摘要: 不稳定试井是了解油藏信息、获取地层参数的重要监测技术。目前油田通常采用的压力恢复、压力降落不稳定试井方法要求有一定关井期,对生产影响较大,在高产油井、高注水井中尤为突出,因此探索对生产影响小又能获得油藏信息的新型不稳定试井技术是非常必要的。通过塔里木哈得油田未饱和砂岩油藏超深水平井“变流量不稳定试井”探索实例,证实该技术理论成熟、应用条件明确、实施效果良好,是对水平井试井分析技术的丰富与发展,能有效兼顾生产,为开发调整提供有力技术支持,对油田高产稳产具有积极作用。

Abstract: Pressure transient testing is an important dynamic monitoring technique for obtaining reservoir information and strata parameters. The pressure build-up test and the pressure drawdown test to acquire the formation parameters are usually adopted in the oilfield. But the methods have to need certain closed-in time, which has a great influence to the production, especially to the high-yielding oil well and high-rate water injection well. Hence, a new technique of pressure transient testing is requested to overcome the disadvantage and acquire accurate information of the reservoir. The case study named variable rate transient testing in the ultra-deep horizontal well of the unsaturated sandstone reservoir of Tarim H field shows that the theory is correct, the application condition is specific, the field response is good, indicating that such a horizontal well test technique is a powerful support to the development scheme adjustment while keeping the high-yielding and the production stable in the oilfield.

Key words: unsaturated reservoir, ultra-deep well, horizontal well, pressure transient testing
