Tnt Equivalence

In this paper, blast effect of oil-associated gas in gas injection wells is determined when using air injection displacement, and on this basis, the relevant safety distance is determined also. Numerical simulation is used to calculate the overpressure distribution, explosion energy and TNT equivalence of combustible gas explosion in gas injection wells. Based on shock wave damage criterion, the safety distances in seven levels are obtained, which are personnel minor injuries, severe injuries, death, and destruction of buildings with mild, moderate, severe manage and destroying. Therefore, technical support is provided to accident prevention, emergency and rescue.

Sealing Failure

CO2 corrosion for rubber materials makes sealing failure of downwell tools and annulus pressure even, which will endanger the safety production of gas injection wells. The high-temperature high-pressure autoclave was used to test supercritical CO2 corrosion for dumbbell-shaped hydronibrile nitrile with pressure 35MPa, temperature 90°C. The change in mechanical properties and corrosion morphology had been analyzed and compared before and after corrosion test in gas and liquid phase environment. Experimental results show that the hardness of hydronibrile nitrile was hardly changed and no dissolution occurred after corrosion. But the tensile strength decreased by 50%. In engineering design, the influence of corrosion on mechanical properties of rubber should be fully considered, and the mechanical properties of rubber in origin state should not be taken as the basis. The research results have provided evidence for the use of rubber materials in CO2 corrosion environment.
