Log data of some wells with tuffaceous sandstones in the same block are processed and interpreted as well as compared with oil test data. The consistency between the calculated reservoir saturation and the oil test result is better.

对同一区块多口井的南屯组凝灰质砂岩进行解释并且与试油资料进行分析对比，计算出的含水饱和度与实际试油的对比显示出很好的一致性。

The secondary pores of the sandstones were formed by the dissolution of the aluminosilicate, tuffaceous interstitial material and carbonate minerals effect by the carbonic acid and organic acid produced in late diagenesis stage. Hydrocarbon emplacement and tectonic thermal event act a positive role in the preservation of the primary pore and the formation of the secondary pores.

砂岩次生孔隙主要是成岩晚期阶段的碳酸以及有机酸对长石等硅酸盐矿物、凝灰质填隙物以及碳酸盐矿物的溶蚀造成的，油气侵位及构造热事件对原生孔隙的保存及次生孔隙的形成起到了积极作用。

The tuffaceous sandstone volume model needs to be established as the Nantun reservoir of Hailar Basin generally contains tuffaceous sandstones and the reservoir physical properties vary in different blocks.
