Abstract
Based on the core observation and particle size analysis of T2k2 in the field of Well Hong 87 of the Hongshanzui oilfield in the Junggar Basin, this paper identified T2k2 in the field of Well Hong 87 as the braided river deposits according to sedimentary facies marks. By dividing single well phases, contrasting sections and analyzing plane phases, this paper also presents the map of the sedimentary facies section of T2k2 in the field of Well Hong 87 and has confirmed that a fault-lithologic reservoir is located at the oil boundary in the western region, which is controlled by sedimentary facies. Therefore, the problem of oil-gas reservoir controlling factors has been solved.
