摘要
如何科学评价油气区块、做到区块有序进退是矿权工作的重点。以前的区块评价是将不同勘探程度区块放在同一平台进行评价,评价结果具有局限性,而利用风险概率法评价油气区块可以得到比较科学的结果。根据区块勘探程度不同对区块进行等级划分,计算区块勘探指数;对不同勘探程度区块采用不同油气地质评价参数,利用风险概率法计算其含油气概率;根据资源评价结果对油气区块勘探价值进行评价;最后根据勘探指数、含油气概率、勘探价值采用专家意见法进行综合优选排队,给出油气区块评价结果,为勘探部署决策提供参考。
How to scientifically evaluate the oil and gas block and achieve the block orderly advance and retreat is the key point of the mining rights work.The previous block evaluation was to put blocks with different exploration levels on the same platform for evaluation,and the evaluation results were limited,while the evaluation of oil and gas blocks by using the risk probability method could obtain scientific results.According to different exploration degrees,the blocks are classified to calculate the exploration degree index.Different oil and gas geological evaluation parameters are used for the blocks with different exploration degrees.The exploration value of oil and gas blocks is evaluated according to the results of resource evaluation.Finally,according to exploration degree index,probability of containing oil and gas and exploration value,the expert opinion method is adopted to conduct comprehensive optimization and queuing,and then the evaluation results of oil and gas blocks are given,which can provide a good reference for exploration deployment decision.
