摘　　要：针对塔河油田酸压施工中压力异常情况,从施工曲线特征入手,分析总结压力异常原因,主要针对地层因素影响提出了技术对策。塔河油田地层因素对施工泵压的影响主要体现在泵压高、泵压突降、泵压低、砂堵四个方面。从原因机理出发,结合现场井例进行分析,总结出具有塔河油田特色的处理措施。对施工压力异常的进一步认识对塔河油田及其他类似油藏的压裂施工具有重要指导意义。Aiming at the abnormal pressure in acid fracturing of Tahe Oilfield, the paper analyzed and summarized rea- sons causing pressure anomaly from characteristics of construction curves. For effect of formation factors, the technical measure was proposed. The influence of the formation factors on the construction pump pressure in Tahe Oilfield was main- ly presented from four aspects of high pressure pump, pump pressure dump, low pump pressure, and sand plug. Based on the mechanism causing the pressure anomaly, in the combination with well cases, it was summarized that the treatment measures with the characteristics of Tahe Oilfield. The further understanding of pressure anomaly has an important instruc- tion significance for acid fracturing in Tahe Oilfield and other similar reservoirs.
