At a Glance

Oilfield / Production Plant

Shengli Oilfield – Gudong

Well Conditions

Pump setting deviation 6°, pump setting depth 1,202 m

Production Method

Ambient-temperature cold production (no auxiliary processes)

The Challenge

Sand sticking, heavy string loads, and conventional method failure — triple constraints on cold production

01

High water cut & sand sticking risk

Composite water cut reaches 82%, sand content 0.02%, degassed crude dynamic viscosity 200 mPa·s. Severe sand sticking risk during production.

02

Heavy tubing string load

The well bears a heavy tubing string load, constraining overall production capacity.

03

Conventional methods ineffective

Conventional approaches with friction reducer adjustments failed to restore normal production. The lift system became the capacity bottleneck.

The Solution

HXBS deployed the IntelliCPCP® intelligent conical progressive cavity pump system

A comprehensive lift technology upgrade targeting the core challenges of ambient-temperature cold production in conventional heavy oil.

Tapered rotor-stator clearance allows dynamic gap adjustment and sand-laden production, effectively extending pump inspection cycles.

The system prevents sand burial and reverse rotation during shutdown, prevents scale sticking after steam injection, and auto-lifts to clear sand sticking.

Remote monitoring and parameter adjustment, automatic pump efficiency optimization, enabling unmanned intelligent management.
