Prediction of Sand Production and Optimization of Sand Control Methods
The overlying rocks of deep water gas wells are replaced by lighter density water, which weakens the formation compaction and reduces the strength of rocks, resulting in loose reservoirs and increased sand production risks (Al-Awad et al., 1999). At the same time, because the production of deep water wells is usually large, once the sand is produced, it will seriously affect the safety of the

If the size of the sieve is too large, then in the case of production pressure less than 1MPa, sand production accounted for 19% of liquid production, indicating serious sand. Judging from the accumulation curve of sand production and the distribution of sand grains, free sand and weakly cemented sand will begin to appear in the stratum, and the formation rock skeleton will be destroyed and

How Is Sand Formed?
Sand’s makeup varies from place to place depending on the rocks, which have been eroded to create it. However, sand’s most common ingredient is silica. Other potential contributors to grains of sand include olivine, basalt, garnet crystals, limestone and virtually any other type of rock or mineral. In fact, some sand can be made entirely from shells.

How sand is made
Sand is a loose, fragmented, naturally-occurring material consisting of very small particles of decomposed rocks, corals, or shells. Sand is used to provide bulk, strength, and other properties to construction materials like asphalt and concrete. It is also used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a molding material for
