Abstract:

Member 2 of Sangonghe formation(J1s2)in Jurassic is an important reservoir rocks of lithologic trap in Moxizhuang Oilfield.Hydrocarbon accumulation conditions of Sangonghe reservoir in Moxizhuang area are researched by the technology of oil sources correlation,3D structure interpretation,well log constrained wave impedance lithology inversion and 3D geological modeling,it is concluded that source reservoir cap rock association and lithologic trap are two main control factors for hydrocarbon accumulation and distribution.Permian hydrocarbon source rocks are main sources in Moxizhuang area,and sand body of underwater channel of delta front and mouth bar are main reservoir rocks.Mudstone in Sangonghe member 1 is the regional cap rocks while the mudstone between top and bottom sand body in Sangonghe member 2 is the local cap rocks.

Key words: Moxizhuang Oilfield, Sangonghe Formation, lithologic reservoir, main control factor, Junggar Basin
