| description | FIELD: chemistry. ^ SUBSTANCE: invention relates to drilling fluids and can be used in oil-extraction industry. The water-based drilling fluid contains the following in wt %: clay 0.1-5.0; carboxymethyl cellulose 0.3-0.4; excess sludge from biological treatment plants 5.0-10.0; water - the rest. ^ EFFECT: lower yield point with retention of high viscosity, low water loss and high salt resistance. ^ 2 tbl, 3 ex
Изобретение относится к буровым промывочным растворам и может быть использовано в нефтедобывающей промышленности. Технический результат - уменьшение величины предельного напряжения сдвига, при сохранении высокого значения вязкости, низкого значения водоотдачи и высокого значения солестойкости. Буровая промывочная жидкость на водной основе содержит, вес.%: глина 0,1-5,0; карбоксиметилцеллюлоза 0,3-0,4; избыточный ил биологических очистных сооружений 5,0-10,0; вода - остальное. 2 табл. |
