Henan Oilfield Oil Production Plant a sub-pumping mixed pump significantly increased oil production

Henan Oilfield Oil Production Plant recently applied sub-pumping mixed pumping layered oil production technology, significant oil increase.

Divided pumping out of the pump stratified oil production technology, the use of packer will be two layers of stable separation of the reservoir into two independent systems, the use of sub-pumping pump out pumping.

Sub-pumping mixing pump from top to bottom two tandem pump composition, connected by a hollow rod, each pump has its own separate inlet valve and drain valve, pumping oil, the pump pumping the upper liquid, the pump Pumping sub-liquid, to solve the conventional measures to plug a layer to solve the interference caused by different pressure between layers, thereby enhancing the oil production rate.

Since the beginning of this year, a total of 9 wells have been implemented in the first oil production plant of Henan Oilfield, with a total increase of 1445 tons of crude oil.
