a new kind of oil soluble polymer jhxd as selective water shutoff agent was prepared based on the requirement of selective plugging in water injected oilfields.
针对注水开发油田选择性堵水的急需,研制了一类新型油溶性聚合物选堵剂jhxd。
a novel hydrophobic association polyacrylamide selective plugging agent mx10-2 was developed for the horizontal wells in luliang operation area of xinjiang oilfield.
针对新疆油田公司陆梁作业区水平井生产中存在的问题,研制出疏水聚丙烯酰胺类选择性堵水剂mx10-2。
the results showed that, the permeability of water phase decreased 85% at least, the permeability of oil decreased no more than 25%. pdz-1 has high selective plugging and a nice flushing resistance.
结果表明,该堵剂可使水相渗透率下降85%以上,油相渗透率下降25%以下,具有明显的选择性封堵作用及优良的耐沖刷性。
