渤海湾盆地渤中28-2南油田群鸟足状浅水三角洲识别与沉积演化
Identification and Sedimentary Evolution of the Shallow Water Delta of Bird-foot in Bozhong 28-2S Oilfield Group of Bohai Bay Basin
摘要
Abstract
Based on the regional sedimentary environment, core description, the analysis test data of inside and outside of the core chamber, mud logging data and logging information, combined with the sedimentary model of the Tertiary period of the central-southern part of the Bohai Sea, and the fluvial facies-meandering stream, limnetic facies-delta deposit and the characteristics of the shallow-water deltadeposit, as well as the facies markers and the practical information of the BZ28-2S oilfield group, it is believed that a lake phase shallow water delta has been formed at the Lower Minghuazhen Formation of the BZ28-2S oilfield group, which is mainly shaped in bird foot delta, differing from meandering river deposit and typical delta deposit.A meandering river deposit extends towards the underwater lake facies on the plane, mainly in the form of channel deposits featuring small lake basin, shallow water, low power, weak waves and shore current effects, no tide and small lake water density.This understanding has important guiding significance for the rolling prospecting and development of oil fields.关键词
