【摘要】：XJ油田进入含水期和高含水开发期后,随着开采程度的加深,地下油水关系、剩余油分布越来越复杂,非均质更加严重,开发难度也来越大,需要探索新的开发方式和开发思路。油田进入含水期和高含水期开采后,含水量增加,水油比上升,增加了产出液处理的难度和成本,单位操作成本也随之增长。在油气开采中,井下作业费、稠油热采费、油气处理费用、措施费用、地面设施维护费用等过程成本也大幅度的上升。论文以XJ油田为研究对象,收集油田开发数据、成本数据和外部数据等相关资料。以操作成本构成及归集为切入点,运用管理学、经济学、数学、统计学、会计学等相关学科的知识,对XJ油田开发项目操作成本总的变动趋势,按产品类型、油藏类型、不同井深、不同含水率、成本习性等方面对操作成本变动趋势进行较为系统的分析；采用指数分析的方法,对操作成本的构成项目的变动进行分析,采用复合分组的方法,从不同的角度和层次对操作成本变动原因进行了分析。采用洛伦兹曲线和基尼系数分析方法,对XJ油田操作成本的不均衡性进行分析。通过计算基尼系数,得到操作成本的不均衡程度指标,以便在编制操作本计划时,考虑油田操作成本的不均衡性,合理安排油田的操作成本,提高油田开发效益。
[Abstract]:After XJ oilfield enters water cut period and high water cut development stage, with the deepening of exploitation degree, the distribution of remaining oil is more and more complex, the heterogeneity is more serious, and the development difficulty is more and more serious. Need to explore new development methods and development ideas. After the oilfield enters the water cut period and the high water cut stage, the water content increases and the water-oil ratio increases, which increases the difficulty and cost of the production liquid treatment, and the unit operation cost also increases. In oil and gas production, the process cost such as underground operation fee, heavy oil heat recovery fee, oil and gas treatment cost, measure cost, surface facility maintenance cost, etc. Taking XJ oilfield as the research object, this paper collects the development data, cost data and external data. By using the knowledge of management, economics, mathematics, statistics, accounting and other related disciplines, the general changing trend of operating cost of XJ oilfield development project is analyzed according to the product type and reservoir type, taking the operating cost composition and aggregation as the starting point, using the knowledge of management, economics, mathematics, statistics, accounting and so on. The variation trend of operation cost is analyzed systematically in different well depth, different water cut, cost habit and so on. The method of index analysis is used to analyze the change of operation cost items, and the method of compound grouping is used. The reason of operation cost change is analyzed from different angles and levels. By using Lorentz curve and Gini coefficient analysis method, the unbalance of operating cost in XJ oilfield is analyzed. By calculating Gini coefficient, the unbalanced degree index of operation cost can be obtained, in order to consider the imbalance of operation cost in oil field, reasonably arrange the operation cost of oil field, and improve the benefit of oilfield development.
