| 摘 要： | 由于固井质量不合格或是套管破裂、错断引起的油井和水井套返污水，造成了吉林油田老油区普遍的环境污染。从１９９０年开始，通过反复的摸索和试验，提出并逐渐完善了两种切实可行的治理方法，即封堵剂法和封隔器法。实践证明，效果良好。

| Abstract: | Owing to well cementing not conforming to standard or casing rup-ture and misplacement leading to reversed flow outside casing in oil wells and water wells,there was rather widespread environmental pollution over old field region in Jilin Oil Field.Since 1990 through repeated tests by trial and error,two feasible control meth-ods,have been raised and gradually perfected, namely method of using plugging agents and that of using packers. Good results have been obtained in field demonstration. |
