摘要： A high-alumina cement composition is disclosed which has thermal stability over a wide temperature range and which develops strength at an early age. The cement composition comprises a high-alumina cement, a halide salt and calcium sulfate. This composition when added to water provides a hydraulic cement composition which can be employed in environments subject to wide temperature fluctuations below and above freezing (e.g. 32.degree. F).

摘要： A method of well completion is provided which enables much of the well casing to be later recovered from the well in the event the well is later abandoned, or where intermediate casing must be run during drilling of the well but may later be removed when the liner is in place. The well is completed by any of several embodiments of manipulative steps, leaving the lower portion of the annulus filled with a conventional cementitious material and the upper portion of the annulus filled with an aqueous gel comprising effective quantities of water, a water soluble alkali metal silicate, and a water soluble metal compound capable of releasing a multivalent metal cation to react with the water soluble silicate. An economically significant portion of the casing can thereafter be recovered if necessary after first severing the casing above that portion adjacent the set cementitious material. Where an intermediate string of casing is employed only to facilitate drilling the remainder of the well, the cement may be omitted with respect to the intermediate string as is known in the art.
摘要翻译：提供了一种完井的方法，其可以在井稍后被废弃的情况下或者在井的钻井期间必须运行中间套管的情况下随后从井中回收井的大部分井，但是当衬管到位通过操作步骤的几个实施例中的任何一个完成井，留下环状物的下部填充有常规水泥质材料，并且填充有水凝胶的环空的上部，其包含有效量的水，水溶性碱金属硅酸盐，以及能够释放多价金属阳离子与水溶性硅酸盐反应的水溶性金属化合物。之后，如果需要，首先将套管切断在靠近凝固水泥材料的部分上方，则可以回收经济上重要的套管部分。在仅使用中间套管套筒以便于钻井的其余部分的情况下，如本领域已知的那样，可以相对于中间管柱省略水泥。
