更新井

对更新井吸水能力的认识

Understanding to water injectivity of renewal wells

应用此项技术比钻更新井、调整井相对容易，而且经济可行。

Apply this technique is more easy than drilling renewal well and adjusting well opposite , and economy can line .

与常规开窗侧钻、套管补贴和打更新井等措施比较，衬管固井技术扩大了应用范围、降低了施工成本。

Compared with such measures as conventional sidetracking , casing patching and redrilling , the liner cementing technology has wider application range and can cut down the operation cost .

为避免钻更新井的高投入，工程上一股采用修复方法使套损井重新恢复生产，因此，套损井的修复也已成为油田工程的重要任务之一。

For saving the high expenses of drilling the renewal well , the repair for the casing damage well have became one of the important mission of the oil-field engineerings .

对于井间干扰的传统认识需要更新：井间干扰是注水见效的必要条件；

Old conventional ideas should be given up while new ideas should be established : interference among wells is requirement of injection results ;

介绍了文中复杂断块油藏的地质特征，论述了双靶定向井、侧钻井、注水井更新、井冈重组、注水井调驱等工艺在文中油田的应用及效果。

Geologic characteristics of complicated fault-block oil reservoir in Wenzhong area are introduced . Application and effect of some technologies of double target directional well , sidetracking , updating water injector , well pattern recombination , adjusting displacement by profile control of water injection wells are discussed .
