Products and Services

lIn the field of cementing technical research, RIET is superior in cementing jobs under many kinds of difficult conditions, which involve deep wells & extremely deep wells, long sealed columns with low pressure and leakage, under-balanced drilling, long sealed columns, high pressure gas wells, and rock formation. So far, RIET has developed 10 series of cementing materials amounting to 60 types of products, which have been successfully used in over 1,000 cementing operations in 15 oil fields like Changqing oil field and Dagang oil field, and in Bohai Sea cementing projects of PHILLIPS. Moreover, a couple of types of additives have been exported to overseas market, for instance, TABAK zones in IRAN and VENEZUELA, etc.l In the realm of other technical research regarding engineering, RIET created four products that are popular among domestic clients. Type AW-01 Frication-reducing Durable Coating for natural gas pipeline provides a new technology for the inner coating of natural gas conveying pipeline of China. Tests conducted by relevant international and domestic authoritative testing institutes showed that this product can increase the result of gas conveyance by more than 15%, and has the same properties as that of Copon BP2306 coating of England and Permecor 337 coating of Germany.
