“…Under the same particle size and closure pressure, with the increase of sand concentration, the fracture width increases, resulting in higher conductivity than that of low sand concentration. At the same time, it also proves that the proppant with higher roundness and sphericity has lower breakage rate 32,33 .…”

The performance of fracturing proppant is very important for reservoir hydraulic fracturing design, roundness and sphericity is an important index to evaluate the performance of proppant. The higher the average roundness-sphericity of the proppant, the stronger the anti-crushing ability, and the better the fracture support effect in the formation, the greater the conductivity and the better the reservoir reconstruction effect. The traditional manual visual method is subjective and inefficient; in this paper, a new method of calculating roundness and sphericity by using image processing technology combined with particle corner mean curvature radius-multiple linear regression is proposed. Compared with the traditional manual visual method, the maximum error of the measurement results is only 5%. The samples used in the study of the effect of proppant roundness and sphericity on fracture conductivity were screened by the new method. In the process of simulating the field fracturing construction scheme, it is found that the low roundness and sphericity caused by proppant breakage in the fracture will lead to the decrease of the gap between the particles to hinder the oil and gas flow and reduce the fracture conductivity. The proppant with high roundness and sphericity can effectively reduce the breakage rate of the proppant squeezed by the formation closure pressure in the fracture. At the same time, At the same time, few scholars have studied the relationship between roundness and sphericity on crushing rate and fracture conductivity. The experimental results provide a basis for field fracturing design proppant optimization, maintaining fracture conductivity and increasing production.

“…It is well known that simulation of fracture propagation and simulation of PDA are two important tools for calculating the geometric sizes and mastering the dynamic propagation laws of fractures [37]. Both methods support and complement with each other, and work together to guide fracturing treatment.…”

After hydraulic fracturing, some treatments intended for production enhancement fail to yield predetermined effects. The main reason is the insufficient research about the fracture propagation mechanism. There is compelling evidence that I-shaped fracture, two horizontal fractures at the junction of coalbed and cover/bottom layer, and one vertical fracture in the coalbed have formed in part of the coalbed after hydraulic fracturing. Therefore, this paper aims at I-shaped fracture propagation simulation. A novel propagation model is derived on the basis of a three-dimensional (3D) model, and the coupling conditions of vertical fracture and horizontal fractures are established based on the flow rate distribution and the bottom-hole pressure equality, respectively. Moreover, an associated PDA (pressure decline analysis of post-fracturing) model is established. Both models complement with each other and work together to guide fracturing treatment. Finally, a field case is studied to show that the proposed models can effectively investigate and simulate fracture initiation/propagation and pressure decline.
