为了科学地开发地下能源,采集地层资料为开发设计提供依据,必须在钻井过程中进行取心。在盐岩层取心,盐溶是影响取心收获率的关键。正常循环的泥浆温度(井口为地面温度,井下为地层温度)是往复变化的,所以盐溶和重结晶是不可避免的。油基类泥浆能解决盐溶问题,但成本高,所以应用受到限制。采用饱和盐水泥浆成本较低,抑制盐溶能力较强, In order to develop underground energy scientifically, collecting the stratum data provides the basis for the development and design and must be coring in the drilling process. Coring in the salt rock, salt solution is the key to the coring rate. Normal circulation of mud temperature (wellhead surface temperature, downhole formation temperature) is reciprocating changes, so salt and recrystallization is inevitable. Oil-based mud can solve the salt problem, but the cost is high, so the application is limited. The use of saturated salt slurry lower cost, strong ability to inhibit salt dissolution,
