건설분야 최고의 해석 솔루션 DIANA와 함께 합니다.

DIANA

Oil & Gas

오일과 가스의 매장이나 웰보어의 지반역학적 해석은 이러한 목적에 잘 맞는 재료, 요소 및 해석 기능들의 확장된 라이브러리로서 DIANA의 특별한 기능 중 하나이다.
DIANA는 아래의 기능들을 포함하고 있습니다.
  • non-linear material models for fracturing
  • shear-failure
  • creep and crushing of rock and frictional fault modelling
  • automatic meshing procedures for 3D formations starting from geological model data
  • distributed pressure fields and material properties
  • anisotropic material models for up-scaling
  • automatic and user defined solutions procedures for nonlinear problems
  • thermal and flow-stress effects
  • efficient direct and iterative parallel-processing solvers
  • powerful visualization of models and results

DIANA는 오일과 가스의 생산과 관련되거나 생산의 결과로서 발생되는 암석의 압축, 응력 변화, 매장된
장소의 절리부 활동, 과부하, 지표 침하 등을 정량화하는데 도움을 줄 것입니다. DIANA는 암석의 파괴, 케이싱
변형, 유정이 완료될 동안의 시멘트 무결성, 압력이나 온도 충격, 절리 활동에 의한 작동 조건 등을 정량화 하여
웰보어의 규모를 정의하는데 사용될 수 있습니다.
더욱이 DIANA는 서로 다른 여러 개의 해석이 하나의 해석 케이스에서 수행될 수 있도록 구성되어 있습니다.
