Problems solved by technology

Among the various horizontal well fracture design methods currently reported in the literature, they are almost limited to the optimal design of fracture spacing and fracture length, and there are few geological optimization designs for fracture location, fracture arrangement and fracture conductivity. Reports, especially quantitative geological design methods for fractures are rare

Abstract

The invention belongs to the field of gas field development and research and particularly relates to a fracturing fracture geological design method of a horizontal well of a dense gas field. The design method takes influences of factors, such as positions of fracturing fractures, arrangement modes of the fracturing fractures, lengths of the fracturing fractures, intervals of the fracturing fractures, and flow conductivity of the fracturing fractures, into account at the same time, a quantitative geological design model of the lengths of the fracturing fractures, the intervals of the fracturing fractures, the flow conductivity of the fracturing fractures is established based on the reservoir permeability, and the blank of the quantitative geological design of the fracturing fractures of the horizontal well is filled. The fracturing fracture geological design method of the horizontal well of the dense gas field is simple, strong in maneuverability, effective and practical when used for guiding fracturing fracture geological design of multistage fracturing horizontal wells of the dense gas field, and the fracturing fracture geological design method of the horizontal well of the dense gas field has good popularization and using value.

Description

technical field [0001] The invention belongs to the field of gas field development and research, in particular to a geological design method for fracturing a horizontal well in a tight gas field. Background technique [0002] The development of multi-stage fractured horizontal wells in tight oil and gas fields has become a research hotspot in the field of oil and gas development. There are a lot of published literatures about the optimization design of fracturing for horizontal wells in gas fields. Among the various horizontal well fracture design methods currently reported in the literature, they are almost limited to the optimal design of fracture spacing and fracture length, and there are few geological optimization designs for fracture location, fracture arrangement and fracture conductivity. Reports, especially quantitative geological design methods for fractures are few and far between. Contents of the invention [0003] The purpose of the present invention is to p...
