喇嘛甸油田厚油层内液量劈分方法研究

Splitting method of fluid volume within thick oil layers in Lamadian Oilfield

喇嘛甸油田储层发育以厚层为主,层内动用状况差异大,科学合理的动态数据细分方法是改善喇嘛甸油田厚油层动用状况的技术关键。本文在油水井沉积单元液量劈分的基础上,结合监测资料、岩心资料及水淹资料,通过各参数与液量的相关性回归计算得到厚层内液量劈分校正系数,最终实现喇嘛甸油田厚油层内不同部位液量的精确劈分。该液量劈分方法结果合理可靠,能够有效指导喇嘛甸油田厚油层后续精细挖潜调整措施的实施。

Producing status is quite different within thick oil layers mainly developed in lamadian oilfield,reasonable and accurate splitting method of dynamic data is the key technology to improve producing status of thick oil layers in lamadian oilfield.Based on the splitting of fluid volume in oil and water wells,adjustment coefficient could be obtained from the regression and relevance between the fluid amount and parameters combined with reservoir monitoring data,core data and flooding information,so as to realize the fluid amount splitting in different parts of thick oil layers in lamadian oilfield.The splitting method of fluid volume is accurate,reasonable and reli-able,so it can effectively improve the accuracy of the results of numerical simulation and guidance fine tapping thick oil layers in lamadian oilfield.
