针对特低渗透油层注入压力升高快，注水量递减快的特点，在大庆朝522区快进行了单井增注试验.结果表明，朝82-152井注入表面活性剂体系后，既改变了吸水剖面状态，增加了吸水厚度，又提高了注水量，与试验前相似的注水压力下比较，提高注入量57%，有效期是常规增注措施的1倍以上，累积增注是常规增注措施累积增注量的3.44倍 |

Aimed at the typical extra low permeability reservoirs where injection pressure rises and injection rate decreases fast,the technique of lowering injection pressure and enhancing water injection of lowpermeability reservoirs is tested on well Chao 82-152 in Chao 522 tract of Daqing.Desirable effect is achieved shortly after the injection of this surfactant system into the target reservoirs.Desirable effect is achieved shortly after the injection of this surfactant system into the target reservoirs.Water injection profile is improved,water absorbing thickness is increased and at the same time,water injection rate is enhanced.Under water injection pressure similar to that prior to the field test,water injection rate is in creased by 57%,valid period is prolonged by 100%and cumulative increment of water injection is 3.44 times as large as that of conventional stimulating measures. |
