Damage Analysis of Container Rock in Peripheral Low Permeable Oil Field of Daqing

In this article, the types of damage of container rock resulted from the pressure loss, organic scaling, inorganic scaling, sensitivity of container rock and solid particles was discussed, and typical examples of the damage of container rock and the effects of corresponding safeguard were analyzed, and the following suggestions of the safeguard of the container rock were brought forward;waterflooding should be taken at an early stage for energy maintenance in low permeable oil field, high quality water should be used to ensure the oil layer's ability to absorb water stably,high grade operating fluid should be used to decrease degree of damage and a sensitivity database plus an intelligent distinguish system be founded.
