用静态和动态方法研究了锦州9-3油田注入水与油层的适应性。结果表明,该油田以馆陶组地层水作为注入水水源时,注入水与油层水的相容性较好,与地层原油的配伍性较好,与岩石的配伍性不好。体积流过量试验结果显示,当注入150倍孔隙体积注入水时,因粘土膨胀,渗透率下降达28%。若将馆陶组地层水作为注入水水源,必须在注入水中加入防膨剂以防止由于粘土水化膨胀而造成的地层伤害。
用靜態和動態方法研究瞭錦州9-3油田註入水與油層的適應性。結果錶明,該油田以館陶組地層水作為註入水水源時,註入水與油層水的相容性較好,與地層原油的配伍性較好,與巖石的配伍性不好。體積流過量試驗結果顯示,噹註入150倍孔隙體積註入水時,因粘土膨脹,滲透率下降達28%。若將館陶組地層水作為註入水水源,必鬚在註入水中加入防膨劑以防止由于粘土水化膨脹而造成的地層傷害。

Water injection and reservoir adaptabilities in Jinzhou 9-3 oilfield are studied by using static and dynamic methods.The results indicate that when formation water in Guantao formation is used as a source of water injection in the oilfield,the compatibilities of injected water with reservoir water and injected water with crude oil are better and the injected water with reservoir stone is poor.The result from the testing by volume flow overrate demonstrates that when injected water as much as 150 fold of pore volume is used,permeability is reduced as much as 28% due to clay swelling.If the formation water in Guantao formation is used as a source of water injection,swelling preventing agent shall be added to the injected water to prevent formation damage from hydrated clay swell.
