复合压裂技术是将讥能气体压裂和水力压裂相结合的一种新型增产增注技术。文中通过对复合压裂的技术特点和增产机理的分析,讨论了各自的优点,有效地降低了地层的破裂压力,增加了裂缝的渗流面积。根据复合太裂工艺的设计原则,研究了压裂施工中影响施工质量和压裂效果的几个关键因素(压力上升时间、压力峰值和压力持续时间) 。
Compound fracturing is a newly simulation of production
well and rejection well , It connects hydraulic fracturing and
high energy gas fracturing ( HEGF ) . Analysing technical
characteristic & mechanism of enhancement and discussing
each advantage ,we think it reduce fracturing pressure and
increase filterated area. According to the design - principle of
this technics , we study several factors of key which affect
compound fracturing including pressure risetime peak value
and duration of pressure.
