In recent years, the development of the oil fields of West Daqing peripheral multi-reservoir-thin, poor physical properties, developmental instability, water distribution and other characteristics of the complex seismic techniques influenced by the resolution limitations of such thin reservoir prediction , the logging technology division of the reservoir and to identify fluid reservoir thin, with mud and calcium a variety of factors interfere to some extent reduce the coincidence rate of interpretation. Especially the past two years to develop in Puxi Oilfield water - layer of low permeability reservoir, at home and abroad for the development of such a reservoir is in the exploratory stage. Therefore, set up a special Puxi Oilfield complex reservoir fluid identification and reserves utilized the method of \perforation and water injection program preparation, has made the following achievements: 1, analysis of the logging response characteristics of the area that the grapes spend reservoir of low resistivity reservoir reservoir thin to thin interbedded mainly high shale content and irreducible water saturation caused; high resistivity water layer is denser reservoir, calcium and containing residual oil caused; 2, developed a classification Plate semi-quantitative cross-graphics version of the law and the interpretation of pyrolysis parameters established standard suitable geological features of the ultra-low permeability reservoir fluid identification and interpretation methods; 3 for earthquake prediction technology is difficult to accurately describe the thin and poor reservoir development status, resulting in drilling actual risky, based on early regional geological studies and favorable block preferred, according to earthquake prediction of reservoir distribution, to strengthen geological studies, fine preparation rigs running program, in accordance with the overall evaluation batches implementation, tracking drilling \to ensure that the effect of oilfield development; 5 to improve the method of preparation of the water injection program, improve the adaptability of a water injection program complex reservoirs in. The results of this project to solve the \
