Secondly,from the aspects of technology principles,application status and adaptable conditions,testing technologies for frost layer parameters,such as surface temperature,thickness,density,thermal conductivity and morphology of the frost layer,etc.

The purpose of this investigation is to study the regularities of frost growth and distribution along the fin pipes and the changes of air flow rate and pressure drop through unit cooler.

The regularities of frost growth and distribution along fin pipes and the changes of air flow rate and pressure drop through fin pipes were obtained by computer’s simulating the practical operating conditions of unitcooler.

The lithology of deep wells in eastern Daqing oil field and complex,so calculating reservoir parameters and recognizing fluid are very difficult.

Taking intermittent test production well as studied objective, by arranging former test production data and using initial producing data acquired at intermittent process, formation parameters at two stages of testing and intermittent test production periods for natural potential and reformed wells are compared and analyzed and forecasting method is studied.

In addition, the important forms used to calculate the formation parameters, such as shale volume, water saturation and permeability, are improved to be more suitable for the calculation of inhomogeneous formation parameters according to the power law of fract.

The problem in testing analysis, such as longer closed-in time, multi-answers of interpretation and low-permeable formation parameters which can not be obtained by conventional well testing ways, have been solved through the applica.
