Laser measuring system for joints of pipes

摘要

A laser measuring system for continuous measurement of at least one join of pipe being inserted into or removed from a wellbore. The laser measuring system can have a laser housing with a laser surface velocimeter. The laser housing with a laser arm can be connected to a support member with an upper mounting member and an upper rubber pipe wiper and a lower plate with a lower rubber pipe wiper. The laser surface velocimeter 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. The laser beam used to detect and calculate length and quantity of joints of pipe moving past the laser beam transmitting the information to the computer processor real time.

1. A laser measuring system for continuous measurement of at least one joint of pipe being inserted into or removed from a wellbore, the laser measuring system comprising:
a. a support member having a center hole aligned with the wellbore, the center hole configured to receive the at least one joint of pipe, as the at least one joint of pipe is into and out of the wellbore, the support member having a first laser beam opening formed in the support member penetrating the center hole, the support member connected between an upper mounting member and a lower plate; b. an upper rubber pipe wiper with a upper wiper opening connected to the upper mounting member and a lower rubber pipe wiper with a lower wiper opening connected to the lower plate for cleaning the at least one joint of pipe between the upper mounting member and the lower plate; c. a laser arm comprising a second laser beam opening aligned with the first laser beam opening, the laser arm connected to the support member at an angle; d. a laser housing comprising a third laser beam opening, the third laser beam opening aligned with the second laser beam opening, the laser housing connected to and aligned with the laser arm; e. at least one protection wall mounted within the laser arm having an aperture aligned with the first laser beam opening, the second laser beam opening and the third laser beam opening; f. a laser surface velocimeter connected to a power supply, the laser surface velocimeter positioned in the laser housing and oriented to project a laser beam through the first laser beam opening, the second laser beam opening and the third laser beam opening sequentially, the laser surface velocimeter configured to:
(i) measure lengths of the at least one joint of pipe being run into and out of the wellbore forming a length of each joint of pipe;(ii) count the at least one joint of pipe being run into and out of the wellbore forming a quantity of joints of pipe; and(iii) calculate a total length of connected joints of pipe; g. a computer processor in communication with the laser surface velocimeter; h. a data storage in communication with the computer processor, the data storage comprising:
(i) computer instructions for instructing the computer processor to receive and store from the laser surface velocimeter:
1. the length of each joint of pipe;2. the quantity of joints of pipe; and3. the total length of connected joints of pipe; and i. a display in communication with the computer processor for presenting the length of each joint of pipe, the quantity of joints of pipe, and the total length of connected joints of pipe in real time, wherein the upper rubber pipe wiper and the lower rubber pipe wiper simultaneously with the at least one protection wall ensure the laser beam has a debris-free and fluid-free reading surface on the at least one joint of pipe.
