Jiangsu Oilfield is carefully looking for the spring to restart the development of the old area

After more than 40 years of development in the oil field, most of the oilfields of Jiangsu Oilfield No.

Prior to this, Well Bianzhen 67A was in a state of low liquid and low production for a long time.

This year, the plant closely focused on the “38,000 tons+” mission goal of the old area’s measures to allocate production, strengthened reservoir research centered on remaining oil, and accurately guided the water through stratigraphic correlation, microstructure description, and reservoir sedimentary microfacies description.

In January, researchers from this plant carried out research on the difference of sedimentary facies in combination with the changes in the injection and production well pattern, inferred the different flooding mechanisms of different sedimentary facies, and took measures to improve the water flooded layers in the high part of the Fu 18 block and Fu 136 well.

In February, they finely depicted the structural contour lines of the sand body of the second member of the Dai 2 in the Zhen 11 fault block, from 20 meters to 2 meters in order.

Taking a foothold in old areas and reviewing old wells is an important way to increase reserves and production in old oilfields, and it is also an effective method for rolling exploration in old areas.
