We need a logging system which can join a variety of downhole tools together to do such jobs as completion well, cement bond and perforation coring based on geological characters in Nanxiang basin.

The tractor for horizontal well logging is a kind of tool to convey the downhole tools in the horizontal well logging.

We develop a zonal pressure measuring technique in two reservoir commingled producing well aiming to solve the problem that we could not measure that before,and integrally design downhole instruments and tools combining the specific lifting mandrel in two reservoir commingled producing well.

Application of instrument amplifier to petrolem logging tools.;

Design calculation of the downhole micromotor-drived logging tool.;

Development of acoustic logging tool and study on its calibration pit;

A novel design proposal for microresistivity imaging logging instrument;

Design of the general maintenance system for well logging instruments;

There are kinds of logging instruments with di ff erent principles,calibrations and measuring methods which are being continuousl y improved, so, the surface logging system should be easily implanted with all k inds of downhole instruments without modifying their software.
