Fast computing methods for dual laterolog response of fracture of rigid sandstone reservoir;

Research and application of coal seam log response predicted from seismic attribute;

Study of acoustic log responses to the overpressure formation in the southeast Qiong basin;

Analysis of cased-hole resistivity logging responses;

Review of Continental Sedimentation Logging Response Characteristics;

Then based on computing the minimum of the difference between actual and reconstructed theoretical logging response to obtain the optimum solutions of the geologic parameters,this paper built up a logging interpretation model for igneous .

In this paper, using the digital and analog recordings of calibration signals, referring to the known amplitude characteristics of analog recording, we calculated and obtained the instrument response for digital recording system of Chengdu Telemetry Seismic Network (CTSN).

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.
