near wellbore formation damage

基本解釋

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.
使用土酸處理砂巖地層，解除井壁附近地層傷害，是廣泛采用的一種增產(chǎn)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(gè)大的區(qū)域的高傳導(dǎo)性連通，并對(duì)在近井地帶可能存在的任何地層損害設(shè)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(shí)，在近井帶還會(huì)形成反滲吸水鎖效應(yīng)，從而進(jìn)一步加劇近井帶地層傷害，對(duì)低滲低產(chǎn)凝析氣井，這一現(xiàn)象尤為嚴(yán)重。
