摘　　要：为探索寻找复杂类型油气藏富集区的方法 ,以松辽盆地北部的西部地区为例 ,列举来 36井区、古龙—茂兴地区和古 81井区的勘探实例 ,运用常规化探、放射性热释光和测氡等技术 ,结合该区已有的钻井、地质和物探资料进行综合分析 ,对该区岩性和地层油气藏富集区带进行了预测和评价。同时 ,利用油气化探新方法预测了油气产层的深度 ,实际效果与预测结果吻合较好。在此基础上 ,总结了利用油气化探技术在勘探具有多套油气组合、含油错叠连片地区寻找复杂类型油气藏的低成本、高效益方法 ;给出了对于勘探复杂类型油气藏时应遵循的正确方法和勘探程序 ;表明将油气化探常规技术方法与新技术、新方法相结合 。The paper takes the western region of northern Songliao Basin as an example, prospects and evaluates oil gas concentration areas(zones) of both lithology and strata by using the techniques and methods of conventional geochemical exploration, radioactive thermoluminescence and Rn measuring etc., and combining with the drilling, geological and geophysical data of Songliao Basin on the basis of listing exploration cases of Lai36 well, Gulong Maoxing region and Gu81 well, in order to seek the prospecting methods of oil gas concentration areas of complicated types. In the same time, the depth of oil gas reservoir is prospected by using the new methods of oil gas geochemical exploration whose prospecting results are identical with the practical effects. On the basis of all the above, the paper summarizes the methods of both the lower cost and higher benefit for seeking oil gas accumulation of complicated types by using oil and gas geochemical exploration techniques in exploration areas of several oil gas combinations and oil gas interlocking joins; and gives the correct methods and exploration procedures which should be adhered to explore oil gas accumulations of complicated types; and confirms that the conventional techniques and methods of oil gas geochemical exploration can be still play the important rein to explore higher level exploration areas by integrating with the new techniques and methods.
