Description
掘削泥水は主として2つのグループに分けられる。すなわち、油性泥水(一般に油相中に海水が逆エマルション化したもの)と水性泥水とに分けられる。
Hemphill T.,Campos W.,およびPilehvari A.:「降伏性法則モデルは泥水レオロジーをより正確に予測する」石油ガス雑誌91、No.34、8月23日、1993年、45〜50頁
(a)水性および/または有機の液体ベース、
(b)上記液体ベース中で懸濁状態にある単位体積当たりの質量が少なくとも2g/cm3、好ましくは少なくとも4g/cm3の少なくとも一種の粒子の形をした増量剤、
(c)平均直径が10〜30nmで、比表面積が200〜250m2/gであるカーボンナノチューブ。
これらのナノチューブは、本発明の掘削流体に混和する前に、精製および/または酸化および/または粉砕することができる。
本発明の一実施例では、NTCは唯一の増粘剤である。すなわち、掘削流体は基本的にその他の任意の周知な増粘剤、例えば上記特許文献1(欧州特許第1,634,938号公報)に記載のような有機ポリマー、脂肪酸、クレーまたは界面活性剤および電解質をベースにした増粘剤系は含まない。掘削流体中のNTCの濃度はこの場合はかなり高く、好ましくは1〜3重量%、特に1.5〜3重量%のNTCである。
本発明の別の対象は、水性および/または有機の液体ベースと、平均直径が10〜30nmであるカーボンナノチューブとを含む掘削流体を注入し、掘削流体のカーボンナノチューブ含有量を掘削深度、掘削温度および/または掘削圧力が増加するのに応じて増加させることを含む、地下岩層の掘削方法にある。この掘削方法では、少なくとも一種の増量剤および/またはカーボンナノチューブ以外の少なくとも一種の増粘剤を掘削流体に導入するのが好ましい。
以下、本発明の実施例を示す。本発明は下記の実施例の説明からより良く理解できよう。しかし、下記実施例は単に説明のためのもので、本発明の範囲を限定するものではなく、本発明は添付の請求の範囲によってのみ限定されるものである。
180℃で16時間または40時間の動的にエージング(vieillissement)し、次いで205℃で60時間または120時間の静的に沈降試験を行った時の試験泥水の粘度を50℃、170s-1の剪断で測定した。
「沈降」とは一般に角度のある掘削孔で見られる増量剤の粒子のアバランシェ効果を意味し、掘削孔底部の増量剤の濃度が過剰になった時に沈殿効果によって掘削孔頂部の濃度が不足する現象を意味する。沈降試験は底部の泥水サンプルの密度D1を測定して行なった。この試験の前にこのサンプルを45°傾いたセル中に所定の時間、所定の温度に保持しておいた。下記式を用いて沈降指数ISを演繹した:IS=D1/2×Do(ここで、Doはサンプルの初期密度)。
[図1]からわかるように、NTCの添加によってサンプルのレオロジーが全体的に改善される。[図2]からさらに、NTCの添加によって重晶石の沈降の防止が容易になることがわかる。沈降指数(または「沈下係数」)は60時間後の0.59とは対照的に0.56、120時間後の0.66とは対照的に0.58である。
この実施例から、NTCは高温で粘度増加剤として油性泥水に使用できることがわかる。掘削泥水中で用いる通常の増量剤を、NTCを用いて懸濁状態に維持することもできる。
