The pressure difference receiving module of pressure difference pump realizes that the pressure difference inside wellbore model minimizes by its internal control circuit.It is tightly attached to steel
Pressure-bearing film inside simulation wellbore hole processed and the high-pressure fluid collective effect being pumped into pit shaft, prevent the back-up sand caused by pressure difference
Sand body to during the migration of branch well shaft tapping and saturated water, oil, to tapping migrate by fluid in case.
The embedding threaded cross knob in inside at outlet end, the metal closures of the embedded outlet end seal plate of its underpart connection,
It is connected through a screw thread, can realize the installing of the metal closures, disassembling function, it is real to prepare experiment rock core, water drive oil in back-up sand
It is loaded into outlet end seal plate when testing, realizes that the sealing of experimental situation keeps pressure；It is removed during saturated water, oil,
Realize the function of extra fluid discharge back-up sand case.
The pressurization of three screw thread aperture apparatus of arrival end squeeze board and voltage stabilizing feeding device group, can pass through its hydraulic device
By the agglutination sand compacting in back-up sand case；By door latch type feed liquor voltage-stabiliser tube, sealing is played during being compacted agglutination sand and is kept
The function of pressure provides the liquid flow inlet of injection fluid during saturated water, oil and oil displacement experiment.
Used electronic balance during saturated water can play the function of the quality to metering back-up sand case in real time, when
After saturated water, back-up sand bottom portion there are flowing out a period of time back-up sand case constant mass it is constant after, of poor quality can be calculated with front and back
Go out to calculate porosity.
Steps are as follows for this experimental provision specifically used：
a）It is compacted cementing back-up sand case：The set of device of arrival end squeeze board is removed from back-up sand case, toward inside back-up sand case
Add simulation core sand and cementing agent, cover arrival end squeeze board after filling, envelope is encrypted between squeeze board and back-up sand babinet
Liquid；The pressure difference input unit that pressure difference pumps is connect with the differential pressure pickup in horizontal well pit shaft, pumping hole goes out liquid with horizontal well pit shaft
End is connected, and pumping hole is connected with current divider, and three eyelets are connected to hydraulic device fluid inlet end, and intervening vaive is opened, opened
Pressure difference pump is opened, fluid is pumped into simultaneously in horizontal well pit shaft and hydraulic device, so that pit shaft and hydraulic pressure is filled by pressure difference input unit
It sets when being pumped into fluid, the pressure difference of generation as possible small, 0 or so, to ensure the pressure at the pressure-bearing film both ends of son field inner close fitting
Difference is 0 or so, to prevent the high pressure sand body in back-up sand case from penetrating into the seepage flow hole of son field；According to the pressure of hydraulic device bottom
Pressure ensures that its numerical value in confining pressure value or so, passes through valve by the switch pumped by pressure difference in sensor real time monitoring back-up sand case
Pressure caused by three hydraulic devices is identical, and compacting a period of time, the experimentation of compaction simulation rock core terminates.
b）Back-up sand case saturated water/oil：It removes in outlet end seal plate and goes out liquid plug, hose is connected to out the sky that liquid plug is conceded
Between on, after receiving saturated water, back-up sand case outflow liquid；Pressure difference is pumped is pumped into stream into hydraulic device and horizontal well pit shaft
Body so that horizontal well pit shaft inside and outside differential pressure is 0, prevents cementing sand body and the water of saturation from going deep into well by the seepage flow hole on son field
In cylinder；Constant speed pump connects intermediate receptacle bottom, and water/oil is housed in intermediate receptacle；It is connected to current divider at the top of intermediate receptacle, is shunted
Three eyelets of device are connected to the inlet of door latch type feed liquor voltage-stabiliser tube；The pipeline that current divider picks out and door latch type feed liquor voltage-stabiliser tube
Movable cylindric hollow fluid flow tube docking, withstand the former and withstand the latter to moving along a straight line in voltage-stabiliser tube, liquid stream bottom of the tube top
The firmly triangulo column in rectangle cavity makes it due to the outer force effect by fluid flow tube, and it is downward that component makes it press against spring
Movement, to which triangulo column is headed into cuboid cavity lower part, it is logical with back-up sand case Inner Constitution liquid stream that fluid flow tube ejects voltage-stabiliser tube
Road；Intermediate receptacle starts to inject water/oil into back-up sand case, starts the process of saturation；Electronic balance positioned at back-up sand lower box part is
When read back-up sand case system quality, with before water record a mass figures, when outlet end seal plate at outlet end outflow
Fluid, electronic balance stable reading after, record a mass figures, can calculate back-up sand case gap body with the difference of the two
Product, the saturation degree of simulation core；The process of saturated oils is carried out later；Turn off constant speed pump, the experimentation knot of saturated water/oil later
Beam.
c）Oil displacement experiment：Pressure difference pump and compressive film are removed, horizontal well outlet end is connected to metering device, for measuring production
Go out liquid；Constant speed pump connects intermediate receptacle bottom, the displacing fluid in intermediate receptacle is pumped into current divider, current divider injects displacing fluid
Door latch type feed liquor voltage-stabiliser tube starts the experimentation of displacement hence into back-up sand case；Constant pressure pump connects current divider, by fluid
It is pumped into hydraulic device, the confining pressure of simulation core is maintained in conjunction with the pressure sensor of hydraulic device bottom；After completing oil displacement experiment, close
Constant speed pump and constant pressure pump are closed, arrival end squeeze board is removed, takes out simulation core, observes remaining oil distribution.
