在一定的勘探投资前提下,勘探目标的最小经济资源规模指标是地质目标能否取得勘探经济效益的临界点,只有当资源量大于最小经济资源规模时,勘探项目才是可行的。本文通过估算开发投资、储量价值及油气价值等先求出勘探目标最小经济储量规模关系式,然后根据勘探目标的目的层埋深、储量升级系数及油气价格等因素反推最小经济资源规模。
Under the premise of certain exploration and investment, the minimum economic resource scale target of exploration target is the critical point of whether or not the geological target can obtain the exploration economic benefit. Only when the resource amount is larger than the minimum economic resource scale, the exploration project is feasible. In this paper, the minimum economic reserve scale of exploration target is obtained by estimating development investment, reserve value and oil and gas value, and then the minimum economic resource is estimated according to the depth of target layer, reserve upgrade coefficient and oil and gas price.
