a plurality of protuberances, extending from said upper portion of said bottom member, engagable with said bale members to releasibly secure said bottom member to said top member.
(i) a plurality of bale members, pivotally secured to said lower portion of said top section about a periphery thereof, and (ii) a plurality of protuberances, extending from said upper portion of said bottom member, engagable with said bale members to releasibly secure said bottom member to said top member.
5. The gas trap apparatus as claimed in claim 3, wherein said at least one manually-actuated clip comprises :
(i) a plurality of bale members, pivotally secured to said lower portion of said top section about a periphery thereof, and (ii) a plurality of protuberances, extending from said upper portion of said bottom member, engagable with said bale members to releasibly secure said bottom member to said top member.
(i) a plurality of bale members, pivotally secured to said lower portion of said top section about a periphery thereof, and (ii) a plurality of protuberances, extending from said upper portion of said bottom member, engagable with said bale members to releasibly secure said bottom member to said top member.
6. The gas trap apparatus as claimed in claim 3, wherein said at least one manually-actuated clip comprises :
(i) a plurality of bale members, pivotally secured to said upper portion of said bottom section about a periphery thereof, and (ii) a plurality of protuberances, extending from said bottom portion of said top member, engagable with said bale members to releasibly secure said bottom member to said top member.
(i) a plurality of bale members, pivotally secured to said upper portion of said bottom section about a periphery thereof, and (ii) a plurality of protuberances, extending from said bottom portion of said top member, engagable with said bale members to releasibly secure said bottom member to said top member.
7. The gas trap apparatus as claimed in claim 1, wherein said quick-release coupling means comprises segmented rim means on each of said lower portion of said top member and said upper portion of said bottom member, to permit locked engagement thereof, wherein said upper portion of said bottom member when inserted into and rotated in a first direction about a vertical axis relative to said top member, becomes secured to said top member due to engagement of said respective segmented rim means, and when said bottom member is rotated in an opposite direction about said vertical axis said bottom member may be removed from engagement with said top member.
8. The gas trap apparatus as claimed in any one of the preceding claims, wherein (i) matingly engageable quick release coupling means is further situated on said downwardly-extending shaft and on said motor means, to allow said shaft to be quickly attached and detached from said motor means.
9. The gas trap apparatus as claimed in any one of claims 1-7, wherein (i) matingly engageable quick release coupling means is situated on said downwardly-extending shaft and on radially-outwardly extending members therefrom, to allow said radially-outwardly extending members to be quickly attached and detached from said shaft.
10. A gas trap apparatus for liberating gas from drilling mud, comprising:
an elongate, vertically-downwardly extending rotatable shaft, having radially outwardly-extending bar members adapted when extended into drilling mud and rotated therein to cause stirring of said drilling mud and liberation of gas therefrom;
motor means for rotating said downwardly-extending shaft, quick-release coupling means situated on said downwardly-extending shaft to allow said shaft to be attached and detached from said motor means;
a top member, situated below said motor means, said shaft passing vertically downwardly through and extending below said top member, having a gas collection port therein for allowing gas liberated from said drilling mud to be collected for analysis;
a bottom member, extending around said shaft, having a mud ingress aperture therein and a mud egress aperture therein, and quick-release coupling means, releasibly coupling said upper portion of said bottom member to said lower portion of said top member, to permit rapid detachment of said bottom member from said top member to thereby allow access to said downwardly-extending shaft and stirring means when same need servicing or replacement.
an elongate, vertically-downwardly extending rotatable shaft, having radially outwardly-extending bar members adapted when extended into drilling mud and rotated therein to cause stirring of said drilling mud and liberation of gas therefrom;
