海上油田油套管数据库构建与智能推荐方法研究

海洋石油开发过程中面临着复杂多样的储层环境，对油套管的强度、密封性等性能提出了严格要求，合理选择适合的油套管对油气钻采至关重要。本文首先对渤海、东海、南海东部、南海西部海域进行了基础数据的收集，主要包括油田分布情况、油气藏特点；并进行双变量相关性分析，明确了海况参数与油套管技术参数的相关性。在此基础上，根据不同储层地质特点和差异建立了适用于各海域的海上油田油套管推荐体系；采用Django+MySQL为开发工具进行开发，形成一套基于Web前端的海上油田油套管数据库管理系统；最后通过渤海海域埕北油田M1井应用案例测试，获得合适的油套管推荐方案，验证了该海上油田油套管数据库的实用性。海上油田油套管管理系统的建立能够高效、科学的管理油套管的应用信息，有利于未来海上油田的开发。

Research on Database Construction and Intelligent Recommendation Method for Tubing and Casing Pipe in Offshore Oil Field

The offshore oil development is faced with complex and diverse reservoir environment, which puts forward strict requirements on the strength and tightness of oil casing, and reasonable selection of suitable oil casing is very important for oil and gas drilling and production. Firstly, the basic data of Bohai Sea, East China Sea, East South China Sea and West South China Sea are collected, including oilfield distribution and reservoir characteristics. The correlation between the parameters of sea state and the technical parameters of oil casing is confirmed by bivariate correlation analysis. On this basis, according to the geological characteristics and differences of different reservoirs, a recommended casing system for offshore oil fields is established. Using Django & MySQL as development tool, a set of offshore oil casing database management system based on Web front-end is formed. Finally, through the application case test of M1 well in Chengbei Oilfield, Bohai Sea, a suitable casing recommendation scheme is obtained, and the practicability of the offshore oil casing database is verified. The establishment of offshore oil casing management system can efficiently and scientifically manage the application information of oil casing, which is conducive to the development of offshore oil fields in the future.
