Description

FIELD OF THE INVENTION

The present invention relates to well equipment, and in particular to a drilling mud collection apparatus for containing a drill pipe connection so as to collect and drain drilling fluid, mud or the like draining from a length of tubing as it is removed from the connection at the well, in a device commonly known as a mud bucket. Unlike devices of the past, the mud bucket of the present invention is comparatively light weight and fluid actuated, so as to provide an easier, more effective, and safer system to operate.

GENERAL DISCUSSION OF THE INVENTION

The preferred embodiment of the present invention comprises an elongated collection tank, preferably cylindrical and split along its length, the tank having an inner diameter formed to selectively envelope the connected joints or connectors of two lengths of pipe (formed of the end pipe and the next pipe on the string) such that, when the pipe is unscrewed from the next pipe, the fluid in the end pipe is collected by the collection tank, which has a drain to direct, via flexible pipe or the like, the collected fluid to a storage tank or the like.

The collection tank of the mud bucket is longitudinally split into first and second parts, which are pivotally connected at one side so as to be able to be opened and closed similar to a clamshell, the system further incorporating one or more actuators to facilitate operation (opening or closing) on demand. The first and second ends of the tank have first and second end openings, respectively, formed to receive and engage the outer diameter of opposing ends of the connected pipe joints of the drill pipes, with said first and second openings having a seal to provide fluid tight, sealed engagement of said outer diameter of the pipes so as to prevent leakage during the draining operation and with the closed tank forming a fluid tight enclosure about the connected pipe joints. The edges of the two split parts forming the collection tank each have gaskets to engage to form a fluid tight container when closed and enveloping the drill pipe during operation.

A support frame to control operation of the tank is provided having a length engaging the first and second parts forming the collection tank, the frame having three pneumatic actuators laterally communicating with the pivotal connection of the split parts forming the tank so as to simultaneously extend on demand to force the pivoted portion of the split tank in a first direction, opening the tank, and a second, retracted position, pulling the pivoted portion in a second direction, closing the tank. Pinch rollers are also used in the closing operation so as to provide pressure against the opposing outer split tank walls to urge the split portions together and align the seals along the split edges of the tank to provide an enclosure having a fluid tight seal where the split edges forming the tank meet. The support frame further supports the first and second parts of the tank in pivotal and slotted fashion, retaining the device in controlled fashion during operation, while allowing the tank component parts to pivot from open or closed position when the actuators extend or retract on demand, respectively.
