摘　　要：通过对胡状集油田注水开发前后分析化验资料的对比 ,在注水开发过程中水岩作用试验模拟基础上 ,结合开发生产实际情况 ,探讨了其注水开发对储层孔隙度、渗透率、岩石密度、沉积物粒度及孔隙结构的影响。认为在注水开发过程中 ,由于受注入水的长期冲刷 ,储层孔隙结构发生了较大的变化 ,储层孔隙度、渗透率分布范围有所改变 ,造成了储层平均渗透率的升高 。Through comparison of assay data both before and after waterflooding in Huzhuangji Oilfield, the effect of waterflooding on reservoir porosity, permeability, rock density, deposit granularity and pore structure is approached on the basis of experimental simulation of water-rock effect during the waterflooding in combination with production practice. It is considered that during waterflooding, because of prolonged flushing resulted from waterflooding, the reservoir pore structure is varied greatly, and the reservoir porosity and permeability distributional ranges are changed as well, by which the raising of the average reservoir permeability is caused and greater changes are taken place on the reservoir physical property.
