摘要： In order to achieve the above-described objectives, the present invention provides an adapter tool for coupling a bend stiffener with diverless bell mouth (DLBM) interface in a bell mouth with BSN900E-type interface. The adapter tool is capable of maintaining interchangeability and flexibility between designs or design phases, even if different bell mouth models are used. A tool characterized in that it comprises an adapter split ring (10) that, in the upper part, has a geometry compatible with the dovetail profile of the BSN900E model helmet and, in the lower part, has a geometry compatible with the seating profile of the DLBM helmet (40). The present invention leads to two assembly methods, which guarantee the operational safety of the adapter assembly, namely: a method where it is only done by screws located in the split ring; and another, where the assembly includes, in addition to the split ring, an assembly with the support ring and rods.

摘要： A system, apparatus, and method for determining intact versus fractured rock zones based on performance monitoring of an electric drilling machine when drilling a blasthole. The determination can be based on a calculation of compensated blastability index (“CBI”) values using transformed performance monitoring data collected in real-time as the drilling machine drills the blasthole.

摘要： A main winch system of a rotary drilling rig includes a main action loop, a pilot control loop, and a feedback control loop. The main action loop includes an engine, a hydraulic pump, a main control valve, a balance valve, a main winch motor, and an oil tank. The pilot control loop includes a pilot handle, a solenoid valve I, a pressure relay, and the main control valve in the main action loop. The feedback control loop includes a solenoid valve II and the hydraulic pump and the main control valve in the main action loop. In response to a lifting action of the pilot handle for the main winch, under the control of a button, the solenoid valve II is energized continuously, and the solenoid valve I is energized and de-energized according to a given rule.

摘要： Dimensions of a tool moving in/out of a well may be measured during well operations. The measured dimensions of the tool may be used to analyze the well operations. Analysis of well operations may include identification of types of well operations being performed at the well, monitoring of the well operations, benchmarking of the well operations, identification of tools being used in the well operations, and/or other analysis of the well operations.

摘要： A riser termination connects a steel riser duct to an I-tube or J-tube connecting interface of a floating unit, and includes an upper hang off portion, lower coupling adapter, steel termination conduit having an upper conduit end connected to the upper hang off portion and a lower conduit end connected to the steel riser duct. The termination conduit extends axially slidable through the coupling adapter. A circular cylindrical bearing seat is formed inside the coupling adapter and defines a bearing seat diameter, a bearing body having a bearing body diameter and protruding outward from the termination conduit inside the bearing seat. The bearing body diameter is smaller than the bearing seat diameter. A gap between the bearing body and the bearing seat allows relative sliding and rotation. The termination conduit includes a variable cross-section conduit portion having a diameter and wall thickness decreasing from the bearing body.

摘要： An anti-collision method includes storing information on a current position of at least one vehicle within a target work volume, scanning the target work volume by a radiofrequency radiation signal to detect the presence of at least one human operator within the target work volume, determining the current position of the at least one human operator within the target work volume, comparing the current position of the at least one human operator with the current position of the at least one vehicle, and, if the current position of the at least one human operator at least partially overlaps the current position of the at least one vehicle, activating at least one safety device.
