IMPROVING THE EFFICIENCY OF SLUDGE CLEANING AT THE FIELDS OF THE EAST-URENGOY LICENSED AREA

Annotation. Optimization of expenses during the drilling of oil and gas wells is a key factor in improving the process of their construction. Particular attention is paid to the costs of maintenance and quality support of drilling fluids. This article discusses the technology of cleaning drilling fluid and dewatering sludge at a mobile sludge dewatering unit. The drilled rock can deteriorate the properties of the drilling fluid, so it must be removed. Cleaning is implemented either by a natural (gravitational) method, when particles settle in troughs and tanks, or by forced method – due to vibration and centrifugal forces. The mechanical devices used operate on different physical principles and allow reducing the interaction time of the abrasive with the drilling fluid, preserving its quality and characteristics. The technological effect of using the mobile sludge dewatering unit when drilling horizontal wells of gas wells at the East-Urengoy licensed area, where hydrocarbon-based muds are used, is that the hydrocarbon-based mud extracted from oil sludge can be reused after minor adjustment of its properties to the established parameters, and the oil sludge is dewatered in accordance with strict environmental regulations. In addition, reducing the moisture content of the sludge also leads to a reduction in the volume of drilling fluid disposal.

Keywords: mobile sludge dewatering unit, drilling fluids, hydrocarbon-based muds, drilling, horizontal wells, sludge.
