摘要
海上油田由于开发井数少，采用大井距和多层合采的开发方式，具有生产井段长，储层物性。流体性质随深度变化大的特点，层间非均质性严重，在生产动态上反映层间干扰程度大。通过定量表征层间矛盾的因素计算层间干扰系数的大小，从而判断层间干扰程度的强弱。现场应用结果表明，该方法计算的层间干扰系数与实际测试的层间干扰系数极为接近。
Due to the less producers in an offshore oilfield, the adopted long-distance well spacing and multiple- layer commingled production are characterized by long producing interval, huge changes of physical and fluid prop- erties with the depth, rather serious interbed heterogeneity and such a high responded interference degree in pro- duction performances. Therefore by virtue of the quantitatively characterizing the influencing factors of interbed contradiction, the size of the interbed interference coefficients can be calculated, thus the degree of the interval in- terference can be judged. The results of the oilfield application show that the calculated interbed interference coeffi- cients are extremely close to those of the actually tested.
