5 Claims

1. A downhole device for hydrocarbon producing wells without conventional tubing (tubingless completion), wherein the device comprises:

(a) a first section (200) comprising a filtering element with annular ovoid sintering (202) and a protective housing (201);

(b) a second section (300), connected to an upper end of the first section (200) and comprising a primary flow conditioner, in which the hydrocarbon flow (704) enters to a progressively decreasing cross section (303) until reaching a circular flow area (304) which extends as a cylindrical portion to transport the flow from bottomhole to surface;

(c) a third section (400) connected to an upper end of the second section (300) by an external sleeve (401) comprising a homogenization and stabilization chamber (407) which has external sleeves (401, 403 and 404), wherein the chamber is connected with a support (405) that seals (406) against the external sleeve (401), wherein the homogenization and stabilization chamber (407) has a flow area and length that is connected at upper end (408) with a secondary flow conditioner, and outside supports of an anchoring and sealing system and the external sleeves (401, 403 and 404) of the homogenization and stabilization chamber (407);

(d) a fourth section (500) comprising the anchoring and sealing system consisting of a tubular cylindrical portion (502) which has an outside provided with a set of anchors (501) fixed to a part of an interior well pipe, wherein the anchors are spaced from each other in a radial direction and provided with a clamp or parallel set of stepped rows to partially penetrate the interior of the well pipe; wherein the anchoring and sealing system is also provided with a series of flexible coaxial annular joints (507) spaced longitudinally to each other with spacer rings (504) and anchors (501) placed on an external face, internally supported by a cylindrical portion (502), and externally supported by protective sleeves (503, 505 and 506); and

(e) a fifth section (600) comprising the secondary flow conditioner, which has a central passage opening (607) with a cross section that decreases at a constant acute angle with respect to an axis of symmetry until reaching a circular flow area which extends as a cylindrical portion (606) which has diagonally oriented openings called suction veins (603), which point towards the bottomhole to create a passage to a higher velocity zone, and, wherein the secondary flow conditioner is connected to a support (601) with the homogenization and stabilization chamber (407) by means of a connection (408) in the upper end, that allows the flow to exit in accelerated form through the central passage opening (607).
