…Physical logging is particularly important for investigating oil-bearing reservoirs, and it can be said that physical logging developed alongside the oil mining industry. Physical logging technology dates back to 1927, when the French Schlumberger brothers Conrad and Marcel Schlumberger used a pair of electrodes to measure the vertical distribution of the resistivity and natural potential of the formations in a borehole. These later came to be called electrical logging and SP logging, but in principle they correspond to the resistivity method and natural potential method, which are types of geophysical exploration, respectively. … *Some of the terminology that mentions "Schlumberger, M." is listed below.

…石油を含む油層を調べるための物理検層は,とくに重要で,物理検層は石油鉱業とともに育ったといえる。物理検層の技術は1927年にさかのぼり,フランスのシュランベルジェ兄弟Conrad Schlumberger,Marcel Schlumbergerはひと組の電極対で坑井中の地層比抵抗,自然電位の垂直分布を測定した。その後これらは電気検層,SP検層と呼ばれるようになったが,原理的にはそれぞれ物理探査の一つである比抵抗法,自然電位法に相当する。… ※「Schlumberger,M.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
