A对称复合四极剖面法实验与研究

Test and study of an A-type symmetric complex four-electrode profiling.

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 。

Based on non infinite three pole profiling,the paper proposed an A type symmetric complex fourelectrode profiling.The law and mechanism deviatingextreme point abnormal curves of A typesymmetric complex four electrode profiling from boundary of oil and gas accumulation have been emphatically discussed by vast amount of modeling test in water tank and the relevant methods that can exactly define the boundary position of oil layer have been proposed.Compared with non infinite three pole profiling,the method can raise efficiency,decrease cost,further imrove data quality,so be favorable to improve interpretation resolution;greatly simplify the processing calculation of observing field data,so be favorable to guide field production.
