The Research Of Production Technique About FuYang Oil Layer In Xing North Development Zones Xing A1 Well District Of Daqing Placanticline

With the furthure production of oil field, the production of normal oil field docs not satisfy the command of society, so there should find the reserve potential of oil field development and low porosity, low permeability fault and lithological reservoir become the key of increasing the reservoir yield. FuYang oil layer of Xing North development area is important part of oil-bearing assemblage in Daqing placanticline, which are low porosity, low permeability fault and lithological reservoir and has great oil potential. So the reservoir evaluation of Fuyang oil layer should be carried out.According to the difference of physical property, the oil bearing area in this paper can be divided into three categories: Potential area I , Potential area II, Potential area III. In order to test development potential and water injection feasibility of Fuyang oil layer, Xing North development area carried out pilot field test of Xing B1 well area. Research shows that Xing North Fuyang oil layer Potential area I has feasible waterflood development, but Xing B1 well area has limitation of small test scale. So this paper choose Xing A1 well area of Fuyang oil layer class II potential area to carry out more reserach.First, this paper deepens the understanding of geological characteristics of Fuyang oil layer, which forms the technology of subdivision and contrast of the thin layer sand bank under the control of standard layer, oil and water layer identification technology and reservoir parameter interpretation method. Next, determine the limit of advanced water injection technology and optimization of fracturing technology in oil and water wells. Then this paper analyzes the comprehensive technical methods suitable for the Fuyang oil layer in Xing North area.The study finds that the production technique of Fuyang oil layer, advanced water injection technology and optimization of fracturing technology based on geological analysis can give better guidance for Fuyang oil production. Besides, the research has better economic profit and provides successful experience for the economic and effective development of Fuyang oil layer. The study also has guiding significance for effective development of Daqing Placanticline Fuyang oil layer.
