Description
Technical field
It is real the utility model discloses sand screen net erosion degree after a kind of Lab-evaluation simulated formation temperature Gas well dewatering
Experiment device.
Background technology
In gas exploitation course, because bottom water immerses gas-bearing formation, output of the gas well in production with dampening is caused,
There is air water conjunction to adopt.And it is very big to stratum intensity effect after formation water output, formation strength can be substantially reduced, causes the skeleton on stratum
Sand is peeled off, and becomes free sand, and free sand enters near wellbore zone under the carrying of high velocity air, will ultimately result in formation sand production.
In deep water gas field, gas well yield is high, and gas flow rate is very big, reservoir sand under the carrying of high velocity air will to screen casing and oil pipe and
Ground oil-gas facility causes serious infringement, and the inwall of screen casing, oil pipe and ground oil-gas facility will be gradually thinning, final to occur
Thorn leakage, this will bring huge disaster to the exploitation in deep water gas field, and deep water gas field is because the depth of water is more than 1000 meters, once occur
The leakage of screen casing thorn or Tubing, well workover difficulty is very big, and workover cost is high, and the success rate of well workover is low, therefore, deep water gas
