| 摘 要： | 对于遮挡层(隔层)较差的低渗透储层，采用人工隔层控制压裂缝高非常必要。分析了影响人工隔层阻抗的因素，对岩芯流动装置进行了改造。用Malvern激光粒度测试了一种上浮剂的粒度分布，对岩芯进行沿轴向剖分2/3的特殊处理，通过岩芯流动实验来模拟人工隔层的形成。按正交设计原理设计实验方案，并按照岩芯流动实验行业标准进行实验。应用非线性处理后的逐步回归方法得到了人工隔层强度与携带液黏度、上浮剂浓度和岩芯渗透率的统计公式。为指导现场控制缝高的压裂设计提供了依据。

| Abstract: | It is necessary for low-permeability formation with weak barriers to control fracture height hydraulically by creating artificial barriers.In this paper，influential factors on resistance role of artificial barriers are analysized.Then，the core flow test device is modified by affixing an intermediate container in order to keep the buoyant dispersing during experiment.The particle size distribution is tested with Malvern laser counter.The crack is made about 2/3 length in artificial core for simulating artificial barrier process by core flow test which is accomplished based on recommended practice of petroleum industry.Lastly，successive regression method is applied and a statistical relationship of the barrier strength with carrying fluid viscosity，buoyant diverter concentration and core permeability obtained.The results provide a design foundation for controlling the fracture height growth. |
