Considering the geological features of the tight sandstone reservoir of Fuyu oil layer, Northern Songliao Basin, some key techniques of horizontal well design platform were developed based on the geological studies in the pilot development projects. These techniques attached importance to the key controls in geological design of horizontal wells by using such techniques as accurate delineation of the structural features in depth domain, fine characterization of “sweet spot” sandstone distribution, quantitatively fine description of channel sandstone geometry and optimum horizontal well design based on refine 3D geological model, which laid the solid foundation for locating the horizontal wells. The successful results were attained in horizontal well drilling in the primary stage of pilot project. The availability of the reservoir of tight channel sandstone within Fuyu oil layer was raised, the production of individual well and single well controlled reserves were greatly enhanced combining with volumetric fracturing stimulation, and support for economically tapping the tight oil in Daqing oilfield was securing.
