Description
Technical field
the present invention relates to the adjustable filter in a kind of discharge area and control method, belong to downhole instrument technical field of structures.
Background technology
oil field is when carrying out eccentric water injection water distribution operation, and because injection allocation amount in different layers position is different, hole condition is also different.In order to ensure to meet injection allocation requirement, except needing different water nozzle bores, also need the filter screen with different discharge area.When using at the scene, need special instrument to cut net to adjustable stopper, due to the restriction of field condition, cut net operation very inconvenient, cut the shortcoming that net operation has irrecoverability in addition.
Summary of the invention
the object of the invention is to, the filter providing a kind of discharge area adjustable and control method, repeatedly to regulate the discharge area of filter easily and fast, thus overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that
the filter that a kind of discharge area of the present invention is adjustable is comprise urceolus, be provided with connecting hole bottom urceolus, and the periphery of urceolus is provided with three water holes be uniformly distributed along the circumference; Be provided with filter cylinder in urceolus, be provided with joint pin bottom filter cylinder, joint pin is connected with the connecting hole bottom urceolus; The periphery of filter cylinder is provided with three filter openings be uniformly distributed along the circumference, and filter opening place is provided with filter screen.
in aforesaid filtering plant, described connecting hole is polygonal hole, and aforementioned joint pin is the polygon post be connected with connecting hole.
a kind of method utilizing above-mentioned filter to carry out the adjusted water yield of the present invention is, the method is on urceolus, arrange three water holes be uniformly distributed along the circumference, and filter cylinder arranges three filter openings be uniformly distributed along the circumference, is provided with filter screen in filter opening; Filter cylinder is inserted urceolus, rotates filter cylinder, the overlapping area of modified water hole and filter cylinder, thus change the water amount of filter, to meet the different water imbibition demand in down-hole.
in preceding method, described rotation filter cylinder carries out calibration rotation by polygonal hole with coordinating of polygon post.During rotation, polygon post is extracted out in polygonal hole, after having rotated, then polygon post is inserted polygonal hole, fixing water amount.
owing to have employed technique scheme, compared with prior art, urceolus of the present invention is provided with three water holes be uniformly distributed along the circumference, and filter cylinder is provided with three filter openings be uniformly distributed along the circumference, and is provided with filter screen in filter opening; Carried out the overlapping area of modified water hole and filter cylinder by the relative angle changed between urceolus and filter cylinder, thus change the water amount of filter, to meet the water imbibition demand of every layer, every mouthful of well.Apparatus structure of the present invention is simple, and easily make, method is convenient and practical.Solve prior art scene and cut net inconvenience, cut the shortcoming of net operation irrecoverability.

Detailed description of the invention
below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
the structural representation of the filter that a kind of discharge area of the present invention is adjustable is as shown in Fig. 1 ~ Fig. 6, and this device comprises urceolus 1, is provided with connecting hole 3 bottom urceolus 1, and the periphery of urceolus 1 is provided with three water holes 5 be uniformly distributed along the circumference; Be provided with filter cylinder 2 in urceolus 1, be provided with joint pin 4 bottom filter cylinder 2, joint pin 4 is connected with the connecting hole 3 bottom urceolus 1; The periphery of filter cylinder 2 is provided with three filter openings 6 be uniformly distributed along the circumference, and filter opening 6 place is provided with filter screen 7.Connecting hole 3 is polygonal hole, and aforementioned joint pin 4 is the polygon post be connected with connecting hole 3.What draw in Fig. 1 is hexagonal hole and hexagonal prism, and what this example adopted is square hole and tetragonal prism.
a kind of method of the adjusted water yield of above-mentioned filter that utilizes of the present invention is, as shown in Figure 1, the method is on urceolus, arrange three water holes be uniformly distributed along the circumference, and filter cylinder arranges three filter openings be uniformly distributed along the circumference, is provided with filter screen in filter opening; Filter cylinder is inserted urceolus, rotates filter cylinder, the overlapping area of modified water hole and filter cylinder, thus change the water amount of filter, to meet the different water imbibition demand in down-hole.Rotating filter cylinder, is carry out calibration rotation by polygonal hole with coordinating of polygon post.During rotation, polygon post is extracted out in polygonal hole, after having rotated, then polygon post is inserted polygonal hole, fixing water amount.
adjustment process of the present invention is as follows:
polygonal hole in this example and polygon post are square hole and square post, so the water amount only having adjustment four different.According to field experience, filter screen can not be less than 1/2 net (residue block water part area occupied than) in most cases, and not high to required precision.So the corresponding discharge area of four positions is respectively 1/2 net in the present invention, 5/8 net, 3/4 net and 7/8 net, as shown in figures 3 to 6.Filter screen often rotates 90 °, and discharge area changes once.
