摘要： An apparatus includes an inflow control device that is disposed in a well and is adapted to receive a flow. The inflow control device includes a chamber, an outlet and at least one inlet. The chamber has a first end, a second end, and a cross-section of the chamber decreases along a length of the chamber. The outlet is disposed at the second end of chamber. The inlet has a cross-sectional dimension and is adapted to, in response to the received flow, inject a flow into the chamber near the first end of the chamber such that a fluid flow is produced inside the chamber that rotates and translates in a direction along the length of the chamber toward the outlet.

摘要： In general, the invention relates to a drill bit. The drill bit includes a first tubular member including a pin end and a pin thread structure extending helically along an outer surface of the pin end in spaced thread turns, the pin thread structure including: a first pin flank and a second pin flank; a pin crest extending between a top edge of the first pin flank and a top edge of the second pin flank; and a pin root extending between a bottom edge of the first flank and a bottom edge of a flank of an adjacent thread turn. The drill bit also includes a second tubular member including a box end and a box thread structure extending helically along an inner surface of the box end in spaced thread turns, the box thread structure including a first box flank and a second box flank; a box crest extending between a top edge of the first box flank and a top edge of the second box flank; and a box root extending between a bottom edge of the first box flank and a bottom edge of a box flank of an adjacent thread turn, where the pin end and the box end are threadedly connected and a width of the box root is less than a width of the pin root.
