摘要： Provided are compositions and methods of using a liquid suspension of hollow particles comprising a plurality of hollow particles, water, a suspending aid, and a stabilizer selected from the group consisting of a non-ionic surfactant, a latex, an oleaginous fluid, porous silica, and combinations thereof. The liquid suspension is homogenous. An example method includes statically storing the liquid suspension in a container for at least one week; wherein the liquid suspension maintains a difference in density from the top of the container to the bottom of the container of less than one pound per gallon while stored. The method further includes adding the liquid suspension to a treatment fluid; wherein the liquid suspension reduces the density of the treatment fluid; and introducing the treatment fluid into a wellbore penetrating a subterranean formation.

摘要： Systems and methods related to preparing foamed cement for laboratory analysis are provided. A prepared cement slurry is placed in a cement reservoir cell configured to pressurize the cement slurry contained within the cement reservoir cell to a capture pressure. After pressurization, the cement slurry and a compressed gas are introduced into a foam generator. Foamed cement generated in the foam generator is introduced from the tee into a foam capture cell where it can cure prior to analysis.
摘要翻译：提供了与制备用于实验室分析的发泡水泥有关的系统和方法。将制备的水泥浆料放置在水泥蓄积池中，该水泥蓄积池被配置成将包含在水泥蓄存池中的水泥浆加压至捕集压力。加压后，将水泥浆和压缩气体引入泡沫发生器。泡沫发生器中产生的泡沫水泥从三通中引入泡沫捕集池，在分析前它可以固化。
