Abstract
The utility model discloses a braided river island sand body oil displacement experimental device. The braided river island sand body oil displacement experimental device solves the problems that displacement model is not strong in representation, poor in visuality, and not convenient to observe when oil gas development and research are conducted on a braided river island sand body. The braided river island sand body oil displacement experimental device comprises a sand box, an upper end cover and a lower end cover, the sand box is transparent visible organic glass cylinder, a plurality of reinforcing hoops are sleeved on the side wall of the sand box, three communicating holes which penetrate through the sand box wall are formed in the walls of the reinforcing hoops, and a pressure sensor, a thermocouple and a differential pressure transducer are respectively inserted into the three communicating holes. Both ends of the sand box are respectively closed by the upper end cover and the lower end cover, and an injection hole and an extraction hole are formed in the surface of the upper end cover. The conditions such as leakage of oil water and oil displacement in the sand can be directly observed by a microscope, and at the same time, after the microscope is connected with a computer in an on-line mode, saturation distribution and size of the oil water in the process of displacement of a micro-pore structure can be quantitatively described by a corresponding software, and a scientific basis is provided for development and research of braided river island sand body oil gas.
Description
Technical field
The utility model relates to a kind of geology sandpack column, concrete is under the braided stream deposit background, oil and gas reservoir is mainly the channel bar sand body that the long-pending mode of hanging down forms, for effectively observing by displacement oil gas in underground migration state and path, and simulation braided stream channel bar sand body and the sandpack column that designs.
Background technology
At present, carrying out the research of law of hydrocarbon migration, remaining oil distribution position and oil displacement efficiency for braided stream channel bar sand body, mainly is to do rock core displacement test, but the rock core volume is very little, and for whole braided stream channel bar sand body, its representativeness is not strong, and visuality is not good, is inconvenient to observe.So need a kind of physical analogy model of simulating braided stream channel bar sand body, for the oil and gas development research of this reservoir provides safeguard.
Summary of the invention
The purpose of this utility model provides a kind of physical simulating device that carries out oil and gas development research for braided stream channel bar sand body, and this analogue means is stereo chamber type, and three-dimensional visible is strong, but the Continuous Observation record.
For achieving the above object, the technical solution adopted in the utility model is: braided stream channel bar sand body oil displacement experiment device, comprise sandbox, upper end cover, bottom end cover and be placed on the microscope of sandbox side, sandbox is transparent visual organic glass cylinder, load corresponding sandstone and clay according to river island sand body earth formation and composition in the sandbox, the sidewall sheath of sandbox has some reinforcement hoops, strengthen the hoop wall at each three intercommunicating pores that connect the sandbox wall are set, insert respectively pressure sensor, thermocouple and differential pressure pickup in these three intercommunicating pores; In addition, slot is set respectively on upper end cover and the bottom end cover, the built-in sealing ring of slot, the two-port of sandbox is inserted respectively in the slot of upper end cover and bottom end cover, and the slot inboard on upper end cover surface also arranges injection hole and extraction hole.
In order to reinforce sandbox, some circular holes preferably are set respectively on upper end cover and bottom end cover, above-mentioned circular hole is distributed on the slot outside, and the circular hole on upper end cover and the bottom end cover is concentric in twos, penetrates respectively screw rod in the concentric circular hole in twos, and the screw rod two ends are fixed with nut.
Beneficial effect: the visual sandbox by ultramicroscopic observation the application during experiment, can observe intuitively seepage flow situation and the oily expelling water, water drive oil of profit in model, residual oil distribution situation behind polymer flooding and other chemical flooding; Simultaneously by with the microscope of acquisition port during displacement each step mobility status of fluid by the software Real-time Collection to computer, but profit saturation distribution and size in the quantitative description micropore structure displacement process are for the research of braided stream channel bar sand body oil and gas development provides scientific basis.
