Modify mud pump operation to reduce maintenance. [Method to reduce abrasion in well-drilling mud pumps]
- White Rock Engineering, Inc., Dallas, TX (United States)
The following proposal is based heavily on exponential wear' functions. By simply slowing the main pump down to half rated speed and compensating with the other standby' pump at the same speed, each pump contributes an equal share of required output. This results in remarkable parts life increase, approaching well over twice that of conventional two pump standby' operations (one running and one standby) on typical rig systems. The corresponding reduction in mechanical maintenance is worth noting considering that, presently, the cost of pump parts may reach about $1 million over the life of two drilling rig mud pumps. A single pump operated at reduced speed exhibits enormous parts life increase, but a second pump is needed to make up required output. Even though the number of parts is doubled there is still a relevant economic benefit from increasing parts life.
