An improved line injection method is presented in which the transfer impedance of the shielded multicore cable is measured first from which the shielding effectiveness is.

In the paper , the definition of he shielding effectiveness is first introduced Then according to the difference and relationship between the coaxial cable and multi-core cable,an improved line injection method is presented which can be used in measurement of the shielding effectiveness of multi-core cable.

4 oilfield and an investigation on literatures in China and abroad, the ECLIPSE100 software,a black oil model simulator,is used to make numerical simulation for several immiscible gas injection schemes.

This paper studies the factors including injection pattern, injection procedure and slug size which influence the displacement efficiency of loam flooding.

First, we had done the research on the injection pattern and measurement of viscoelasticity of the ternary compound systems with each kind of polymer, respectively, from which concluded that resistance factor and residual resistance factor increased as the increasing of the concentration of polymer, and so the viscoelasticity did.

The authors research the buried time, figures, the source of oil and gas, the migration of oil and gas and the direction of injection by using homogenization temperature and oil and gas components of fluid inclusion.
