摘要(Abstract)：

喇嘛甸油田二类油层聚驱开发期间,对油井进行压裂是保障聚驱效果的有效方法之一,可减少低效、无效措施井,增加油井经济效益。以影响压裂效果的主要因素为变量,以压裂措施无效时总累计增油量为评价指标,利用多元回归分析原理,建立了压裂效果预测方程。在二类油层聚驱中验证表明,压裂效果预测方程的预测精度可达到90.5%,能够满足油田生产需要,保障了聚驱优势发挥。
During the development of the secondary oil reservoirs by polymer flooding in Lamadian Oilfield,the producers' fracturing is one of the effective ways to ensure the effects of the polymer flooding,for the method can reduce those low-effectiveness and ineffective stimulated wells,and furthermore increase the economic benefit.Taking the main influencing factors of fractured effects as variable,and moreover regarding the total accumulated oil increased production as evaluating index when the fracturing is ineffective,the predicting formula of the fractured effects is established with the help of multiple regression analysis principle.The test of the above flooding shows that the forecast accuracy of the formula is up to 90.5%,thus the achievement stated above can meet the requirements of the oilfield production and ensure the fully use of the polymer flooding.
