Problems solved by technology

[0004] However, logging data such as P-wave velocity, S-wave velocity, and density curves cannot fully reflect the information required for reservoir fracturing
Therefore, simply relying on the logging data obtained by conventional logging methods to optimize the staged fracturing parameters of horizontal wells often has a poor optimization effect and cannot maximize the productivity of oil and gas resources.

Abstract

The invention discloses a method and a device of optimizing staged fracturing parameters of a horizontal well. The method comprises the steps that rock elasticity parameters and mineral composition parameters of sample point strata in a horizontal well exploration work area are acquired; a rock elasticity parameter data body and a mineral composition parameter data body of the work area are acquired; based on the rock elasticity parameters and the mineral composition parameters, as well as the rock elasticity parameter data body and the mineral composition parameter data body, brittleness parameters and total organic carbon content parameters of the strata in the work area are acquired; fracture layout features and differential horizontal stress ratios of the work area are acquired; and based on the brittleness parameters and the total organic carbon content parameters, as well as the fracture layout features and the differential horizontal stress ratios, the staged fracturing parameters of the work area are optimized. According to the method and the device, the optimization effect of the staged fracturing parameters of the horizontal well can be improved, and a guarantee of the realization of maximized oil and gas resource capacity is provided.

Description

technical field [0001] The present application relates to the technical field of geophysical exploration, in particular to a method and device for optimizing staged fracturing parameters of a horizontal well. Background technique [0002] Reservoir fracturing is an effective method to improve reservoir permeability and ensure the smooth exploitation of oil and gas resources. The exploitation of oil and gas resources usually adopts staged fracturing measures of horizontal wells. The staged fracturing parameters of a horizontal well generally include the number of stages and the interval between stages of the horizontal well. The design of staged fracturing parameters is the key to the success of reservoir stimulation. Inappropriate staged fracturing parameters not only consume time and materials, but fail to achieve the effect of reservoir stimulation, and sometimes even communicate with oil and water layers, forming water channeling, which affects subsequent production and...
