摘要
根据水平井泄油椭球体理论,认为水平井控制的体积是被油层顶、底界面截得的椭球圆台的体积.该体积中含有油气的量即为水平井的地质储量,进而推导出容积法计算水平井地质储量的理论公式.利用该公式对中2-平25井地质储量进行了计算,其计算精度较高,误差为6.8%,可以在生产中推广应用.
In the paper, according to the theory of oil drainage ellipsoid in horizontal wells, the control-volume of horizontal wells was the volume of ellipsoidal truncated cone that was truncated by the top interface and bottom interface of the oil layer, and the geological reserve of horizontal wells is the weight of oil and gas in the control-volume. The theoretical formula of the geological reserve of horizontal wells in volumetric method is deduced according to the theory, and the geological reserve of 2-P25 Well was calculated by the formula and the result shows that a high precision difference is 6.8%. The method can be widely used in oil production.
