【 摘 要 】

In the operation of new well fracturing, multi-layers are opened at one time, and each layer is separately fractured by downhole fracturing tool and hydraulic fracturing method, and the fluid is discharged from each layer for production. Such fracturing technology is called a well multi-layer fracturing technology. The fracturing technology is restricted by the reservoir characteristics. The multi-layer fracturing technology of one well is an effective practical technique in the practice of fracturing and testing for the wells with the same formation and multiple layers. This technology has been applied in CK Oilfield. The daily oil production of a well with multiple fractured wells is higher than that of the combined wells. According to the data of 15 wells in a well in the CK Oilfield, the average daily oil production per well is 3.95t/d. There are 7 combined wells, and the average daily oil production per well is 1.78t/d. The average single well production multi-layer fractured well is 2.17t/d.
