Abstract: The Experimental Study on the Influence of Fault on Hydrocarbon Migration and Entrapment

The project will study the influence of fault on hydrocarbon migration and entrapment. A group of two-dimensional scaled physical models are constructed which provide both visualization of the flow patterns and estimates of hydrocarbon migration rates and efficiencies. Different faults and faulted traps are designed by using water-wet quartz sand with different permeability. After a known volume of dyed red oil is injected into the models, fluid pressure can be measured by using ultrasonic velocities, and also we can use the digital-camera to record the hydrocarbon migration process Finally we will make use of the numerical simulation to confirm the experimental results.

The designed experiments aim to study three aspects:
1. Hydrocarbon migration rates in different fault systems.
2. Hydrocarbon migration and entrapment efficiencies in different faulted traps
3. The influence of different migration conduits, patterns and lithology combinations on hydrocarbon secondary migration in faulted traps.

The experimental study on the influence of fault on hydrocarbon migration and entrapment will help to deeply understand the secondary oil migration mechanism in faulted traps, which can especially provide some criteria for quantitative evaluation of fault seal ability.
