摘要(Abstract):
喇嘛甸油田自投产开发以来,从产量规模上可划分为上产、稳产和递减3个阶段。进入特高含水期后,随着油田水驱开发难度不断加大,产量递减规律也变得越来越复杂。为有效保证水驱产量规模和油田开发效果,通过对影响水驱产量递减的主要因素进行研究,利用3种产量递减曲线方程,结合水驱各层系实际生产数据,确定了产量递减类型,预测了未来产油量,提出了减缓产量递减的注采调整措施。
Since Lamadian Oilfield put into production,three stages are classified in the production scales i.e.production increase,stablization and decline.After entering the late period of extra-high water cut,with the gradual increase of the water-flooded oilfield development difficulties,the production decline laws are becoming more and more complex.In order to effectively ensure the production scale of the water flooding and the development effects of the oil field,the types of the production decline are determined by the studies of the main factors influencing the decline and with the help of three kinds of curve equation about the production decline,and furthermore by integrating the actual production data of each waterflooded layer.In addition,the future oil production is also predicted and the adjusting contermeasures in the injection and production are presented to lower down the production decline.
