Anti-theft Earth Anchor Development And Application

Anti-theft earth anchor development and application:

In view of the problem that live ground anchors are often stolen, an anti-theft ground anchor is developed. The key technology of the anchor is the anti-theft spiral port. When the anchor is drilled, the anti-theft screw port on the inner pipe of the anchor goes down and gets stuck on the fixing pin. Through the anti-theft screw port and the fixing pin, the torque on the inner pipe is transferred to the main body of the anchor, which drives the anchor to spiral into the stratum. When the anchor is reversed, the anti-theft screw port cannot hang the fixed pin, and the torque on the inner tube of the ground fault cannot be transmitted to the main body of the anchor, so as to realize the anti-theft effect. In normal use, the tension borne by the anchor liner is connected with the main body of the anchor through the annular connecting plate, connecting rod, connecting ring and fixing pin on the inner pipe to transfer the tension. Field application shows that the use of anti-theft ground anchor completely solves the problem of live anchor theft, improves operational efficiency and reduces operational costs.

After more than 20 years of development in Henan oilfield, the dead anchor rope on oil Wells and Wells has been seriously corroded, which cannot meet the needs of safe production. If the dead anchor is re-buried, it will not only take a long time but also cost a lot. The operation of oil and water Wells is more and more frequent, so it is impossible to wait for buried ground anchors, so the method of laying live ground anchors is commonly used to fix ground anchors. This method can solve the urgent need of production, and can be reused, but the live anchor is often stolen after the team moves away, the next operation needs to be replayed live anchor, not only affects the working period, but also causes a lot of waste. For the operation of oil and water Wells in Henan oilfield, 8 000 live anchors are needed every yearEach anchor costs $400, and this alone costs $3.2 million a year. In view of this, the underground operation company of Henan Petroleum Exploration Bureau developed the anti-theft ground anchor, which completely solved the problem of live earth anchor theft, improved the operating efficiency and reduced the operating cost.
