中文摘要：
基于空间源直接探矿仪探测地下油气资源的基本原理，建立了地层岩性解释模型，剖析了各种岩石的岩性探测曲线特征，探讨了根据地下不同深度岩性综合能量值判别地下岩层性质和位置的方法。研究区3口井的实例验证结果表明，地下油气储层探测符合率总体达到78．5％，证明了该模型的正确性和有效性。最后，就地层倾角对地下油气资源探测误差的影响进行了理论分析，结果表明，地层倾角为30°时，地下油气储层探测误差接近30％～40％．由此说明，探测层段平均地层倾角为26．3°是造成探测误差的主要原因。
英文摘要：
Based on the basic principle of detecting underground oil and gas resources with the direct detecter of the space source, the interpretative models of the stratal lithology were established, and the characteristic curves of lithological detection of rocks were analyzed. And the method of distinguishing the positions and characters of underground rock strata were studied according to the comprehensive energy value of the underground lithology at the different depth. The results of three solid examples verification show that the detection precision of this method attained 78.5 % overall in research area, and also the correctness and effectiveness of the model were proved. Finally, the effect of stratigraphic dip on the detection error of underground oil and gas resources was analyzed in theory, and the results show that it closed with 30% to 40% at 30°. Thus, it is the chief reason of the detection error that the average stratigraphic dip of the detection sections of verification wells comes up to 26.3°.
