摘要
有效控制药剂成本对提升大牛地气田单井经济效益具有重要意义。针对目前大牛地气田药剂成本控制对象不明晰、单井药剂加注量无经济边界等问题,构建大牛地气田单井"三线四区"经济效益评价模型,通过把单位气量的运行成本、操作成本、完全成本"三线"与税后气价进行对比,将单井划分到盈利高效、运行低效、边际有效、运行无效"四区",实现了单井效益分级,明确了成本控制对象。同时,利用盈亏平衡法求取边际区——无效区、低效区——边际区、高效区——低效区的药剂加注经济边界值,为实际生产中较为经济地加注甲醇与泡排剂提供了依据。此法在生产中有效地控制了单井药剂成本,提升了气井的经济效益。
Effective control of the chemical costs will significantly promote single well economic returns in Daniudi Gas Field. To solve the current problems like unclear cost control subject and lack of economic margin of single well chemical injection, we establish an evaluation model of the single well economic returns. And by comparing the running cost, the operation cost and the total cost of gas production volume with after-tax gas price, we divide single well production into four stages： operation with high return, operation with low ream, operation with marginal profit, and operation with no return, and thus clearly define the subjects of cost control. Then through break-even analysis, we calculate the boundary value of chemical injection at different production stages, which provides reference for methanol and foam scrubbing agent in production. Application of the calculation can effectively control single well chemical cost and therefore promote the economic returns .
