Abstract
The utility model provides an intelligent sieve tube, comprising a base tube, a baffle ring and a sand blocking element, wherein a kerf is fixed on the base tube, the baffle ring is fixed on the base tube, the sand blocking element is sleeved out of the base tube, the baffle ring and the sand blocking element os symmetrically installed on the base tube, the baffle ring is fixed at two ends, the space sleeve is fixed between the sand blocking elements, the kerf is fixed at the lower of the upper sand blocking element, and the kerf is fixed at the upper of the lower sand blocking element. A permeable downhole filter is fixed between the base tube and the space sleeve. The kerf is fixed on the upper and the lower of the sand blocking element, the positions of the kerf and the sand blocking element are staggered, the fluid enters the base tube afer flowing upwards and downwards without directly entering the base tube after flowing through the and blocking element, which will not break the kerf. The intelligent sieve tube has the advantages of long service life, long production period of the oil well and obvious economic benefit.
Description
Technical field
The utility model be oil field pit shaft sand control use instrument, be a kind of intelligent screen casing.
Background technology
Existing sand screen generally is made up of parent tube, composite filter, protection outer tube; the protection outer tube sleeve is contained in outside the parent tube; between parent tube, the protection outer tube is composite filter, and parent tube is provided with flowing hole, and composite filter is over against flowing hole; liquid stream directly rushes at flowing hole after composite filter inwardly flows; cause flowing hole to enlarge gradually, damage parent tube at last, the sand control period of validity is shortened; reduce the oil well production cycle, produce heavy economic losses.
Summary of the invention
The purpose of this utility model provides a kind of intelligent screen casing, improves the application life of parent tube, prolongs the oil well production cycle.
The purpose of this utility model has been achieved in that parent tube, baffle ring, sand block element, slot is arranged on the parent tube, baffle ring is fixed on the parent tube, the sand block element housing is contained in outside the parent tube, baffle ring, sand block element symmetry are installed on the parent tube, and baffle ring is in two ends, and spacer is between the sand block element, slot is in the below of sand block element, and slot is in the top of sand block element down.
Between spacer and the parent tube sand screen is installed.
The beneficial effects of the utility model are: slot is in sand block element upper and lower, slot and sand block position of components stagger, liquid stream does not directly enter in the parent tube after the sand block element enters, liquid stream just enters parent tube in after needing upwards to flow downwards, can not sting the damage slot, the parent tube long service life, the oil well production cycle is long, has remarkable economic efficiency.
