The safety handle of a new production is mixture of gas-warning,electricity testing,supporting,length meaure and so on.

In order to further understand influences of polymer on logging curves and to provide foundation of logging interpretation,influences of polymer on electric petrophysical properties are studied by electric petrophysical experiment aiming at sand reservoir.

A comparative electric petrophysical experimental study by oil displacement method on artificial pure sandstone samples and natural samples with low resistivity concluded that no matter what kind of sample is,one of important factors causing low resistivity pay is the high irreducible water saturation which is determined by the shale content and the complication of pore structure in the rock.

This paper introduced the process of a hydrogen explode at 600 MW generator,analyzed the explode cause from the aspects of hydrogen displacement and electric test,then some suggestions and measures are proposed for gas displacement in generator and electric test.

The paper discusses present methods of electric tests for generators in China, a new multifunctional supervision test system for parameter measurement of generators, electric start-up test and failure records is introduced, and the advantage, practicality and special characteristics of the system are presented.

So the electrical inspection of the hazardous areas is very impor- tant, which is the focus of the platform electrical inspection.
