摘要： A method can include directing fluid flow longitudinally through a well tool connected in a tubular string downstream of a longitudinally compressed circulating valve assembly, thereby causing the well tool to operate, and longitudinally elongating the circulating valve assembly while the fluid flow is ceased, and then increasing the fluid flow, thereby causing the fluid flow after the elongating to pass outwardly through a housing of the circulating valve assembly to an external annulus. Another method can include directing a fluid flow through a well tool connected in a tubular string downstream of a circulating valve assembly, thereby causing the well tool to operate, and decreasing then increasing a flow rate of the fluid flow, thereby causing the fluid flow to pass outwardly through a housing assembly of the circulating valve assembly to an external annulus. Circulating valve assemblies are also disclosed.

摘要： A fluid pulse generator can include a fluid motor including a rotor that rotates in response to fluid flow, a variable flow restrictor positioned upstream of the fluid motor and including a restrictor member rotatable relative to a ported member and longitudinally displaceable relative to the rotor. Another fluid pulse generator can include a flex joint or a constant velocity joint connected between the restrictor member and the rotor. In another fluid pulse generator, the variable flow restrictor can include a valve and a fluidic restrictor element, the valve being operable in response to rotation of the rotor, the fluidic restrictor element being configured to generate fluid pulses in response to the fluid flow through a flow path, and the valve being configured to control the fluid flow through another flow path connected in parallel with the first flow path.

摘要： A downhole well tool assembly can include a perforator and a selectively openable and closable perforation plug discharge port. A method of perforating and treating multiple formation zones of a well in a single trip of a downhole well tool assembly into the well can include positioning the downhole well tool assembly at a zone, closing a perforation plug discharge port of the downhole well tool assembly, perforating the zone, treating the zone, opening the perforation plug discharge port, deploying perforation plugs into the well via the perforation plug discharge port, plugging perforations in the zone with the perforation plugs, positioning the downhole well tool assembly at a subsequent zone, closing the perforation plug discharge port, perforating the subsequent zone, and treating the subsequent zone.

摘要： A fluid pulse generator can include a fluid motor and a bypass flow path in fluid communication with an inlet and an outlet, and a flow control device configured to permit flow through the bypass flow path in response to a predetermined pressure differential applied across the flow control device. A method of generating fluid pulses can include flowing a fluid through a fluid pulse generator, thereby generating fluid pulses, and then applying a predetermined pressure differential from an inlet to an outlet of the fluid pulse generator, thereby permitting flow of the fluid through the fluid pulse generator without generating the fluid pulses. A fluid pulse generation system can include a fluid pulse generator with a fluid motor, a variable flow restrictor, and a bypass flow path. A predetermined pressure differential applied across the fluid motor permits the flow of the fluid through the bypass flow path.

摘要： A system can include a disconnect tool connected as part of a tubular string, the disconnect tool including an outer housing, and an inner mandrel in the outer housing, in which an abrasive slurry is directed to flow through the tubular string and from the inner mandrel to an annulus between the inner mandrel and the outer housing, and the abrasive slurry erodes through the outer housing. A method can include installing a tubular string in a well, then deploying a disconnect assembly into the tubular string, and flowing an abrasive slurry through the disconnect assembly, thereby parting the tubular string. A disconnect tool can include a rotational flow structure configured to induce rotational flow, and an inner diameter decrease downstream of the rotational flow structure.

摘要： A method of constructing a plugging device can include incorporating multiple filaments into the plugging device, and coating each individual filament with a swellable material. A plugging device for use in a subterranean well can include a body comprising multiple filaments, and a swellable material on each of the individual filaments. A system can include a plugging device conveyed by fluid flow into engagement with an opening, whereby the plugging device blocks flow through the opening. The plugging device can include multiple filaments, each of the multiple filaments being coated with a swellable material. The swellable material may seal against a surface of the opening.

摘要： A method of releasing plugging devices into a wellbore can include conveying a dispensing tool to a desired downhole location in the wellbore, the dispensing tool including a container, and then releasing the plugging devices from the container into the wellbore at the downhole location. A plugging device dispensing system for use with a subterranean well can include a dispensing tool having a container configured for containing multiple plugging devices, and an actuator operable to release the plugging devices from the container at a downhole location in the well.

摘要： A well completion method can comprise, in a single trip into a wellbore, the following steps being performed for each of multiple zones penetrated by the wellbore: abrasively perforating the zone with a tubing deployed perforating assembly, fracturing the perforated zone with flow from surface via a well annulus, and then plugging the fractured zone with a removable plug substance, the perforating assembly displacing in the wellbore while the fractured zone is being plugged. Another well completion method can comprise, in a single trip into a wellbore, the following steps being performed for each of multiple zones penetrated by the wellbore: perforating the zone using an abrasive perforator, then displacing the perforator in the wellbore away from the earth's surface, then fracturing the zone, and plugging the fractured zone with a flowable plug substance.
