Magnesium lignosulfonate is used as oil well cement admixture
Magnesium lignosulfonate:
Cement is used in the cementing operation of oil Wells. The cementing quality is related to many factors, such as the loss of water in the cement slurry, the flow pattern of the cement slurry and the setting time of the cement slurry, so various cement admixtures are required. Cement admixtures include promoting early strength agent, retarding agent, water loss agent, anti-gas channeling agent, dispersant, expansion agent, cement stone strength main anti-decay additives, free water control and solid suspension regulator, clay control agent, etc.
Lignin oil well cement admixtures are mainly used as retarding agent and dispersant agent. Now the most commonly used oil well cement retarder is lignosulfonate, lignosulfonate class of medium and low temperature retarder, mostly used in shallow Wells. Lignosulfonate supplemented with sodium humate or tartaric acid can also be used as high temperature retarder, is characterized by less dosage, good effect, economy, and a variety of cement has good compatibility.
Cementing cement dispersion retarding agent magnesium lignesulfonic acid is composed of lignesulfonic acid and other raw materials. It has the advantages of good rheological property of cement slurry, easy adjustment of thickening time, convenient field use and so on. It is a kind of high quality and efficient oil well cement admixture.
Magnesium lignosulfonate can also be used as a dispersant in kill fluid.
