摘要:
递减曲线分析方法是预测油田未来生产动态的十分重要的方法。为丰富产量预测方法,在Fetkovich方法研究的基础上,结合产能方程及物质平衡方程的两种表达形式,进一步扩展了产量-时间方程,推导出适用于溶解气驱油藏产量递减的累产-时间方程和累产-产量方程,并在此基础上对S油田H区块进行了矿场应用。用推导方程预测的累产油分别为38.67×104 m3和38.59×104 m3,实际累产为38.91×104 m3,误差控制在1%左右。应用结果表明,对于溶解气驱油藏,采用推导的溶解气驱油藏Fetkovich新方法进行产量递减规律预测是可行的。
Abstract:
Decline curve analysis is a very important method to predict the future production performance of oilfield. To enrich the production prediction,based on the research of Fetkovich method and combining the two expression forms of production formula and material balance equation, two types of production - output equation applicable to dissolved gas drive reservoirs are further derived.Field application of block H in S Oilfield has been carried out. The two expressions predicted the cumulative oil production of 38.67×104 m3 and 38.59×104 m3 respectively, and the actual cumulative oil production is 38.91×104 m3, with the error controlled at about 1%. The results show that for dissolved gas drive reservoir, it is applicable to use the improved Fetkovich method to predict the production decline.
