| 摘 要： | 为了解决油房庄长1油藏目前注水井注水压力普遍偏高、注水困难、地层压力下降快、增注措施后有效期短等问题,从地层特性、注入水水质、机杂堵塞、结垢等方面评价了可能对储层造成的伤害及伤害程度,得出了该区长1油藏伤害主要是结垢伤害,最后提出了一些建议.

| Abstract: | At present,the water injection pressure of Chang-1 reservoir in Youfangzhuang is higher,theformation pressure rapidly drops,and the valid period of the measures for increasing water injectionis shorter.To solve these problems,the possible reservoir damages caused by formation property,the quality of injectedwater,the plugging of mechanical admixture,scaling,and so on andthe damage degree of themare evaluated.The results showthat the mainfactor caused the reservoir damage is scaling.Finally,some suggestions for re-ducing reservoir damage are presented,which provides basis for selecting proper plugging-removing and waterinjection-increasing measures. |
