摘要

恒速压汞技术不仅可测量喉道数量,而且能同时得到孔道与喉道的信息。利用恒速压汞实验对冲积环境储层不同流动单元微观孔隙特征进行了研究。恒速压汞分析表明:不同流动单元喉道半径和有效喉道体积差别明显;储层孔隙半径差距明显;有效孔隙体积差异并不明显;储层孔喉半径比差异明显;相对而言Ⅲ类流动单元有效孔隙喉道数更多。对于中孔中渗储层来说,影响流体流动能力的因素主要是喉道大小。因此在油气田开发中,应根据不同流动单元的不同微观孔隙结构特征,采取不同的开发策略。应用该方法在孔南地区官195断块取得了较好的开发效果。

Abstract

Constant velocity mercury injection technique can not only measure the numbers of the pore and the throat, but also get the radiuses of the pore and the throat. The porosity characteristics of various flow units in Kongnan area are studied by means of rate controlled mercury penetration method. The results indicate that, the throat radiuses and the effective throat volumes of different flow units are significantly different; the pore radiuses of different flow units are significantly different, but the effective pore volumes of different flow units are not significantly different; the pore/throat radius ratios of different reservoir flow units are significantly different; the Ⅲ kind of flow units has relatively more pores and throats effective. In summary, the main factor affecting the flow capacity of alluvial environment is the throat radius. According to different micro-pore structures of the different flow units, it should take a different development strategy. After the implementation of the measures,it has a good development result in Guan-195 block of Kongnan area.
