    摘要： High density, thermally stable, brine-based well fluids and methods of using the same are disclosed. In one embodiment a well fluid including water and a salt, the salt including at least one formate salt, wherein the weight-to-volume ratio of the well fluid is within the range of at least 120% to about 400% is disclosed. In another embodiment, a well fluid including water, a viscosifying agent, and a salt, the salt including at least one formate salt, wherein the weight-to-volume ratio of the well fluid is within the range of at least 120% to about 400% is disclosed. A method of treating a well using a well fluid, wherein the well fluid includes water and a salt, the salt including at least one formate salt, wherein the weight-to-volume ratio of the well fluid is within the range of at least 120% to about 400% is also disclosed.

    摘要： A method of injection of a higher density fluid into the top of the annulus of a well while lower density fluid is withdrawn from the top of the annulus of the well, wherein the higher density fluid has a composition such that it will drop through the lower density fluid without dispersing therein, thus flowing into the deeper reaches of the annulus and not short circuiting through the top of the annulus to the point from which the lower density fluid is intended to be withdrawn. A method of injection of a higher density fluid into the top of the annulus of a well without simultaneously withdrawing a lower density fluid from the top of the annulus of the well, wherein the higher density fluid has a composition such that it will drop through the lower density fluid without dispersing therein, thus flowing into the deeper reaches of the annulus so that when the pressure induced in the annulus as a result of this injection is subsequently bled off, principally the lower density fluid will be that which is withdrawn.

    摘要翻译： 将较高密度流体注入井的环空的顶部的方法，而较低密度的流体从井的环空的顶部排出，其中较高密度的流体具有这样的组成： 密度流体不分散在其中，因此流入环的更深的到达区域，并且不会通过环形空间的顶部短路到要从其中取出较低密度流体的点。 将较高密度流体注入井的环空的顶部的方法，而不从井的环空的顶部同时抽出较低密度的流体，其中较高密度的流体具有这样的组成： 较低密度的流体，而不会分散在其中，从而流入环的更深的深度，使得当由于该注入而在环空中引起的压力随后流出时，主要是较低密度的流体将被抽出。
