Abstract
The invention relates to a test system for sand control screen pipes. The test system for the sand control screen pipes comprises a slurry tank and a simulated well bore connected with the slurry tank. The simulated well bore is a closed high-pressure well bore, an outlet is formed in one end of the well bore, a pump and a pressure gauge are arranged on a slurry container, and another pressure gauge is arranged on the simulated well bore. The test system for the sand control screen pipes has the advantages of simple connection structure and high practicality.
Description
Technical field
The present invention relates to a kind of oil well sand control screen tube test macro.
Background technology
Screen casing strength character can reflect the ability of the anti-destruction of screen casing, once screen casing is destroyed, will cause oil well normally to produce, and even causes oil well to scrap, and brings serious economic loss.The destruction of screen casing is mainly caused by various load, the load that screen casing may be subject in lower people's oil well and manufacturing process mainly contains 6, (1) tensile load (2) bottom hole temperature (BHT) stress can produce compressive load (3) and is lowered to while being hampered, and rotation screen casing produces torsional load.(4) moment of flexure at angle buildup interval, hole angle or azimuth well section jumpy, be subject to the effect (5) of moment of flexure along with the exploitation of oil reservoir, pore pressure can reduce gradually, and stratum can be by compacting sinking gradually, well produces necking down, and screen casing is produced to extrusion load; (6), in oil well completion process, after the inner or outside obstruction of screen casing, the head of liquid that highdensity oil well working solution produces applies interior swollen load to screen casing inside.At present, offshore company pays much attention to the evaluation of screen casing collapsoing strength and anti-interior swollen intensity, and has drafted examination criteria, but not yet has into the checking system of standard at present.
Summary of the invention
The present invention proposes the good sand control screen test macro of a kind of test effect.
A kind of sand control screen test macro of the present invention, comprise slurry tank and the simulation wellbore hole being attached thereto, described simulation wellbore hole is the high pressure pit shaft of sealing, and one end of pit shaft is provided with outlet, slurry container is provided with the pump housing and pressure meter, is also provided with pressure meter on described simulation wellbore hole.
A kind of sand control screen test macro of the present invention, the simple and practical property of syndeton is strong.
Accompanying drawing explanation
Fig. 1 is syndeton schematic diagram of the present invention.
1-slurry tank in figure; 2-simulation wellbore hole; 3-outlet; The 4-pump housing; 5-pressure meter.
The specific embodiment
A kind of sand control screen test macro of the present invention, comprise slurry tank 1 and the simulation wellbore hole 2 being attached thereto, the high pressure pit shaft that described simulation wellbore hole 2 is sealing, one end of pit shaft is provided with outlet 3, slurry container is provided with the pump housing 4 and pressure meter 5, on described simulation wellbore hole 2, is also provided with pressure meter 5.
During use, by one end shutoff of screen casing, be then placed in simulation wellbore hole 2, the other end is connected in outlet 3, then opens the pump housing 4, in simulation wellbore hole 2, pumps into the polymer slurry containing sealing agent, annular space rotation after slurry enters in simulation wellbore hole 2, by screen casing, now, continuous pump people slurry constantly, increase pressure, until meet the requirements of anti-collapsing pressure, or slurry stops while there is leakage, and now the force value of pressure meter 5 correspondences in simulation wellbore hole 2 is the collapse resistance of screen casing.
Claims (1)
1. a sand control screen test macro, it is characterized in that: the simulation wellbore hole (2) that comprises slurry tank (1) and be attached thereto, described simulation wellbore hole (2) is the high pressure pit shaft of sealing, one end of pit shaft is provided with outlet (3), slurry container is provided with the pump housing (4) and pressure meter (5), is also provided with pressure meter (5) on described simulation wellbore hole (2).
