摘要:

结合油气藏勘探开发实践,对油气藏最小商业储量规模的含义及界定方法进行了较全面的诠释,解释了油气藏最小商业可采储量、最小商业探明储量及最小商业资源量等不同的内涵。通过对不同区域油藏开发规律和产量变化模式的研究,结合投入、产出分析原理,建立了基于油气藏开发概念设计计算最小商业储量规模的通用方法。方法原理主要通过构建油气藏开发概念设计参数与现金流入、流出参数模型的关系,推导了油气藏储量规模与净现值线性关系模型,从理论上揭示了普遍意义上油气藏最小商业储量规模在不同经济条件下的变化特征。该方法可直接应用油气藏勘探开发经济参数、储量品位参数及开发概念方案参数快速评价不同界定条件下的最小商业储量规模,从而为不同油气区勘探项目经济效益排序、探明储量动用潜力目标排序以及油田开发油气藏评价项目和新区产能建设目标论证提供高效技术支撑。

Abstract:

Based on reservoir exploration and development practices, this paper defines the minimum commercial reserves of petroleum reservoirs and explains the specific connotations of the minimum commercial recoverable reserves, the minimum business proved reserves and the minimum business resources of reservoirs.By studying the development regularities and production change patterns of reservoirs in different regions and in combination with the principles of input-output analysis, a universal method was presented for calculating the minimum commercial reserves based on the reservoir development conceptual design.The relationship among reservoir development concept design parameters and cash inflow and outflow parameter models was established first and then used to build a linear correlation model of reservoir reserves to net present value.For a given reservoir, this model theoretically revealed the characteristics of variation of the minimum commercial reserves under different economic conditions.The method can rapidly evaluate the minimum commercial reserves under different boundary conditions by directly using the economic parameters of reservoir exploration and development, the parameters of reserves grade and the parameters of the development concept plan.Therefore, it can provide efficient technical supports to the economic benefits ranking of exploration projects in different oil fields, the ranking of potential targets of producing proven reserves, and the demonstration of reservoir evaluation projects during oilfield development and production capacity building goals in new blocks.

Key words: cash flow model, minimum commercial reserves, design of development concept, reservoir development
