Then, the volume of secondary fracture system can be estimated from the volume of ,fracturing fluid, injected into reservoir layer. Assuming the matrix block is divided into plats by secondary fracture (Fig. 2), the porosity of connected natural fractures is 100% and the system compressibility of secondary ,fracturing, networks is homogeneous, ω and λ are defined as (Warren and Root 1963; Wang ...

The concentrations of crosslinkers in ,fracturing fluid, are relatively low and range from 0.5 to 250 mg L-1 . Friction reducers are added to allow ,fracturing, fluids and sand, or other solid materials called proppants, to be pumped to the target zone at a higher rate and reduced pressure than if water alone was used.

4.4. Mitigating reservoir damage by retained ,fracturing fluid, and environmental pollution by ,flowback fluid,. The retained conventional ,fracturing fluid, forms a zone with high water saturation in the microfractures or the matrix pore throats near the fractures, which affects the gas transmission and damages the gas deliverability of the gas reservoirs.

When bottom-hole flow pressure equaled formation pressure, gas well ,production, was not 0 × 10 4 m 3 /d, the angle was large, and gas well ,production, was greater. Deliverability and stress sensitivity hold a linear relationship: the stronger the stress sensitivity, the lower the deliverability of the gas well, with the stress sensitivity index from 0 to 0.06 MPa −1 and the deliverability ...
