Wire wrapped screen gravel pack sand control technology Features

High-strength compacted sand gravel backfill sand migration obstruct the formation matrix, wire wrapped screen and great strength, large flow area through the sieve slit activities little resistance.
Long period, because stainless steel wire wrapped screen corrosion, stable chemical properties of quartz sand filtration system has no moving parts, sand isolated outside the system, and therefore has a very long duration.
Usually sand approach inevitably bring oil production capacity is lost, the normal inner tube gravel packing capacity lost Jianyue 30%, but the adoption of remedial measures can be reduced to 10%. Normal inner tube gravel packing capacity lost Jianyue 30%, but the adoption of remedial measures can be reduced to 10%, but the adoption of remedial measures can be reduced to 10%.
After years of spreading, the technology is mature, many technical options available, so the formation, well adaptability. Regardless of the length of the well section, formation fluid characteristics, regardless of vertical wells, deviated conventional wells, thermal recovery wells, single or multi-layer, the success rate is very high. But powder fine sandstone with caution. Systems engineering high-impregnated sand formed near the wellbore fluid reduces the pressure gradient, and then reduce or avoid the destruction of the rock, that is to reduce the extent and trend of sand. At the same time the project of formation sand sand bridge plug has a good effect, formation fluid with the formation sand barrier project in the sand outside, and wire wrapped screen sand have blocked the project, constitute a good secondary barrier block sand, sand end intention.
Use something under the selected slit scale wire wrapped screen sand into the well being of the reservoir, the choice of high-pressure, large displacement of the belt project to produce oil and gas well casing layer and an outer screen and vague casing annulus in formation must constitute a solid block in the sand barrier high penetration depth, large radius must radius, and then adjust the parameters of the construction, so projects in the oil sand accumulation within the casing annulus, the end of the casing annulus filling.
