Description

Elevated trough whole towing device

technical field

The utility model belongs to the field of oil field drilling equipment, and mainly relates to a connecting device suitable for use when a drilling rig drags a well.

Background technique

When the drilling rig is dragging the well, the well position of the dragging well is increased, and the diversion pipe is lengthened, so the hose can only be connected to both ends, and the length of the hose connected to both ends is extended, which will cause grit. This method has a low safety factor and is inconsistent with the standardized construction of the well site.

Utility model content

In order to overcome the above-mentioned defects, the utility model provides an elevated trough dragging device.

The utility model comprises a 90° elbow, a 90° right-angle tee, and a straight pipe assembly. The 90° elbow is connected to one end of the straight pipe assembly through a flange, and a port of the 90° right-angle tee is passed through a method. The blue is connected to the other end of the straight pipe assembly, and at least three liftable supports are arranged below the connected 90° elbow, straight pipe assembly, and 90° right-angle tee, and the three liftable supports are from The direction from the 90° elbow to the 90° right-angle tee is lowered in turn to form an inclined state.

The utility model connects a displacement compensator at a free end of the 90° right-angle tee, and connects another group of 90° elbows, straight pipe components, and 90° right-angle tees through the displacement compensator; Connect in series to realize multiple wellhead dragging wells.

The straight pipe assembly described in the utility model is composed of multiple sections of straight pipes, which are connected by flanges between the multiple sections of the straight pipes, and a flushing interface is set at one end of each of the straight pipes close to the 90° elbow; In some cases, the standpipe gate group can be connected to the flushing interface for high-pressure cleaning.

The remaining port of the 90° right-angle tee in the utility model is connected to the corresponding drilling fluid distributor of the solids control system.

The 90° elbow, 90° right-angle tee, and straight pipe components of the utility model are a group of well mopping devices, one set is used for one well, and a set of mopping well devices is required for adding a well, and two sets of well mopping devices are used. Displacement compensators are arranged between them; the diversion pipe is connected to the 90° elbow, and the 90° right-angle tee is also connected to the diversion pipe. Connecting the diversion pipe, passing through the dragging device, there will be no sand settling phenomenon, and it will not affect the flow rate of drilling fluid. It is suitable for the dragging requirements of various types of drilling rigs; this device meets the requirements of dragging wells, and is quick to install, firm and reliable.

detailed description

As shown in Figures 1 and 2, this elevated trough dragging device includes 90° elbow 1, 90° right-angle tee 2, straight pipe assembly 3, and 90° elbow 1 is connected to one end of straight pipe assembly 3 through a flange , one port of the 90° right-angle tee 2 is connected to the other end of the straight pipe assembly 3 through a flange, and at least three can be installed below the connected 90° elbow 1, straight pipe assembly 3, and 90° right-angle tee 2 Lifting support 4, three liftable supports 4 are lowered successively from the direction of 90° elbow 1 to 90° right angle tee 2, forming an inclined state. The straight pipe assembly 3 is composed of multiple straight pipes 5 connected by flanges, and a flushing port 6 is provided at one end of each straight pipe 5 close to the 90° elbow 1 .

When connecting the mopping device of another well in series, a displacement compensator 7 is connected to a free end of the 90° right-angle tee 2, and another group of 90° elbows, straight pipe components, 90° Right angle tee.

On each well, the remaining port of each 90° right-angle tee 2 is connected to the corresponding drilling fluid distributor 8 of the solids control system.
