Description

Technical Field

[0001] This utility model relates to the field of logging detection, specifically an integrated system for logging sample detection and analysis. Background Technology

[0002] Well logging testing is primarily used for oil and gas resource assessment. This involves using various measuring instruments to analyze rock samples returned to the surface during oil and gas drilling operations to obtain real-time data reflecting various aspects of the well, including downhole geological structure, oil and gas content, and drilling procedures. Well logging testing typically involves multiple sample analyses. For example, patent CN1306147C discloses a comprehensive well logging system and method for petroleum geological exploration, which includes analytical equipment such as a chromatograph, fluorescence analyzer, and geochemical analyzer. Furthermore, samples require pretreatment processes such as grinding and compression before certain tests. In existing technologies, these processes are usually handled separately, and each process requires specialized operators, which increases labor costs and reduces testing efficiency.

[0038] like Figure 6 As shown, in this embodiment, the sampling substrate 503 is provided with a Y-direction limiting element 605 for limiting the displacement of the opening and closing mounting base 701 along the Y direction. The Y-direction limiting element 605 can be a suitable commercially available product such as a limit sensor as needed.

[0039] like Figure 5 As shown, in this embodiment, the gripper opening and closing drive assembly 7, in addition to the opening and closing mounting base 701, also includes a lead screw drive assembly, an opening and closing lead screw 706, and an opening and closing lead screw nut 704.

This utility model ensures sample delivery isolation by setting up the sample delivery chamber 3, thereby ensuring that the external environment will not affect the interior of the sample preparation chamber 1. In addition, the operator can enter the sample preparation chamber 1 by opening the first safety door 301 and the second safety door 306 in sequence.

[0050] like Figure 1 As shown in this embodiment, both the sample preparation room 1 and the automatic analysis room 2 are equipped with air conditioning to ensure that the indoor temperature meets the requirements. In addition, the automatic analysis room 2 is equipped with an analysis room observation window 207 to facilitate external personnel to observe the working status of the indoor equipment in real time.

[0051] The working principle of this utility model is as follows:

[0052] like Figures 1-3 As shown, this embodiment requires the preparation of 5 samples to meet the analytical and detection needs of different analytical devices. The specific working process is as follows:

[0053] 1. The operator opens the first safety door 301 and the second safety door 306 in sequence to enter the sample preparation room 1. In the external sample delivery room 302, the operator can perform corresponding operations such as putting on protective clothing and disinfection before opening the second safety door 306 to enter the sample preparation room 1.

[0054] 2. External personnel open the first safety door 301 of the sample delivery room 3 and enter the external sample delivery room 302. At this time, the second safety door 306 is closed. Then, the external personnel send the collected rock samples through the first isolation sample delivery window 303 into the isolation sample delivery room 304. After the sample delivery is completed, the external personnel exit and close the first safety door 301. Then, the operators in the sample preparation room 1 take the rock samples in the isolation sample delivery room 304 into the sample preparation room 1 through the second isolation sample delivery window 305.

[0055] III. The operators in sample preparation room 1 begin sample preparation work, specifically as follows:

[0056] The operator first places the rock sample into the logging rock sample observation instrument 104 for observation, and then uses the liquid preparation instrument 107 to prepare the required liquid reagent. After the reagent is prepared, it needs to be shaken evenly using the shaker 108.

[0057] After the liquid reagent is shaken well, the operator titrates the rock sample, then takes a picture of the rock sample for identification (this is a built-in function of the logging rock sample observation instrument 104), and finally selects samples as needed.

[0058] In this embodiment, five types of samples need to be selected for different tests, including:

[0059] Sample 1 is weighed and placed into a reagent bottle, which is then placed into the light hydrocarbon analyzer's feed tray.

[0060] Sample 2 was weighed and placed into a reagent bottle, which was then placed into the pyrolysis apparatus tray.

[0061] The sample was weighed and placed into a reagent bottle, which was then placed into the sample tray of the fractionation analyzer.

[0062] The sample was weighed and placed into a reagent bottle, which was then placed into the fluorometer tray.

[0063] Sample 5 is first dried in drying oven 106, then weighed and ground in grinder 110, then pressed by pressing machine 109, and finally placed in the elemental analyzer tray.

[0064] 4. After the sample preparation is completed, the identification strip printed by the barcode printer 111 can be affixed to the corresponding sample tray. Then, the sample tray is placed into the sample feeding section 401 of the sample feeding hopper 4 and placed on the corresponding layer's tray support plate 403. Then, the operator further pushes the sample tray along the tray support plate 403 of that layer and moves it into the sampling section 402 of the sample feeding hopper 4.

[0065] 5. The sampling mechanism 5 controls the movement of the sampling gripper 8 through the equipment program to pick up the sample trays in the sampling section 402 one by one and send them to the corresponding analysis equipment in the automatic analysis chamber 2.

[0066] When picking up the sample tray, such as Figures 5-6 As shown, this utility model utilizes the Z-axis lifting module 502 in the sampling mechanism 5, the Y-axis moving component 6 and the gripper opening and closing drive component 7 mounted on the sampling base plate 503 to ensure that the two sampling grippers 8 can meet the gripping and picking needs of sample trays of different types and specifications. The Z-axis lifting module 502 can adjust the height of the two sampling grippers 8 according to the height of the sample tray. The Y-axis moving component 6 can adjust the moving distance of the two sampling grippers 8 along the Y-axis according to the front and rear width of the sample tray. The gripper opening and closing drive component 7 can adjust the opening and closing degree of the two sampling grippers 8 according to the left and right width of the sample tray.
