摘　　要：以克拉玛依油田七中区复合驱试验区为例,选取8种本底浓度低的示踪剂对试验区10个井组进行示踪剂监测,应用Eclipse软件对示踪剂产出曲线进行精细拟合与分析。依据示踪剂平均产出率、峰值突破速度、渗透率倍数、示踪剂峰型特征等表征参数把试验区井间水流通道划分为一级优势通道、次级优势通道与正常孔隙通道3种类型,提出一级优势通道用强调,次级优势通道用中调,正常孔隙通道正在发展到次级优势通道的(渗透率倍数接近8)用弱调。根据各井层通道类型与非均质特征,给出了各井组在各小层的调剖强度和调剖剂用量设计的建议。Taking the compound flood test area of District Mid-7 in Karamay oilfield as an example,the tracer monitoring is conducted in 10 well groups in this area by selecting 8 low-concentration tracers,and the curves for these tracers are matched and analyzed finely using Eclipse.Based on the characterized parameters such as mean yield,peak breakthrough velocity,permeability multiple,tracer peak characteristic,etc.,the interwell water flow channel in the test area is divided into primary predominant channel,secondary channel and normal porosity one.It is suggested that for these three channels,strong,medium and weak profile controls are applied respectively,among which when the permeability multiple is close to 8,the weak profile control is made for the normal porosity channel.In addition,this paper presents the suggestions for profile control intensity and profile control agent requirements for each layer corresponding to each well group,according to the channel types and heterogeneous features in this area.
