[0002] Petroleum is a viscous, dark brown liquid and a primary target for geological exploration, often referred to as the "blood of industry." Petroleum reserves exist in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons.

[0003] Once an oil field is discovered, its development begins. The history of oil field development can be traced back to the early 20th century, and oil field development equipment has also gone through a process of development from scratch, from importation to independent research and development. With the development of oil fields, oil field development equipment is constantly being innovated and updated.

[0004] my country's petroleum industry is increasingly emphasizing the authenticity and reliability of oil and gas samples from exploration and development wells. Obtaining first-hand, authentic, and effective oil and gas sample data is crucial for the exploitation of oil and gas resources.

[0005] The main function of a sampler is to retrieve formation fluids at a fixed depth during well testing and other downhole operations, obtain their fluid properties through analysis, and then formulate subsequent work measures. However, traditional mechanical samplers and existing electronic samplers are not convenient, intelligent, and generally have poor high-temperature resistance. Utility Model Content

[0010] Furthermore, the rear of the sampling controller slide (3) is provided with a non-closed cylindrical cavity.

[0011] Furthermore, the control head (8) has a threaded rear end of the through hole.

[0012] The beneficial effects of this utility model are as follows: the sampling controller of this utility model is resistant to high temperature, accurate and reliable, has a short sample tube, good sealing performance, convenient connection, strong real-time performance, and uses a threaded quick connection method, which greatly simplifies the operation process and improves the sampling success rate.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1 An embodiment of this application shows a sampling controller, which includes a sampling controller body 1 and a sampling controller outer cylinder 2, with the outer cylinder 2 sleeved on the outside of the sampling controller body 1;

[0020] The sampling controller body 1 includes a sampling controller slide cylinder 3, steel balls 4, a hanging sleeve 5, a control rod 6, an unlocking sleeve 7, a control head 8, and a conversion connector 9. The sampling controller slide cylinder 3 is located at the front end of the sampling controller body 1. The hanging sleeve 5 is movably connected to the rear of the sampling controller slide cylinder 3. The front part of the hanging sleeve 5 is embedded inside the sampling controller slide cylinder 3. Several steel balls 4 are arranged between the sampling controller slide cylinder 3 and the hanging sleeve 5. The unlocking sleeve 7 is snapped onto the rear of the hanging sleeve 5. The unlocking sleeve 7 is embedded at the rear of the hanging sleeve 5. The control head 8 is movably connected to the rear of the unlocking sleeve 7. The unlocking sleeve 7 is embedded at the front of the control head 8. The conversion connector 9 is snapped onto the rear of the control head 8. The conversion connector 9 is embedded at the rear of the control head 8. The hanging sleeve 5, control rod 6, unlocking sleeve 7, control head 8, and conversion connector 9 are provided with a through hole that matches the control rod 6. The control rod 6 is set in the through hole.

[0021] The rear of the sampling controller slide 3 is provided with a non-closed cylindrical cavity, and the rear of the through hole of the control head 8 is provided with a thread.

[0022] The sampling controller is controlled by a card remover. During use, the sample is slowly lowered to the target layer. The sampling delay time is set via the instrument's software. The card remover starts timing according to the set time. Once the time is up, the DC motor starts moving, driving the lead screw to move the control rod 6 of the sampling controller upwards. The steel ball 4 moves inwards to the bottom of the control rod, and the sampling controller's slide cylinder 3 is pulled upwards. Simultaneously, the internal mechanism closes, completing the sampling. After the sampling time is up, the sample should be left to stand for a certain period to ensure it enters the sample cylinder intact. The sampler is then retrieved, the sample is removed, and sealed. Sampling is now complete.

[0023] In summary, this utility model provides a sampling controller that is high temperature resistant, accurate and reliable, with a short sample tube, good sealing performance, convenient connection, and strong real-time performance. Furthermore, the use of a threaded quick connection method greatly simplifies the operation process and improves the sampling success rate.
