摘要
埕岛油田是河流相疏松砂岩油藏,初期采用温和注水政策,压力降低、液量下降等开发矛盾逐步暴露。为实现海上油田的高速高效开发,通过油藏数值模拟计算和分析,提高注采比可有效提高水驱效果,提高采油速度,实现高速高效开发。2005年7月井区开始提注,提注后对应受效油井出现明显增油效果,液量不断上升,开发形势明显好转。
Abstract
Chengdao Oilfield is a fluvial face unconsolidated sand reservoir, and sand pressure dropdown, mass production depression and some other development contradictions reveals gradually because of the rate, and develop the reservoir effectively. After increasing water injection rate in pra the production of offset producer improves, the mass production improves step development status improves apparently. ctice in July, 2005, by step, and the
