油水井降压对两个剖面影响的认识

The Influence In Two Profiles Caused By The Corresponding Pressure-reduction Of Oil-water Well

油井通过采取加深泵挂、调大参数、换大泵径及检泵等放大生产压差措施,降低油井流压和水井端注水压力,减小层间矛盾和平面矛盾,挖掘油层潜力,提高可采储量,64口油井平均单井日增油0.7t,综合含水下降0.2个百分点,平均流压下降1.1MPa。并通过理论研究和数据统计分析,得出对两个剖面影响的规律,为今后指导油水井降压奠定了技术基础。

By stimulation of deeping pump setting depth、changing bigger pumping parameters、changing larger pump or enhancing the output pressure difference,we had reduced the flowing pressure of oil well and the injection pressure of water well,decreased the conflicts between layers and that between oil and water well,maximized the formation output protential and improved the recoverable reserves.By these ways,the average daily oil output of 64 oil wells increased 0.7 tons,integral water cut decreased 0.2 percent,average flowing pressure droped 0.1 million pa.Through the theoretical research and data statistical analysis,we obtained two profile influence rules and paved the way for the future pressure-reduction technology of corresponding oil-water wells.
