摘要
以某实际油藏地质特点、开发动态和理论公式为基础,全面考虑了影响水平井开发效果的7个因素,每个因素含有3个水平数,利用正交实验设计方法设计了18个试验方案,然后采用油藏数值模拟方法建立相对应的油藏数值模型并进行计算。以十年末采出程度为分析指标,利用直观分析方法和方差分析方法得出了底水油藏水平井开发效果影响程度的大小,并用简单比较法进一步验证了结果的准确性。通过以上研究,可以进一步为提高该油藏水平井开发效果提供依据,并为同类油藏提供借鉴。
Based on the geological characteristics, development performance and theoretical formulas of real reservoir, seven elements affecting the horizontal well development effect were deterrmined as test factor, each of which includes 3 factor levels respectively. By means of orthogonal experimental design method, designed eighteen testing protocols and employed reservoir numerical simulation technique establishing and calculating the correspond- ing reservoir model. Then the study concluded that the influential extent of horizontal well on the development effect of the reservoir within bottom water had been obtained through visual analysis and variance analysis methods. Fur- ther, the accuracy of the results was testified by simple comparisons. The above research has provided potent evi- dence for horizontal wells enhancing the reservoir development effect and efficiently guided for the similar reservoir development.
