Application Of Integrated Directional-mud Logging-geosteering Technology In Huangling Block In Ordos Basin

With the deepening of Ordos Basin exploration,the exploration goal has been shifted from thick layer and high hole permeability to thin layer,low porosity and low permeability compact oil and gas layery,at present in view of these complex reservoir with the method of horizontal well exploration,It is demanding and difficult for horizontal well drilling of well trajectory require high precision control,to carry out the fixedg uide integration technology research,to guide drilling horizontal well become a press-ing problem in the study of geological drilling horizontal Wells.Papers to ordos huangling block Yan Chang group 6 section of the reservoir is low porosity low permeability reservoir as the research targer,conducted on record the guide integration technology research,the paper combined technology research and engineering practice,in a small layer of fine classification and correlation,based on the analysis of the structure description and reservoir characteristics,use 3D visuali-zation of remote tracking geosteering analysis system to establish three-dimensional geosteering model;Carried out on its derivative according to the acquisition and proce-ssing method study,through the data real-time transmission and analysis,the well traj-ectory real-time tracking,and compared with geological model and logging while drilling drilling trajectory fine-tuning,realize the purpose layer drill encounter rate 94.7%,increase the control accuracy of horizontal well drilling,realized the high pre-cision of target,effectively improve the reservoir drilling rate,on the set in the region for the first time a record the integration technology of geosteering drilling horizontal well,provides the definite record guide integration technology and its application me-thods and practical examples.
