To deal with the complicated operating condition of oil-gas well engineering and solve the highly nonlinear problem, the finite element software ABAQUS has its unique application value. Based on the features of oil-gas well engineering and the application status of ABAQUS software, this paper first introduces the process and characteristics of oil and gas well engineering simulation based on ABAQUS. Then the key points of software modeling and simulation examples in drilling engineering, ocean drilling engineering, cementing engineering, and completion engineering, are introduced in sequence. On the basis of a large number of the current application cases, this paper concludes the defects and problems in the application of ABAQUS in oil-gas well engineering. From all aspects, all simulations should be combined with field test data and extensive third-party software interfaces. This paper effectively promotes the application of finite element method （FEM） and simplifies the model and boundary conditions.
