The shale-fractured oil reservoirs in Qingshankou Formation of Gulong area are the important displacing region in Daqing Oilfield, so it is urgent to optimize the effective layers and favorable intervals with the help of geo- physical well logging technologies. Therefore on bases of the understandings of the reservoir characteristics and e- valuation difficulties, the following problems are explored： identification of the overpressure layers, quantitative cal- culation of TOC, evaluation of the rock brittleness and so forth. In the end, the identifying method of the effective layers in the shale-fractured oil reservoirs is established. Much better effects are achieved in the evaluations of the old well fracturing and new horizontal well drilling by means of the method.
