摘要： A weighting agent for use in a wellbore fluid composition is provided. The weighting agent includes a ferrosilicon material, wherein iron is present in the ferrosilicon material in an amount equal to or greater than about 50% by weight of the ferrosilicon material. A composition including a wellbore fluid and a weighting agent, as well as methods for using and making a weighting agent, are also provided.

摘要： A vibration isolator for use between a support structure and a roller thrust bearing including a first race, a second race, a bearing cage and at least one roller element. The vibration isolator includes a radially extending portion with a mating surface, a bearing surface, an inner peripheral edge and an outer peripheral edge, the radially extending portion being substantially disk-shaped. An annular flange extends axially from one of the inner peripheral edge and the outer peripheral edge of the radially extending portion, and at least one groove is defined by the mating surface of the radially extending portion. The bearing surface is configured to abut one of the first race and the second race and the mating surface is configured to abut the support structure such that a void is defined between the at least one groove and the support structure.
摘要翻译：一种用于支撑结构和滚子推力轴承之间的隔振器，包括第一座圈，第二座圈，轴承座和至少一个滚子元件。隔振器包括具有配合表面的径向延伸部分，支承表面，内周边缘和外周边缘，径向延伸部分基本上为圆盘状。环形凸缘从径向延伸部分的内周边缘和外周边缘之一轴向延伸，并且至少一个凹槽由径向延伸部分的配合表面限定。支承表面构造成邻接第一座圈和第二座圈中的一个，并且配合表面构造成邻接支撑结构，使得在至少一个槽和支撑结构之间限定空隙。
