Shengli Offshore Chengbei 11NC-8 Well was successfully put into production

SINOPEC News Network recently, Shengli Offshore Chengbei 11NC-8 well successfully completed its production operation and joined the exploration and development sequence of Chengdao Oilfield in Shengli Offshore
.

Chengbei 11NC-8 well is located at Chengbei 11N platform on Shengli Sea, about 10 kilometers away from the shore
.

Put into production construction, the newly ejected reservoir is sensitive, and the fluid entering the well can easily be polluted and affect productivity.
In order to effectively protect the formation and maintain long-term development, it is determined that the fluid entering the well is the filter platform injection water + anti-emulsifier + high temperature clay stabilizer (anti-swelling type )
.

The construction adopts one trip of pipe string to implement acidification to remove plugging + high-speed water filling and sand control.
This process is an imported acidification and sand control process.
It is still in the experimental stage in China.
In order to ensure the implementation effect, the 5 oil test team organized various subcontractors according to the actual situation.
Convene construction technology and safety briefing meetings, carefully analyze the characteristics of the stratum, formulate detailed construction plans, carefully plan, scientifically arrange, and strive to be high-quality and efficient
.

In the end, Chengbei 11NC-8 well successfully completed the various procedures of the commissioning operation, and the successful offshore exploration and development added a new force
