摘要： A process for cementing a string of pipe in the permafrost region of a borehole of a well wherein aqueous drilling fluid actually used in drilling the wellbore in the permafrost region of a wellbore is employed. The drilling fluid contains or is adjusted to contain from about 2 to about 16 volume percent solids. Mixing with the drilling fluid (1) an additive selected from the group consisting of lignosulfonate, lignite, tannin, and mixtures thereof, (2) sufficient base to raise the pH of the drilling fluid into the range of from about 9 to about 12, and (3) cementitious material which will harden in from about 30 to about 40 hours at 40.degree. F. The resulting mixture is pumped into the permafrost region of a wellbore to be cemented and allowed to harden in the wellbore. There is also provided a process for treating an aqueous drilling fluid after it has been used in drilling the wellbore in permafrost, and a cementitious composition for cementing in a permafrost region of a wellbore.

摘要： A method of cementing in a wellbore penetrating subterranean formations characterized by employing a graded density spacer fluid intermediate a displacing fluid and a displaced fluid. This is particularly advantageous where a cement slurry is employed as displacing fluid to displace drilling fluid employed to drill a well penetrating subterranean formations. This alleviates problem with intermixing of the two fluids. This invention is doubly advantageous where a well contains both a substantially vertical portion and a substantially horizontal portion, since in the latter portion, the use of this invention enables controlling under-running or over-running of a displacing fluid with respect to a displaced fluid.

摘要： A composition for use in cementing a string of pipe or other apparatus in the permafrost region of a borehole of a well which composition is a dry cementitious mix which can be mixed with water on site for pumping into the wellbore and consists essentially of from about 40 to about 60 weight percent aluminate cement, from about 20 to about 30 weight percent alkaline earth metal sulfate, from about 10 to about 30 weight percent of at least one halide salt of an alkali metal and/or alkaline earth metal, from about 3 to about 8 weight percent attapulgite, from about 0.1 to about 1 weight percent of a mixture of at least one water soluble hydroxy carboxylic acid and a sulfoalkylated lignin, and from about 0.1 to about 1 weight percent of an alkali metal citrate.

摘要： A method for injecting fluid, such as an accelerator, into a wellbore comprises storing the fluid in a reservoir, locating the reservoir downhole in the wellbore, and then transferring the fluid from the reservoir into the wellbore. More particularly, one embodiment of the method comprises storing the fluid in a reservoir in a plug, pumping the plug down casing in a wellbore, and transferring the fluid at the bottom of the wellbore via a venturi effect. Another embodiment of the method comprises storing the fluid in a reservoir integrated into the wall of a portion of casing, setting the casing in the wellbore, and then transferring the fluid via a venturi effect from the reservoir into the annulus defined between the casing and the wellbore.

摘要： What is disclosed is a method of accelerating the set of a retarded cement. The cement may range from a drilling fluid containing dispersants or retarders that will slow down the set of the drilling fluid when cementitious fluid is added thereto, through overwashing, or treating a retarded primary or remedial cement that may have been injected into fractures or areas within a well to overwashing a plug or any volume of retarded cement that needs to be set in a well.The specific uses are discussed.

摘要： A squeeze silicate operation carried out through a coiled tubing for sealing upper perforations in a well casing to prevent flow of excess gas. A sodium silicate mixture is used which has a diverter material therein which rapidly builds a filter cake on the formation as the silicate is squeezed through the perforations. This filter cake forms a barrier which, in turn, prevents further flow of silicate into the formation. This effectively limits the depth of penetration of the silicate into the formation while still providing a good seal against flow through the squeezed perforations.
摘要翻译：挤压硅酸盐操作通过连续油管进行，用于密封井套管中的上穿孔以防止多余气体的流动。使用其中具有分流材料的硅酸钠混合物，其中当硅酸盐被挤压通过穿孔时，在该地层上快速地形成滤饼。该滤饼形成阻挡层，这又阻止硅酸盐进一步流入地层。这有效地限制了硅酸盐渗透到地层中的深度，同时仍然提供良好的密封以防止通过挤压穿孔的流动。
