Large Displacement Tubing Pump
Project in Shell
At present, the maximum diameter of the tubing pump used in oil production is 95mm and the maximum stroke is 6m. When the reservoir pressure is high, the crude oil viscosity is low, and the oli supply is sufficient, the conventional tubing pump cannot meet the requirements of fluid discharge, so the electric submersible pump is usually used in the oilfield at this time.
Submersible electric pump is characterized by high liquid production and large investment.
Compared with conventional tubing pumps, submersible electric pumps have 50% higher one-time investment and a 350% higher operating cost than conventional tubing pump.
Although submersible electric pump can improve oil production, but its cost performance is not high.
At present, some oilfields use double-action pump to replace submersible electric pump, but the double-action pump has low efficiency, complex structure, high cost, inconvenient operation and short life.
These reasons make it difficult to be widely used.
Therefore, it is necessary to apply the large displacement tubular pump in some oil Wells with high production.
In order to meet the needs of customers, Sanjack carries out research and development of large displacement tubing pumps.

The difficulty in the manufacture of large displacement tubing pump is large inside diameter pump barrel.
The conventional honing process can not meet the requirement of the size precision of the pump barrel.
SANJACK redesigned the production process and adopted the Precision rolling process to produce the pump barrel.
After two years of research and development, SANJACK successfully manufactured the pump barrel with large diameter to meet the requirements of dimensional accuracy.
At present, SANJACK can produce the pump barrel up to 146mm, which is made of low-carbon alloy steel, brass, tin bronze and stainless steel.
SHELL has been ordering Sanjack 120mm tubular pumps for 10 consecutive years.
Since 2018, Weatherford has successively ordered 146mm pump barrel with large displacement from Sanjack.
