The Evaluation and Optimization of Particle Backflow Control Technology for Fractured Porous Sandstone
This article focuses on the specific characteristics of screen tube fracturing,and takes a typical well as a case study to conduct experi-ments on different sand control modes of screen tube fracturing.From the experimental results,it can be seen that the expansion screen tube has better flowability and is suitable for oil wells with low production capacity,high production pressure difference,and no severe sand production;The sand control accuracy is 184 μm foam metal screen pipe has both sand control and circulation capacity,and is suitable for oil wells with high production capacity and severe sand production.
