Richfrp was founded in 2001.  It is an comprehensive economic entity in developing, manufacturing and selling of petrol logging instrument and its high temperature pressurized composite insulating instance.


  • Petroleum well logging composite insulation rod
    High temperature compression composite insulator rods for petroleum well logging instruments,it processed with vacuum injection pull-protrusion technology, bobble-free, with high density and high electric insulation level....

  • 1. It produced with high temperature-resistant HTV, all parameters can be met in high temperature pressure. 
    2. Produced with high acid-resistant material and with introducing nano-metric abrasion-resistant material, corrosion free in acid medium(H2S、SO2) which elongates its lifetime.
    3. Capable to make metallic processing such as turning, milling, planing, grinding, b[ring and screwing, no layer, scrap, crack may occur and with satisfactory roughness on finished surface.
    4. No dimension change in diameter at temperature rise from room temperature to 240℃ with maintaining for 1 h, and longitudinal linear variation of 0.01-0.015/m, electric insulation≥500MΩ.
    5. Rods ofФ40、Ф50、Ф60、Ф70、Ф80、Ф90、Ф100、Ф110、Ф127、Ф130 in diameter are available, with length dimension as required by customers.
  • Petroleum well logging composite insulation tube
    High temperature compression composite insulator tubes for Oil well logging instrument...

  • 1. All impregnating process is performed at vacuum to ensure a high density(≥2.0g/cm3), high gas-tightness and superior insulation performance of produce. 
    2. All raw materials of high temperature pressurized insulating tube special for petrol loggerinstrument are imported.
    3. Abrasive-resistant nano-metric material is introduced in high-temperature resistant resincompound for keeping outer surface of tube free of wear at long time contact with well wall and extending logging insruments lifetime. 
    4. Thermo-resistant resin is used to ensure all performance free of degradation at 260℃(175℃)、170Mpa(140Mpa) to meet service conditions.
    5. High acid-resistant composition is used in production to ensure longtime corrosion-resistant ability of tubes at high temperature and acid medium(H2S、SO2)under the well.
    6. Capable to make metallic processing such as turning, milling, planing, grinding, bring and screwing, no layer, scrap, crack may occur.
  • Non-magnetic rubber centralizer
    non-magnetic rubber centralizer is one of the most important petroleum drilling apparatus accessories that our company designed, from the beginning till now, its design and prcess levels are improned after continuous great efforts....

  • The operation conditions of the non-magntie rubber centralizer:
    1. Can be used in weak-acid or alkaline drilling mud conditions;
    2. The max operation temperature is 150℃.
    3. Accumulative serice life is no less than 300 hur (The actual service life varies according to the character of drilling mud and other correlative factors).
    The metallic materials body of centralizer usually is chosen form Monel alloy, non-magnetic stinless steel, Ti alloy or beryllium bronze alloy, etc.

    The centralizer is composed of two parts:anti-corrosive, abrasion resistant, non-magnetic alloy body and elastomer with strong abrasion resistance coated over the body. The Specified vulcanization process was laid down in order to keep the elastomer layer sticking firmly with alloy body under harsh environment with high downhole temperature and high speed drilling mud erosion.
