| 摘 要： | 研究了童宪章院士“7.5B”的准确性和适应性,指出了“7.5B”方法只适用于多个油田的统计计算,而不完全适应于单一油藏。从理论上推导了“7.5B’’的数学表达式,给出了一条准确计算该值的有效途径。对童氏水油比与采出程度关系乙型水驱法及采出程度与含水关系图版作了改进。

| Abstract: | The adaptability and veracity of 7. 5B in Tong Xian-zhang' s formula was discussed and this formula could not be applied to a single reservoir but to a whole oilfield. Theoretic expression of 7. 5B was deduced and a useful precise method to calculate this parameter was put forward. At the same time, this paper makes some modification on Mr. Tongs wateroil ratio va.recovery formula and recovery vs. water cut curve. Also it ex-plains the importance of.these modifications. |
