摘要
分析了巨厚盐膏层在复杂的压力系统及高温高压下发生塑性蠕动、井径缩小,易发生埋钻、卡钻、下套管困难等严重复杂情况;探讨了盐膏层钻井有关承压堵漏、钻盐膏层的钻井液、钻盐膏层随钻扩孔、盐膏层井径稳态蠕变率测定工艺等问题。
Analysis on plastic wriggle, reduction of well diameter, bit burying, bit jamming and being difficult for casing etc. under complicated pressure system and high pressure of the extremely thick layer. Load bearing and blocking, drilling fluid, underreaming while drilling, determination to ratio of stable wriggle in drilling in salty layer are studied.
