Problems solved by technology

Some companies use some soil installation methods, such as nailing the glass fiber reinforced plastic tank around it and putting it downhole to simulate different formations, and then put the logging instrument into the glass fiber reinforced plastic tank to measure the axial resolution of the logging tool. However, the disadvantage of this soil device and soil method is that due to reasons such as rusty nails and unbalanced radial media, the accuracy of this measuring device is not enough and the stability is poor

Embodiment Construction

[0020] As shown in Figure 1, the axial resolution measuring device in this embodiment includes a large tank body 1 with a circular column and a small tank body 2 with a circular column, and the small tank body 2 is stacked on the large tank body 1 , the inner cylindrical surface of the tank is formed as a through hole 16, the large tank is filled with saline, and the small tank is filled with a part of saline. The diameter of the large tank and the small tank are the same, and the height of the large tank is greater than the height of the small tank. The height of the large tank is restricted by the construction conditions. The bigger the better, considering the economy and flexibility, the weight of the large tank is 2 or 3 tons. The canister height is the largest thin layer size to be simulated.

[0021] The large tank and the small tank each have a circulation inlet and outlet. The large tank has a liquid inlet 11 for filling the tank with liquid, a sewage flange 12 for re...

Abstract

The invention relates to an axial resolution measuring apparatus and measuring system, the apparatus contains two circular ring column can bodies, the inner cylindrical surface of the can body is formed to a through-hole, the can body is folded vertically, electrolyte is full of in the can body folded in the lower, electrolyte is filled in the can body folded in the upper. The measuring system includes an induction log tool which is arranged in the measuring through hole and an axial resolution measuring apparatus. The measuring apparatus and measuring system of the invention can realize exact and continuous measurement of the axial resolution of the log tool, meanwhile realize coherence standardization of the log tool.

Description

technical field [0001] The invention relates to an axial resolution measuring device and a measuring system, in particular to an axial resolution measuring device and a measuring method of a well logging instrument. Background technique [0002] Strictly speaking, there is currently no accurate measuring device for the axial resolution of well logging tools in China. Some companies use some soil installation methods, such as nailing the glass fiber reinforced plastic tank around it and putting it downhole to simulate different formations, and then put the logging instrument into the glass fiber reinforced plastic tank to measure the axial resolution of the logging tool. However, the disadvantage of this soil device and soil method is that due to reasons such as rusty nails and unbalanced radial media, the accuracy of this measuring device is not enough and the stability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention...
