R&D History

Core Technology Directions

The page organizes gyro survey, intelligent lift / gas lift, and pulser work into three technical directions, with milestones, validation scenes, and public-facing materials.

01

Gyro Survey

Gyro Survey / MWD Gyro R&D Direction

Built around continuous measurement, MWD gyro, autonomous north seeking, anti-magnetic interference, and wellbore trajectory survey, with integrated equipment, surface unit, GYRO software, and field service capabilities.

  1. Technical baseContinuous gyro survey, MWD gyro, north seeking, and wellbore trajectory measurement capabilities took shape.
  2. Product developmentIntegrated continuous gyro survey tool, surface unit, and supporting fixtures were systematically developed.
  3. Testing and validationCalibration, verification-bench testing, production maintenance, and field feedback improved stability.
  4. Field applicationDelivery and project support cover offshore, onshore, and complex well conditions.

02

Intelligent Lift

Intelligent Lift / Gas-Lift R&D Direction

Focused on ball-lift / gas-lift principles, launching and receiving devices, ball circulation, experimental systems, and field adaptability.

  1. 1990 / 1996Early patent foundation represented by Wu Chenglin's 1990 patent A Gas-Lift Oil Production Device (《一种气举采油装置》), experimental device development, and technical exchange around the World Petroleum Congress in Beijing.
  2. 2006Field trials at CNPC Southwest Bureau Engineering Institute Well 26 and by Southwest Petroleum University Professor Li Yingchuan's team.
  3. 2020Patent application for Wu's golf gas-lift concept advanced the next R&D phase.
  4. 2026Japan and U.S. patent grants expanded the international disclosure base.

03

Pulser

Pulser R&D Direction

Covers pulser structure research, prototype assembly, field testing, and water-circulation verification for technical communication.

  1. 2014Pulser direction initiated with structure, function, and application positioning.
  2. Summer 2018Field testing in Shanxi generated prototype verification materials.
  3. Oct. 2018Downhole test in Xinjiang validated field adaptability.
  4. Ongoing verificationWater-circulation testing, component checks, and assembly management support structural optimization.
