Application and Practice of New Anti-blocking Technology in Offshore Oil Field

The establishment of a long-term anti-blocking mechanism aims to relieve the clogging of mud and sand during the development of the reservoir and release the reservoir productivity. In response to the sharp decline in production capacity of high argillaceous loose sandstone heavy oil fields, the application of CPI anti-blocking technology, which integrates sand control and water control, will increase the target horizontal well fluid volume by 2 times, simultaneously with the daily oil production increasing by 2.85 times and fluid production index increasing by 1.75 times. Finally, effective methods were found in this paper for the treatment of target oil fields, which have high promotion value for the development of similar oil fields.
