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.
