Abstract
The utility model relates to an oil and natural gas gas drilling technical field are devices of simulating the migration of gas drilling horizontal well hole enlargement section detritus, and it mainly comprises crossbeam, rigidity post, gas compressor, detritus injector, pressure sensor, temperature sensor, fixer, highspeed camera, gas -solid separator, intake pipe, outer tube, inner tube, outlet duct, hole enlargement section outer tube, monitor. Gas compressor can control and pour into the gaseous velocity of flow into, and the inner tube passes through the fixer to be fixed in the inside of outer tube, and detritus injector and intake -tube connection can directly pour into into. But through the gas compressor conditioning air velocity of flow, waiting the stable back of gas velocity, annotating the rock -entering bits through the detritus injector, the detritus gets into horizontal segment, hole enlargement section, the pipeline section of giving vent to anger under the drive of annular space air current, get into the gas -solid separator at last. And can follow the pressure sensor of outer tube, pressure, the temperature variation that temperature sensor can obtain different well sections to pass to the monitor with the change in valuel.

Background technology
Petroleum natural gas exploration cause of the gas horizontal well drilling with its unique advantage as China is made that weight
Contribute.Gas horizontal well drilling no doubt has many advantages, but the effect of hole cleaning quality of horizontal segment to down-hole in drilling process
Measurement, hole trajectory control affect larger.Due to the particularity of net horizontal section casing programme, it will usually produce expanding, cause ring
Migration path of the empty landwaste under various power comprehensive functions has significantly different with straight well section, in addition, and conventional drilling liquid phase ratio,
The large rock-carrying ability of gas is relatively weak so that the Cutting movement essence in gas horizontal well drilling extension diameter section there occurs change, landwaste
Easily bed is deposited in horizontal segment, so as to cause a series of engineering problem, such as high frictional resistance, high torque, bit freezing, logging tool enter
The problems such as well is difficult, setting of casing well cementation is difficult, cementing quality is poor, the quality of hole cleaning is directly connected to the success or failure of a bite well, therefore
A kind of device of gas drilling horizontal well extension diameter section Cutting movement is simulated to gas horizontal well drilling extension diameter section hole cleaning rule
Research has sizable engineering significance, and the popularization for gas horizontal well drilling technology and using particularly important.
The content of the invention
This utility model purpose is：A kind of device of simulation gas drilling horizontal well extension diameter section Cutting movement is provided.
The technical scheme that this utility model is adopted is：
This utility model simulates the device of gas drilling horizontal well extension diameter section Cutting movement, is mainly fixed by crossbeam, position
Post, gas compressor, landwaste infusion appliance, pressure transducer, temperature sensor, holder, high-speed camera, gas-solid separator,
Air inlet pipe, outer tube, inner tube, escape pipe, extension diameter section outer tube, monitor composition.Crossbeam and air inlet pipe and high-speed camera phase vicinal
In the top of whole device, high-speed camera can be moved left and right in crossbeam, can shoot extension diameter section with normal well section Cutting movement
Situation；Extension diameter section outer tube left part is provided with gas compressor, landwaste infusion appliance, position fixed column and pressure transducer, and right part is provided with
Temperature sensor, holder, escape pipe and gas-solid separator.Pressure transducer, temperature sensor can be with real-time monitoring extension diameter sections
The pressure and temperature of landwaste and gas, outer tube, extension diameter section outer tube are made using PVC transparent pipe.By gas compressor scalable
Air velocity, after stablizing etc. gas velocity, by landwaste infusion appliance landwaste is injected, and landwaste is entered under the drive of annular space air-flow
Horizontal segment, extension diameter section, outlet pipeline section, finally enter gas-solid separator.
Advantage of the present utility model：It is convenient to use, install, dismantle simple, good seal performance, here it is apparent that rock
Bits transport conditions, accomplish effectively to simulate gas drilling horizontal well extension diameter section Cutting movement.
