摘要

鄂尔多斯盆地靖边气田东北部奥陶系马五1亚段储层在风化壳顶部,由于遭受长达130 Ma 的风化剥蚀,其经历的成岩作用很复杂。岩心与薄片分析表明,该研究区的表生岩溶作用、埋藏溶解作用和矿物充填作用对马五1亚段白云岩储集层形成的影响较大。该区主力产气层马五13 小层的成岩有利区在中—中南部及西部。

Abstract

The OrdovicianMa 51 reservoir in northeastern Jingbian Gas Field in Ordos Basin is at the top ofweathering crust. The diagenesis is complex because of weathering and denudation in about 130 Ma. Based on the analysis of core and thin slice, it is concluded that the forming of Ma 51 dolomite reservoir is dominated by hypergene karstification, burial dissolution and mineral filling. The favorable diagenesis zones of Ma 51 reservoir are mainly in the midst-central south and west of the study area.
