摘　　要：黄2井区潜4^(1)_(1)砂体经过多年的开发,由于油藏本身的特性以及后期开发方式上的不适应性,开发效果逐渐变差。通过分析砂体见水见效特征及地下水驱流场的变化趋势,找准目前存在的主要问题及潜力方向,提出针对性的调整措施。在地下流场认识的基础上,油水联动,建立“推、拉、压”三种转流场模式,促进油井二次见效。采用油井调参和水井调水,达到减弱主流线方向强度、增大次流线方向强度的目的,提高砂体的开发效果。After years of development of the Qian 4^(1)_(1) sand body in the Huang No.2 well area,the development effect had gradually become poorer due to the characteristics of the reservoir itself and the inadaptability of the later development pattern.By analyzing the water-flooding breakthrough or response characteristics of the sand body and the variations of water-flooding flow fields,the main existing problems and potential directions were identified,so the corresponding adjustment measures were put forward.On the basis of the understanding of water-flooding flow field,the oil-water linkage was established to set three flow field conversion modes of"push,pull and press"to expedite the secondary response of an oil well.The purpose of reducing the intensity of the main flow line direction and increasing the intensity of the secondary flow line direction is achieved by adjusting the parameters of the oil well and water well,so as to improve the development effect of the sand body.
