摘要
青168井区的长3油藏从1996年开始试采,2003年投入全面开发。历经自然能量的开采,这一阶段地层压力下降快,油田能量供给不足,老井递减幅度大。但由于新井的不断投产,该阶段产油量呈上升趋势,含水略有下降。根据对油井产能状况、油井含水状况、地层能量状况等生产形势分析,找出影响稳产的主要因素,为油区后续开发提供有力保障。
Production test of Chang3 reservoir in Qing 168 wellblock started in 1996; the reservoir was put into comprehensive development in 2003. It experienced natural depletion and water flooding development two stages. During natural energy development in November 2008 to September 2009, the formation pressure dropped quickly, oil field energy supply was insufficient, old well productivity declined quickly. But due to the continuous production of new wells, total oil production in the stage ofoil production was an upward trend, water cut was slightly down. In this paper, based on oil well productivity condition, water cut condition and formation energy condition, main factors to affect the stable production were determined, which could provide strong guarantee for follow-up development of the oil region.
