随钻声波测固井质量刮管一体化技术在渤海某油田应用

Integrated Technology Application of Acoustic LWD Cementing quality and Casing Scrapping in a Bohai Oilfield

海上油田大斜度井日益增多,而大斜度井固井质量评价对井控安全、完井射孔、后期老井开窗侧钻等关系重大。随钻声波测井工具不受井斜限制、操作简单,可获得高质量的声波数据资料。本项目将随钻声波测井技术与完井刮管作业相结合,在刮管作业的同时进行固井质量评价,并在渤海油田某区块成功运用,获得很好效果。

There are more and more highly deviated wells in offshore oil fields,which cementing quality is closely related to the safety of well control,completion perforating and sidetracking operation.The acoustic LWD tool is not restricted by deviation and is easy to operate,thus high quality acoustic data can be obtained.This project combines acoustic LWD technology with completion scraping operation to conduct cementing quality evaluation at the same time of scraping operation,and has been successfully applied in a block of Bohai Oilfield with good results.
