摘要
利用室内物理模拟试验研究了水力喷射裂缝的形态,通过对水力喷射后井筒周围的应力应变分析,阐述了水力喷射松弛近井地带应力集中、提高近井地带渗流能力的增产机理。现场应用实践表明,水力喷射增产技术可以起到近井地带解堵和油井增产的良好效果。
The fracture morphology made by hydraulic jetting has been investigated by using laboratory physical simula-tion experiments.Base on the analysis of stress and strain near-wellbore scale after hydraulic jetting,the stimulation mechanisms that could release stress con-centration and enhance percolation capacity near-wellbore was expounded.The field application shows that the stimulation technology by hydraulic jetting could improve the effect on broken down near wellbore and oil well stimulation.
