direct fracture
3.Direct contact radiation group:Self-designed round direct radiator was used to irradiate the fracture of left radius(diameter 10.3 m,frequency 915 MHz,power 0-10 W,microstrip antenna,block construction,standing wave coefficient < 3,patent number zl 00324703.1)for 10 minutes at 5 W,5-10 ℃,once daily.
4.Based on estimating the type of filtration by constructed G and ψ fraction, and determining the fracture closed point, the parameters such as the geometry of fracture, the leak-off coefficient can be calculated, and furthermore it can direct the acid fracturing design and improve the acid fracturing technology.
