Abstract EN
Shale gas is an important unconventional energy resource that needs large-scale fracturing to form industrial deliverability.
The evaluation of reservoir fracability plays a key role in the optimization of the sweet spot, the design of multistage fracturing, and the prediction of economic benefit.
Based on volumetric fracturing, the study proceeded from the fracture complexity of the fractured core, and the bursting pressure experiment technology using the constant strain rate method was established.
After the core has fractured, the fracture morphology was extracted and the fracture parameters including fracture area ratio and fracture declination dispersion were calculated to construct the fracture complexity of the pressed core.
Combined with the core strength, the fracability index of the core was determined to evaluate the reservoir fracability.
This method can represent not only the fracturing effect but also the fracturing difficulty.
Compared with the monitoring data of hydrofracture-induced microseism of the sample well, the core fracturing index was found to be in good agreement with the actual fracturing effect.
This method is more reasonable than the traditional brittleness index method and rock mechanics parameter method.
