Study On The Main Controlling Factors Of Reservoir-formingof Fuyang Formation In Xingbei Oilfield Of Daqing Placanticline

Daqing changyuan geographical location in the north of songliao basin in the central depression area, is a complete secondary structure, after more than 50 years of oil and gas exploration, daqing changyuan in daqing oil field the main oil-producing, has long been a high-profile[1]. The study area is located in the songliao basin in the central depression area of daqing changyuan almond post tectonic units, its vast terrain, the oil source is rich, according to the present situation of exploration and development, the region’s resources in the future development potential is tremendous.Therefore, this article collects and analyses the 26 new Wells of drilling, logging, testing, and geological data, 3 d seismic multi-attribute analysis and many methods of inversion, the new wellblock horizon and fault further detailed interpretation; Master the structural characteristics and tectonic evolution in the study area in detail and analyzes the relationship with oil and gas migration and accumulation.Development effect of apricot, through 69 wells development experimental zone of the evaluation, analysis of the reservoir and the using condition, combined with the reservoir characteristics of the whole reservoir classification standard is put forward and the development of sand body size and unicom. And according to the core phase- log facies analysis research, on the basis of studying fine description of cores, divided into sedimentary microfacies, determine the fu Yang reservoirs in the study area mainly developed delta plain and delta front subfacies of underwater distributary channel and underwater distributary channel sand body, and sand body distribution rule were determined.Comprehensive various interpretation result, establishment of reservoir section7, analysis of oil and water in the section and space distribution rule, summarizes the types and distribution characteristics of oil accumulation; And in accordance with the principle of favorable target area selection, Favorable target area divided into 5 pieces, with a total area of 29.77km2.
