CONSTANT HEAD PUMP FOR SONIC WAVE GENERATOR USED IN TREATING SUBSURFACE FORMATIONS |
摘要 |
A sonic wave generating device transmits variable wave energy to a fluid medium that is transmitted to objects such as subsurface petroliforous formations to be treated. A feed pump which pumps the medium to the devices includes means to maintain an increased hydrostatic or positive head to the suction inlet to the feed pump which prevents or neutralizes feed back energy waves from the wave generating device to the feed pump.
