摘要

针对压裂工艺特点,研究了高聚物滤饼、压裂液残渣、粘滞性流体和液体表面性能对支撑裂缝导流能力的影响,为进一步认识地层污染机理,制定有效的水力压裂保护技术措施,提高压裂改造效果,提出了科学的试验依据。

Abstract

Depending on the Behaviors of fracturing technologies , this paper presents the impact of polymer cake , fracturing fluid residue , viscous fluid and fluid surfactant performance on propped fractures conductivity. Experimentally scientific data have been delivered to further understand the damage mechanism and resort to effectively technical protection measures of hydraulic fracturing , and improve the fracturing effect .
