黄沙坨地区火山岩储层研究及预测
|
摘要
黄沙坨地区位于辽河盆地东部凹陷中段 ,它的沙三段火山岩具有很好的油气藏形成条件。在特定的构造背景和油源条件控制下 ,火山岩储层的发育特征是本区油气藏勘探的关键 ,重点对火山岩储层的岩石学、储集空间、储集物性等特征进行研究。运用测井响应法、地震相分析法和波阻抗值法识别粗面岩储层 ,进而运用波阻抗和电阻率反演方法预测粗面岩储层和其裂缝的分布状况 ,指导勘探部署。通过不断的勘探实践 ,建成了以粗面岩为单一目的层的千万吨级储量规模的黄沙坨油田 ,同时指出了本区火山岩油气藏今后的勘探方向在其东南和西南两侧。
Huangshatuo area is located in middle part of east sag in Liaohe basin.In this area,volcanic rock of S_3 has very good oil-gas reservoir forming conditions.Under the control of special structural background and oil source,development and characteristic of volcanic rock reservoir are the key to oil-gas reservoir exploration.This paper lays emphasis on researching petrology,reservoir space,physical properties of volcanic rock reservoir.In addition,three approaches,such as log response method,seismic facies analyzing method and wave impedance value method,are used to distinguish trachyte reservoir and two approaches.Wave impedance inversion method and resistivity inversion method are applied to forecast distribution state of trachyte reservoir and fracture.Through continuous exploration and practice,Huangshatuo oil field has been built with reserves of ten millinos of tons and a single trachyte reservoir.This paper also points out that the future exploration direction of volcanic rock reservoir will be the southeast side and the southwest side of this area.
