Description
Известные устройства дл каротаиха скважпн по метолу скольз щих контактов обладают тем недостатком, что против пластов, обладающих плохой электропроводностью, показани станов тс нечеткнми п точное определение границ таких пластов затруднено. Это об1, сн етс тем. что значительна часть тока лз нзлюрите.льного электрода ответвл етс в буровой раствор скважнпы.The known devices for drilling borehole by the method of sliding contacts have the disadvantage that against formations with poor electrical conductivity, the readings become unclear and accurate determination of the boundaries of such formations is difficult. This is about, which is a significant part of the current of the current electrode electrode is branched off into the drilling mud well.
Предлагаемое устро1гство устран ет этот недостаток HpHiieHoinicM экранного ко.лы1;а, окружаюн1,его )нтельньп1 э.. нотенцна.С которого равен нотенцна.лу электро;иь чего ллипн ориентируютс в направленн стенки скважины.The proposed arrangement eliminates this drawback of the HpHiieHoinicM on-screen co. 1; and, surrounding it, 1) on the phone. This is the notification. With which is equal to the notification of the electro, and what is oriented in the wellbore wall.
Устройство изображено на чертеже н состоит нз корпуса 1 снар да, опускаемого в скважнну, на котором с немощью нру/кины 2 укрен.лен точечный и.чмернтельньпг электрод 3, окружонны экранным кольцевым электродом 4. Провода о н 6 кабел , i;a -;отором снар д онускаетс в скважнну, подключен к одному п тому же лолюсу батареи, или другому источнику посто нного тока, расположенному на новерхностн.The device shown in the drawing is composed of a shell 1 of a projectile lowered into a well, on which, with the infirmity of a duct / kina 2, a pinpoint electrode axis 3 is located, circumferentially surrounded by a screen ring electrode 4. Cables of an n 6 cable, i; By removing the projectile on the well, it is connected to one of the same battery pole, or another DC source located on the surface.
