Research On Design And Key Parameter Optimization Of Horizontal Well Multi-stage Fracturing

Ordos Basin is rich in natural gas resources,which has great potential and good prospects for development.Linxing block sandstone gas field is located in the eastern part of Ordos basin and has obvious characteristics of low-permeability,high seepage resistance,poor connectivity,limited pay volume,and low natural production capacity.How to develop such reservoir rapidly,economically and efficiently has become an issue.So how to apply fracturing operation with optimized fracturing results on the block is becoming more and more important.After fully investigating research of horizontal well fracturing theory and technology at home and abroad,the aim of this study is to improve the success rate of horizontal well fracturing and to optimize fracturing effect.This paper has completed collection,analysis and research of reservoir characteristics,and optimized the overall fracturing proposal by means of literature research,experimental analysis,software simulation and mathematical calculation.Fracture and operations parameters are optimized,some suggestions are given,and some principles and conclusions are obtained.This paper analyzes geological parameters of a horizontal well,establishes a geological model using fracturing software and carries out fracture stimulation,and forms an overall fracturing design scheme.Fracturing operation went on well as the schedule,which proves the whole proposal has a certain significance and reference value.
