吉林油田老井复查评价方法和实施效果

Review Evaluation Method for Old Well in Jilin Oilfield and Its Implementation Effect

在油田发展历史的勘探阶段,由于受当时勘探技术条件的限制,使一部分老井尚有大量的油气资源未被发现。现代勘探技术为彻底试油、发现新的油气层提供了可能性。在复查大量老井的基础上,对5口老井进行恢复试油,其中3口井获得工业油流,取得了良好的经济效益,为吉林油田增储上产作出了重大贡献。

In exploration stage of the oil development history,because of the limit by exploration technology condition,lots of oil and gas resources in parts of the old wells have not been discovered. Modern exploration techniques provide the possibility for discovering the new oil and gas layers by through full. On the basis of the review of a large number of old wells,among five old wells conducted on recover oil test, three wells of that obtain industrial oil flow,and good economic results are achieved.
