【Abstract】 The sonic wave sending technique of early air cutting detecting is an advanced one.The bottleneck of the method, which is the sonic wave emitter,has been systematically studied.The paper offers 4 techniques to solve the problem.They are the flow rate changing technique by electromotor speeder,the pressure releasing and diffluence technique,the flow increasing technique with double pumps and the flow rate changing technique by diesel engine speeder.Also,the applicable range,the advantages and field using conditions of the 4 techniques are analyzed in the paper.It is indicated that the flow rate changing techniques by electromotor and diesel engine speeders are 2 safe,reliable and expansible techniques.The two techniques have been tested in several wells and the results are satisfactory.更多还原
