Fig. 3 is fluid control apparatus structural representation.
In figure: 1-box cupling; 2-protects pressure ring; 3-fluid control apparatus; 4-connects pressure ring; 5-outer jointing jacket; 6-filtration beds; 7-internal protective cover; 8-base tube; Pressure ring is connected under 9-; 10-top pressure ring; 11-valve plate; 12-spring; 13-bellmouth valve seat.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
As Figure 1-3, horizontal well liquid current control sand control screen, box cupling 1 is connected with base tube 8 by screw thread; Fluid control apparatus 3 is connected with base tube by screw thread, and is covered by upper protection pressure ring 2; Upper protection pressure ring one end is welded with base tube, the other end with on be connected pressure ring 4 and weld; Outer jointing jacket 5, filtration beds 6, internal protective cover 7 are coated on base tube from outside to inside successively, the two ends of outer jointing jacket, filtration beds, internal protective cover respectively with on be connected pressure ring and lower connection pressure ring 9 welds; The lower connection pressure ring other end welds with base tube; Top pressure ring 10 is connected with bellmouth valve seat 13 by screw thread, valve plate 11 and spring 12 are limited in bellmouth valve seat, spring one end is placed on the boss of valve plate, and other end seat is on the step of bellmouth valve seat, and the other end of bellmouth valve seat is threaded connection on base tube.
(1) box cupling: for the connection between screen casing; (2) fluid control apparatus: the passage entering pit shaft as formation fluid, can according to the automatic regulates liquid flow of magnitude of pressure differential; (3) pressure ring is protected on: covering protection fluid control apparatus; (4) pressure ring is connected on: be fixed on base tube by the upper end of outer jointing jacket, filtration beds, internal protective cover; (5) pressure ring is connected under: be fixed on base tube by the lower end of outer jointing jacket, filtration beds, internal protective cover; (6) outer jointing jacket: formation fluid carries out coarse filtration, and stop the erosion of formation fluid to filtration beds; (7) filtration beds: formation fluid carries out secondary filter, prevents reservoir sand from entering pit shaft; (8) internal protective cover: be the enough flow channel of support liquid between filtration beds and base tube; (9) base tube: as the carrier installing above each parts.(10) top pressure ring: provide fluid course for liquid enters fluid control apparatus, and valve plate and spring are limited in bellmouth valve seat; (11) valve plate: produce motion after being subject to flow stream pressure, and then fluid course is provided; (12) spring: according to the motion of valve plate by force regulating valve plate; (13) bellmouth valve seat: accept spring, and form the regulable ring-shaped fluid course of liquid together with valve plate.
Formation fluid is successively through outer jointing jacket, filtration beds, internal protective cover and fluid control apparatus enter substrate tube, thus finally flow into pit shaft, the fluid control apparatus that each root screen casing is installed is unique passage that formation fluid enters pit shaft, this fluid control apparatus can according to the automatic regulates liquid flow of magnitude of pressure differential, when pressure reduction is larger, valve plate in fluid control apparatus moves to spring direction, annular fluid course between valve plate and bellmouth valve seat is reduced, the flow resistance of fluid increases, to keep the stable of fluid flow, thus the flow of each horizontal segment is carried out concentrating effectively control, realize the balanced production fluid of each horizontal segment of horizontal well.
Horizontal well liquid current control sand control screen is mainly used in the sand control field of open-hole horizontal well, by the flow adopting this liquid current control sand control screen automatically can regulate every root screen casing while preventing reservoir sand from entering pit shaft, make the Liquid output of horizontal well different parts unanimous on the whole, thus realize balanced production profile, delay the object of bottom water coning, extend the production period of validity of horizontal well.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
