摘要: Certain conditions require powering down an engine driving a pump. During the down sequence the pump may continue pumping servicing fluid which may not be desirable. Activating one or more control valves may throttle or prevent the servicing fluid from being pumped from the pump during the power down sequence. Activation of an input control valve may introduce pressurized fluid into a cylinder of the pump extending a rod to force or maintain a suction valve in an open position. While the suction valve is in the open position, the stroke of the plunger may not create enough pressure to pump the servicing fluid causing the servicing fluid to flow between a fluid header and a chamber of the pump. Activation of an output control valve may divert servicing fluid pumped from the pump to a reservoir instead of to the desired location.

摘要: A valve guide for a fracturing pump valve assembly, the valve guide include a ring member having one or more blades. The one or more blades project inward from an annular ring of the ring member, a first side of the one or more blades defining a central space of the ring member, the central space configured to contain a cross-sectional portion of a valve post of the valve assembly therein and the first side extending parallel to a long axis length of the valve post. Valve assemblies and hydraulic fracturing systems including the valve guide are also disclosed.

摘要: A gate valve having a valve body defining a flow passage therethrough. The gate valve has a movable gate with an upper and a lower edge for opening and closing the flow passage and a lifting stem extending from the upper edge of the gate configured to move the movable gate between open and closed positions. At balancing stem is configured to offset at least a portion of the force applied to the lifting stem by a fluid flowing through the gate valve when the movable gate is moved between open and closed positions.

摘要: Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

摘要: Electrically ignitable and electrically controllable explosive material (EIECEM) may be disposed within a shaped charge for deployment downhole. An explosion of the EIECEM is controlled by limiting the duration of excitation at the EIECEM, for example, the duration that an electrical source provides an electrical charge, electrical current or electrical signal. The shaped charge may be insulated from an electrical source to prevent explosion of the EIECEM and coupled to the electrical source to create ignite or explode the EIECEM. A plurality of shaped charges may be disposed downhole and may be ignited or exploded in any suitable order. The EIECEM may be ignited multiple times such that multiple explosions are created. The explosion of the EIECEM creates or extends a perforation or fracture in a formation. The shaped charges may be excited in a predetermined sequence and for a predetermined duration of time.

摘要: In accordance with embodiments of the present disclosure, systems and methods for using containers of bulk material along with a bucket conveyor system, instead of a pneumatic transfer process, to move the bulk material from a transportation unit to a storage/delivery system are provided. A transportation unit may deliver one or more containers full of bulk material toward a fill hopper of the bucket conveyor system. The containers may be positioned proximate the fill hopper to release the bulk material directly into the fill hopper. The bucket conveyor may deliver the bulk material from the fill hopper into the storage/delivery system. Since the containers are maneuverable into a position to output bulk material directly into the fill hopper and without pneumatic transfer, the bucket conveyor system may enable a cleaner and more efficient bulk material transfer at the site.

摘要: A method includes conveying a casing cutting tool into the wellbore lined with at least one casing string and cement, and stroking the casing cutting tool over a predetermined axial length of the wellbore while ejecting fluid from one or more nozzles in the casing cutting tool and thereby forming a plurality of longitudinal cuts through the casing string and cement. The casing cutting tool is then rotated about its longitudinal axis at two or more axially offset locations along the predetermined axial length while ejecting fluid from nozzles and thereby forming a plurality of axially offset transverse cuts in the casing string and the cement. The longitudinal cuts and axially offset transverse cuts form wedges in the wellbore, and the wedges are dislodged from the wellbore to expose formation rock along the predetermined axial length.
