油田老区经过多年的勘探开发,探明的优质储量均已动用。新增探明储量区块品位逐年变差,在低油价下难以实现经济有效开发,严重影响油田的持续发展。如何确保存量提效是油田生存和发展的根本,因此做好存量效益分析,探索提高存量效益经济技术对策尤为重要。盈亏平衡法评定产量原理油田评价存量经济效益的关键在于确定油井在不同成本层面 Old oilfield after years of exploration and development, proven high-quality reserves have been used. New proven reserves block grade deteriorate year by year, at low oil prices is difficult to achieve economic and effective development, seriously affecting the sustainable development of the oil field. How to ensure the efficiency of the stock is fundamental to the survival and development of the oilfield. Therefore, it is particularly important to analyze the stock benefits and explore the economic and technological countermeasures to improve the stock returns. Break-even method to assess yield principle The key to evaluating the economic benefits of an oil field lies in determining the cost of a well at different cost levels
