基于正交设计与统计分析的注水井储层伤害预测
Prediction of Formation Damage of Water Injection Well Based on Orthogonal Design and Statistical Analysis
摘要
Abstract
A calculation of formation capacity in QK oilfield was carried out to identify the distribution of main water injection layers.A comprehensive core flowing test based on orthogonal design with 1 5 core samples (2 000 mD approximately)was carried out and the core permeability damage rate indicated that the damage degree was caused by particle size distribution, concentration and oil concentration.Take all these factors into consideration,the impact on the damage degree in decreasing order was oil concentration,particle concentration and particle size.Meanwhile damage rate was predict applying statistical analysis under other conditions then the error range between the predictive value and the true value,was obtained and verified. The results can be concluded that when particle size,concentration and oil concentrations were of 4 μm,3 mg/L and 18 mg/L or 4 μm,7 mg/L and 1 5 mg/L,damage rate were 22.5% and 25%.关键词
