随着科学技术的发展，岩心钻探用的冲洗介质的种类越来越多，根据目前已知的资料，大致分为三类。
泥浆泵是在钻探过程中，向钻孔输送泥浆或水等冲洗液的机械。
Mud in the drilling process, the drilling mud or water transport machinery such as washing fluid.
泥浆泵原理泥浆泵是在钻探进程中，向钻孔运送泥浆或水等冲洗液的机械。
Mud Pump Principle is in the process of drilling mud to the drilling mud or water transmission fluid mechanics.
泵的压力巨细取决于钻孔的深浅﹐冲洗液所通过的通道的阻力以及所运送冲洗液的性子等。
Pressure of the pump depends on the depth of drilling, the channel through which irrigation fluid resistance and the nature of delivery of irrigation fluid.
