From the perspective of the safety of emergency process, in this paper, we put forward a new analysis method of cause factors based on fault tree analysis and modified Bayesian network in emergency process of fire accident for oil–gas storage and transportation. Nineteen cause factors are found based on the statistical analysis of actual accident cases. We adopt fault tree analysis method and Bayesian network model to analyze cause factors qualitatively and quantitatively. In order to more accurately determine the quantitative influencing degree of each cause factor, the conditional probabilities in Bayesian network are modified by using expert scoring method and modified Bayesian network model is established. Finally, the proposed method is applied to analyze cause factors in emergency process of two practical accident cases. Research results have an important scientific significance to reveal evolution mechanism of secondary accidents in emergency process and ensure system safety in whole life cycle.

The existence of interlayers has great influence on the stability of salt cavern. Based on the research results of creep test and other mechanical properties of salt rock and interlayer in Yunying Salt Mine, Hubei Province, cylindrical singular calculation model of salt rock cavity is built, and the corresponding simulation is conducted. Hard interlayer’s constraint influence on the creep contraction deformation of salt cavity is demonstrated. In addition, how the number of interlayers affects cavity radial deformation is discussed too. The results are important to oil-gas storage cavern modeling analysis in laminated salt rock.

This paper takes a 50000 m3 liquefied petroleum gas storage tank in a chemical company in Tianjin for an example, and adopts the fire simulation software FDS to make numerical simulation for the whole-area pool fire accident in the liquefied propane gas tank. The variation of flame and the flue gas in the combustion process of pool fire is obtained from the simulation. The simulation results show that flame shape, smoke production rate and thermal radiation intensity is small in the early pool fire, and significantly increases with the development of combustion process, finally maintains in a relatively stable state.

In order to grasp the change of oil-gas interface in north area of Lamadian Oilfield and determine the conditions of gas or oil invasion during the development of gas storage, the precise geological model is established. By simulation software Eclipse immigrations of gas-oil interface are tracing simulated and cases of gas or oil invasion are monitored under various pressure differentials, based on which the limits of pressure are provided at last. Simulation results indicate that when the pressure of gas region is higher than oil region the gas invasion will happen and when the pressure differential between oil and gas region is up to 0.6 MPa the oil invasion will happen after 16 injection-production cycles. This paper is valuable to practical project applications which keep the interface stable and avoid the gas and oil invasions.
