【摘要】：苏里格气田具有典型的低渗、相变快、厚度薄、直井低产、稳产时间短的特点。针对这一制约开发的特点,开展了水平井优选部井和参数优化及地质导向技术研究。通过地质地震和生产资料分析研究,优选出了苏53-4井区为水平井部署区。建立三维地质模型,确定了合理的参数,进行了数值模拟,对水平井的各项参数进行了优化。得到了合理的水平井井网井距、水平段方位、长度等参数,为水平井有效开发提供了基本的保障。实施过程中,应用了水平井地质导向技术,大大提高了水平井的有效储层钻遇率,降低了钻井风险,为后续工作打下了很好的基础。水平井技术的应用,在苏53区块取得了很好的开发效果,2年时间实现了以38口水平井完成了10亿方产能的建设。利用水平井整体开发低渗气藏非常成功,选出的水平井部署区非常成功,设计的水平井参数也非常合理。
[Abstract]:Sulige gas field is characterized by typical low permeability, fast phase transition, thin thickness, low production in vertical wells and short stable production time. According to the characteristic of restricting development, the research on optimum selection and parameter optimization and geological guidance technology of horizontal well is carried out. Through the analysis of geological seismicity and production data, Su-53-4 well area is selected as horizontal well deployment area. Three dimensional geological model was established, reasonable parameters were determined, numerical simulation was carried out, and various parameters of horizontal well were optimized. Reasonable horizontal well spacing, horizontal section azimuth, length and other parameters are obtained, which provides a basic guarantee for the effective development of horizontal wells. In the process of implementation, the geological guidance technology of horizontal well is applied, which greatly improves the effective drilling rate of horizontal well, reduces the drilling risk, and lays a good foundation for the follow-up work. The application of horizontal well technology has achieved a good development effect in Su53 block. In 2 years, 38 horizontal wells have completed the construction of 1 billion production capacity. It is very successful to develop low permeability gas reservoir by using horizontal well as a whole, the selected horizontal well deployment area is very successful, and the design parameters of horizontal well are also very reasonable.
