近年来,水平井压裂技术已经比较成熟完善,水平井开发作为提高单井产量及采收率的重要手段已在国内各油气田得到广泛应用。形成了相对成熟完善的低品位油气层水平井压裂建产技术,为低品位储量动用提供了的技术支撑。然而在大牛气田的开发应用中证明,有些储层利用水平井建产后效果并不理想。本文将以大牛地气田下石盒子组盒1,山西组山1和太原组太1储层为例做对比,从地质因素方面进行分析,讨论水平井建产开发的适应性。
In recent years, horizontal well fracturing technology has been relatively mature and perfect. As an important means to improve single well production and oil recovery, horizontal well development has been widely used in all domestic oil and gas fields. Formed a relatively mature and perfect horizontal well fracturing technology for low-grade oil and gas reservoirs, and provided technical support for the utilization of low-grade reserves. However, in the development and application of Daniu gas field, it is proved that some reservoirs will not be effective after they are built with horizontal wells. In this paper, we will compare the Boxes 1, Xiaoshan 1, Shanxi Province, and the Taiyuan Formation, Taiyuan Formation in Daniudi Gas Field, and analyze the geological factors to discuss the adaptability of horizontal well construction and development.
