在油田开发过程中,单井控制可采储量是新井价值的直接体现,是决定打新井是否经济可行的基础,新区开发和老区调整都需要打新井,这就决定了定量研究单井控制可采储量影响因素的重要性。本文筛选出了影响中高渗水驱油藏单井控制可采储量的主要影响因素,通过正交试验设计,建立了单井可采储量多因素分析样本,然后在此样本的基础上,采用多因素方差分析方法分析了多因素同时变化时,各因素以及交互作用对单井可采储量的影响程度研究。采用标准回归系数法,得出了多因素影响下各因素对单井可采储量的影响权重。
In the process of oilfield development, the recoverable reserve of single well control is the direct embodiment of the value of new wells and the basis for determining whether new wells are economically feasible. The development of new areas and the adjustment of old areas require new wells to be drilled, which determines the recoverable amount of single well control The importance of reserves influencing factors. This paper screened out the main influencing factors of single well control recoverable reserves in medium and high permeability waterflooding reservoirs. Through the orthogonal experimental design, a single well recoverable reserves multivariate analysis sample was established. Based on this sample, Analysis of variance analysis of multiple factors simultaneously changes, the factors and the interaction of single well recoverable reserves of degree of impact. Using the standard regression coefficient method, the influence weight of each factor on single recoverable reserves under the influence of multiple factors was obtained.
