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。
Based on the analysis of core, thin slice and sedimentary microfacies data and mercury intrusion test results, the pore types and pore structures of sandstone reservoirs of the Lower Tertiary Shahejie Formation and Dongying Formation in Rong 37 block of Liaohe Basin are analyzed emphatically Heterogeneity characteristics indicate that intergranular pores and intergranular dissolution and enlargement pores are the main reservoir space. Nine pore structure types are proposed, in which the pore structure types of the meandering sand bodies in the Quyinghedian Dam in Dongying Formation are good. The in-reservoir, inter-layer and planar inhomogeneities are studied, and it is pointed out that the natural gas reservoirs have strong in-plane and in-reservoir heterogeneity while the inter-layer heterogeneity is relatively weak. Based on the research results, some suggestions are put forward to develop the gas field in the future.
