Cenpral New 201 Station Of Daqing Oil Field Of Class Ⅱ Oil Reservoir Polymer Drive The Oil Characteristic

The polymer drives oil technology, since in my ore was put into production for industrialization in 1996, make better result , continue group oil reservoir note ,I of Portugal , is it make ideal development result lag behind to gather, return to the experiment to begin in my ore on gathering in class II oil reservoir note. After group main oil reservoir note , I of Portugal , gather, class II oil reservoir note is it gather main direction developed to drive to gather, I ore Central New 201 station is it begin the class II oil reservoir return to testing , offer practice basis for the fact that explore the class II oil reservoir note gathers the law , realizes gathering the output of driving to take over to take the lead in. After the polymer is driven , not only can expand the volume of involving but also can improve and drive oil efficiency . First, polymer can many kinds of body remnants oil of shape have, pour into water involve oil reservoir that reach, with form a cluster form , many kinds of shape , form of post and form , blind form ,etc. of detached island held hole up in of the medium remaining oil, indicate through the result of study of experiment in recent years , the polymer is driven to these kinds of remnants oil soya-bean oil certain driving the result of taking the place of. Second, mechanism its is it participate in obstruction exist to lie in, water oil than reduce fluidity, enable the polymer to drive the remaining oil of form in order to form a cluster , the increase which shears strength can be driven and taken the place of the remaining oil of written complaint of form of detached island , membrane. This text, in order to explore the class II oil reservoir note gathers the law , realize gathering the output of driving and taking over and offering practice basis. Its theoretical foundation is: (1)On return to Sa III group oil reservoir their penetrance of coefficient of variations at 0. 635-0. Between 718 , happen to be in the range that the polymer drives the oil with better result.(2)Oil reservoir quality characteristic suited to gathering and driving.(3)The class II oil reservoir development becomes and sticks together the form or a banding, when the note adopts the relation to perfect, can gather and exploit the note . Theme word: Class II oil reservoir;Gather and drive;Characteristic that become effective;Return to.
