near wellbore formation damage

基本解释

The method of using mixture of HF and HCL to treat sandstone formations of remove formation damage near the wellbore is a widely used stimulation treatment.
使用土酸処理砂巖地層，解除井壁附近地層傷害，是廣泛採用的一種增産措施。
Hydraulic fracturing creates high-conductivity communication with a large area of formation and bypasses any damage that may exist in the near-wellbore area.
水力壓裂提供了與地層的一個大的區域的高傳導性連通，竝對在近井地帶可能存在的任何地層損害設置旁路。

Meanwhile, reverse imbibitions water blockage effect would be appeared to further damage the near the wellbore formation, especially in the low permeability and low productivity condensate gas wells.
同時，在近井帶還會形成反滲吸水鎖傚應，從而進一步加劇近井帶地層傷害，對低滲低産凝析氣井，這一現象尤爲嚴重。
