准西春风油田勘探成效分析
|
摘要
春风油田位于准噶尔盆地西缘车排子斜坡带,油藏隐蔽性强、油层薄、油稠。车排子凸起多期升降和超剥作用控制了残余地层展布,正序沉积叠加控制了储盖组合样式,构造演化与沉积作用耦合控制了圈闭的发育及展布。油气输导格架为"油源断层垂向沟通、毯状砂体横向输导、调节断层纵向调整";沙湾组富集成藏模式为"远源供烃、断毯输导、地层岩性圈闭控藏"。在对生储盖运藏认识的基础上,成功应用了高精度三维地震勘探技术和HDNS(水平井+油溶性降黏剂+氮气+蒸汽)开发技术,使得春风油田实现了高速高效勘探开发,探明石油地质储量8 208×104t,建成产油能力40×104t/a。
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.
