Abstract
Заявленная группа изобретений относится к нефтегазодыбающей промышленности и может быть использована при проведении геофизических исследований в горизонтальных и наклонно-направленных действующих нефтяных скважинах. Техническим результатом группы изобретений является повышение точности измерения. Автономный скважинный резистивиметр-влагомер содержит блок питания, герметичный корпус, в верхней части которого расположен герметичный отсек, содержащий измерительную систему, а в нижней его части по оси корпуса расположено первое и второе сквозные окна овального сечения, образующие цилиндрические каналы. При этом между окнами внутри корпуса образован сквозной цилиндрический канал резистивиметра, содержащий датчик резистивиметра, выполненный в виде двух катушек и предназначенный для измерения электропроводности флюида в скважине. Причем во втором сквозном окне, находящемся выше первого, по оси корпуса расположен датчик влагомера, предназначенный для измерения влагосодержания флюида в скважине, при этом датчик влагомера снабжен датчиком температуры.The claimed group of inventions relates to the oil and gas industry and can be used when conducting geophysical surveys in horizontal and directional operating oil wells. The technical result of the group of inventions is to improve the measurement accuracy. The autonomous borehole resistivimeter-moisture meter contains a power unit, a sealed case, in the upper part of which there is a sealed compartment containing a measuring system, and in the lower part along the axis of the case there are first and second through windows of oval section, forming cylindrical channels. At the same time, a cylindrical through channel of a resistivity meter is formed between the windows inside the housing, which contains a resistivity sensor made in the form of two coils and designed to measure the electrical conductivity of the fluid in the well. Moreover, in the second through window, located above the first, along the axis of the housing there is a moisture meter sensor, designed to measure the moisture content of the fluid in the well, while the moisture meter sensor is equipped with a temperature sensor.
