Sand-sized particles larger than 74µm are defined as sand content of a drilling fluid. The volume of sand, including that of void spaces between grains, is usually measured and expressed as volume percent. Sieve analysis is the preferred method for sand content determination because of the reliability of the test and simplicity of equipment.
Excessive sand may result in the deposition of a thick filter cake on the wall of the hole, or may settle in the hole about the tool when circulation is stopped, thus, interfering with successful operation of drilling tools or setting of casings. High sand content also may cause excessive abrasion of pump parts and pipe connections.
The Sand Content Kit consists of special developed sieve with mesh-size 0,08 mm (200-mesh), a proper plastic funnel and a special modeled measuring tube. A mark at the measuring tube indicates the amount of the filled in drilling fluid. The percentage of sand may read off directly from the measuring tube graduated from 0 to 20%.
