Research And Implement Evaluation For The Schema Of Integral Fracturing For Yaoyingtai Oilfield In Songliao Basin

Yaoyingtai oilfield in Songliao basin is a field which has low-to-moderate pressure and low-extra low permeability. Natural deliverability of most reservoirs is low or even zero after perforation.Fracturing is an effective way to improve deliverability and get more production.For the sake of achieving economies of scale in development and enhancing economic efficiency,this paper bases on geologic characteristics and development requirements,and macroscopic and microscopic analysis of Qingshankou reservoir, presents fine haydite lowing filtration technology,linear proppant concentration sanding and varible viscosity formulation for fracturing fluid technology; by application of analytical model in FracPT,a kind of fracturing software, and analysis of pressure data from the treatment,improve the controls of hydraulic fracture; simulate development behavior by way of black oil model reservoir simulation software, and well pattern development scheme is drawn up by optimum profit analytical method,propose the planning and implementation of this field.100 wells implemented sand fracturing reformation show that the extent use of this field and production of single well is raised ,and that water flood effect is improved ,and that reservoir is exploited efficiently.
