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.

In order to play a full role of mud logging technology in steering the horizontal wells,increase the drilling rate of coming across the oil bed by the geologic steering,enlarge the exposed area of the reservoir,obtain the aim of increasing the residual oil and oil and gas production amount of single wells and decreasing the exploration and development cost,the research was carried out and the special software was made according to the geologic features in Zhongyuan Oilfield,and the geologic steering chart was drew by using various parameters and data collected during mud logging. By the stratum contrast,the location of the horizontal target zones was accurately predicted and clicked,with the help of the curve features of oil reservoir and non oil reservoir,whether the bit was passing the oil bed or not could be judged,and with the accurately calculated stratigraphic dip,the bit could be made to pass in the oil bed as more as possible. The well site experimental application technology was practicable and adaptable and has become an indispensable technical mean for the horizontal well operation.
