- Abstract:
- This paper introduces the technical status of rock permeability measuring technique to gas flow quantity measurement at home and abroad. Aiming to the problems of rock gas permeability measurement in the exploration and development process of oil/gas reservoir of low permeability, a set of automatic measuring device of throttling capillary gas flow quantity was developed, the throttling capillary P(Pressure)-Q(Quantity) regression measuring approach of rock permeability was set up. The approach, which is fast to measuring speed of the gas passing through rock, high to measuring accuracy, and high to automatizing degree, is a great breakthrough to measuring technique of rock gas permeability. The throttling capillary gas flow measuring device introduced in the paper granted the patent of invention in China, the patent No.is ZL-01278258.0.
