摘要
Chunfeng Oilfield is located in Chepaizi slope belt in the western part of Junggar Basin,with consealment strong,reservoir thin and oil heavy.Polyphase fluctuation and ultra denudation of the Chepaizi uplift has controlled the distribution of residual formations.Positive-sequence sedimentation overlying controlled the reservoir-seal assemblage style and the coupling relationship between tectonic evolution and sedimentation has controlled the development and distribution of trap.Hydrocarbon passage framework is vertical communication of source fault,lateral transfer of blanket sand,vertical adjustment of adjusting fault.Enriched hydrocarbon accumulation model of Shawan Formation is far source hydrocarbon supplyment,fault blanket transportation,reservoir control of formation lithologic trap.High-precision three-dimensional seismic exploration and HDNS development are applied successfully and exploration development with high speed and high efficiency is realized in Chunfeng Oilfield.Proved geological reserves is 8208 million tons and constructed annual oil production capacity is 0.4 million tons.
