截至2003年,由老油田注入管线屡次破损引发了讨论,即如果继续开展水驱项目,必须找到最佳解决方法。考虑到吸引人的剩余储量和所有权使用期限,OakResources,Inc.公司决定更换注入管线,使用线圈式连续铝塑复合管来代替碳钢管(内外均有涂层)或有接缝的玻璃钢管来继续开展水驱。通过对不同系统的评估,总的安装费用几乎是相同的,而起决定性的因素是安装简单,井和道路停工期短,设计具有长期可靠性。2003年4月沟挖开以后,算上压力测试,安装长约1mile的外径为31/2in和21/2in混合管线只需11/2天。安装费用少于$8/ft。在一年的安装里只有两例失败,其原因都是安装过程中引起了局部损坏。
As of 2003, repeated breaks in injection lines from old oilfields led to discussions that the best solution must be found if the waterflood project continues. OakResources, Inc. decided to replace the injection line with a continuous coil of aluminum-plastic composite pipe to replace the carbon steel pipe (coated inside and outside) or seamed fiberglass pipe, taking into account the attractive remaining reserves and ownership period Carry out water drive. The total installation costs are almost the same through the assessment of different systems, and the decisive factors are simple installation, short well and road closures, and long-term design reliability. After dug excavation in April 2003, count the pressure test, install the length of about 1mile outside diameter of 31 / 2in and 21 / 2in mixed pipeline only 11/2 days. Installation costs less than $ 8 / ft. Only two cases failed in a year’s installation, due to localized damage during the installation.
