Application of fracture detect technology to Tahe oil field

In view of low natural productivity and great anistotropy characteristics of Tahe oilfield,and acid fracturing design is based on seismic data.Detect fracture orientation,fracture length and fracture attitude from micro-seismic signal received by surface geophone.It can reform orientation of current crustal stress,provide foundation for fracturing effectiveness and acid fracturing design.Field experiment shows that this technology can effectively detect fracture orientation,length and attitude,and can overcome affect of well depth.
