| 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. |
