【摘要】 准噶尔盆地西北缘风南地区二叠系风城组风一段云质岩类储集层,是构造背景下的岩性油气藏的主力储层。风城组储集层基质孔隙、裂缝和孔洞三种类型储集空间共存,油气关系复杂。在井资料较少、储层较薄的情况下,利用常规地震反演预测储层岩性十分困难。利用波形分类地震相分析技术对风城组风一段的地震数据道进行对比分类,能很好地反应地震信号的横向变化,以此用于岩性油藏的预测。运用波形分类分析技术对该地区油藏分布进行了研究,得到的岩性分布与地层取芯资料十分吻合,说明利用波形分类分析技术进行岩性油藏分布预测行之有效。更多还原

【Abstract】 The dolomitic reservoir in Feng1 formation is major reservoir of lithologic hydrocarbon reservoir with structural setting in Fengnan area of Permian system in Northwestern Margin of Junggar Basin.There are matrix porosity,fracture and holes in reservoir of Fengcheng formation,and relationship of hydrocarbon-bearing in the reservoirs is complex.In the forecast of reservoir lithology with the conventional seismic inversion,it is very difficult to predict the thin reservoirs variation laterally for lack of drilling wells.The seismic facies classification technology with waveform analysis adopt for classification of seismic data and response to lateral changes of seismic signals.This paper studied reservoir distribution with waveform classification technology in Fengnan area,and the predicted result coincide with the core data,hence this technique is effective to predict reservoir lithology.更多还原
