This invention relates to a mud ditch which is used in the drilling of an oil well and provides for the circulation of the mud as .it returns from the well and then flows to a pickup sump where the mud pumps pickup the mud and again 1' urnit into the well.
Heretofore, the mud ditch, as well .as the sumps, have been built of wood. thus requiring the labor of .a. considerable number of men, and the consumption of .a considerable amount of time.
An object of my invention .is 'to provide a novel portable mud ditch formed of a plurality of metal units, the various units fitting together to provide a complete mud circulating system of sumps and ditches.
Another object of my invention is to provide a novel portable mud ditch in which the various units. need not be precisely placed, but on the contrary can be misplaced and misaligned to a considerable extent. and the units will still efiectively fit together and perform their required function of conducting the flow of mud from a well to a sump.
Another object of my invention is to provide a novel portable mud ditch .in which the various units can be quickly and easily coupled in a minimum amount of time.
A feature of my invention resides in the novel means of packing the fitting unit from the trough unit to prevent leakage between the fitting and the trough Another feature of my invention is to provide fitting units which permit angular. positioning of the trough units.
Other objects, advantages: and features of inventi may pp r m th acc mpanyin drawing, the suhjoined detailed description and the appended claims.
In the drawing:
Figure 1 is a. fragmentary top plan view of my portable mud ditch.
Figure 2' is a sectional view taken on line 2--2 of Figure 1.
Figure '3 is afragmentary plan view as viewed from the line 3-3 of Fi ure 2'.
Figure 4 is. a diagrammatic fragmentary plan of the T-fitting and the mud troughs.
Figure 5 is a fragmentary plan view similar to Figure 4 .and showing a different position of the T-fitting and mud troughs.
Figure 6 is a view similar to Figure 5 and showing still another position of the T-fitting and mud trou hs. s .Ilgurc '1- is a. iragmentaxyblan view in molar positioning of the mudtroughs.
Figure 8 is a fragmentary perspective view of the 'T-fitting and one of the mud troughs.
Referring more particularly to the drawing, the numeral 1 indicates a-collecting sump into which the mud spills as it comes from the well and then flows into the trough unit '2, and thence into the fitting element 3, then into a, second trough element 4, and finally into the sump 5, from which the mud pumps pick up the mud and return it to thewell which is being drilled.
As thus far described, the arrangement of parts is usual and well known in the art, and the position and operation of the mud pump, for example, forms no part of my invention.
Heretofore, the sumps "I and 5, as well as the trough elements 2 and 4, have been constructed of wood and this required a separate structure to be erected on each new well, and then subsequently destroyed or moved when the well was completed. In my construction, the sumps l and 5, as well as the troughs 2 and 4, and the fitting element 3 are all constructed of metal. It will be evident that the sumps I and 5 cannot readily be positioned accurately around an oil well to within a fraction of an inch, nor is it feasible to have to position the fitting element 3 accurately with relation to the sumps I and 5. To permit a considerable amount of variance in alignment of the parts 'I, 3 and 5, I provide a means of coupling the troughs 2 and 4 to the elements 1, 3 and 5, so that there can be a. considerable misalignment both horizontal and vertical and also a variance in spacing, and the various elements can still be efiectively connected with the troughs so that the mud will flow from the collection sump l to the sump 5 in a continuous stream, and without loss of the mud in transit.
Considering first the trough 2, this is made of metal, is substantially U -shaped and open at the top as shown in Figure '2. The bottom is fiat as shown at 6, and the sides '1 are substantially at right angles to the floor 6 and also the floor and sides are connected by a curved fillet B. The
purpose of this construction is to enable the pack ing arrangement, which will be subsequently described. to more effectively engage and seal off this trou h to prevent leakage around the trough as the mud flows from the sump l to the sump 5. The trough 2 extends from the sump l to a fitting generally indicated as 3, and this fitting is preferably T-shaped so that the trough 4 can extend substantially at right angles to the trough 2. The fitting 3 rests on a metal frame or foundation .9, which in urn rests on the ground. The frame 9 may vary-both as to distance from and alignment with the sumps I and 5, and to permit of this variance, I provide the fitting 3 with two or more outlets [0, into which the troughs 2 and 4 can extend substantially as shown. The side walls H and I2 and the bottom which extend from the openings I fiare outwardly at an angle from the openings so that the troughs 2 and 4 can enter the fitting 3 at various angles substantially as shown in Figures 4, and 6. This permissive misalignment of the parts 2, 3 and 4 is of considerable importance in that the workmen need not spot the sumps and the fitting element accurately and the parts will still fit, and the troughs 2 and 4 will fit into their respective elements without having to realign the parts or to bend the troughs or to create a leak at the joints between the fitting 3 and the respective troughs.
A channel I3 is welded or otherwise fixedly secured to the fitting element 3 at each of the opening; it, and a packing l4 fits in this channel, the packing being preferably circular in cross section. The packing [4 projects beyond the inner edge of channel l3 so as to yieldably engage the side walls I and bottom walls 6 of the troughs 2 or 4. Due to the fact that the side wall 1 and bottom 6 are substantially straight lines, the packing M can more effectively engage and pack off against these surfaces, thus eliminating any leakage around the trough. There is not a great deal of pressure on the drilling mud which fiows through the troughs and, consequently, the seal need not be very precise nor operable under high pressures. To hold the troughs 2 and 4 in position, I provide J-bolts I5 which extend from the top flange [6 of the fitting 3 and engage the upper surface of the trough substantially as shown in Figure 8.
If it is necessary to arrange the trough 2 or 4 at an angle, I may provide fittings ll as shown in Figure '7. These fittings may be arranged at any fixed acute angle and they include a troughlike structure with side walls 18 and with packings 2d and 2|, and each end to engage the troughs 22-43 as shown. The method .of packing off around the trough 22 and 23 is the same v as described to pack off the trough 2 or 4. 7
Similarly, if the troughs must be elongated, I provide a fitting 24 as shown in Fig. '7 which is open at both ends, and is provided with packings 25-2fi at each end respectively, thus accompanying a second trough 2'! in alignment with the trough 23. The mud, as it moves from the trough 4 is diverted through one or more outlets 28 into the sump 5, where the mud pumps again pick it up to recirculate the same. A fitting 29 similar to the fitting 24 is mounted on the sump i, and similarly a fitting 30 accommodates the end of the trough 4 so that the mud is directed into the final distributing trough 3|.
