| 摘 要： | 通过研究区内大量岩心铸体薄片及物性等资料分析，对小南沟区延长组主要产油层组长6^1储集层的岩石学特征、物性特征及孔隙类型等进行了研究，分析了储层特征及其影响储层储集性能的主要控制因素。结果表明，三角洲前缘亚相沉积的长6^1储集层具有结构成熟度高而成分成熟度低的岩石学特征．主要孔隙类型为原生粒间孔和次生孔隙，沉积环境、成岩作用是影响该区储集层物性的主要因素。

| Abstract: | By analyzing the data of drilling cores, costing thin sections and physical property, the paper studied the petrology characteristics,physical property,pore type and so on of Chang 6^1 reservoir as well as the reservoir characteristics and its controlling factors.The results showed that the petrology characteristics of Chang 6^1 reservoir are high maturity of structure and low maturity of composition. The main types of pore were primal grain pore and secondary pore, and the main controlling factors were sedimentary environment and diagenesis. |
