测井资料在压裂规模预测中的应用

压裂是低孔、低渗油田改造的主要增产措施。镇泾油田是典型的＂三低＂储层,产油井都需要压裂求产。通过对镇泾油田常规测井资料、岩石物理分析及试油数据的研究分析,确定了区块的储层评价标准,按油藏驱动类型进行分类,有针对性地为压裂层位的优选提供参数依据。根据压裂规模与储层厚度、储层类型、油藏类型、油气级别等的关系,对镇泾油田压裂规模进行预测评价,为压裂措施提供准确有效的层位及压裂规模建议,尽快获得工业油流。

Application of Logging Data in Fracturing Forecast

Fracturing is a major stimulation to transform low porosity and low permeability oil field.Zhenjing oilfield is a typical reservoir with low porosity,permeability and oil saturation,so all the producing wells need fracturing to get oil-producing.Based on the analysis of the conventional logging data,petrophysical analysis and well testing results of Zhenjing field,this paper determined the block reservoir evaluation standard,classified the layers according to the reservoir type so as to provide parameter criteria for the preference selection of the fracturing layer.According to the relationship between the fracture scale and reservoir thickness,reservoir type,oil reservoir type,hydrocarbon level,etc,this paper also has made prediction and evaluation of the scale of fracture in Zhenjing field and provided accurate and effective horizon information and fracturing scale for the fracture measures to get industrial oil-flows quickly.
