鄂尔多斯盆地大牛地气田下石盒子组地震储层预测技术的研究和应用
|
摘要
鄂尔多斯盆地大牛地气田属低孔、低渗、致密储层型岩性气藏,储层砂体较薄且纵横叠置,导致储层相变频繁、非均质性强,且与围岩的波阻抗差异小,因此精确地预测含气富集区带和提高单井产量一直是大牛地气田勘探开发中的两大难题。本文在充分研究大牛地气田储层特征和细致对比各种地震储层预测技术的基础上,精选多种储层预测技术对该地区下石盒子组储层进行了预测,取得了良好的应用效果。
The Daniudi gasfield in Ordos basin belongs to lithologic gas reservoir characterized by low porosity,low permeability and density,the sand bodies of reservoir is thinner and overlapped vertically and horizontally,leading to frequently change the reservoir facies,have strong non-homogeneity and be smaller difference of wave impedance with country rock.So,such two difficulties as accurately predicting the gas-rich zone and improving the production in single well always exist in exploration and development of Daniudi gasfield.Based on fully studying the characters of reservoir of Daniudi gasfield and carefully correlating various reservoir-predicting techniques by seismic,the paper carefully selected multiple reservoir prediction techniques to carry out prediction of Lower Shihezi Formation reservoir in studied areu,which achieved better effect of application.
