Description
設置期間:平成13年8月23日〜平成14年9月11日(385日)
(2)テスト井B、設置深度1,790,7m(坑内温度135℃)
設置期間:平成15年10月28日〜平成16年1月28日(92日)
(1)、(2)の試験を行なった結果、可動シーリング部材に上側から大圧力が加わっても
該可動シーリング部材はピストン的に可動できるので、可動シーリング部材での坑井内流体の浸入を防止でき、円滑な連続計測が可能であることが確認できた。

Claims (4)
- 測定器ボディに連結される下部ヘッドボディと、検層ケーブルが導入される上部ヘッドボディとにより内部に閉鎖空間が形成されるヘッドボディを構成し、前記検層ケーブルの被覆ケーブルから導出した芯線が下部ヘッドボディに固定されたコネクタに接続されているケーブル接続ヘッドにおいて、
前記下部ヘッドボディ内には、坑内流体の浸入を防ぐ絶縁オイルを収容すると共に、この絶縁オイルが流出するのを防止する可動シーリング部材を設け、可動シーリング部材は、該シーリング部材の上下の圧力差によって該可動シーリング部材を軸方向に貫通する被覆ケーブルと一体に下部ヘッドボディ内を可動できる構成とし、
前記絶縁オイルは、坑内流体よりも比重の重い、比重1.0以上の低粘性絶縁オイルであるシリコンオイル又はフッ素系オイルであること
を特徴とするケーブル接続ヘッドの構造。 - 前記絶縁オイルは、動粘度150(20℃)以下のフッ素系オイルであること
を特徴とする請求項1記載のケーブル接続ヘッドの構造。 - 前記可動シーリング部材には、ヘッドボディの内面を摺動するOリングを嵌合していることを特徴とする請求項1又は2記載のケーブル接続ヘッドの構造。
- 前記可動シーリング部材の端部に内部を被覆ケーブルが貫通している筒状ブーツを固着し、該筒状ブーツがヘッドボディの内側に配設のスリーブの内周面を摺動するように構成したことを特徴とする請求項1〜3のうち何れか1項記載のケーブル接続ヘッドの構造。
