本文在非无穷远三极剖面法的基础上 ,提出了 A对称复合四极剖面法。文中通过大量水槽模拟实验 ,着重论述了 A对称复合四极剖面法异常曲线极值点相对油气藏边界的偏移规律及其机理 ,并提出了准确确定油层边界位置的相应办法。相对非无穷远三极剖面法 ,该方法可提高效率 ,降低成本 ;进一步改善资料质量 ,有利于提高解释精度 ;还可能使野外观测数据的处理计算大大简化 ,有利于及时指导野外生产
Based on the non-infinity triode profile method, this paper proposes A symmetric compound quadrupole profile method. In this paper, a large number of tank simulation experiments are carried out, focusing on the excursion rule and mechanism of the extreme point of the A symmetrical compound quadrupole profile relative to the reservoir boundary and the corresponding method for accurately determining the boundary position of the reservoir. Compared with the non-infinity triode profile method, the method can improve the efficiency and reduce the cost; further improve the data quality, which is beneficial to improve the interpretation precision; and also simplify the processing calculation of the field observation data, which is beneficial to timely guide the field production
