Description

DEVICE FOR DELIVERY OF DEVICES TO A HORIZONTAL WELL

The utility model relates to the oil and gas industry and can be used to address the delivery of instruments installed on a geophysical cable into a horizontal well.

A device is known for delivering devices to a horizontal well, which is a column of pipes inside which or at the end of which devices are installed (RF, utility model certificate No. 22503, IPC 7E21B 47 / 01,2001).

The disadvantages of the known device are the large expenditures of time and money for delivering devices to a horizontal well, for ensuring uniform movement of devices in the pipe string, for the need to keep the pipe string in the well for the entire measurement period, which ranges from several hours to several days.

These disadvantages are partially eliminated in another known device for delivering devices to a horizontal well, adopted as a prototype.

A device for delivering devices to a horizontal well according to the prototype comprises a housing, a power drive, a transmission mechanism, a mechanism for moving the device, an instrument head (RF Patent No. 2186194, IPC 7E21B 19/00, 33 / 03,2000).

The disadvantages of the prototype is that the device for delivery is complex and expensive and provides delivery only to cased wells.

The objective of the utility model is to create a device for delivering devices to a horizontal well, devoid of the disadvantages of the prototype.

The technical result achieved by using the utility model is the simplicity of the design of the device and the ability to deliver devices to both cased and uncased horizontal wells.

The specified technical result is achieved by the fact that in the device for delivering devices to a horizontal well containing a housing, a power drive, a transmission mechanism, a mechanism for moving the device, an instrument head, according to a utility model, a rod connected to a pusher is installed as a transmission mechanism as a mechanism the device is mounted with curved rods mounted on the pusher, a power drive with a possibility of automatic reciprocating joint movement Ia rod, push rod and the bent rods with the estimated frequency at the end of the rods mounted legs when needed.

Installing the stem as a transmission mechanism simplifies this mechanism to the highest possible level.

The connection of the rod with the pusher makes it most simple to place the movement mechanism on the pusher, which also simplifies the design of the device.

The installation of curved rods mounted on the pusher as a mechanism for moving the device also simplifies this mechanism as much as possible, and on the other hand, makes it possible to operate the device in both cased and uncased wells, since the rods are equally repelled from the walls and cased, and open hole. To improve the operation of the device in cased and uncased wells, if necessary, paws are installed on the end of the rods.

The implementation of the power drive with the possibility of automatic reciprocating joint movement of the pipe, pusher and curved rods with the calculated frequency provides periodic repulsion of the rods from the walls of the pipe or well and periodic movement of the device with the frequency of the reciprocating joint movement of the rod, pusher and rods. Moreover, for the reciprocating movement of the rod, pusher and rods, neither additional mechanisms nor additional transformations of movement are required, which also simplifies the design of the device.

The proposed device is shown in the drawing, where Fig. 1 is a side view of a device with a partial longitudinal section below the power drive, and Fig. 2 is a sectional view of a leg mounted on a rod.

The device comprises a housing 1, a power drive 2, a transmission mechanism 3, a movement mechanism 4, an instrument head 5. As a transmission mechanism 3, a rod 3 is mounted connected to a pusher 6, curved rods 4 mounted on a pusher 6 are installed as a movement mechanism 4 of the device , the power drive 2 is configured to automatically reciprocate joint movement of the rod 3, the pusher 6 and the curved rods 4 with the calculated frequency. If necessary, paws 7 are mounted on the torpedo rods 4.

The device operates as follows. On the surface, attach the device to the geophysical cable with head 5. Lower the device to the entrance to the horizontal section of the well. They include a drive 2, which is intermittent; jointly and reciprocating, the rod 3, the pusher 6, the bent rods 4 with the calculated frequency. Curved rods 4 or their legs 7 are repelled from the walls of the pipe or well and mix the device for a certain distance in each cycle. After moving the device, the curved rods 4 are returned with the pusher 6 to its original position, and the device remains in a new place. In the next exit cycle of the rods 4, they again move the device a predetermined distance forward. Such movements of the device occur until they reach a predetermined point, after which the drive 2 is turned off and the cable with the device is removed at a given speed to the surface.

Such actions are performed in each well.
