Description

Technical Field

[0001] This utility model relates to the field of petroleum testing technology, specifically to a rapid sampling and testing device for oilfield development. Background Technology

[0002] Rapid sampling and testing devices play a crucial role in oilfield development. These devices can quickly acquire oil, water, or gas samples on-site and rapidly perform operations such as component analysis and physical property determination, providing oilfield engineers with timely and accurate data support to optimize extraction plans, improve recovery rates, and ensure production safety. However, existing rapid sampling and testing devices for oilfield development are complex to operate, and traditional downhole sampling operations typically require several hours or even longer.

[0003] A search revealed a utility model patent with publication number CN213980783U, which discloses a rapid sampling and testing device for oilfield development, relating to the field of petroleum testing technology. Specifically, the device includes a sampling box and a belt. An electro-hydraulic rod is fixedly installed on the top of the sampling box, and the output end of the electro-hydraulic rod extends into the inner cavity of the sampling box and is fixedly connected to a push plate. This rapid sampling and testing device for oilfield development, through the coordinated use of a drive motor, a driving pulley, a belt, and a driven pulley, enables automatic movement of the sampling and testing device by the drive motor driving the moving wheels through the transmission between the driving pulley, belt, and driven pulley. This avoids the problem of traditional rapid sampling and testing devices for oilfield development requiring manual handling, and even some with added moving wheels still requiring manual pushing, which wastes physical effort, thus improving the practicality of this rapid sampling and testing device for oilfield development.

[0004] The aforementioned patent only uses a motor, oil pump, drill bit, and sampling rod to sample oil, which cannot fully perform preliminary processing and testing of the sample, thus hindering the efficiency and accuracy of subsequent testing.

[0005] Therefore, it is necessary to invent a rapid sampling and testing device for oilfield development to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rapid sampling and testing device for oilfield development. It integrates drilling, sampling, filtration, and preliminary processing through a motor, drill rod, turbine pump, filter, sampling tank, and ultrasonic mass homogenizer. It also utilizes high-precision sensors to perform preliminary testing on the samples, thereby solving the problem of reduced efficiency in existing technologies due to the inability to process and perform preliminary testing on samples.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid sampling and testing device for oilfield development, comprising a support plate, a housing fixedly connected to the upper end of the support plate, a hydraulic cylinder fixedly connected to the inner top wall of the housing, a connecting plate fixedly connected to the output end of the hydraulic cylinder, a motor fixedly connected to the upper end of the connecting plate, a gear one fixedly connected to the output end of the motor via a coupling, a chain sleeved on the outside of the gear one, a drill rod rotatably connected through the inside of the connecting plate, the drill rod rotatably connected through the inside of the support plate, a gear two fixedly connected to the side wall of the drill rod, and a chain sleeved on the gear two. Outside the second wheel, a turbine pump is fixedly connected to the upper end of the support plate. A telescopic tube is rotatably connected inside the drill rod, and the telescopic tube connects the inside of the drill rod to the input end of the turbine pump. A connecting pipe is fixedly connected to the output end of the turbine pump. A filter is detachably connected to the end of the connecting pipe, and the connecting pipe connects the output end of the turbine pump to the inside of the filter. A sampling tank is fixedly connected to the top wall of the inner shell, and the filter connects to the inside of the sampling tank. A connecting pipe is fixedly connected to the lower end of the sampling tank. A sampling tank is detachably connected to the upper end of the support plate, and the connecting pipe connects the inside of the sampling tank to the inside of the sampling tank.

[0008] Preferably, an ultrasonic homogenizer is fixedly connected to the inner wall of the shell, and the output end of the ultrasonic homogenizer is fixedly connected to the inside of the sampling container.

[0009] Preferably, a temperature sensor, a density sensor, and a moisture content sensor are fixedly connected through the interior of the second sampling container.

[0010] Preferably, a sampling door is fixedly connected to the side wall of the housing via a hinge, an observation glass is fixedly connected to the side wall of the sampling door, and a parameter display screen is fixedly connected to the side wall of the sampling door.

[0011] Preferably, a plurality of support columns are fixedly connected to the lower end of the support plate, and a universal wheel with brake is fixedly connected to the lower end of the plurality of support columns.

[0012] Preferably, a push rod is fixedly connected to the side wall of the support plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. When rapid oil sampling is required, the drive motor rotates, causing gear one to rotate. Under the action of the chain, gear one rotates, causing the drill rod to rotate. The hydraulic cylinder is activated, and the output end of the hydraulic cylinder slides downward, causing the connecting plate to slide downward, which in turn causes the drill rod to slide downward, allowing for deep sampling in the oil wellbore. The turbine pump is activated, and the turbine pump draws suction from inside the drill rod. The drill rod has a hollow structure inside, and the side wall has multiple openings and a filter screen. After the oil sample enters the telescopic pipe through the drill rod, it is pumped into connecting pipe one, then into the filter through connecting pipe one, and after filtration by the filter, it enters sampling tank one. The switch of connecting pipe two is opened, and the sample enters sampling tank two through connecting pipe two. After the sampling is completed, sampling tank two is removed, thus completing the rapid oil sampling.

[0015] 2. When the petroleum enters sampling tank one after being filtered by the filter, the ultrasonic homogenizer is activated. The high-frequency vibration generates a cavitation effect, which fully mixes the oil, water, and solid particles in the sample to form a uniform and stable suspension or emulsion, ensuring the representativeness and accuracy of subsequent tests. After the petroleum sample enters sampling tank two, the temperature sensor detects the temperature of the petroleum sample, the density sensor detects the density of the petroleum sample, and the water content sensor detects the water content of the petroleum sample. After sampling, the sample can be quickly and initially tested. The preliminary test parameters of the sample inside sampling tank two can be quickly viewed on the parameter display screen.

Turbine pump 301 is activated, sucking air from inside drill rod 204. The interior of 04 is hollow, and the side walls are equipped with multiple openings and filters.

[0032] The working principle of this utility model is as follows: When rapid oil sampling is required, the drive motor 201 is activated. Motor 201 is a servo motor, model MINAS. A6. The output of motor 201 rotates, driving gear 202 to rotate. Under the action of chain 203, gear 202 rotates, driving drill rod 204 to rotate. Hydraulic cylinder 206 is activated, and its output slides downward, causing connecting plate 207 to slide downward, which in turn drives drill rod 204 to slide downward, allowing for deep sampling of the oil wellbore. Turbine pump 301 is activated, pumping suction from inside drill rod 204. Drill rod 204 has a hollow internal structure with multiple openings and filters on its sidewalls. Oil samples enter telescopic pipe 302 through drill rod 204 and are then pumped into connecting pipe 303. After passing through connecting pipe 303, the samples enter filter 304 and then sampling tank 305. Connecting pipe 2 is then opened, allowing samples to enter sampling tank 2 307 through connecting pipe 2 306. After sampling, sampling tank 2 307 is removed, completing the rapid sampling of oil.

[0033] When the petroleum enters sampling tank 305 after being filtered by filter 304, the ultrasonic homogenizer 401 is activated. The high-frequency vibration generates a cavitation effect, which fully mixes the oil, water, and solid particles in the sample to form a uniform and stable suspension or emulsion, ensuring the representativeness and accuracy of subsequent tests. After the petroleum sample enters sampling tank 307, the temperature sensor 402 detects the temperature of the petroleum sample, the density sensor 403 detects the density of the petroleum sample, and the water content sensor 404 detects the water content of the petroleum sample. After sampling, the sample can be quickly and initially tested. The preliminary test parameters of the sample inside sampling tank 307 can be quickly viewed on the parameter display screen 104.
