Description
Technical Field
The present invention relates to the oil, gas and mining industries, and in particular to a method of reading information from RFID tags mounted on oil and gas drilling equipment and may be used to determine the depth, speed and residence time of drill pipe in a borehole during drilling and other lifting operations.
The invention has industrial applicability.
Background
Drill strings for oil and gas drilling are composed of various types of pipes. Deep wells typically have more than 600 drill pipe joints in the wellbore; in addition to drill pipes, the drill string may include tools such as weighted drill pipes, reamers, stabilizers, joint adapters for various threaded connections, safety valves, and special tools for logging.
Drill pipe is the main part of the drill string designed to enter the borehole and lift the rock breaking tool, transmit rotation, create axial loads on the tool, and transport drilling mud to the bottom of the hole. They also account for a significant portion of all oil and gas production costs. It is therefore important to have an effective means of controlling the entire life cycle of the drill pipe, including its operation directly at the drilling machine.
Currently, RFID technology is being used by companies such as Schlumbrger, petrobas (petroleo brasileiro s.a.), weatherfordInternationalLtd, chinaPetroleum & Chemical Corporation (Sinopec), horizons ofgrowthllc, and the like. The application of RFID technology is to assemble an RFID tag on each tube that carries unique information about that particular tube.
Reading information from the RFID tag at the necessary moments can allow for accurate calculation of depth position, movement speed and time of the drill pipe in the borehole during drilling. The device for radiating and receiving radio waves-RFID antenna and the RFID scanner with data recording, storage and memory system are placed in the borehole directly below the turntable. Radio frequency identifiers (RFID tags) are installed in drill pipe and other mechanisms and accessories within the drill string. The depth, travel rate and time spent by the drill pipe or other tool in the hole is determined by recording the RFID tag, lowering or lifting of the drill string. Logging is performed when the portion of the drill pipe carrying the RFID tag passes the RFID antenna.
The depth and time of the drill pipe in the borehole is calculated in real time by mathematical algorithms in the ARBI hardware-software system, which records the physical process.
The depth, speed and time of the drill pipe left in the borehole is calculated using the drill string specified by the element, and the calculation is in turn implemented in the software-hardware complex ARBI (russian federal certificate No. 2019661321, 2020617486), when operating on the drill rig in test mode.
Disclosure of Invention
The object of the present invention is to determine the depth position, the speed of movement and the time of the drill pipe in the borehole during drilling and other travel operations.
The present invention implements closed loop drill string control based on RFID tags to calculate the depth, speed and time of the drill string in the borehole. The measurement and calculation is online, automatic, performed without operator intervention.
The essence of the invention is illustrated in fig. 1, which schematically shows the principle of operation of the device, providing an implementation of the proposed method.
This object is achieved by the fact that: the proposed method comprises a device that can record the exact timing of the entry of the drill pipe into the well and the lifting of the drill pipe out of the well for each individual pipe in the string.
The pipe in the drill string is marked with an RFID tag at a specific location, a measurement system consisting of an RFID antenna and an RFID scanner reads the tag, and dedicated software (ARBI software) controlling the measurement processes the data and performs calculations.
The essence of the method of determining the depth of position, the speed of movement and the time of the drill pipe in the borehole is as follows.
The RFID antenna is mounted at the wellhead directly below the turntable, and the RFID logging, storage and processing system is connected to the antenna in the form of an RFID scanner. Radio frequency RFID tags are placed in the mechanisms and elements that make up the drill string, with the aid of which the recording system, RFID antenna and RFID scanner determine the exact time the tagged pipe passes the antenna. When a drill pipe with an RFID tag passes the RFID antenna, the signal received from the RFID tag is transmitted to a data logger (RFID scanner) that is connected to a local server with dedicated "ARBI" software that calculates the depth of each drill pipe, the time the drill pipe is in the hole, and the speed of the drill pipe in the hole based on the data received from the tag.
The nature of the algorithm for calculating the speed of the drill string during drilling or other trip operations is to calculate the time interval between successive passes of RFID tagged, registered passes of a known length of drill pipe in the drill string past the RFID antenna. The current depth of a particular drill pipe into the well is determined by sequentially summing the lengths of drill pipes subsequent to the drill pipe whose depth was calculated. The current depth of the drill pipe rising from the borehole is determined in the reverse order by continuously subtracting the length of the previous drill pipe from the borehole from the depth of the pipe being lowered. The time the drill pipe is in the borehole is determined by counting the time interval between the descent and ascent of the same RFID tag past the RFID antenna.
If the length and time are known, the speed of the drill pipe, and thus the speed of the entire drill string, is easily determined.
The method provides information about the depth of position, residence time and speed of each drill pipe in the well and thus provides all of these parameters for the drill string as a whole.

Detailed Description
An implementation of the invention is described below with reference to the accompanying drawings.
In the wellhead 12 (fig. 1, 3, 4), an RFID antenna 2 (fig. 1, 2, 3, 4) is mounted directly below the rotary table 8 (fig. 1, 2, 3, 4), the RFID antenna 2 (fig. 1, 2, 3, 4) being connected to the system for recording, memorizing and processing information in the form of an RFID scanner (fig. 1, 2, 3, 4). The mechanisms and elements comprising the drill string 1 (fig. 1, 3, 4) are equipped with radio frequency RFID tags 3 (fig. 1, 2, 3, 4), and the RFID scanner recording system 5 (fig. 1, 2, 3, 4) determines the length and time of passage of the marked drill pipe 1 (fig. 1, 2, 3, 4) by means of the radio frequency RFID tags 3.
As the drill pipe 1 (fig. 1, 2, 3, 4) with the RFID tag 2 (fig. 1, 2, 3, 4) passes the RFID antenna 3 (fig. 1, 2, 3, 4), the signal received from the RFID tag 2 (fig. 1, 2, 3, 4) is transmitted into the data logger 5 (fig. 1, 2, 3, 4), the signal received from the RFID tag 2 (fig. 1, 2, 3, 4) is transmitted to the data logger 5 (fig. 1, 2, 3, 4) associated with the local server 7 (fig. 2), a dedicated software "smart card reader" (fig. 3, 4) with dedicated software "ARBI" (not shown in the drawings), wherein the software "ARBI" calculates the depth of descent (fig. 1, 2, 3, 4) in relation to the drill pipe 1, the time of the drill pipe 1 (fig. 1, 2, 3, 4) in the drill hole, and the data logger 5 (fig. 1, 3, 4) associated with the dedicated software "ARBI" (fig. 3, 4) in the drill pipe 1, 3).
The nature of the algorithm to calculate the drill pipe speed during drilling or other lowering operations is to calculate the time interval between registration of successively passing drill pipes with PFID tags 2 (fig. 1, 2, 3, 4) as part of the drill string past RFID antenna 3 (fig. 1, 2, 3, 4). The current depth of the drill pipe 1 (fig. 1, 2, 3, 4) which is lowered into the borehole is determined by sequentially summing the lengths of the drill pipes after the drill pipe whose depth is calculated. Determining the current depth of the drill pipe lifted out of the borehole in reverse order-by sequentially subtracting the length of the current drill pipe lifted out of the borehole from the depth of the drill pipe lifted out of the borehole.
The residence time of the drill pipe in the well is determined by calculating the time interval between the descent and ascent of the same RFID tag 2 (fig. 1, 2, 3, 4) passing through the RFID antenna 3 (fig. 1, 2, 3, 4). Each drill pipe has a unique RFID tag 2 (fig. 1, 2, 3, 4).
