A few days ago, news came from the Xianhe oil production plant in Shengli Oilfield that the fourth block of Cao 13 Sha 4 of the plant will be expanded from two well groups to six well groups on the basis of the breakthrough effect of microbial flooding.
The overall plan involves 23 wells
.

It is understood that after the addition of microbial flooding, the block will add 10,000 tons of new production capacity and increase the recovery rate by 8.

The Cao 13 Sha 4 block belongs to the Le'an Oilfield of Xianhe Oil Production Plant.
It is a multi-thin and sensitive ordinary heavy oil reservoir with an oil-bearing area of 3.
96 square kilometers and a geological reserve of 3.
72 million tons
.

The block was put into production in 2013 for fracturing and sand control.

This time the expansion of 23 wells in 6 well groups, including 17 oil wells and 6 water wells, is planned to be divided into two sets of layers to implement intelligent split injection
.

At present, the technicians of the Institute of Microbiology of Shengli Petroleum Engineering Technology Research Institute are actively cooperating with the oil production plant in the ground construction of microbial injection equipment and the optimization of the microbial system
