割缝筛管防砂设计及应用

Slotted screen design and its application to oil/water wells in sand control

针对油 (水、气 )井防砂完井优配割缝筛管的需要 ,从理论研究和应用实践中 ,总结出一套割缝筛管的设计方法 ,其中包括割缝筛管的防腐设计 ;割缝筛管的防垢设计 ;基于形成砂桥来控制地层砂的设计原则和基于完全阻止地层砂移动的设计原则来进行割缝筛管的缝宽设计 ;割缝筛管的面密度的设计 (包括裸眼井用割缝筛管 ) ;割缝筛管的缝长设计。

This article sums up a series of slotted screen design methods,including the corrosion resistance design and antiscale design,and defines slotted screen parameters according to their structure and working conditions,such as slotted width and length,slotted density and type and form,slotted screen strength and material,etc.And it also gives the flow diagram of the sand control design of the slotted screen.
