Abstract:
A laser measuring system for continuous measurement of a plurality of connected tubulars being inserted into or removed from a wellbore. The laser measuring system can have a laser housing with one or more laser surface velocimeters. The laser housing with a laser arm can be connected to a support member and can communicate via a network to a computer processor and data storage for measuring pipe joint length in real time. A pressurized gas port can pressurize the laser housing above ambient pressure to keep a laser beam clear of particulate and well fluids or ambient pressure can be used with a continuous airflow device. The laser beam is used to detect and calculate length and quantity of tubulars moving past the laser beam transmitting the information to the computer processor in real time.

Claim (Index 1):
A laser measuring system for automatic continuous measurement of multiple rotating tubulars being inserted into or removed from a wellbore, the laser measuring system comprising:\n a. a support member having a center hole, the center hole aligned with the wellbore, the center hole configured to receive multiple rotating tubulars connected in series, the support member having a plurality of laser beam openings, each laser beam opening penetrating to the center hole, the support member connecting between an upper mounting member and a lower mounting member; b. a plurality of rigid debris deflection devices, each rigid debris deflection device covering one of the laser beam openings in the support member; c. an upper pipe wiper with a upper wiper opening connected to the upper mounting member and a lower pipe wiper with a lower wiper opening connected to the lower mounting member for cleaning each rotating tubular between the upper mounting member and the lower mounting member; d. a plurality of laser arms connected to the support member at an angle to a longitudinal axis of each rotating tubular; e. a plurality of laser housings connected to and aligned with one of the plurality of laser arms; f. a plurality of laser surface velocimeters connected to a power supply, each laser surface velocimeter positioned in one of the laser housings and oriented to project a laser beam onto each rotating tubular being pulled or pushed through the central hole, one of the plurality of laser surface velocimeters is configured to:\n (i) measure an axial surface speed for each rotating tubular being run into and out of the wellbore and form a velocity measurement; \n (ii) count a total quantity of rotating tubulars being run into and out of the wellbore per run; and \n another of the plurality of laser surface velocimeters is configured to:\n (i) measure a rotating surface speed for each rotating tubular being run into and out of the wellbore forming a rotation measurement; and \n (ii) calculate a total length of all the connected rotating tubulars being run into or out of the wellbore; \n \n g. a computer processor in electronic communication with each laser surface velocimeter; h. a data storage in communication with the computer processor, the data storage providing instructions for the computer processor to:\n (i) calibrate each laser surface velocimeter; \n (ii) receive and store measurements from each laser surface velocimeter; \n (iii) calculate lengths of each rotating tubular as each rotating tubular is run into an out of the wellbore; \n (iv) calculate total quantities of rotating tubulars being run into and out of the wellbore; and \n (v) calculate a total length of all rotating tubular being run into or out of the wellbore; \n (vi) use a non-linear function to remove the rotation measurements from the velocity measurements for each rotating tubular enabling isolation of rotation or velocity measurements by rotating tubular to provide a total length of each tubular, total depth of all connected tubulars; and \n i. a display in electronic communication with the computer processor for presenting measured and computed values for rotating tubulars in real time, and wherein the upper pipe wiper and the lower pipe wiper simultaneously ensure each laser beam has a debris-free and fluid-free reading surface for each rotating tubular, and wherein the system is configured to measure a plurality of rotating tubulars, each tubular rotating in the center hole and in the wellbore during drilling.
