在油气勘探战略规划研究中，需要综合分析不同区带的勘探形势、资源基础、工程技术条件，确立未来一个时期资源接替序列、油气勘探重点和发展目标。通过不同区带勘探现状、勘探潜力进行定量计算，建立了一种勘探战略规划中的资源配置方法。该方法首先建立了包含资源探明程度、探井密度、三维地震覆盖密度等3个关键参数的勘探现状指数公式，对当前的勘探状态进行定量计算；其次建立了勘探潜力定量评价公式，综合纳入了反映勘探状态的阶段探明速度、资源潜力、工程技术适应性等参数；最后将勘探现状指数与勘探潜力指数置于统一评价平台，建立了勘探现状指数和勘探潜力指数交会图版，形成了8个油气资源配置区，按照勘探状态对比定策略、潜力定量评价定目标的思路，确立了一个时期内油气勘探发展重点与勘探部署时序，满足了不同区带间状态明确、潜力定量、技术可行的资源配置需求。该评价方法具有普适性、评价结果具有唯一性的特点。

During petroleum exploration strategic planning and study, it is necessary to comprehensively analyze on exploration status, resource basis and engineering technology conditions of various plays, in order to determine resource replacement sequence, petroleum exploration focus and development targets in the future. According to quantitative calculation on exploration status and potential of different plays, a resource allocation method in exploration strategic planning was established. In this method, an exploration status index formula for three key parameters, namely, resource proven degree, exploration well density and 3D seismic coverage density was firstly constructed for quantitative calculation on current exploration status. Secondly, a quantitative evaluation formula for exploration potential was established and incorporated comprehensively with some parameters like interim proven speed that reflected exploration status, resource potential and engineering technologic adaptability. Finally, exploration status index and potential index were put in unified evaluation platform in order to construct a cross plot for these two indexes, and then eight petroleum resource allocation areas were formed. According to the thinking of the strategy defined by the comparison on exploration status and the target by quantitative potential evaluation, petroleum exploration and development focus and exploration allocation sequence in certain period were determined to meet resource allocation requirement on clear status, quantitative potential and feasible technology for various plays. This evaluation method has the characteristics of universality and unique evaluation result.
