Embodiment 1

[0032] refer to Figure 1-8 As shown, a mechanical slip oil pipe anchor includes a central pipe 1, an upper joint 2 and a lower joint 3 sleeved on the outside of the central pipe 1 in sequence, and a slip sheet is sleeved and installed between the upper joint 2 and the lower joint 3 4. A matching retracting mechanism is installed on the outer sleeve of the slip 4, and a clamping mechanism matching the upper joint 2 is installed on the top of the central tube 1 .

[0033] The retracting mechanism includes a transmission box 15 fixed on the front side of the central pipe 1 through a connecting block 21, a pressing ring 5 is sleeved on the top of the slip 4, and a pressing ring 5 is symmetrically installed on the outer wall of the middle of the slip 4. A spacer 26 is arranged against the lower end surface of the ring 5, a rack rod 12 is slidably inserted in the transmission box 15, and the top of the rack rod 12 is sleeved with a limit frame body 11 that is fixed on the outer wal...

Embodiment 2

[0036] On the basis of the first embodiment, two fixed sleeves 8 are fixed symmetrically on the outer wall of the slip 4 with respect to the rack bar 12, and two fixed sleeves 8 are slidably fitted with uprights 7. The tops of the two uprights 7 Both are fixed with the outer wall of the pressing ring 5 through the fixing block 6, the bottom of the two uprights 7 are fixedly installed with anti-detachment cylinders 10, the two uprights 7 are sleeved with springs 9, and the ends of the two springs 9 are fixed. The two ends are respectively set against the fixing sleeves 8 and the anti-separation cylinders 10 at the head and tail ends of the two uprights 7 .

[0037] In this embodiment, the up and down movement of the pressing ring 5 driven by the rack rod 12 is realized by the elastic reset ability of the column 7, the fixed sleeve 8 and the spring 9, and the regularity of the pressing ring 5 during vertical movement is improved. .

Abstract

The invention discloses a mechanical slip oil pipe anchor, which relates to the technical field of oil pipe fixing equipment. There are slips, and the outer sleeve of the slips is equipped with a matching finishing mechanism, and the top of the central tube is equipped with a clamping mechanism matching the upper joint, and the finishing mechanism includes connecting blocks The transmission box body fixed on the front side of the central tube, the top of the slips is covered with a pressing ring, and the outer wall of the middle part of the slips is symmetrically installed with a spacer set against the lower end surface of the pressing ring, A rack bar is slidably inserted in the transmission box, and the top of the rack bar is covered with a limiting frame fixed on the outer wall of the pressing ring. In the present invention, the electric tool rotates the rotating shaft and then drives the gear to realize the upward movement of the pressing ring, realize the strong retraction of the slips, and ensure the easy disassembly of the anchor as much as possible.

Description

technical field [0001] The invention relates to the technical field of oil pipe fixing equipment, in particular to a mechanical slip oil pipe anchor. Background technique [0002] The task of oil production engineering is to make oil and gas flow smoothly into the well through a series of engineering and technical measures that can act on the reservoir, and the well can efficiently lift it to the surface for separation and metering; its goal is to cost-effectively improve oil well and crude oil recovery. From the point of view of systems engineering, oil production engineering is a central and important subsystem in the large oilfield production system, and is closely related to reservoir engineering and oil and gas gathering and transportation engineering in mines. The use of tar and petroleum has been around for thousands of years. Artesian oil, gasoline and tar are available all over the world. The famous Los Angeles La Brea tar pits (La Brea tarpits) is an artesian oi...
