目前 ,利用酶可以在油气井的井眼或者地层中产生某些化学剂 ,进行增产、增注、控水 (堵水、调剖 )或者防砂。利用酶控制化学剂的形成 ,可以使化学剂在地层内均衡分布 ,而且具有极好的层段覆盖率。 At present, some chemicals can be produced in the wellbore or formation of oil and gas wells by using enzymes to increase production, increase injection, control water (block water, profile control) or prevent sand. The use of enzymes to control the formation of chemical agents allows for a balanced distribution of chemicals within the formation with excellent layer coverage.
