A centered image reservoir parameter measurement tool

Abstract

The invention discloses a center type imaging reservoir parameter measuring tool, comprising a connector integrated in a measuring tool framework and an upper connector integrated in the measuring tool framework. The side, near the connector, of the measuring tool framework is provided with a circuit board framework, and the circuit board framework is embedded with a circuit board; the side, nearthe upper connector, of the measuring tool framework is provided with an imaging measurement sensor; and during operation, the data measured by the imaging measurement sensor is transmitted to the circuit board in the circuit board frame, and the circuit board receives the data transmitted by the imaging measurement sensor and measures engineering parameters. The imaging reservoir parameter measuring tool is integrated with a sector positioning unit and a sodium iodide crystal sensor, through a fixed algorithm, the surface angle of a gravity tool can be reversely performed, a sector position of the sensor under the rotating state can be judged in real time, a goal of rotating to measure the stratum azimuth gamma is achieved, and the edge detection function is achieved.

Description

technical field [0001] The invention relates to the technical field of oil drilling downhole testing, in particular to an imaging reservoir parameter measurement tool. Background technique [0002] At present, in the geosteering of ultra-thin reservoirs, the traditional natural gamma ray measurement system is used to measure the gamma value of the whole bottom layer around the wellbore, so as to judge the entry and exit of the drilling tool into the reservoir; however, the distance between the traditional measurement system and the drill bit It is far away and the edge detection function cannot be realized. In addition, traditional measuring instruments only use a sodium iodide crystal sensor, which does not have the ability to measure sectors. [0003] After a long period of practice, it is not difficult to find that the measurement system in the prior art has a relatively limited detection capability due to the lack of sector-by-sector detection capability, and cannot accu...

[0003] After a long period of practice, it is not difficult to find that the detection ability of the existing measurement system is limited due to the lack of sector detection ability, and it is impossible to accurately adjust the drilling direction of the drill bit in real time.
