Problems solved by technology

[0011] The existing physical simulations of oil and gas migration and accumulation mechanisms are basically carried out in a large sandbox. Different geological models are constructed in the sandbox to simulate or verify the laws of oil and gas migration and accumulation in a certain area. Specially designed for the physical model design of formation sand body-unconformity surface-fault oil and gas migration, and the experiment of researching formation sand body-unconformity surface-fault oil control mechanism by changing the spatial configuration of formation sand body-unconformity surface-fault Apparatus and Experimental Method

Embodiment 1

[0057] Embodiment 1: as figure 1 As shown, an experimental device for oil migration control of sand body-unconformity surface-fault transport system, including a simulator with a fluid injection port 1 and a fluid output port 2, and a fluid injection port connected to the fluid injection port 1 of the simulator. Inlet pressure control system, the simulator includes a bottom sand box 3 and a side sand box located at the end of the bottom sand box 3, the bottom sand box 3 is movably connected with the side sand box, and the bottom sand box 3 and the side sand box Slot plates 7 freely sliding on the sand box are respectively provided, and a slot plate 8 with a cavity is inserted between the slot plate 7 of the bottom sand box and the slot plate 7 of the side sand box 5 . Since the bottom sand box 3 is movably connected with the side sand box, the side sand box can swing freely, thereby changing the inclination angle of the side sand box, that is, changing the inclination angle of...

Embodiment 2

[0070] Embodiment 2: The difference from the specific embodiment 1 is that the sand body-unconformity-fault transport system described in the embodiment 2 is an experimental device for controlling oil migration, and its inserting plate is designed to be convex. It is suitable for simulating unconformity surfaces with convex shapes in natural geological bodies.

Embodiment 3

[0071] Embodiment 3: The difference from the specific embodiment 1 is that the sand body-unconformity-fault transport system described in the embodiment 3 is an experimental device for controlling oil migration, and its inserting plate is designed to be concave. It is suitable for simulating unconformity surfaces with concave shapes in natural geological bodies.

Abstract

The invention relates to a sand body-unconformity surface-fault conducting system oil control transport experiment device and experiment method. The experiment device includes a simulator provided with a fluid injection port and a fluid output port, and a fluid injection port pressure control system connected with the fluid injection port of the simulator; the simulator includes a bottom sand box and a side sand box located at the end part of the bottom sand box, the bottom sand box is movably connected with the side sand box, the bottom sand box and the side sand box are respectively provided with slot boards freely sliding on the sand boxes, and an inserting board with a cavity is inserted between the slot board of the bottom sand box and the slot board of the side sand box. An oil gas transport and accumulation process in a sand body-unconformity surface-fault conducting body space mode is simulated, rules and control factors affecting transport and accumulation of oil gas along the sand body-unconformity surface-fault conducting body are analyzed, understanding of cause of oil gas accumulation and oil gas distribution rule is deepened, a basis is provided for oil gas exploration of oil gas containing basins, and at the same time, a service is well provided for experimental teaching.

Description

technical field [0001] The present invention relates to an experimental device and an experimental method for oil and gas migration and accumulation, in particular to a physical simulation device and an experimental method for controlling oil migration of a sand body-unconformity surface-fault transport system, by changing the sand body-unconformity surface -The configuration relationship of faults, so as to trace the sand body-unconformity surface-fault control oil migration path and physical simulation method of migration process. Background technique [0002] After the initial migration and expulsion of hydrocarbons from the source rock, oil and gas enter the trap through secondary migration in the migration channel before entering the trap. These main migration pathways include carrier layers (sand bodies with high porosity and permeability), unconformity surfaces, faults and combinations of these three types. [0003] Sand bodies are the most basic and important migrat...
