Ceramsite performance characteristics

Ceramsite performance characteristics
Oil and gas well sand production is one of the important problems facing the loose sandstone reservoir. The petroleum proppant of sand production is mainly manifested in the following four aspects:Oil and gas well production or shut down
Oil and gas well sand production, easy to cause sand buried reservoir, sand plug tubing and manifold and storage tanks in the sand, which was forced to shut down operations. Rinse the sand buried reservoir, sand plug removal of tubing, both time-consuming and expensive, also can't completely solve problem. To resume production soon and need to work, live, shorter production cycle and make the oil and gas production, homework cost huge increase, serious economic loss.
The ground and underground equipment and pipeline abrasion
Hydrocarbon flow carried in the formation of sand main high density ceramic is sio2, the hardness is very high, is a destructive strong abrasive, can make the pump seat wear and no seal, valve ball pitting, rod and pump cylinder strain, ground valve failure, serious erosion, oil transfer pump impeller thus forced to shut-in homework, replace or repair the equipment, cause the loss of production, the cost is rising.
Casing damage to oil and gas Wells scrap
Serious sand production for a long time in outside casing a huge hole, inner and outer force imbalance lead to sudden formation collapse, cause casing deformation, light weight, casing was wrong fault collapsing, lead to oil and gas Wells of scrapped.
Destroy the formation of the original structure or cause the formation permeability near wellbore area of serious decline
Oil and gas well after the sand, sand migration, formation sand near wellbore area of sedimentation is more, far wellbore area becomes loose structure. Caused a significant reduction in the formation permeability near wellbore area, oil and gas well production decline.
Solve the problem of oil and gas Wells sand production, must be based on the early prevention and control, to reduce the damage to the reservoir cementing
