摘要： A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects.
摘要翻译：在地下位置的封闭空间的压力补偿系统通过盐在水中的热诱导溶解度变化改变体积。盐保持在刚性或不渗透性，柔性或多孔和柔性的外壳中。同样条件变化和温度升高，一些盐进入溶液，由此导致的体积减小，其补偿由于钻孔中的温度升高引起的热诱导体积增加。相反，钻孔温度的降低会使一些盐溶液溶解，以增加体积，以抵消相邻流体的体积减少，以保持压力稳定在封闭体积中。在多孔外壳的实施例中，开口足够小以便甚至在溶液中保留盐。然而，由于热效应的变化，预计压力补偿的最小净流量。
