Description

TECHNICAL FIELD

[0001] The application belongs to the field of oilfield development, and particularly relates to an oil well sample bucket splash-proof sampling shield device. BACKGROUND

[0002] In the process of oilfield development, in order to timely understand the production situation of an oil well, the water content of the oil well must be tracked in a timely and accurate manner, and therefore the oil well needs to be sampled and analyzed frequently. The water content of the oil well can be directly understood through oil well sampling, and the change of liquid production and oil production of the oil well can be accurately mastered, thereby providing a reliable basis for oil-water well dynamic analysis, and being the first-hand information indispensable for oilfield development.

[0003] Since the oil liquid in the wellhead production pipeline of the oil production well has a certain pressure, and oil and gas are not separated during sampling, especially for wells with large gas volume and high pressure, during the sampling process, the instantaneous release of pressure will cause the oil and gas liquid to impact the emptying bucket and the sampling bucket, thereby causing splashing, and the existing daily sampling means can easily pollute the wellhead environment and personnel, and cause inaccurate sampling information.

[0004] The existing solutions mainly include two kinds, one is the oil and gas separation mode, and the other is the deceleration and buffering mode. Due to the limitation of the field environment, whether it is oil and gas separation or deceleration and buffering, the device is large, the structure is complex, it is not easy to observe during the operation process, and the device is not convenient to clean after sampling.

It should be understood that the specific embodiments described herein are intended to explain the relevant application, but not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0022] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] As shown in Figs. 1-3 The present application provides an oil well sample barrel splash-proof sampling shield device, which comprises:

[0024] The connecting ring 1 is circularly arranged and adapted to the sample barrel.

[0025] a sampling port 2 is formed on the upper edge of the connecting ring 1;

[0026] a visible splash-proof cover 3 is fixedly connected to one end of the connecting ring 1, and an exhaust hole is formed in the other end, and the outer diameter of the visible splash-proof cover 3 decreases along the axial direction.

[0027] In specific implementation, the visible splash-proof cover 3 is conical and is an umbrella-shaped transparent cover with a small upper end and a large lower end. The connecting ring 1 is fixedly connected to the sample barrel by buckling or threading. When oil and gas contact the sample barrel body and cause splashing, the splashing oil is blocked by the visible splash-proof cover 3 and flows back to the sample barrel, so as not to pollute the operators and equipment. Meanwhile, the visible splash-proof cover 3 is made of transparent material, and the liquid level of the sample barrel can be observed through the visible splash-proof cover 3. The sampling work is successfully completed while avoiding splashing, and the problem of environmental pollution is avoided.

[0028] In some embodiments, the sampling port 2 is rectangular.

[0029] In specific implementation, the sampling port 2 is a square hole, and the square hole is a square slot with a diameter of 20-40 mm formed downward along the upper edge of the ring, which facilitates the sampling and emptying of the sampling valve.

[0030] In some embodiments, the diameter of the exhaust hole formed in the end of the visible splash-proof cover 3 is 20-30 mm.

[0031] In specific implementation, a 20-30 mm channel is formed in the upper part of the umbrella-shaped body of the visible splash-proof cover 3, which facilitates the discharge of gas.

[0032] During sampling operation, the oil well sample barrel splash-proof sampling cover device is fixedly connected to the sample barrel body through the connecting ring 1, the sampling and emptying head of the sampling valve is placed in the device through the device sampling port 2, and the sampling valve is opened for sampling. The device is applied to the sampling process. When oil and gas contact the sample barrel body and cause splashing, the splashing oil is blocked by the visible splash-proof cover 3 and flows back to the sample barrel, so as not to pollute the operators and equipment. Meanwhile, the liquid level of the sample barrel can be observed through the visible splash-proof cover, and the sampling work is successfully completed while avoiding splashing, which meets the field implementation conditions and has the advantages of low cost, safe use, small size, light weight, and convenient and fast operation, and can effectively avoid the splashing pollution caused by sampling operation.
