54mm Cased Hole Well Tractor


Introduction

SITAN 54mm Cased Hole Well Tractor with 54mm OD, which can draw logging tools and down-hole equipment to target layers in horizontal wells and high-angle wellbores, completing the logging tasks and deployment. SITAN 54mm Cased Hole Well Tractor can replace the method of drill pipe transmission, which can help user to save costs and improve efficiency. The outer diameter is small, which can realize the traction device for logging through the tubing in horizontal wells, which is used to replace the method of feeding the drill pipe, and rely on its traction force to send the logging instrument to the target layer to complete the logging construction task, which has the advantages of cost saving and improvement. The advantage of aging.


The cased-hole well tractor includes:

  • 1. Surface part.
  • a. Power the downhole equipment.
  • b. Different power supply modes to determine downhole logging tools work or well tractor works.
  • c. Control the drive pushing mechanism and traction mechanism.
  • d. Monitor the working status of pushing and pulling equipment.
  • e. Adjust the pulling speed of the puller by changing the supply voltage.
  • f. Support the communication between the downhole electronic circuit section and the surface.


Noise Logging Tool

SITAN MP series Noise Logging Tool adopts the method of measuring natural noises in the well. When liquid or gas move in the well, the friction between the liquid or gas and the tubing/casing wall generates sound with a certain characteristic spectrum.

Introduction

SITAN MP series Noise Logging Tool adopts the method of measuring natural noises in the well. When liquid or gas move in the well, the friction between the liquid or gas and the tubing/casing wall generates sound with a certain characteristic spectrum.


Feature

  • 1. No need to contact casing, no pollution, no radiation.
  • 2. Detection of casing leakage and bypass channel of the outside pipe according to measured sound frequency.
  • 3. Dual working modes: real-time and memory.
  • 4. High receive sensitivity.
  • 5. Can connect with Multi Finger Caliper (MFC) and other instruments to measure the actual conditions of wells more comprehensively.

    • Aplication

    • 1. Determination of the channeling position outside the casing.
    • 2. Identification of casing or tubing leaks.
    • 3. Determination of case collar leakage
    • 4. Identification of leaking materials in wells (water, gas, and oil).
    • 5. Analysis of cementing quality.

Introduction

SITAN sonic logging tool has two transmitters and four receivers, which are used to measure the time difference of formation longitudinal wave to get formation lithology and porosity. The sonic logging tool can provide a P-wave time difference curve, then compensate for the irregular borehole's influence with the depth compensation method.
