Description
Technical field
the utility model relates to the utensil of oilfield wellhead full-page proof, specifically a kind of oil well head bulk sample extracting apparatus.
Background technology
in oil field development manufacturing process, getting the analysis of full-page proof analysis data by oil well, is a kind of important means of Reservoir behavior being carried out to complete analysis.The mode that full-page proof got by current oil well has two kinds, and one is adopt bucket to put into wherein by oil-water mixture at well head from sample cock, and then fish for crude oil, put in blow-down pit by remaining profit and reclaim, this mode labour intensity is large; Another kind imports in blow-down pit by produced liquid in oil well, from blow-down pit, fish for crude oil, and this mode crude oil that is easy and other oil well mixes, and the data error of admission is large, has had a strong impact on the accuracy of oil field analysis.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil well head bulk sample extracting apparatus.
the utility model is realized by following technical proposals:
oil well head bulk sample extracting apparatus, comprising: handwheel, center-pole, piston, sealing ring, upper cover, cylindrical shell, emptying valve, blow-down pipe, outlet, outlet valve, support, clamp, bolt, inlet tube.Described oil well head bulk sample extracting apparatus piston is flexibly connected with center-pole, be provided with externally threaded center-pole to be connected with the screwed hole of centre of upper cover and to pass through, center-pole upper end is provided with handwheel, upper cover is connected with cylindrical shell threaded upper ends, piston is encapsulated in cylindrical shell, the top of cylindrical shell is provided with blow-down pipe, blow-down pipe is provided with emptying valve, be provided with support in opposite directions, support is provided with half clamp, and second half clamp is upper and lower to be bolted, and bottom surface is provided with outlet, outlet is provided with outlet valve, and lower end is provided with inlet tube.
piston in above-mentioned oil well head bulk sample extracting apparatus is provided with 1 ~ 2 road cannelure, and cannelure is built with sealing ring.
inlet tube in above-mentioned oil well head bulk sample extracting apparatus is provided with the non-sharp anti-slip veins of zigzag.
the beneficial effects of the utility model are: be applicable to oil well head bulk sample extracting, and residual crude oil and sewage can be avoided the environment polluted, reduce the labour intensity of oil recovery workman, admission oil sample is accurately and reliably, significant for oil field reservoir performance analysis.
Accompanying drawing explanation
fig. 1-the utility model master looks complete section structural representation.
in figure, 1. handwheel, 2. center-pole, 3. piston, 4. sealing ring, 5. go up box nut, 6. cylindrical shell, 7. emptying valve, 8. emptying head, 9. outlet, 10. outlet valve, and 11. support, 12. clamps, 13. bolts, 14. inlet tubes, 15. anti-slip veins.
Detailed description of the invention
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
oil well head bulk sample extracting apparatus is made up of handwheel 1, center-pole 2, piston 3, sealing ring 4, upper cover 5, cylindrical shell 6, emptying valve 7, blow-down pipe 8, outlet 9, outlet valve 10, support 11, clamp 12, bolt 13, inlet tube 14.The piston 3 of described oil well head bulk sample extracting apparatus is flexibly connected with center-pole 2, be provided with externally threaded center-pole 2 to be connected with the screwed hole of centre of upper cover 5 and to pass through, handwheel 1 is equipped with in center-pole 2 upper end, upper cover 5 is connected with cylindrical shell 6 threaded upper ends, the piston 3 that one sealing ring 4 is housed is encapsulated in cylindrical shell 6, the top of cylindrical shell 6 is provided with blow-down pipe 8, emptying valve 7 blow-down pipe 8 is equipped with, be provided with support 11 in opposite directions, support on 11 and be welded with half clamp 12, on second half clamp 12, under connected by bolt 13, bottom surface is provided with outlet 9, outlet valve 10 outlet 9 is equipped with, lower end is provided with inlet tube 14, inlet tube 14 is provided with the non-sharp anti-slip veins 15 of zigzag.
method of operating: first, clamp 12 is connected on the transverse tube of Well head flow path, piston 3 is risen to the top of cylindrical shell 6, closes outlet valve 10, opens emptying valve 7; Secondly, with sebific duct, inlet tube 14 is connected with well mouth sampling valve; 3rd, open sample cock, the oil gas water mixed liquid of oil well output enters cylindrical shell 6, be full of after cylindrical shell 6 until liquid and close emptying valve 7, rotating handwheel 1 drives center-pole 2 to be moved down by piston 3, bottom sedimentation water is back in crude oil flow process, after determining to move down distance according to the water status of oil well, jigger lifting piston 3 again, open emptying valve 7, repeat aforesaid operations, until after the crude oil in cylindrical shell 6 reaches requirement, crude oil is drained into sample bucket from outlet valve 10, moves down piston 3 and unnecessary liquid is expressed in crude oil flow process.
