印尼W油田在生产开发中面临的问题及技术对策

Problems and Technical Countermeasures of Production for W Oilfield in Indonesia

印度尼西亚W油田在生产开发中主要存在储层主力油层含水高、层间差异大、油藏温度高、生产井结垢风险高等问题,导致油田水驱开发效果差、生产井运行时率低。针对上述问题,采用分层注水、机械堵水技术,解决了主力油层含水高和层间差异大的问题;采用物理防垢和化学清防垢相结合的方法,解决了生产井结垢问题,提高了油田的整体开发效果。

In the production and development of Indonesia W oilfield,there are many problems,such as high water content,large difference between layers,high reservoir temperature and high risk of scaling in production wells,resulting in poor water flooding development effect and low operation time of production wells.In view of the above problems using separate layer water injection,mechanical water plugging and solve the problem of the main reservoirs in high water cut and layer difference,using physical anti scaling and chemical anti scaling method to solve the scaling problem of production wells,so as to improve the development effect of oilfield.
