[0145] The X well section in a shale development demonstration area in Southwest my country was selected. The vertical depth of the horizontal well was 4276m, the horizontal section was 800m long, the effective thickness was 32m, and the formation fluid pressure was 42MPa. According to the analysis of core experiments, the horizontal and vertical permeability are 2.1×10 -3 μm 2 , 4.9×10 -3 μm 2 , 2.8×10 -3 μm 2 , the comprehensive compressibility coefficient of rock is 1×10 -4 MPa -1 The vertical and horizontal principal stresses are 145MPa, 121.6MPa, and 105.0MPa respectively; the natural crack cohesion is 17.5MPa, the internal friction angle is 25°, and the intersection angle is 20°; the average tensile strength is 6.56MPa. Now use φ177.8δ12.65 bare casing, slippery water fracturing fluid (flow pattern index 1.0, drag reduction rate 70%) divided into 15 sections, 3 clusters, fracture cluster spacing 15m; effective perforation holes 20 holes, aperture φ12 ; The pre-seq...
