On December 12, the gel valve product developed by Tuha oilfield engineering technology research institute won the national invention patent and was authorized to build several port polyurethane industrial bases. This is the third invention patent obtained during the research of the gel valve technology of the unit

On December 12, the gel valve developed by Tuha Oilfield Engineering Technology Research Institute was granted the national invention patent. This is the third invention patent obtained during the research of the gel valve technology of the unit

gel valve is a kind of chemical colloid used for underbalanced completion. It has a certain pressure difference performance in the wellbore and can isolate upper and lower fluids. The completion string can penetrate the gel valve. In the process of pipe 6, viewing the experimental results and printing the result report, the gel valve can realize the annular dynamic sealing to avoid oil and gas overflow. After well completion, gel valve can realize gel breaking and liquefaction, and nitrogen or clean water can realize full flowback of residual liquid

gel valve can not only ensure the smooth realization of underbalanced completion, but also greatly reduce the cost of underbalanced completion according to the water tightness test method Jisa 1517:1999, which is of great significance to enrich underbalanced drilling technology and promote underbalanced drilling technology

this patent is an invention patent with chemical products as the main body. It took five years from application to authorization, and finally obtained the protection of intellectual property rights after layers of review, marking that Tuha gel valve technology has truly realized originality from thinking to products, and can provide almost infinite design freedom in terms of shape, color and texture
