Jiangsu Oilfield injected more than 300 tons of carbon dioxide per day and established a special class to vigorously promote the resumption of production

On May 30, Jiangsu Oilfield overcame the adverse effects of the epidemic, and the daily injection of carbon dioxide flooding exceeded 300 tons, and embarked on the
step of 100,000 tons per year.

Jiangsu Oilfield plans to inject 100,000 tons of carbon dioxide this year and increase crude oil production by 30,000 tons, and the epidemic sealing and control has had a serious impact on
the cross-regional transportation of carbon dioxide and the construction of oil flooding wells.
The transportation of carbon dioxide raw materials in Jiangsu oilfield involves Nanjing, Taizhou, Yangzhou in Jiangsu Province, and Chuzhou in Anhui, and the flooding wells are distributed in Jiangdu, Hanjiang, Tianchang and other counties and urban areas
.
Since March, carbon dioxide transportation has been interrupted, and the oil flooding well has been in a state of
"no rice under the pot".
The carbon dioxide project team of this oilfield did not wait and did not rely on it, selected wells for research according to plan, tackled technical difficulties and bottlenecks, and reserved a number of carbon dioxide flooding wells
.

Since mid-May, with the epidemic situation in the surrounding areas of Yangzhou being effectively controlled and traffic in the province recovering in an orderly manner, Jiangsu Oilfield has grasped the prevention and control of the epidemic on the one hand and the carbon dioxide flooding oil well on
the other hand.
The oilfield has formulated a work target and implementation plan for striving to achieve a production of 100,000 tons in 50 days (daily injection level), compiled an operation table, and clarified the time node
for task completion.
The Exploration and Development Research Institute optimized the flooding scheme, injected 26 pieces, 17 flowers, 38 pieces and 95 whole blocks to ensure that the daily oil increase was more than 60 tons, and the Petroleum Engineering Technology Research Institute and the oil production plant were closely integrated, and Lectra was difficult to
inject carbon and corrosion prevention.

The two oil production plants set up special classes for carbon dioxide projects, joined hands with local governments to respond to the epidemic, strengthen coordination between oil and land, and maximize the protection of oilfield production
while jointly preventing and controlling the epidemic.
In view of the control measures for foreign carbon dioxide logistics drivers not getting off the vehicle throughout the process, they localized the construction vehicles such as hoisting to ensure that carbon dioxide enters the site in time and repays
in time.

At present, the carbon dioxide flooding injection of the two oil production plants in Jiangsu Oilfield is running as planned, and the oilfield-level carbon dioxide project team has completed the construction of the CCUS-EOR (carbon dioxide capture and storage and enhanced oil recovery) project of complex small fault block oilfield with 38 demonstration areas, with a daily injection of 50 tons of carbon dioxide and a daily output of more than 20 tons of crude oil, the amount of underground carbon buried is greater than the amount of carbon emissions from production, and the oil reservoir recovery rate has increased from 7.
31% to 21.
89%.
