Embodiment Construction

[0008] Below in conjunction with accompanying drawing and with best embodiment the present invention is described in detail:

[0009] refer to figure 1 with figure 2 , a high-temperature and high-pressure fluid component analysis sensor, which includes a main sealing body 7, a pair of light-transmitting left glass sheet 3 and a right glass sheet 8 installed in the main sealing body 7 and arranged parallel to each other, located on the outside of the right glass sheet 8 And light can be irradiated to the emission light source 13 on the right glass sheet 8, the receiving optical fiber 2 that is arranged on the outside of the left glass sheet 3 for receiving the light passing through; there is a closed space 14 for containing fluid between a pair of glass sheets , on the main sealing body 7 there is a fluid inlet 15 and a fluid outlet 16 communicating with the closed space 14 . The fluid outlet 16 is smaller than the fluid inlet 15 . In this way, a certain amount of fluid can...

Abstract

The invention relates to a high-temperature and high-pressure fluid component analysis sensor, which relates to a sensor, especially a sensor capable of monitoring fluid components. It includes a main sealing body, a pair of light-transmitting left glass sheets and a right glass sheet installed in the main sealing body and arranged parallel to each other, an emitting light source that is located on the outside of the left glass sheet and can irradiate light to the left glass sheet, and is arranged on the The outer side of the right glass sheet is used to receive the receiving optical fiber that passes through the light; there is a closed space for containing fluid between a pair of glass sheets, and a fluid inlet and a fluid outlet that communicate with the closed space are arranged on the main sealing body. The invention can measure the composition of the fluid through the spectrum transmitted by the optical fiber. The invention has the advantages of simple structure, good sealing performance and suitable for high temperature and high pressure environment. The device of the invention can detect the composition of downhole fluid at any time, and has the advantages of convenient and fast use.

Description

technical field [0001] The present invention relates to a sensor, in particular to a sensor capable of monitoring the composition of a fluid. Background technique [0002] In the oil field, the composition of the fluid in the oil well often changes, so it is often necessary to detect the composition of the downhole fluid at any time. The existing detection method is to sample the fluid and then go to the ground for detection. This detection method is cumbersome to operate, and it is impossible to grasp the change of the downhole fluid at any time. Chinese patent CN1376262A disclosed an "automatic etchant regeneration system with a high-precision sensor for monitoring etchant composition" on October 23, 2002. Although it has the function of composition monitoring, it is not suitable for underground high-temperature and high-pressure environments. use. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a high-...
