中文摘要：
针对文10块沙3中储层的地质特点，采用试验方法对注水开发前后的流体动力地质作用对储层物性影响进行研究。分析了流体动力地质作用对储层岩石组分、储层砂岩粒度、孔喉结构、孔渗物性的影响。研究表明：沉积物呈现出较为显著的粒级缺失现象，经过长期的水驱开发，部分小孔隙转变为大孔隙的趋势较为明显，参与渗流的最小孔喉直径大大提高，孔喉非均质性变强。长期注水开发后，物性好的储层物性更好，物性差的储层则更差，储层物性呈现出两极分化的态势，”马太效应”现象明显。
英文摘要：
Reasearch has been carried out on the hydrodynamic geology effect on physical property before and after flood development through testing procedure, in view of geological feature of the middle S3 reservoir in Wen 10 Block. The effect of the hydrodynamic geology has been analysed on rock constituents, sandstone grain grade, the architecture of pore-throat in the reservoir and its physical properties. The research indicates that ： sedimentary de- posit has an apparent phenomenon of grain grade absence, over the long period of flood development, some fine pores have obvious trendence percolation increases greatly, flood development, reservoir ervoir takes on a potential of of changing into macroporous ones , the minimal pore throat diameter participating in heterogeneity of the pore-throat architecture turns stronger. Over the long period of of good property turns better and the bad one turns worse, the property of Wen 10 res- polarization, and it takes on the obvious phenomenon of Matthew.
