滑溜水压裂液携砂稳定剂性能研究

A slick water fracturing fluid carrying sand stabilizer performance research

滑溜水压裂是国外致密油气开发重要的增产措施,压裂液体系携砂性是压裂过程重要的性能之一。本文对现用延长气田滑溜水压裂液聚合物体系中加入携砂稳定剂,筛选了携砂稳定剂类型,优化了携砂稳定剂加入量,研究结果表明,5NS携砂稳定剂效果最佳,在压裂液聚合物浓度为0.1%时,加入0.2%的携砂稳定剂,携砂效果最佳。

Slickwater fracturing is tight oil and gas development important measures of foreign production,The sand carrying capacity of the fracturing fluid system is one of the most important properties of the fracturing process.This article by using the extended field slippery water fracturing fluid polymer added sand stabilizer,The type of sand carrying stabilizer was screened.The addition of sand carrying stabilizer was optimized.The results of the study show that 5NS sand stabilizer has the best effect.When the polymer concentration of the fracturing fluid is 0.1%,With the addition of 0.2%sand stabilizer,the effect of sand carrying is the best.
