Abstract

La invencion esta referida a componentes de una sarta de perforacion que comprende una rosca que se extiende alrededor de un cuerpo. El extremo delantero de la rosca puede tener una configuracion que resiste atascos y roscado incorrecto. En particular, el extremo delantero de la rosca puede incluir una superficie plana paralela al cuerpo. El extremo delantero de la rosca puede proporcionar una transicion abrupta a toda la profundidad de la rosca que ayuda a reducir o eliminar el roscado incorrecto. El extremo delantero de la rosca puede estar orientado en un angulo respecto del eje del componente de sarta de perforacion. Cuando las roscas macho y hembra coincidentes tienen estructura similar, las roscas coincidentes se deslizan juntas a lo largo de una interfaz en la cara de inicio de rosca y se llevan a una condicion totalmente acoplado por roscas. Los inicios de rosca pueden tener una coincidencia de circunferencia total sin posiciones de atascoThe invention relates to components of a drillstring comprising a thread extending around a body. The forward end of the thread may be of a configuration that resists jamming and improper threading. In particular, the forward end of the thread may include a flat surface parallel to the body. The leading end of the thread can provide an abrupt transition to the full depth of the thread that helps reduce or eliminate misthreading. The forward end of the thread may be oriented at an angle to the axis of the drillstring component. When the mating male and female threads have similar structure, the mating threads slide together along an interface on the thread start face and are brought into a fully thread-engaged condition. Thread starts can have full circumference match with no jam positions
