Summary: | The invention relates to a fracture height comprehensive control fracturing method suitable for loose sandstone, which comprises the following steps of: selecting at least two of a degradation rate index, a particle size value index, a settling velocity index and a filtrate loss reduction performance index to evaluate a temporary plugging filtrate loss reducer so as to obtain the temporary plugging filtrate loss reducer meeting the fracturing requirement of a loose sandstone oil reservoir; geological factors and engineering factors are considered, and construction parameters of the use amount of the shielding agent and the floating/sinking speed of the shielding agent are optimized; and performing fracturing construction by using the evaluated construction parameters of the temporary plugging filtrate reducer, the use amount of the shielding agent and the floating/sinking speed of the shielding agent. According to the method, crack initiation of the loose sandstone reservoir can be effectively achieved, meanw |
