摘要
测试压裂又称小型压裂试验, 是通过进行一次或两次以上的小型压裂试验, 同时
采取与之相配套工艺技术措施(如阶梯升/降排量、携砂段塞、瞬时停泵、微脉冲试验等) , 并对
压裂压力进行分析来获取储层、裂缝的有关参数与射孔孔眼摩阻、近井筒裂缝迂曲摩阻等, 如
储层流体渗透率、压裂裂缝延伸压力、闭合压力、缝长、缝宽、压裂液造壁系数、压裂液效率等,
从而制定和修改主压裂设计、科学指导压裂施工及为压后评价提供可靠的依据。
Abstract
Test- frac is called m in-i frac. Test-frac is perform ing one o r two m in-i frac test and attachs w ith m atch ing techno logy, such as step rate test, slug test, transient stop pum p and m icro-pu lse test. Reservo ir param eter, fracture param eter, perforation friction and fracture tortuous fr iction nea rw ellbore can be obta ined through the pressure data ana lys is. It is he lpful for m aking and m od ify ing the m a in- frac design, d irecting frac operation and post-frac eva luation.
