The hydraulic fracturing personalized design , in addition to the need to produce systems with static and dynamic data wells formation rock mechanical parameters of the elastic modulus and Poisson's ratio is crucial . These two parameters , the use of indoor intends triaxial test , ultrasonic rock parameters was determined by measuring the rock specimen aspect slowness calculated longitudinal , transverse wave wave velocity , and combined with mathematical models and on-site construction curve fitting empirical formula recursive method to determine the elastic modulus and Poisson's ratio of rock wells , and to achieve good accuracy . Made of rock parameters , to optimize the design of research , and the implementation of 10 wells in the field . Efficiency increased by 6.7 percentage points with 10 wells not implemented to optimize contrast , the average single well increasing oil more than 1.2t , better optimize the effectiveness of measures
