Oil casing slotted sand control screen tube
Slotted screen tube is a type of screen tube that cuts fine slits on the casing or oil pipe body, blocking the formation sand outside the screen tube to achieve sand control. Its structure is simple and cost-effective, and it can be used for completion and sand control of curved wellbore such as horizontal wells. The basic structure of slotted screen tube is similar to that of sintered mesh screen tube, but the protective sleeve adopts a three-dimensional gap that is stretched, stamped, and spiral arranged. The oil well production fluid flows into the screen tube through the three-dimensional gap, which can effectively avoid direct erosion and damage to the filter layer by the fluid, extend the service life of slotted screen tube, and is suitable for high liquid content sand production wells.

Slotted screen tube is a type of screen tube that cuts fine slits on the casing or oil pipe body, blocking the formation sand outside the screen tube to achieve sand control. Its structure is simple and low cost, and it can be used for completion and sand control of curved wellbore such as horizontal wells. The basic structure of slotted screen tube is similar to that of sintered mesh screen tube, but the protective sleeve adopts a three-dimensional gap that is stretched, stamped, and spiral arranged. The oil well production fluid flows into the screen tube through the three-dimensional gap, which can effectively avoid direct erosion and damage to the filter layer by the fluid, extend the service life of slotted screen tube, and is suitable for high liquid content sand production wells. For some boundary wells with low reserves and sand production, the overhaul plan of using conventional sand control methods and repair equipment to complete the well again is not cost-effective economically. However, some remedial measures, including using steel wire ropes to salvage sand or flushing sand with continuous tubing, are only temporary measures and cannot effectively solve sand production in oil wells and maximize the recovery of oil production capacity. This type of sieve tube is generally wrapped with three layers of sieve cloth, and the holes of each layer of sieve gradually become smaller from the outside to the inside. The outermost layer forms a large sand bridge, and the middle layer forms a medium sand bridge; Smaller sand particles form sand bridges in the innermost layer; No matter how small the formation sand flows into the wellbore.
