[0040] 1. Experimental comparison: In order to understand the performance of the Raman laser gas analyzer more intuitively, the present invention was tested and compared with Shanghai Shenkai 3Q04 chromatogram, see Table 1.
[0041] Table 1 Comparison between Raman gas analyzer and 3Q04 chromatographic performance indoor experiment
[0042]
[0043] 2. On-site comparison test:
[0044] Test method: Simultaneously, the present invention and 3Q04 chromatograph perform on-site mud logging operations, and oil and gas monitoring is carried out throughout the process. Basic data of the test well: Well Xinsha X, well type: horizontal well, test well section: 0-3168.00m, test time: 61 days, Raman gas analysis interpreted a total of 22 layers of oil and gas shows, oil and gas show well sections, interpretation layers Consistent with 3Q04 chromatogram. See image 3 , 4 , 5.
[0045] 3. Practical comparison
[0046] ①Raman analyzer has less auxiliary equipment, low failure rate ...
