随着现代水平钻井技术的不断进步和发展,往往可以在一口水平井上开发出多个连续的薄油藏来,这样既能够有效的降低油田的开采成本,还能够提高单井的出油量和采收率,可谓是一举多得。本文就是基于这样一种状况,针对于大庆油田外围油藏的特点,在分析其水平井钻井技术难点的基础上,对其井身结构和剖面进行了优化的设计,并从多个具体的方面对大庆油田薄油层的水平井钻井技术展开了研究和讨论。
With the continuous improvement and development of modern horizontal drilling technology, it is often possible to develop multiple continuous thin reservoirs on a single horizontal well. This not only effectively reduces the cost of oilfield exploration, but also increases the output of a single well Oil recovery, can be described as one stroke. This article is based on such a situation. In view of the characteristics of the peripheral reservoirs in Daqing Oilfield, based on the analysis of technical difficulties of its horizontal well drilling, the well structure and profile of the horizontal well are optimized design, and from a number of specific aspects The research and discussion on the horizontal well drilling technology in thin reservoirs of Daqing Oilfield has been carried out.
