Since fracturing technology used in oil production,making the production of oil fields have a very significantly improved,especially for low permeability oilfield block,the effect is particularly evident.However,due to the diversity of development of various strata of the geological structure complexity,as well as existing fracturing technology makes fracturing each region has its own uniqueness and therefore adaptability study on the fracturing and fracturing destination tier scheme it is particularly important,directly related to the fracturing effect.In this paper,the application of the current domestic and foreign fracturing technology research and analysis,and from the viewpoint of reservoir conditions,equipment requirements and economic benefits,their applicability in Yanchang Oilfield were analyzed.Fracturing geological characteristics of the area studied and understanding.Collect,collate,statistics Qi,Yongning,fixed edge,Jingbian,Zhiluo sub north six blocks long 6,long 2 reservoir fracturing and fracturing technology to adapt well to all informative studies on the various reservoirs for fracturing process parameters on the basis of the evaluation provided.Qi of the currently available,Yongning,fixed edge,Jingbian,Zhiluo,fracturing data sub-north six blocks totaling 886 fracturing wells,testing data,reservoir production performance data in accordance with the classification of were finishing,statistical analysis.The main study the relationship between the fracture parameters and test oil production and between physical parameters and test reservoir oil production between electrical parameters.Adaptability study conducted fracturing process.It focuses on the crack propagation law currently under fracturing process conditions and analyzes its geological suitability.In the ultra-low permeability reservoirs,mainly from the increase of reservoir reconstruction longitudinal extent of the penetration depth of the cracks and fracture conductivity three aspects,we put forward the corresponding technical solutions;in bottom water reservoir in order to avoid fracturing process communication. |
