Abstract

The bonnet is subject to hefty erosion due to the redirecting of the mud stream to the inner bore. Thus, erosion is one of the main reason to decommission the bonnet. I propose placing an insert at the position inside the bonnet where the redirection of the mud stream takes places. Depending on the chosen inlet material, the erosion can either be avoided or mitigated. The inlet can be replaced if needed. Therefore, the bonnet will last much longer.

Title: Insert for Mud Motor Bonnet Abstract: The bonnet is subject to hefty erosion due to the redirecting of the mud stream to the inner bore. Thus, erosion is one of the main reason to decommission the bonnet. I propose placing an insert at the position inside the bonnet where the redirection of the mud stream takes places. Depending on the chosen inlet material, the erosion can either be avoided or mitigated. The inlet can be replaced if needed. Therefore, the bonnet will last much longer. Description: I am proposing an insert that will be installed into the bonnet at the position where the flow redirection into the inner central bore takes places. This will mitigate the hefty erosion onto a cheaper part that can be exchanged eventually. The Inlet shall include ports in order to make the flow redirection more smooth. Additionally, the insert can be made of highly erosion resistant material (such as tungsten carbide) to further reduce the effects of erosion. The insert can be made conventionally (turning, milling) or can be created with additive manufacturing. It is mandatory that there is easy access to the insert in order to change it. Currently, the bonnet is not protected regarding erosion. Any damage leads to exchange of the bonnet, a big and expensive part. The novelty is that a protective sleeve (referred is insert) is now mitigating all inner erosion from the bonnet. The insert I describe includes bores, a mean that allows the inlet to cover all crucial area that i...
