| 摘 要： | 通过岩心自吸水实验研究 ,表明南翼山某区块裂缝性储层有强的自吸水能力 ,吸水速度快 ,在2 0h内即可达到较高的自吸水饱和度 ,终吸水饱和度平均为 5 4.5 % ,终吸水驱油效率平均为 37% ;且黏土矿物含量越高 ,吸水量越多 ,岩心膨胀越严重 ,平均体积膨胀 4 .5 % .自吸水后对储层渗透率伤害严重 ,平均可达到 81.8% .因此 ,在开发过程中应尽可能减少水侵入储层

| Abstract: | The water-intake capacity of the fracture reservoir in some tract in Nanyishan is experimentally studied. It is shown that, the fracture reservoir has high water-intake speed, it can reach to higher water saturation within 20 h, and final average water saturation is 54.5%; final average hydroscopicity displacement efficiency is 37%; the higher the clay mineral content in the reservoir, the greater the water-intake quantity increases and the more the increase of the volume of the cores; the average volumetric expansion rate of the cores is 4.51%; hydroscopicity has serious damage to reservoir permeability, and the permeability reduces by 81.87% on average. Therefore, water invasing into reservoir should be reduce as far as possible in the process of development. |
