The invention provides a prepad fluid energized fracturing scheme generation method and device. The method comprises the steps that oil reservoir physical data of a target oil well is obtained, and acorresponding oil reservoir model is built up; simulation is conducted on a stratum pressure recovery condition of the target oil well under different injection rate of energized liquid based on the oil reservoir model, and a stratum pressure recovery model is obtained; simulation is conducted on an oil production condition when the target oil well is fractured under different injection rate of the energized fluid based on the stratum pressure recovery model, and a corresponding fracturing simulating model and a corresponding relationship between the oil production rate and the production timeare obtained; and the injection rate of the energized fluid enabling the target oil well to reach a highest oil production efficiency or a highest economic benefit in a preset production time is selected according to the corresponding relationship, and a corresponding fracturing scheme is generated based on the fracturing simulating model of the injection rate of the energized fluid. The method is wide in application range, the appropriate prepad fluid energized fracturing scheme can be generated aiming at the target oil well, so that the fracturing oil production rate of a corresponding oilwell is improved.
Description
technical field [0001] The invention relates to the technical field of hydraulic fracturing of oil wells, and in particular, to a method and device for generating a pre-fluid energy-enhancing fracturing scheme. Background technique [0002] With the widespread use of oil and gas, oil well hydraulic fracturing technology has developed rapidly, and has gradually become an important technical measure to improve the oil production of low-permeability oil and gas reservoirs or old wells in the process of oil and gas reservoir development. Hydraulic fracturing transmits the high pressure formed by the ground pump truck to the formation through the fracturing fluid, which ruptures the reservoir and forms artificial fractures, thereby using artificial fractures to form oil and gas flow channels in the reservoir, increasing the oil and gas drainage area and sweeping range, To increase oil and gas production, the fracturing fluid carries the proppant used to support the fracture. How...
