Description

Drilling fluid conveying pipeline device

Technical field: a kind of drilling fluid conveying pipeline device, the drilling fluid that is used for the drilling well of petroleum gas cluster well is carried, and relates to a kind of design and manufacturing technology field of drilling-fluid circulation system corollary apparatus.

Background technology: in the relatively more concentrated ocean of petroleum distribution, oil field, land block, carry out the cluster well drillng operation, well quantity is many, well spacing is little, and rig adopts multi-faceted integral translation technology, can satisfy the needs an intensive drilling well of FX, and be provided in solid controlling system on the rig, because equipment is more, quality is big, and manifold connects complicated, so it is also bigger to take the well site area, adopts hydraulic pressure or drag translation schemes such as dress just very difficult; The just present solid controlling system that is equipped with, because each root manifold all is independent connection, and be fixed on different positions separately, so otherwise mobile solid controlling system is realized translation, to guarantee that also it is impossible that drilling fluid is transported to each well location, as the solid controlling system of the present ZJ50 rig that generally uses, do not dismantle the well location translation that whole manifolds can only realize that at most the 20m scope is interior; The resettlement of therefore existing solid control equipment needs the whole solid controlling system of dismounting earlier, move one one of the manifold of different tube diameters to new position then, and then one couples together, so just need to increase cost, increase and remove between ampere-hour, and then prolong drilling period.

Summary of the invention: the purpose of this utility model is at prior art problems, adopts identical caliber to concentrate the remittance dress, distinguishes ways of connecting, designs a kind of drilling fluid conveying pipeline device of modular skid.

The utility model is achieved in that this device comprises sled frame, fixed structure, interior pipe and outer tube, outer tube is fixed on the sled frame by fixed structure, limiting plate on the fixed structure comprises two groups of cross spacing plate and longitudinal spacing plates, be provided with union snap joint at the two ends of outer tube, one end of interior pipe is arranged in the outer tube, the other end is provided with an operating grip, an end that is provided with operating grip is exposed at the outside of outer tube, interior pipe can spur in outer tube freely, constitutes each suit unit with this; When using, according to position, well site and circulating system requirement, path according to the circulating system, each suit unit is placed in segmentation, the interior pipe of pulling out each suit unit then inserts the outer tube of next suit unit successively, each interface is coupled to one with the union ready-packaged joint, forms whole manifold device.

The beneficial effects of the utility model are: adopt independent sleeve structure, transportation module and placement space have been reduced, the segmentation of employing combined type is fixed and is connect, each group suit unit is fixed on manifold with the pipe clamp bearing and drags on the sled, is serially connected then, makes the manifold marshalling, during resettlement, can behind the quick union of dismounting, adopt the fixing mode of closed assembly, be convenient to the modularization transportation.
