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] Example 1: as figure 1 As shown, a sand body-unconformity surface-fault transport system controlled oil migration experimental device includes a simulator provided 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 flask 3 and a side flask at the end of the bottom flask 3, the bottom flask 3 is movably connected with the side flask, the bottom flask 3 and the side flask There are slot plates 7 that slide freely on the flasks, respectively, and a slot plate 8 with a cavity is inserted between the slot plate 7 of the bottom flask and the slot plate 7 of the side flask 5 . Since the bottom flask 3 is movably connected with the side flask, the side flask can swing freely, thereby changing the inclination angle of the side flask, that is, changing the dip angle of the longitudinal fault. At the same time, since the slot pl...

Embodiment 2

[0070] Example 2: Different from the specific example 1, in the sand body-unconformity surface-fault transport system oil control and migration experimental device described in the example 2, the insert plate is designed to be convex. It is suitable for simulating the unconformity surface of the convex shape in the natural geological body.

Embodiment 3

[0071] Example 3: Different from the specific example 1, in the sand body-unconformity surface-fault transport system oil control and migration experimental device described in Example 3, the insert plate is designed to be concave. Unconformity surfaces suitable for simulating 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 invention relates to an experimental device and an experimental method for oil and gas migration and accumulation, in particular to a physical simulation experimental device and an experimental method for controlling oil migration in a sand body-unconformity surface-fault transport system. It is a physical simulation method that traces the sand body-unconformity surface-fault-controlled oil migration path and 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 in the process before entering the trap. These main migration channels include transport layers (high porosity and permeability sand bodies), unconformity surfaces, faults and combinations of these three types. [0003] Sand bodies are the most basic and most important migration channels for oil and gas migration in basins. Sand body is...
