Abstract (en)
[origin: US4802359A] The invention relates to a tool for measuring pressure in the annular space lying between casing and the production string of an oil well. The tool comprises two sliding elements, with the first element being temporarily locked in a section of the string constituting a circulating valve and with the second element carrying a pressure sensor which receives the pressure reigning in the annular space via a duct and orifices of the circulating valve after they have been brought into register.
Abstract (fr)
L'invention concerne un outil permettant de mesurer la pression dans l'espace annulaire (15) compris entre le cuvelage (10) et la colonne de production (11) d'un puits de pétrole. L'outil est composé de deux éléments coulissants (1, 2), dont le premier élément (1) est v errouillé temporairement dans une section de la colonne (11) formant vanne de circulation (SSD) et dont le deuxième élément porte un capteur de pression (31) recevant, via un conduit (35) et les orifices (22, 23), mis en regard, de la vanne de circulation, la pression régnant dans l'espace annulaire (15).
