油水井联动配套工艺效果分析及认识

Effect Analysis and Understanding of Oil-Water Well Linkage Matching Process

奈曼区块自分层系开发以来由于注采井网不完善、水淹水窜等问题导致自然递减率偏高。针对区块生产矛盾,需要积极转变观念,以区块稳产为出发点,以油水井措施为手段,加强油水井联动,在推进精细注水、水井深部调剖工艺的同时,配合实施油井找堵水、捞封、钻塞回采等低成本配套工艺,以实现措施挖潜效益最大化。现场试验表明,近几年通过油水井联动配套工艺优化研究,有效地稳定了油井产量,为区块稳油控水,提升水驱动用程度提供了有力的技术支撑。

Since the development of layered system in Naiman block, the natural decline rate is high due to the imperfect injection production well pattern and water flooding channeling. In view of the production contradiction in the block, it is necessary to actively change the concept, take the stable production of the block as the starting point, take the measures of oil and water wells as the means,strengthen the linkage between oil and water wells, and cooperate with the implementation of low-cost supporting processes such as water plugging, fishing and sealing, drilling plug recovery and so on while promoting the process of fine water injection and deep profile control of water wells,to maximize the potential benefits of measures. The field test shows that in recent years, through the research on the optimization of oil-water well linkage matching process, the oil well production has been effectively stabilized, which provides a strong technical support for stabilizing oil and controlling water and improving the degree of water drive production in the block.
