摘要
为满足特高含水期开发需要,某试验区通过完善现有分层注水工艺技术,缓解平面和层间矛盾,提高薄差油层动用程度。通过在该区块对注水井进行注入剖面同位素测井,指导了细分注水方案的制定;对测井资料进行统计分析,评价了单井和井组细分注水措施的效果及区块油层动用状况,为油田长期水驱开发提供了有力的依据。
To meet the development needs during its ultra-high water cut stage,a test block improved the existing layered water injection technology to alleviate the contradictions on the plane and among layers,and improve the production of thin and poor oil layers.By using isotopic injection profile logging in water injection wells in this block and statistical analysis of logging data,the subdivision water injection schemes are formulated,and the effect of subdivision water injection measures of single well and well group and the oil production status in this block are evaluated,so as to provide a strong basis for long-term water flooding of the block.
