Description
Technical field
The utility model relates to a kind of mud recirculation device, relates in particular to marine module drilling rig mud recirculation device.
Background technology
Traditional horn mouth adopts the mode of straight length and the combination of canalis spinalis section, straight length adopts flange to be connected with the canalis spinalis section, recycle a detachable movable vertical tube and connect horn mouth and preventer, in order to adapt to because height change between the caused preventer of variation of casing head height and the rotating disk.Change in the well head process at drillng operation, owing to need to promote preventer, lower major diameter sleeve pipe, often need the flange between dismounting horn mouth straight length and the canalis spinalis section, and need operating personnel's work high above the ground, whole process is loaded down with trivial details, workload is large, and the activity duration is long, operation inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of easy to use, has avoided work high above the ground, reduced task difficulty, reduce operator's labour intensity, saved the activity duration, improved the marine module drilling rig mud recirculation device of drillng operation timeliness.
Marine module drilling rig mud recirculation device of the present utility model, it comprises the mud backflash and from top to bottom successively by the major diameter pipeline section, the cone section, the vertical tube that the minor diameter pipeline section forms, at described mud backflash mud return duct and mud metering benefit slurry pipeline are installed, described major diameter pipeline section passes mud backflash bottom and is inserted in the described mud backflash and arranges, be provided with the upper sealing pneumatic tyre union for sealing between described major diameter pipeline section and the mud return slot, be provided with the lower seal pneumatic tyre union for sealing between described minor diameter pipeline section bottom and the preventer, be provided with hole for hoist at the major diameter pipeline section.
Advantage of the present utility model:
(1) the mud recirculation device mainly is comprised of mud backflash and vertical tube, vertical tube adopts three sections connections, be respectively major diameter pipeline section, cone section, minor diameter pipeline section, major diameter pipeline section and mud backflash seal by upper sealing pneumatic tyre union, and mud return duct and mud metering are mended the slurry pipeline and be directly installed on the mud backflash.Vertical tube and preventer adopt the sealing of lower seal pneumatic tyre union.The mud backflash relies on existing structural beams and makes, and has solved traditional horn mouth and has hung fixing problem.
(2) adopt the mud recirculation device, replaced traditional horn mouth, and link position and the connected mode of the vertical tube that traditional horn mouth is connected with preventer have been changed, changed the mode that horn mouth straight length and cone section are connected, and cancelled the hinged large dimension lines flange on the horn mouth, make vertical tube capable of expansion and contraction, the vertical tube height is easy to regulate, the while convenient disassembly, all need to dismantle the flange on the horn mouth when avoiding every subjob, avoided the risk of operator's work high above the ground, easy and simple to handle, save time, greatly improved the drilling well timeliness.Also solved the difficult problem of for a long time horn mouth installation difficulty.Also solved simultaneously the Oil Field operating difficulties a difficult problem.
Description of drawings
Fig. 1 is the structural representation of marine module drilling rig mud recirculation device of the present utility model;
Fig. 2 is the enlarged diagram at device I place shown in Figure 1;
Fig. 3 is the enlarged diagram at device II place shown in Figure 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Marine module drilling rig mud recirculation device of the present utility model as shown in drawings, it comprises mud backflash 5 and from top to bottom successively by major diameter pipeline section 1, cone section 2, the vertical tube that minor diameter pipeline section 3 forms, at described mud backflash mud return duct 9 and mud metering benefit slurry pipeline interface 6 are installed, the mud metering is mended the slurry pipeline and can be linked to each other with the mud backflash by the mud metering benefit slurry interface 6 that is installed on the mud backflash, described major diameter pipeline section passes mud backflash bottom and is inserted in the described mud backflash 5, be provided with the upper sealing pneumatic tyre union 4 for sealing between described major diameter pipeline section and the mud return slot, be provided with the lower seal pneumatic tyre union 7 for sealing between described minor diameter pipeline section bottom and the preventer.In use preventer can link to each other by vertical tube adpting flange 8 with minor diameter pipeline section bottom.Be provided with hole for hoist at major diameter pipeline section 1.
The using method of this device is as follows:
1, during drilling well, mud enters the shaft bottom by drilling rod, returns the mud cutting carring and turns back to the mud conditioning device from the annular space between drilling rod and the borehole wall.Return the at first preventer through being connected with minor diameter pipeline section 3 of mud, enter into minor diameter pipeline section 3 again, the cone section 2 of flowing through successively, major diameter pipeline section 1 enter into mud return slot 5.Mud flows to the mud conditioning device by mud return duct 9 again and processes.
2, for the ease of mud metering during pulling out of hole, be provided with the mud metering at the mud return slot and mend the slurry interface, mud is mended the slurry pipeline by the mud metering and is entered mud return slot 5, major diameter pipeline section 1 is advanced in the mud overflow after arriving certain liquid level, flow through successively and bore section 2, minor diameter pipeline section 3, enter at last in the well, reduce the slurry amount of mending of calculating according to the measuring tank mud level.During lower brill, shaft bottom mud can return out in the mud return slot, flows in the measuring tank by the mud recurrent canal and measures.
Major diameter pipeline section 1 and minor diameter pipeline section 3 are respectively by upper, lower seal pneumatic tyre union 4 with are connected and mud backflash 5 and flange 8 sealing that is connected with vertical tube, when operation, in pneumatic tyre, inflate, by gas with the clearance seal between major diameter pipeline section 1 and minor diameter pipeline section 3 and mud backflash 5 and the vertical tube flange 8, when the relative position between needs adjustment VERTICAL TUBE and the preventer, gas in the pneumatic tyre union is emitted, depressurization, vertical tube can always move up and down at the mud backflash, in order to adapt to because height change between the caused preventer of variation of casing head height and the rotating disk.Behind good vertical tube to be adjusted and the preventer relative position, to the pneumatic tyre inflation, realize sealing again.
At major diameter pipeline section 1 two holes for hoist are set, when needs are extracted vertical tube out from the mud backflash, suspension hook are hung on the hole for hoist of major diameter pipeline section 1, vertical tube is extracted out from the mud backflash.
