| 摘 要： | 用人工合成油层水；在歧口１８－１油田油层岩心上，进行了岩心速敏性流动试验．用人工合成油田海域内的海水和钻井过程中钻遇的馆陶组水层水为注入水水源，并在国内首次参照英国岩心水敏性评价方法，进行了岩心水敏性流动试验评价，同时分析研究了流出物颗粒含量和尺寸大小．观察分析了海水、水层水分别以不同比例与油层水混合时的结垢程度．本文研究为正确选择注入水速度和注入水水源，提供了理论依据．

| Abstract: | The tests of flow velocity sensitivity are conducted at room temperature on thecores with imitation reservoir water.According to the British method,water sensitivity testsare also conducted with imitation sea water and GT fresh water.The content of impurities andtheir sizes in flowout,the amount of scales produced by sea and GT water mixed withreservoir water in different proportions are observed and analyzed.The results indicate thatthis reservoir has no velocity sensitivity.Both sea and GT water produce clay swelling.andsea water does more. GT can water is a good injecting source and proper clay inhibitor has tobeadded |
