, if, a a, g,) 5 0- 3 ANCHOR for INSTALLING INSTRUMENTS IN THE BLOWER

The utility model relates to the oil and gas industry and can be used in well research technologies with instruments installed in the well.

There are various devices for installing devices in the well: on cable, on pipes, on suspensions (see, for example, certificate RU No. 22503 IPC 7 ЕВВ 47/01, 2001).

The disadvantages of the known devices are the complexity of the installation of devices, the need to keep in the well cables, pipes or suspensions for the entire period of operation of the installed devices.

These disadvantages are eliminated in the known device such as anchors, adopted as a prototype.

An anchor for installing devices in a well according to the prototype includes a housing with holes and channels in which mounting legs are mounted, a mechanism for acting on the legs, an anchor head, a bayonet lock for installing devices and weights (see, for example, E.I. Bukhalenko , V.E. Bukhalenko, Equipment and tools for repairing wells, Moscow: Nedra, 1991, p. 266-270).

The disadvantage of an anchor is the complexity of its construction, leading to unreliable operation.

The objective of the utility model is to eliminate these drawbacks.

The technical result achieved by using the proposed utility model is the simplicity of its design, the minimum number of parts, reliable operation.

IPC 7 E21B 47/01

according to the utility model, levers are mounted on the axis, on one side of which protrusions are made, and on the other, hollows interacting with the cam of the mechanism for acting on the paws, made in the form of a rod, on one end of which there is a head for the catcher, in the middle part there is a cam, and on the other end there is a bayonet lock.

The execution of the mounting legs of the levers placed on the axis, on one side of which protrusions are made, and on the other hand, troughs that interact with the cams of the mechanism for acting on the legs, provides the greatest possible simplicity of design: only two designs of parts - levers and cams acting on ryagi through protrusions and depressions on them.

The implementation of the mechanism for influencing the legs in the form of a rod, on one end of which there is a head for the catcher, and in the middle part - the cam also provides the maximum possible simplicity of the mechanism in the form of just one part, combining the functions of the catcher and the impact on the legs.

Simplicity of design, minimum number of parts ensure reliable operation of the anchor.

The proposed anchor is shown in the drawing, which shows its longitudinal section in the pipe, where the anchor is installed.

The anchor for installing devices in the well contains a housing 1 with holes 2 and 3 and a channel 4 into which mounting feet 5 are mounted, a mechanism for acting on the feet 5, a head 6 for the anchor catcher, a bayonet lock 7 for installing devices and weights. As mounting paws 5, levers 5 are placed on the axis, on one side of which protrusions 8 are made, and on the other hand, depressions interacting with the cam 10 of the mechanism for acting on the paws 5.

The mechanism for acting on the paws 5 is made in the form of a rod 11, on one end of which there is a head 6 for a catcher, in the middle part - a cam 10, and at the second end - a bayonet lock 7.

An anchor works as follows.

At the wellhead, the head 6 for the anchor catcher, located on the rod 11, is inserted into the drive socket. The rod is in the upper position at a stroke distance H, and its cam 10 acts on the protrusions 8, forcing the levers 5 to fit in the channel 4 without protruding parts. Then, instruments and weights are installed on the bayonet lock 7 and the anchor is lowered into the well in the interval of its installation, where the drives release the head 6, and the anchor is released from the drive. Instruments and goods hung on the lock of the bayonet 7, move the rod 11 down, as the housing 1 touches the walls of the pipe and is braked. As a result of the displacement of the rod 11, the cam 10 acts on the hollows 9 of the levers 5 and displays the levers 5 in the working position. The anchor, moving downward, rubs levers 5 on the inner surface of the pipe and as soon as it approaches the coupling gap, levers 5 enter the gap and the movement of the anchor stops. Instruments lit to the anchor carry out the necessary measurements for a given time. After the end of the measurement time, the anchor catcher is lowered into the well, which captures the head 6 and begins to rise the anchor. The rod 11 moves upward by the amount of its stroke H, the cam 10 acts on the protrusions 8 of the levers 5, as a result of which the levers 5 move on an axis into the channel 4 without protruding parts.

An anchor, having a small amount of detail, works simply and reliably.

Claims (1)
