本文着重论述了用地面非无穷远对称三极剖面法寻找深部高阻油气藏的原理、以及部分水槽模拟实验结果和野外试验结果。理论分析和试验结果表明，该方法不仅能够有效地消除各种地表干扰，而且无须依赖钻井资料，具有效率高、成本低、勘探深度大、对高阻体灵敏度高、能直接圈定油气藏边界范围等优点，不失为一种廉价而高效的油气普查勘探方法。 This paper focuses on the principle of searching for deep high-resistance reservoirs by the terrestrial non-infinity symmetrical triple-polar profile method, as well as the simulation results and the field test results of some sinks. Theoretical analysis and experimental results show that this method not only can effectively eliminate all kinds of surface disturbances but also does not need to rely on drilling data. It has the advantages of high efficiency, low cost, large exploration depth, high sensitivity to high resistivity bodies, direct delineation of reservoir boundary And other advantages, after all, a cheap and efficient oil and gas census exploration methods.
