APPLICATION OF TESTING FRACTURING IN CHANGQING OILFIELD

Testing fracturing can validly define rock mechanics parameters in given formation condition. The technology of fracture high testing can verify the quality of cement. The testing fracture used in monoblock can determine the parameters of fracturing such as construction discharge capacity, scale and parameter optimization. The smaller testing fracturing was used in Changqing Oilfield, and the well parameters were achieved such as fracture pressure, closure stress and time, filter loss coefficient etc. Matching with temperature log, it can determine the fracture high, and the fracture mode of block under the maximum discharge capacity. The basis of fracture optimization design was provided for Jing’an Oilfield by testing fracture and it also improved successful rate in refracturing in Ansai Oilfield.
