As a kind of perfect and advanced drilling technique, foam drilling method is accepted by drilling industry in many other coutries, but the high press air-compressor, which has disadvantages of high technical requirement, price and operating cost, extremely limits use and generalization of foam drilling technique; The foam pump booster resolved these problems, which has some advantages of low price, simple structure, handling ease and convenient using, to obtaining optimum structure, we built the experiment equipment for pressure device, and research the increasing capability and the cubage flow rate of it.
