Desc:In order to protect the modern environment, it is necessary to prevent well collapse, well loss and protect the oil and gas reservoir. For the formation with developed bedding and fracture, in order to prevent well collapse and leakage and reduce the damage to oil and gas reservoir, the drilling fluid is required to have strong sealing property, effectively seal the bedding and fracture of the formation, prevent the drilling fluid and its filtrate from entering the formation, so as to improve the pressure bearing capacity of the formation, stabilize the well wall, prevent well leakage and protect the oil and gas reservoir. Chongqing Chuandong Chemical Group will talk about the detailed values of potassium formate and sodium formate in weighting agent of drilling and completion fluid.
