近年来,盈亏平衡分析在油田开发项目中得到了广泛应用。在进行油田储量经济评价的同时,应做到使每一个新投产的油田从一开始就有经济产量,并且是保证以后各项决策符合经济效益的前提。动态盈亏平衡分析就是将项目盈亏平衡状态定义为净现值等于零的状态。根据动态盈亏平衡分析的原理,建立了油田初始经济产量的数学模型,推导出了油田初始产油量的经济边界值的计算公式。若油田的初始产量大于经济边界值,则表明该区域的开发具有经济价值,在目前的经济技术条件下可以投入开发;如果油田的初始产量小于经济边界值,则表明该区块在目前的各项条件下不具有开发价值,这一开发活动即为无效益甚至亏损的,可以暂时不投入开发,等待以后技术进步、经济许可时再考虑投入开发。以某油田为例验证了该公式的应用过程。
In recent years, breakeven analysis has been widely used in oilfield development projects. While carrying out the economic evaluation of oilfield reserves, it is necessary to make every newly-started oilfield have economic output from the very beginning and be a prerequisite for ensuring that all future decisions are in line with economic benefits. Dynamic breakeven analysis is defined as the state of the project breakeven net present value is equal to zero state. According to the principle of dynamic breakeven analysis, the mathematical model of the initial economic output of oilfield is established, and the formula for calculating the economic boundary value of initial oilfield production is deduced. If the initial output of the oilfield is greater than the economic boundary value, it indicates that the development in this area has economic value and can be exploited under the current economic and technological conditions. If the initial output of the oilfield is less than the economic boundary value, This condition does not have the value of development. This development activity is ineffective or even loss-making. It can be temporarily not invested in development and is awaiting technological progress in the future. Economic development should be considered in economic development. Taking an oilfield as an example, the application of this formula is verified.
