Abstract

The cement composition contains a latex and a stabiliser for this latex. It additionally contains a silica flour which allows it to be applicable even above 110 DEG C and up to the degradation temperature of the polymer (for example approximately 270 DEG C). Application to deep oil wells and in the geothermal field.

Description

Compositions de ciments pour cimentation de puits permettant de lutter contre le cheminement de gaz sous pression dans l'annulaire cimenté. Cement compositions for the cementing of wells for combating the path of pressurized gas in the cemented ring.

Le brevet principal décrit des compositions de laitiers de ciments pour cimentation de puits pétroliers > inhibant le cheminement du gaz sous pression dans l'annulaire cimenté et améliorant de plus les propriétés du ciment. Ces compositions contiennent un@ciment, un latex, un stabilisant du latex et.de 11 eau et sont applicables jusqulâ des températures de l'ordre de 1000C.  The main patent discloses cement slurry compositions for cementing oil wells> inhibiting the flow of pressurized gas into the cemented annulus and further improving the properties of the cement. These compositions contain a cement, a latex, a latex stabilizer and water and are applicable up to temperatures of the order of 1000C.

La présente invention concerne des compositions utilisables dans le même but mais a des températures allant de 108-112 C a la température de début de dégradation du latex. The present invention relates to compositions usable for the same purpose but at temperatures ranging from 108-112 C at the onset of degradation of the latex.

Pour que le domaine d'application couvre des températures aussi élevées, il a été découvert qu'il était nécessaire d'incorporer, an plus des quatre constituants principaux (ciment, latex, stabilisant du latex, eau), une farine de silice dont il est essentiel que la répartition granulométrique soit similaire a celle de la poudre de ciment utilisée afin que la silice n'intervienne pas sur la quantité de latex nécessaire pour empocher le cheminement de gaz. So that the scope of application covers such high temperatures, it has been discovered that it is necessary to incorporate, in addition to the four main constituents (cement, latex, latex stabilizer, water), a silica flour which it It is essential that the particle size distribution be similar to that of the cement powder used so that the silica does not interfere with the amount of latex necessary to pocket the gas flow.

La présente invention concerne donc la combinaison de cinq constituants essentiels : ciment, latex, stabilisant du latex, farine de silice, eau, comme compositions de laitiers de ciment pour la cimentation des puits pétroliers, permettant d'inhiber le cheminement du gaz sous pression jusqu'a des températures pouvant atteindra 270 C-300 C environ, température de début de dégradation (sous la pression atmosphérique, dans l!air) des principaux latex utilisés selon le brevet principal. The present invention therefore relates to the combination of five essential constituents: cement, latex, latex stabilizer, silica flour, water, as cementitious cement compositions for the cementing of oil wells, for inhibiting the path of the gas under pressure up to at temperatures up to about 270 ° C-300 ° C, the onset temperature of degradation (at atmospheric pressure, in air) of the main latices used according to the main patent.

Selon l'invention, on incorporera - de 20 à 50% en poids de farine de silice par rapport au ciment,
de préférence 30 a 35%; de de 20 S 30% en poids de latex par rapport au ciment; de de 3 a 15% en poids de stabilisant du latex par rapport au latex.According to the invention, there will be incorporated - from 20 to 50% by weight of silica flour relative to the cement,
preferably 30 to 35%; from 20% to 30% by weight of latex relative to the cement; from 3 to 15% by weight of latex stabilizer relative to the latex.

Pour les définitions et caractéristiques des ciments, latex et stabilisants pouvant etre utilisés, on se reportera au brevet principal pages 3 a 6 notamment,
Les compositions selon l'invention pourront également contenir les additifs classiques rappelés page 7 du brevet principal, tels qu'agents anti-mousse, retardateurs de prise, accélérateurs, allégeants, alourdissants, etc.For definitions and characteristics of cements, latex and stabilizers that can be used, reference is made to the main patent pages 3 to 6 in particular,
The compositions according to the invention may also contain the conventional additives mentioned on page 7 of the main patent, such as defoaming agents, retarders, accelerators, lighteners, weighting agents, etc.

On indiquait dans le brevet principal qu'il était déjà surprenant de pouvoir travailler h 850C, a fortiori sans cheminement de gaz, car les compositions usuelles n'étaient pas efficaces audelà de 50 C environ. Il est encore plus surprenant de pouvoir travailler entre environ 110 C et, par exemple, 27000
Les exemples suivants illustrent l'invention sans toutefois en limiter la portée.It was stated in the main patent that it was already surprising to be able to work at 850.degree. C., especially without gas flow, since the usual compositions were not effective above about 50.degree. It is even more surprising to be able to work between about 110 C and, for example, 27000
The following examples illustrate the invention without, however, limiting its scope.

Dans ces exemples, on a utilisé la cellule pour essai de cheminement de gaz décrite dans le brevet principal notamment page 9 et figure 5. In these examples, the gas flow test cell described in the main patent was used, in particular on page 9 and FIG.

Les conditions d'essai sont les suivantes - température : 130 et 160 C - pression en tette des deux cellules : 40 bars - contrepression dans la cellule DP : 20 bars - on permet l'écoulement gazeux lorsque la pression dans les pores
du ciment atteint 18 bars, clest-d-dire diminue de 40 a 18 bars.The test conditions are as follows: - temperature: 130 and 160 ° C. - pressure of the two cells: 40 bars - counterpressure in the DP cell: 20 bars - the gas flow is allowed when the pressure in the pores
cement reaches 18 bar, ie decreases from 40 to 18 bar.

L'agent anti-mousse utilise dans les exemples est un polyglycol. The antifoam agent used in the examples is a polyglycol.

La répartition granulométrique de la farine de silice utilisée est par ailleurs la suivante
< 100 : 100 %
< 50 : 90 W
< 20 p : 45 % < 10 : : 23 %
< 5 : 8 %
Le tableau ci-après rassemble les principaux résultats de ces essais. The particle size distribution of the silica flour used is also the following
<100: 100%
<50: 90 W
<20 p: 45% <10: 23%
<5: 8%
The table below summarizes the main results of these tests.

Conclusion principale
Un laitier de ciment classique ne contenant pas de latex
(exemple 1) conduit a un débit très élevé de cheminement de gaz, ce
qui correspond une absence de caractéristique d'inhibition du
cheminement du gaz. Au contraire, un laitier de ciment contenant la quan
tite adéquate de latex, de stabilisant et de silice conduit à un débit
de gaz nul, que ce soit a une température de 130 C ou a une tempé
rature de 1600C,. ce -qui correspond à une excellente caractéristique
d'inhibition du cheminement'du gaz (exemples 2 et 3, selon l'invention).Main conclusion
A conventional cement slag not containing latex
(Example 1) leads to a very high flow rate of gas flow, which
which corresponds to an absence of inhibition characteristic of the
gas flow. On the contrary, a cement slurry containing the quan
adequate titration of latex, stabilizer and silica leads to
zero gas, whether it is at a temperature of 130 C or at a temperature of
height of 1600C ,. which corresponds to an excellent characteristic
gas flow inhibition (Examples 2 and 3, according to the invention).

De plus, des analyses thermogravimétriques et thermodif
férentielles ont permis de montrer que le latex préconisé dans
l'invention. polsstyrène-butadiène contenant de 70 a 30% en poids de styrène et de 30 a 70% en poids de butadiène, ne commence- a se dégrader sous l@effet de la température qu'à partir de 2700C.Les autres constituants entrant dans la composition de ciment décrite dans l'invention d savoir ciment, stabilisant et eau, n'étant pas dégradés par l'effet de température, au moins jusqu'a une température de 3000C, il apparat que l'invention est également applicable à des températures supérieures à 1600C, la limite supérieure d'application étant fixée par la température de dégradation du latex utilisé, en l'occurrence 2700C.In addition, thermogravimetric and thermodynamic analyzes
have shown that the latex recommended in
the invention. Polystyrene-butadiene containing from 70 to 30% by weight of styrene and from 30 to 70% by weight of butadiene, does not begin to degrade under the effect of the temperature until from 2700 C. The other constituents entering the cement composition described in the invention namely cement, stabilizer and water, not being degraded by the effect of temperature, at least up to a temperature of 3000C, it appears that the invention is also applicable to temperatures higher than 1600C, the upper limit of application being fixed by the degradation temperature of the latex used, in this case 2700C.

De telles températures permettent de traiter efficacement des puits profonds et meme des puits de forage géothermique.  Such temperatures can effectively treat deep wells and even geothermal wells.
