摘要： 针对柴达木盆地生物气藏形成的特殊地质条件,以地质类比法为主,辅以圈闭地质分析法和盆地模拟法对柴达木盆地生物气资源潜力进行了分析，最终以蒙特卡罗法确定出柴达木盆地生物气总资源量为14755x10*m2.在此基础.上,结合地质分析，利用PASYS盆地评价系统评价盆地及区带(块)的生物气资源潜力,确定出近期盆地生物气勘探的有利领域为北斜坡和中央凹陷，并提出了相应的有利勘探目标。同时,根据目前生物气勘探认识程度,指出今后盆地生物气勘探的主要目标为寻找潜伏构造圈闭和非构造圈闭气藏。

Abstract: Based on the particular geological conditions of forming biogenetic gas reservoir in Qaidam basin, it is calculated from Monte Carlo method that the total resource amount of biogenetic gas is 14755x108m3, integrated with the results obtained from trap geological analysis and basin modeling method. A lso, petroleum assessment system (PASYS) is adopted to evaluate the resource potential of this basin and plays/blocks, and the favorable areas for biogenetic gas prospecting in the near future are Beipo (northern slope) and the Central Depression with corresponding exploration targets, of which the buried structural trap and non -structural trap are the main concern in Qaidam basin.

Key words: Qaidam basin, biogenetic gas, resource, evaluation, exploration potential
