Brief review of wellbore exploration engineering technologies over past three years and analysis of engineering requirements for future key exploration sectors in Huabei Oilfield

In past years,on the basis of further study on lithologic hydrocarbon reservoir,Huabei Oilfield shifted focus on such new exploration fields as deep buried hill,low-permeability hydrocarbon reservoir,conglomerate mass and igneous rock. As the exploration activities move in depth,exploration objectives are more and more complicated,which gives new challenges to wellbore exploration technology.Based on the brief review of exploration associated technologies and achievements over past three years,this paper presents the technical requirements against current technology bottleneck restricting exploration development and determines future technical targets.
