Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] When assembling the tester, first connect the sensors and output signal lines one by one, and then put multiple sensors into the sensor assembly; each output signal line passes through the sensor signal channel and connects to the fixed frequency transmitter and data collector 5. The other end of the fixed-frequency transmitter and data collector is sequentially connected to the natural gamma ray detector 6, the magnetic positioning 7, and the power supply system 8 to form the core part, which is embedded in the pressure-bearing protective shell 12, and the pressure-bearing protective shell 12 The port of the sensor assembly is connected to the signal channel 11 of the sensor assembly, sealed with a copper ring, the other end of the sensor assembly is connected to the dryness measurement assembly 2, and the other end of the water-containing electrode as...

Abstract

The invention discloses a tester for testing six or five or four or three parameters of a steam injection profile including downhole steam flow, dryness, downhole temperatures, pressure, magnetic localization and natural gamma in the oil field heavy oil well heating power mining technology, a test system and a test method. The six-parameter combination tester is formed by sequentially connecting a guide flow type rotor wing wheel flow meter assembly (1), a dryness measuring assembly (2), a machine core and an isotope detection assembly (9) through threads. The machine core is mainly formed by connecting a temperature sensor (3), a pressure sensor (4), a fixed-frequency emission and data acquisition unit (5), a natural gamma detector (6), a magnetic locator (7) and a power supply system (8) in sequence. The six-parameter combination tester has the advantages of being high in precision, capable of calibrating the depth, more accurate in test data, more comprehensive in test item, wider in adaptability, novel and capable of being applied to air injection and steam injection mining new techniques.

Description

technical field [0001] The invention relates to a six-parameter combination tester in the thermal recovery process of heavy oil wells in oil fields, in particular to a six-parameter combination test for measuring steam injection profiles, including downhole steam flow, dryness, downhole temperature, pressure, magnetic positioning and natural gamma instrument. Background technique [0002] With the rapid development of electronic technology, the existing logging instruments can no longer meet the current testing requirements, and a new type of combined testing instrument with more accurate testing data, more comprehensive testing items and wider adaptability is needed. Contents of the invention [0003] The purpose of the present invention is to solve the test problems of downhole temperature, pressure, steam flow, dryness, magnetic positioning and natural gamma of thermal recovery wells, so as to overcome the deficiencies of traditional test techniques. The instrument ado...
