【 摘 要 】

Based onthe present condition of casing damage in the weak base asp flooding test area, combined with the analysis of the geological and engineering factors, it is concluded that the main causes of casing damage in the test area, including that the variation of ground stress caused by water absorption of the shale creepand dilation ofmud shale of old well area interferences to the new well, fault block, the interlayer or planarity pressure difference, the cementing quality and so on. According to the above-mentioned reasons, this article accordingly puts forward theprevention and treatment measures.
