Abstract
water-jet deep-rating technology is the use of high-pressure fluid rating the
radial wells for holes. Because of its distinctive characteristics and good prospects in the
transformation of recent wells, It has extensive future in experimentation and testing field in
domestic oil industry. Online system dynamic performance testing of water-jet
deep-rating can effectively reflect the working condition and performance of water-jet
deep-rating machine. It will promote capabilities of domestic independent researching of
water-jet deep-rating technology.
In the treatise, the research of online detection system of water-jet deep-rating
technology was implemented in details by the method of detection and saving of underground
displacement. Through conceptual design methodology, overall programmer of water-jet
deep-ration online testing was studied. In order to meet testing environment and
assembly space needs, the Hall sensor testing programmer was decided finally, and the
solutions for high-temperature which made tremendous impact on online testing was studied
too. Through researching on Hall sensor detection technology, comparing and analysising of
two Hall displacement sensor testing programmer, a improved ism cir
