Cementing Ground Anchor
Dec 22, 2022| Cementing ground anchor:
The most core part of prestressed cementing technology is the design of ground anchor. The design of prestressed ground anchor directly affects the success or failure of cementing in thermal recovery Wells. Whether the damage of cementing casing can be reduced and the life of cementing casing can be extended depends on the design of prestressed ground fault. Therefore, it is very important to study prestressed cementing ground anchor in thermal recovery well. The core component of ground anchor is the anchor claw part, the force of the anchor claw is relatively complex, so the finite element analysis software is used to carry out static and dynamic analysis of ground anchor, improve the cementing efficiency of the anchor claw, and meet the needs of cementing thermal production Wells. First of all, the design has a strong practical application pertinence, it mainly solves the ground anchor in the soft stratum cementing failure, the casing process encountered resistance can not circulate, the casing in hot mining high thermal stress and other actual problems, improve the success rate of prestressed cementing. Secondly, to a certain extent, it can save the huge economic loss and bad social influence caused by the failure of ground anchor. Moreover, the design has a strong practical applicability and guiding significance for some similar problems in cementing in the future. Finally, the design of the ground anchor can reflect some advantages that are different from the conventional cementing ground anchor in principle, structure and performance.
