Practical effect of SLXL-2 small size mud logging unit used in development wells.;

Application of positive pressurized safety control technology in SDL9000(CHINA) mud logging unit;

With the development of computer and its network technology,the graphic terminal devices can't meet the requirement of wellsite informationization,which were produced in 1990's for quite a part of mud logging units and are still used now.

In order to meet the needs of simply mud logging,es- pecially to fit the demand of mud logging of low cost for the development well,Geologging Company of Shengli Oilfield developed a new type of mud logging unit.

TDC synthetic well logging instrument can measure the volume change of mud in several mud pits at the same time.

The methed and cireuit principle of pump rate and rowt speed measurement are same in comprehensive mud logginginstrument, some important papamters such as entrance flow rate in and lag time can be obtained by the measurement ofpump rate, it is important to measure the rotary for the safe and rapid drilling.

Positive pressure explosion-proof technique of SDL9000 comprehensive logging instrument;

Trouble shooting method for SDL-9000 comprehensive logging instrument;

Based on the application principle of comprehensive logging instrument in the field engineering supervision,combining with the analysis and summary of monitoring actual example,the function and contribution of comprehensive logging instrument and its technique in oil-gas exploration and development are described.

Improvement in voltage interface circuit of the mud logging unit.;

Application of domestic fast chromatographic instrument in the reform of the imported mud logging unit chromatographic system.;

At present,due to the problems of product criteria being less developed,assortment and specification being too many in mud log- ging unit normalization,they make domestic mud logging unit tech- nical feature in inconsistency and non-normalization,thus hampe- ring operation,maintenance and data application and increasing e- quipment operating cost.
