摘要(Abstract)：

针对特低渗油藏水平井开发特点,引入注水见效周期、水平段产液率新的评价指标,确定了水平井网注水开发效果的9个评价指标。基于直井与水平井开发的动态差异性以及特低渗油藏与常规油藏开发的不同点,采用类比分析、水平井等效评价、虚拟开发等综合方法,初步给出了鄂尔多斯盆地特低渗透油藏水平井开发分类评价指标。考虑各因素之间的等价、因果、过程等关系,根据层次分析法,确定了评价指标的权重关系。采用模糊数学法,构建了水平井开发的综合评价体系。实际油田应用效果表明新体系评价结果可靠。
In the light of the developed characteristics of the horizontal well in ultra-low permeability oil reservoirs,the new evaluating indexes such as injected water effective cycle and horizontal-interval produced liquid ratio are proposed,and nine evaluating indexes for the water developed effects of the horizontal well pattern were determined. On the basis of the dynamic differences between the developments of the vertical and horizontal wells and varieties between the ultra-low permeability and traditional oil reservoirs,with the help of the comprehensive meth-ods including analogy analysis,equivalent evaluation of the horizontal well,virtual development and so on,the classifying and evaluating indexes were preliminarily presented for the horizontal well development in the ultra-low permeability oil reservoirs of Ordos Basin. Considering the relationships(e. g. equivalence,cause-consequence,process etc.) among different factors and analytic hierarchy process(AHP),the weighting relationships were determined for the evaluating indexes. By means of the fuzzy mathematics,the comprehensive evaluating system of horizontal well development was developed. The field application results show that the achievements of the new evaluating system are reliable.
