| Abstract: | According to some reservoir characteristics of Pingbei Area, such as low porosity, ultra low perm eability, low oil saturation, low formation pressure, low temperature, low productivity and shallow buried depth, the low temperature hydro fracturing fluid has been researched, and with 160m fracturing proppant radius, 15%～20% concentration of spearhead fluid, 35%～40% average sand proportion, and 15%-25%-35%-45%-55% sand-added sequence. The hydro fracturing success ration is 99.4%. So the reservoir potential has been developed fully and a great effect of stimulation treatment acquired. |
