摘要： An assembly may include a diverter extending inwardly from a casing string and extending along a length of the casing string. The assembly may also include a cavity defined by the diverter and the casing string. The cavity may be for receiving debris particles accumulated by a centrifuge positioned proximate to the diverter. The assembly may also include a valve extending between an inner surface of the casing string and an outer surface of the casing string, the valve may be in fluid communication with the cavity.

摘要： An unloader valve assembly includes a cylindrical housing defining an annular space, an inner wall thereof including a port that enables fluid communication between the annular space and a location outside the inner wall of the housing. A mandrel having a tubular configuration is positioned inside the housing, the mandrel defining a central bore for receiving fluid and includes a mandrel port enabling fluid communication between the central bore and the annular space. A piston encircling the mandrel is movable along an axis defined by the central bore. A spring is situated between the inner wall of the housing and the mandrel and movable between an extended configuration urging the piston downwardly and a compressed configuration being urged upwardly by the piston.

摘要： Determining a type of annular material in a wellbore comprises measuring an acoustic noise of one or more reference materials and thereby generating a corresponding one or more acoustic profiles, monitoring the annular material with an acoustic sensor positioned in the wellbore and thereby obtaining an acoustic response of the annular material, comparing the acoustic response with the one or more acoustic profiles using a processor communicably coupled to the acoustic sensor, and characterizing the annular material based on the comparison of the acoustic response and the one or more acoustic profiles.

摘要： Methods and systems are presented in this disclosure for performing multi-frequency communications during wellbore operations. Communication of data related to a state of a wellbore (e.g., characteristics and/or locations of one or more fluids flowing along a casing in the wellbore during a cementing operation) can be performed simultaneously or sequentially involving a plurality of nodes located along the casing in the wellbore, wherein each of the nodes is configured to use a different frequency for communication. In this way, a higher information throughput and more reliable communication can be achieved during wellbore operations.

摘要： Drilling fluid compositions include a base fluid, at least one additive chosen from an emulsifier, weighting material, fluid-loss additive, viscosifier, or alkali compound, and from 0.1 wt. % to 1 wt. %, based on total weight of the drilling fluid composition, of an ethoxylated alcohol compound having the formula R—(OCH2CH2)7—OH, in which R is a saturated or unsaturated, linear or branched hydrocarbyl group having from 8 to 20 carbon atoms. The base fluid may be an aqueous base fluid. Methods for drilling a subterranean well include operating a drill in a wellbore in the presence of a drilling fluid composition including the base fluid, the additive, and the ethoxylated alcohol compound.
