摘要
通过对岩芯、薄片及沉积微相等资料的分析，结合压汞测试结果，重点分析了辽河盆地荣３７块气田下第三系沙河街组和东营组砂岩储层的孔隙类型、孔隙结构及其非均质性特征，指出粒间孔及粒间溶蚀扩大孔为主要储集空间；提出９种孔隙结构类型，其中东营组曲流河点坝微相砂体孔隙结构类型良好。对储层进行了层内、层间及平面非均质研究，指出天然气储层平面及层内非均质性强，而层间非均质性相对较弱。依据研究结果对今后开发该气田提出了建议。
This paper reviews some of the important results of the core, rock section, microfacies and mercury injection method. The pore types, pore texture and heterogeneity of Eogene system reservoor in Rong 37 block are comprehensively analysed. Nine pore texture types are acknowledged. The interparticle pores and interparticle solution enlarged pores are the chief pores. The point bar of Dongying Group reservoir has the best pore texture. The natural gas reservoir heterogeneity of horizontal and interface is heavy, and the interlayer heterogeneity is thin. In the end, the developing methods of this natural gas field are suggested based on the results.
