The monitoring and analyzing technique platform while drilling horizontal wells is a technical software which makes fast generalized analyses and drilling guidance to target objects during drilling horizontal wells,which integrates the information of geology,mud logging,drilling,measurement while drilling into a whole body,has the technical superiorities of field generalized analyses,provides a comprehensive technical analysis method for realizing on-site fast tracing objects and carrying on geological analyses precisely in visibility and timeliness,and becomes a field analysis tool for drilling horizontal wells in the complex oil-gas areas.

As the cuttings are fine and rare caused by various new drilling technology which has brought serious influence on wellsite fast and accurate evaluation for oil bearing properties of drilling fluid logging cuttings, Geologging Section in Zhongyuan Oilfield carried out the technical development study on evaluating cutting oil bearing property by using fluorescence digital image. This technology merges the micro fluorescence, optics, image technology and computer technology, it adopts the mixed sample to analyze and collect fluorescence digital image directly, and does not need to choose oil sand sample to process sample in particular, which realizes digitalized collection for information characteristics of cutting oil bearing property, original and permanent storage and application, and also realized automatic, intelligent and quantitative analysis and evaluation. Its key technology of oil bearing cutting fluorescence image characteristics and recognition, has been obtained with significant breakthrough, 3 characteristic key elements were optimized: image color S, sandstone surface occurrence B and image intensity M,and the recognition standard and chart was established. By the statistics and analysis for more than 2000 horizons of 20 wells, the distinguishing coincidence rate of oil bearing cutting has reached to 90% by practice verification. The comparing application results shows that the fluorescence image distinguishing technology has better consistency with the detecting and analyzing results of geochemistry, light hydrocarbon, pyrolysis, and nuclear magnetic resonance and also has good consistency with wireline logging and recovery testing results. The application of the technology not only made up the shortage of conventional geologging, but also improved the application value for geologging information.
