摘要:
为确定辽河坳陷齐40区块稠油油藏在汽驱开发过程中形成的汽驱优势通道,应用储集层静态描述和开发动态分析相结合的方法,确定了渗透率、有效厚度、沉积微相、变异系数、夹层频率等汽驱优势通道的地质评价参数。根据开发动态特征确定优势通道砂体并提取样本数据,应用灰色关联度分析法确定各参数权重,运用模糊聚类分析法划分2类汽驱优势通道并确定其参数值,由此建立了汽驱优势通道的地质分类与模糊评价标准,进而应用模糊模式识别法评价和预测汽驱优势通道的空间展布。实际应用结果表明,该方法较为客观和准确,可为汽驱开发方案的制定提供依据。
Abstract:
In order to determine preferential steamflooding pathways formed during steam drive production in the heavy oil reservoirs in Block Qi40 of Liaohe depression, the parameters for geological evaluation of preferential pathways such as permeability, effective thickness, sedimentary microfacies, coefficient of variation and interlayer frequency are verified by using a combined method of static reservoir description and development performance analysis. Sandbodies of preferential pathways are determined and sample data are extracted on the basis of development performance characteristics. The weights of each parameter are determined by using grey correlation analysis method and fuzzy clustering analysis method is used to classify the steamflooding preferential pathways into 2 types and to obtain these parameters, based on which the standards of geological classification and evaluation are established for preferential steamflooding pathways and then fuzzy pattern recognition method is used to evaluate and predict the spatial distribution of the pathway. The practical application shows that this method is objective and accurate, which can provide basis for steamflooding development plan making
