Fluid column is smoothly established in sky, and the kill-job mud of injection is not blown out by air-flow, gas-bearing formation pushed down within the most fast time, while to the greatest extent may be used
Can injury of the ground reduction to reservoir.At present, without a gas drilling kill-job laboratory apparatus, therefore, there is provided herein a kind of big
Type gas drilling kill-job analogue means, this experimental provision either size or function all can more true simulation gas drillings
Well Killing Process, it is easy to observe, flow pattern, bottom pressure, gas production etc. in the reacting gas drilling well Well Killing Process of clear and definite
The change of parameter, reliable laboratory reference is provided for real gas drilling well kill-job operation, is easy to preferred arrangement and method for construction.
