| 摘 要： | 盐膏层蠕变有瞬态、稳态和加速度蠕变3个阶段。对于石油工程．盐膏层蠕变主要表现为瞬态蠕变和稳态蠕变。在大量现场盐膏层岩心力学试验的基础上，对盐膏层的蠕变进行了研究，分析了稳态蠕变规律，提出了稳态蠕变三维分析方程，为更准确地计算蠕变压力，合理设计套管程序和钻井液密度奠定了基础。

| Abstract: | Three distinct stages of salt creeps are temporary, steady and accelerated creeps. The temporary creep and stable creep are the main kinds of salt creeps during petroleum engineering. On the basis of large numbers of mechanics tests on core samples obtained from salt beds, the development of salt creep is analyzed, and the three-dimensional equations are also derived. The equations lay foundations to calculate creep pressures accurately and to design casing and mud density reasonably. |
