王场油田北断块高含水开发期稳产技术对策

Countermeasures for Stabilized Production in North Fault Block of Wangchang Oilfield at High Water-cut Producing Stage

针对王场油田潜三段北断块高含水开发期暴露出来的诸如油藏含水高、采出程度高、水淹程度高、油水分布状况复杂及井是、层间干扰严重的主要问题,提出了4种稳产技术对策:重组调整注采井网;整体应用水动力学理论;优化措施方案;开展配套工艺技术的研究。现场实践表明稳产效果显著。

In consideration of the main problems, such as water content in reservoirs, high recovery ratio, high water-out extent, complicated oil and gas distribution and serious interference of interwells and interbeds in the north block of Section Qian 3 in Wangchang Oilfield, 4 countermeasures for stabilized production are proposed, including adjusting and reconstructing injection production well pattern, integral application of hydraulic theory, optimizing stimulation project and conducting matching technical study. Field practice indicates that the effect of stabilized production is obvious.
