Optimization Study On The Drainage Gas Recovery Technology Of The Gas Wells With Accumulated Fluid

With the continuous development and utilization of gas, gas formation pressure and capacity gradually declined gradually increased low-yielding inefficient wells, drainage and gas wells difficulty increases, gas output in the production process if the water can not be discharged, will accumulate at the bottom, causing severe flooding shut down wells, while water-rich gas blocks in the production process due to the larger water production, some can not be discharged fluid production wells, gas wells can also cause flooding discontinued. To solve effusion drainage and gas wells problems, the need for carrying liquid gas critical flow simulation, by optimizing the foaming agent, optimize gas drainage and gas systems, the introduction of new drainage gas recovery technology, the establishment of a suitable fluid water drainage and gas wells supporting technology, timely restoration of normal production wells, gas wells to ensure normal functioning. To this end,"effusion drainage and gas wells Optimization of gas well development of the entire field has important practical significance.
