摘要： Hydraulic fracturing has been contributing a lot to raise oil/gas recovery. Production well performance, coring observations, and laboratory core tests indicate there exist microfractures in Yanchang group formation of Trias in Ordos basin. The existing of the microfractures can cause serious fluid loss and sand fill up, thus, the propped fracture length is much smaller than the expected value given by the design, and the treatments can not meet the demand. Therefore, in order to improve the effect of hydraulic fracturing, it is suggested that the several measures be taken, such as the pad volume and pump rate be increased, the silt be added in the pad, temporarily blocking treatments be applied.
