摘要:
童氏图版法预测采收率广泛应用于水驱油田的生产实践中,但该方法对高含水油藏井网调整后目标区块采收率预测的契合性较差。文中根据地质储量与甲型水驱规律曲线斜率的关系,计算了童氏图版系数X的值;基于改进的甲型水驱规律曲线,引入无水采收率和水驱规律曲线积分常量,推导出了适用于高含水油藏井网调整后的改进童氏图版公式,并绘制了改进童氏图版。将改进的童氏图版应用于大庆油田葡北三区采收率的预测,适用的X为5.513 691 47,预测的采收率为45%,预测误差小于0.5%。改进的童式图版应用于高含水油藏井网调整后区块采收率的预测,具有较高的精度,对高含水油藏生产开发具有一定的指导意义。
Abstract:
Tong′s chart method is widely used in the production practice of water flooding oilfields, but the prediction of oil recovery in target blocks of high water?鄄cut reservoirs after well-pattern adjustment is not well matched. According to the relationship between geological reserves and slope of type-A water drive curve, the value of coefficient X is calculated. Based on the improved type-A water drive curve, the integral constant of waterless recovery rate and water drive curve is introduced. The improved Tong′s chart formula suitable for well pattern adjustment in high water cut reservoirs is derived, and the improved Tong′s chart is formulated. The application constant X is 5.513 691 47, the predicted recovery is 45%, and the predicted error is less than 0.5%. The results show that the improved Tong′s chart has high accuracy in predicting the block recovery after well pattern adjustment in high water-cut reservoirs, and has certain guiding significance for guiding the production and development of high water-cut reservoirs.
