Abstract:
(EN) A novel composition which contributes to reducing costs and to shortening processes and which can contribute to improving production efficiency, a composition for a downhole tool, a degradable rubber member for a downhole tool, a downhole tool, and a well drilling method are provided. This composition contains a degradable rubber and a decomposition accelerator, and, as the aforementioned decomposition accelerator, contains 0.1-20 parts by mass of at least one type of compound represented by general formula (I) per 100 parts by mass of the degradable rubber; this downhole tool composition contains said composition; the degradable rubber member for a downhole tool, and a downhole tool are provided; and the well drilling method makes use of these. (In expression (I), R1 and R2 are independently a phenyl group or an alkyl group of 1-5 carbon atoms.)
(FR) La présente invention concerne une nouvelle composition qui contribue à réduire les coûts et à raccourcir les procédés et qui peut contribuer à améliorer l’efficacité de production, une composition pour outil de fond de puits, un élément en caoutchouc dégradable pour outil de fond de puits, un outil de fond de puits, et un procédé de forage de puits. Cette composition contient un caoutchouc dégradable et un accélérateur de décomposition, lequel accélérateur de décomposition contient de 0,1 à 20 parties en masse d’au moins un type de composé représenté par la formule générale (I) pour 100 parties en masse du caoutchouc dégradable ; cette composition d’outil de fond de puits contient ladite composition ; l’élément en caoutchouc dégradable pour un outil de fond de puits, et un outil de fond de puits sont fournis ; et le procédé de forage de puits les utilise. (Dans l’expression (I), R1 et R2 sont indépendamment un groupe phényle ou un groupe alkyle contenant de 1 à 5 atomes de carbone.)
(JA) 経費軽減や工程短縮に寄与し、生産効率の向上に寄与できる新規な組成物、ダウンホールツール用組成物、ダウンホールツール用分解性ゴム部材、ダウンホールツール、及び坑井掘削方法を提供する。分解性ゴム及び分解促進剤を含み、上記分解促進剤として、下記一般式(I)で表される化合物のうちの少なくとも1種類を、上記分解性ゴム100質量部に対して0.1~20質量部にて含有する組成物、並びに当該組成物を含む、ダウンホールツール用組成物、ダウンホールツール用分解性ゴム部材、ダウンホールツール、及びそれらを用いた坑井掘削方法。(式(I)中、R及びRはそれぞれ独立に、炭素数1~5のアルキル基又はフェニル基である)
