摘要： A method for reducing gas seepage into a cement slurry. The method includes adding a formulation to the cement slurry, the formulation comprising at least one component responsive to a predetermined concentration of hydrocarbon gas in the cement slurry, where upon the cement slurry reaching the predetermined concentration of hydrocarbon gas, the hydrocarbon gas undergoes at least a partial oxidation caused by the formulation to quicken the setting time of the cement slurry via release of heat by an exothermic reaction.

摘要： A process to prepare a solid cement composition; includes adding a meltable compound to an aqueous slurry of cement and; mixing until a homogeneous dispersion is obtained. The dispersion is placed in a mould, where the dispersion is set by hydration. Part of the meltable compound is melted at a temperature range of which the maximum is above the melting point of the meltable compound and a minimum below the melting point of the meltable compound. A material, either still as a dispersion or an already setting cement is exposed to heat development or a temperature gradient such that the temperature is at least above the congealing point of the meltable compound to obtain a solid cement composition.

摘要： A self-adaptive cement formulation includes cement, water and asphaltite-mineral particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self-healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.

摘要： A method of cementing a wellbore which penetrates a subsurface gas-containing formation is provided whereby gas migration is reduced. The method features the use of an additive consisting of a tannin backbone having grafted thereto at least two different vinylamide derivatives. The additive causes the cement slurry employed in the method to exhibit a Zero Gel Time of greater than about one hour, a Transition Time of less than about one hour and controls fluid loss from the slurry.

摘要： The present invention provides a method of preventing gas migration during primary well cementing. The method basically comprises the steps of displacing a cement slurry into the annulus between a string of pipe to be cemented in a well bore and the walls of the well bore, determining the initial surface pressure in the pipe after the cement slurry is placed in the annulus, displacing additional cement slurry into the annulus as is necessary to make up for losses in the surface pressure due to cement slurry gel strength development and volume reduction whereby the surface pressure is maintained substantially equal to the initial surface pressure until the cement slurry develops a predetermined gel strength sufficient by itself to prevent gas migration, and then allowing the cement slurry to set into a hard impermeable mass in the annulus.
摘要翻译：本发明提供一种防止一次井固井期间气体迁移的方法。该方法基本上包括以下步骤：将水泥泥浆置于井眼中要接合的一排管子与井筒壁之间的环形空间中，确定在将水泥浆料放置在井筒中之后管道中的初始表面压力环形，将额外的水泥泥浆置于环形空间中，这是必要的，以弥补由于水泥浆凝胶强度的发展和体积减小而导致的表面压力损失，由此表面压力保持基本上等于初始表面压力，直到水泥浆发生预定的凝胶强度自身足以防止气体迁移，然后允许水泥浆在环空中成为硬质不渗透物质。

摘要： A method of using a nanosilica-containing cement in a well cementing operation in a well, the method comprising the steps of pumping a nanosilica-containing cement formulation into the well, wherein the nanosilica-containing cement formulation comprises maltodextrin-coated nanosilica and a cement formulation, where the maltodextrin-coated nanosilica comprises nanosilica particles encapsulated by maltodextrin coating, wherein the pH of the nanosilica-containing cement formulation is between 9 and 14, maintaining a temperature in the well due to a temperature of a formation surrounding the well, wherein the disintegration of the maltodextrin coating is initiated due to the temperature and pH of the nanosilica-containing cement, exposing the nanosilica particles due to the disintegration of the maltodextrin coating from the maltodextrin-coated nanosilica, and reacting the nanosilica particles with the cement formulation such that the transition time is reduced.
