Analysis of Drill Collar Fracture in a Well with H2S
The drill collar fracture accident in a H2S-containing well was studied.The fracture showed intergranular morphology and the sulfur content was higher in the cracks than that in the other area of the drill collar.It is concluded that the drill collar material is in accordance with SY/T 5144-1997 standard requirement,and the fracture resulted from sulfide stress corrosion crack(SSCC).
