Description
Technical field
The utility model belongs to oil and gas and goes out sand control field, is specifically related to a kind of gas well and goes out in sand control simulated experiment containing sand gas receipts sand device.
Background technology
Sand production of oil-gas wells is one of major issue of running into of oil exploitation, and gas well problem of shaking out is particularly remarkable.If sand evil can not get administering, gas well shakes out can be more and more serious, causes the gas well that shakes out effectively not develop.The harm main manifestations shaked out is three aspects: reduce or stop production operation, ground and underground equipment abrasion, casing failure and oil well are scrapped.The sand control of gas well is seemed particularly important, mechanical sand control is current relatively more conventional anti-sand method, and the key of mechanical sand control is to select rational sand-proof pipe, this will go out sand control experiment at laboratory simulation gas well, to eventually pass through sand-proof pipe filter after gas in sand body carry out analyzing and processing, contrast different preventing sandpipe is to the sand controlling result on this stratum, find out the sand-proof pipe that sand controlling result is best, this will weigh to the sand body filtered in rear gas, the sorting of order level, and the condition of first carrying completing this step is exactly the sand body will collected to greatest extent in gas.Through in many ways investigating, at present for this receipts sand device also imperfection containing sand gas, be placed with in the bucket of clear water by directly passing into one containing sand gas mostly, the shortcoming of this kind of device existence is:
(1) though can collect a part of sand body, can produce bubble and discharge after gas enters water body, cause little grade sand body discharge with bubble and cannot be caught by water body absorption, this produces very big error to the analysis of final experimental data;
(2) scene cannot simultaneously gas-monitoring flow and directly carry out sorting by order number to the sand body collected.
Therefore, need to develop and a kind ofly can collect containing the sand body device in sand gas to greatest extent, go out the sand sample collection of sand control simulated experiment for indoor gas well.
Summary of the invention
The purpose of this utility model is: provide a kind of sand sample harvester for indoor gas well goes out sand control simulated experiment, collect the sand body containing sand gas to greatest extent, the accuracy of final experimental data can be ensured like this, can directly press the sorting of order number to the sand sample collected simultaneously, and the flow of gas after receipts sand is detected.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of gas well goes out in sand control simulated experiment receives sand device containing sand gas, the feature of this receipts sand device is, top is cylinder, bottom is inverted cone, described receipts sand device is followed successively by flow meter from top to bottom, upper base gland, atomizer, air inlet port, observation port, sand sample multipass sort device, described flow meter contains filter disc, further filtration sand body, the erosion reducing a small amount of sand body flow meter in gas damages, flow meter is monitored gas flow after desanding, be fixedly connected with bolt between described upper base gland with receipts sand device sidewall and contain sealed loop-pad, described atomizer is positioned at above air inlet port, the water smoke of ejection can catch the remaining sand body in gas, described observation port energy Real-Time Monitoring SEA LEVEL VARIATION, described air inlet port bottom outlet is positioned at 2cm above waterline, make gas from gas outlet out after speed reduce rapidly and impact the water surface, increase the contact surface containing sand gas and water, form certain water smoke simultaneously, make to form water smoke above the tank body water surface, further seizure sand body, described sand sample multipass sort device is positioned at tank body bottom, by the requirement of order number, horse back sorting is carried out to sand sample, save time.
The beneficial effects of the utility model:
As can be seen from above-mentioned technical scheme, a kind of gas well that the utility model provides goes out in sand control simulated experiment receives sand device containing sand gas, and this device can be collected to greatest extent containing the sand body in sand gas, and principle is simple, easy to operate, meets requirement of experiment.
