Influence of electro-optic effect on wave-guide efficiency of optical fiber;

Based on the fiber optical grating sensing principle and the sensing model of axial stress function on fiber optical grating,two factors which caused the Fiber Bragg Grating axial sensitivity shift are analyzed-elastic foundation effect and wave-guide effect caused by the fiber diameter change,and the changing curves were drew.

Gas transporting efficiency analysis of gas reservoirs;

Base on the effectiveness of natural gas migration and accumulation process,evaluation standard on transporting efficiency of fault transportation system is established and applied to evaluate transporting efficiency of fault transportation system in the north belt of Kuche depression.

To evaluate crude oil transporting efficiency through fault at the fold-thrust belt in sou-thern margin of Junggar Basin,an evaluating method on crude oil transporting efficiency through fault is established by defining fault transporting coefficient and analyzing effectiveness of crude oil accumulating process.

The electrical efficiency of rocks and its relationship with water saturation;

The text analyzed how about the m index number change with pore structure based on the rock electrical efficiency theory.

Based on the electrical efficiency model for clean rocks and the double water model and parallel conductance between laminated shale and dispersed shaly sand, improved electrical efficiency resistivity model is proposed for laminated and dispersed sand shaly interpretation.
