柴达木盆地开特米里克构造第三系上干柴沟组储层特征及评价

The characteristics and evaluation of Structural reservoir of Kaitemilike in Qaidam Basin

在系统收集和整理柴达木盆地开特米里克构造第三系上干柴沟组岩心、薄片等资料的基础上,结合分析化验资料对研究区储层岩石学特征、储集空间类型、储层物性特征等研究,并对其储层影响进行分析。结果表明该区第三系上干柴沟组储层为钙质、云质泥岩和泥灰岩的碳酸盐岩储层,缝洞性储层的形成主要受岩性、构造条件的控制。最后考虑碳酸盐岩储层孔、洞、缝在储集体系中的作用,综合地质、测井进行总体评价,并结合影响储层储集性能的各种因素,尝试建立了裂缝—孔隙（洞）型储层的评价分类标准,并对研究区第三系储层进行评价分类。

On the base of collecting and arranging the structural core and the thin slice of Kaitemilike in Qaidam Basin ,conducted Keservoir petrology features. Keservoir space type and Keservoir property effect in study area combining with the test data.analysed the influence on the reservoir simultaneously,Results show that the reservoir is Carbonate reservoir containing Calcareous. Carbonaceous mudstone and Muddy limestone and Fracture cavity reservoir of The tertiary is controlled by Lithology and Structure condition mainly, lastly ,Considering the role of the pore. the hole and the seam of Carbonate reservoir in Keservoir system, conduceted the overall evaluation synthesizing Geology and Log.combining with various fators effected on Reservoir properties of reservoir,Attempted to establish the classification criteria of Seam-Pore（hole） reservoir and conduct the evaluation and classification of the reservoir of The tertiary.
