Abstract
The utility model relates to a double-swirl crude oil degassing and sampling collector which is used for preventing oil gas from splashing in the sampling work of the processes of oil gas production, gathering and transportation. The double-swirl crude oil degassing and sampling collector comprises a liquid inlet pipe and a liquid collecting barrel, wherein the upper end of the liquid collecting barrel is provided with a gas outlet, and the lower end of the liquid collecting barrel is provided with a liquid collecting hole; the liquid inlet pipe is communicated with the liquid collecting barrel by a double-tangential connecting pipe; the liquid collecting barrel is a spindle-shaped barrel which is narrow in the lower part and wide in the upper part; a demisting mesh screen is arranged at the upper part of the barrel; and oil-gas mixed liquid sprayed out from a sampling valve can form double swirls in the barrel, so that natural gas is prevented from escaping, and the crude oil is prevented from being splashed. The oil-gas two-phase mixed liquid can be rapidly separated, and the double-swirl inlet liquid can be formed by the double-tangential connecting pipe, so that the oil and the gas can be fully mixed together, and the subsequent test of sampling is not influenced. The double-swirl crude oil degassing and sampling collector is small in volume, light in weight, convenient to install and suitable for collecting and testing multiple fluids.
Description
Technical field
The utility model relates to the crude oil sampling device of petroleum industry, and particularly crude oil bispin stream degassing sampling collector in the sampling work of production of hydrocarbons and the defeated process of collection, prevents the oil gas splash.
Background technology
Present marine crude oil production well contains a large amount of associated gases mostly, the gas output of well head is higher, and this crude oil sampling work to production tree and external transport pipeline has brought a lot of inconvenience, particularly causes the crude oil splash easily when sampling, the sulfide hydrogen natural gas is overflowed, and causes environmental pollution and personal injury.There is above-mentioned problem equally in land gassiness producing well.For the sampling method of gassiness oil well, generally be to use drum to be put in open flow under the sample cock earlier at present, after the stream of the liquid in the sample cock is stable, re-uses sampler barrel and receive the back chemical examination that not only operation inconvenience, and contaminated environment are unfavorable for health of human body.The production scene need be produced and is suitable for producing actual degassing sampling collector, prevents natural gas effusion and crude oil splash, makes things convenient for the carrying out of sampling work.
Summary of the invention
The purpose of this utility model is to make crude oil bispin stream degassing sampling collector, prevent to open sample cock after natural gas overflow and the crude oil splash, be convenient to the carrying out of crude oil sampling work, protect environment.
The utility model is achieved in that crude oil bispin stream degassing sampling collector comprises feed tube and liquid collecting cylindrical shell, and liquid collecting cylindrical shell upper end is the gas outlet, and the lower end is the liquid collecting mouth, and feed tube is communicated with the liquid collecting cylindrical shell by the two inlets tube connector.The liquid collecting cylindrical shell is the spindle cylindrical shell, and is following narrow wide, is provided with the demist mesh screen at an upper portion thereof in the cylindrical shell.The oil gas mixed liquor that sprays from sample cock can form bispin stream in cylindrical shell, prevent natural gas effusion and crude oil splash.
The beneficial effects of the utility model are as follows: the utility model is made according to the operation principle of spiral-flow type gas-liquid separator, utilize gas-liquid two-phase after tangential direction enters the liquid collecting cylindrical shell, to make circular motion, drop is finally separated from gas because heavier being subjected to throws on the inwall of spindle cylindrical shell than big centrifugal force.And gas is overflowed along with the gas outlet that rotary speed reduces finally to move upward from the top gradually, and liquid then flows out from the liquid collecting mouth of bottom, and crude oil is outgased fast.Its major advantage is:
1, separation oil and gas two-phase mixed liquor apace.
2, form bispin by the two inlets tube connector and flow to liquid, guaranteed that oil gas fully mixes, do not influence the follow-up chemical examination of sampling.
3, volume is little, and light weight is convenient to install.
4, avoided the splash of oil gas.
5, be suitable for the collection chemical examination of multiple fluid.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of two inlets tube connector.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, referring to Fig. 1 and Fig. 2.Crude oil bispin stream degassing sampling collector comprises feed tube 6 and liquid collecting cylindrical shell 1, and liquid collecting cylindrical shell 1 upper end is gas outlet 5, and the lower end is a liquid collecting mouth 3, and feed tube 6 is communicated with liquid collecting cylindrical shell 1 by two inlets tube connector 2.Liquid collecting cylindrical shell 1 is the spindle cylindrical shell, narrowly widely down, is provided with demist mesh screen 4 at an upper portion thereof in the cylindrical shell, with the profit detention in the oil gas mixed liquor in the cylindrical shell of bottom.Two inlets tube connector 2 is Y-pieces, and an end is communicated with feed tube 6, and the other end is communicated with liquid collecting cylindrical shell 1 by two inlets.When opening sample cock, high-pressure oil gas mixed liquor in the well enters liquid collecting cylindrical shell 1 from two inlets of two inlets tube connector 2, in its spindle cylindrical shell, form bispin stream, oil-water mixture wherein flows out from liquid collecting mouth 3, gas then passes through the further separation of demist mesh screen 4, emerges from gas outlet 5.Feed tube 6 outboard end are provided with screw thread and are connected with sample cock.When the utility model be connected with sample cock on well head or the gathering line finish after; below this device, place drum and collect the liquid that flows out when opening; after the stream of the liquid in the sample cock is stable; receive crude oil sample with sampler barrel again; when having protected environment, guaranteed the safety of sampling work.
