某盆地油气勘查成本预算和风险分析

某高原盆地的油气资源量较为丰富，可找到大型油气田。根据含油气盆地地质构造特征、生油岩的厚度与热演化程度、储集层和区域性盖层的发育情况等因素，确定了两个含油气远景区，拟作为重点找油气靶区。提出了两个可供选择的油气勘探布署方案。在此基础上，选用适当的成本预算基本参数，进行油气勘查成本估算，并对两个方案进行了优选对比与具体的风险分析，提出方案决策意见。

COST BUDGET AND RISK ANALYSIS OF OIL AND GAS EXPLORATION OF A CERTAIN BASIN

The quantity of oil and gas resources in a certain plateau is abundant and it is likely that large oil and gas fields may be found in the plateau basin.Based on the characteristics of the geological structures of OGB,the thickness of oil source rocks,the degree of heat evolution,the upgrowth of reservoirs and regional covers and so on,two oil and gas-bearing prospect areas have been considered as the critical targets of oil and gas exploration.Accordingly two alternative schemes of oil exploration have been proposed.Cost budgets of oil and gas exploration have been proposed on the basis of selecting some economic indicators and some cost budget basic parameters,Of the two cost budgets,the better one has been selected and the risk analysis has been carried out.
