摘要
目前M油田面临含水率不断升高、产油量降低的问题,需对油田实施动态监测并进行生产措施调整。生产动态测井资料能够对油井产出层位、流体性质进行识别并计算产量,其解释结果对井筒生产状况认识和开发措施调整至关重要。由于生产动态测井曲线质量受管柱条件、施工状况、流体类型等多方面因素的影响,其解释结果的精度往往较低,影响现场决策。重点研究了复杂管柱条件下生产动态测井资料的精细解释方法,将生产动态测井所提供的产出剖面和注入剖面应用于产水层位识别、封堵作业以及注水方案制定。实际应用表明,生产动态测井在M油田动态监测、增油上产中应用效果良好。
M-oilfield is facing the problems of increasing water cut and decreasing oil production.It is imperative to carry out dynamic monitoring and adjust production measures for oilfields.Production Logging Test(PLT)can identify the production layers,fluid properties and calculate production of oil wells,and its interpretation results are very important for the understanding of wellbore production status and the adjustment of development measures.Because the quality of PLT curve is affected by many factors,such as string conditions,construction status,fluid types,etc.,the accuracy of interpretation results is low,which affects the rationality of on-site decision-making.This study focuses on the precise interpretation method of PLT data under the condition of complex production string.The production profile and injection profile provided by production performance logging are applied to the identification of water yield formation,plugging operation and formulation of water injection scheme.The actual production data shows that the application effect of PLT data in dynamic monitoring and oil production increasing in M-oilfield is good.
