Abstract
Description
「掘削流体」は、ベネズエラのインベテップ(INVETEP)から得られる商標つきの非水性流体である。
「FC−100」は、FC−100FLUORADブランド(Brand)フルオロケミカル界面活性剤としてミネソタ州セントポールのスリーエム・カンパニー(3M Company(St.Paul,MN))から入手できるフルオロアルキルスルホネート系界面活性剤組成物である。
「FC−740」は、FC−740FLUORADブランド(Brand)井戸刺激添加剤としてスリーエム・カンパニー(3M Company)から入手できるフルオロ脂肪族高分子エステル系界面活性剤組成物である。
30gのヘプタン中で混合しながら25.20グラム(g)のトリス(2−メトキシエトキシ)ビニルシラン(ウィスコンシン州ミルウォーキーのアルドリッチ・ケミカル(Aldrich Chemical Co.(Milwaukee,WI)))と20.00gのヘプタメチルジシロキサン(ペンシルバニア州タリータウンのゲレスト(Gelest,Inc.(Tullytown,PA)))を組み合わせることによりヘプタメチル(2−[トリス(2−メトキシエトキシ)シリル]エチル)トリシロキサンカップリング剤(「シランカップリング剤A」)を調製した。白金(0)ジビニルテトラメチルジシロキサン触媒(米国特許第3,814,730号明細書の手順により調製されたもの)の一滴を0.3gのヘプタンに添加して溶液を形成させた。この溶液0.1gを上の反応混合物に添加し、その後、一晩加熱しないで窒素雰囲気中で攪拌した。赤外線分光分析(IR)を用いてSi−Hピークの消失によって決定される終了まで反応は続いた。減圧下での蒸発によってヘプタンを組成物から除去して、シランカップリング剤Aを生じさせた。
シランカップリング剤Aで表面改質されたシリカナノ粒子を次の通り調製した。5nmの平均粒度および約600m2/gの表面積(製造業者であるイリノイ州ナパービルのナルコ・ケミカル(Nalco Chemical Co.(Naperville,IL))によって報告されたもの)を有する固形物15重量%のアンモニア安定化コロイドシリカである200gのナルコ(NALCO)2326、37.38gのシランカップリング剤Aおよび388gの1−メトキシ−2−プロパノール(アルドリッチ・ケミカル(Aldrich Chemical Company)を1ガロンのガラスジャー内で混合しながら組み合わせた。混合物を含むジャーを密封し、排気されたオーブンに入れ、80℃で一晩加熱した。その後、混合物を乾燥用の蒸発皿に移送し、150℃でフロースルーオーブン内で乾燥させて、24.65gの白色粒状固形物を生じさせた。
攪拌しながら、丸底フラスコ内で50.02gのトリエチレングリコールモノメチルエーテルと46gのメチルエチルケトンを組み合わせることによりN−(3−トリエトキシシリルプロピル)メトキシエトキシエチルカルバメート(PEG3TES)を調製した。3−(トリエトキシシリル)プロピルイソシアネート(76.03g)を混合物に添加し、混合した。ジブチルジラウレート(約3mg)を混合物に添加し、混合物を約16時間にわたり攪拌した。メチルエチルケトンの大部分を約70℃の温度でロータリーエバポレータで減圧で除去した。追加のトリエチレングリコールモノメチルエーテル(0.1g)を混合物に添加して、IR分光分析によって検出された残りのイソシアネートと反応させた。
ナルコ(NALCO)2326(15g)、PEG3TES(92.29g)および脱イオン水(16.88g、18メグオーム)をフラスコに添加し、手で振とうした。混合物を80℃オーブン内で一晩(約18時間)加熱して、約11.5重量%の固形物を有するゾルを形成させた。
発泡させるべき溶液5gを秤量して、30mLの微細ガラス濾過器付きフラスコに供給した。ガラス濾過器は、4〜5.5マイクロメートルの孔サイズを有していた。ガラス濾過器から頂上までのフラスコの高さは約15cmであった。5psiの一定指示圧力でフリットを通して窒素ガスを吹かせた。「発泡時間」は、泡がフラスコの頂上を溢流するのに要した時間または5分のどちらか最初に起きた方であり、気体がフリットを通して流れ始める時間から測定される。「最終泡高さ」は、泡がフラスコを溢流しなかった場合、5分後の泡の高さ(cm)である。「泡崩壊時間」は、窒素ガスを止めた点から空気/液/フラスコ界面基準で泡バブルの連続環がもうなかった時間である。
2質量%の粒子Aを掘削流体に添加し、組成物を上述した方法により発泡させた。比較例1および2は掘削流体中に2質量%のFC100およびFC740を含んでおり、上述したように比較例1および2を試験した。各サンプの「泡高さ」、「発泡時間」および「泡崩壊時間」を測定した。試験の結果を表1において下で示している。
粒子Bをそれぞれ0.01、0.1、0.5、1.0および1.3重量%の量で水に添加し、組成物を上述した方法により発泡させた。比較例3〜5は、脱イオン水中に0.1質量%のFC−100(CE−3)、0.5質量%のFC−100(CE−4)および0.5質量%のFC−740(CE−5)を含んでいた。比較例も上述した方法により発泡させた。サンプルごとの発泡試験の結果を表2において下で示している。
ペムレン(PEMULEN)1621(1g)(ノベオン(Noveon)製)、18MΩミリポア(Millipore)水(499g)およびトリエタノールアミン(中和剤)5滴を含有する水性原液(25℃で密度1g/mL)を調製した。水の代わりにディーゼル油を用いたことを除き、上のように非水性原液を調製した。この溶液の密度は0.814g/mLであった。
