Description

CONNECTION MODULE FIELD OF THE INVENTION

[0001] Descriptive report of patent for the invention of a connection module, whose concept is based on interlockable parts, allowing different combinations of sensors, without the use of external derivations in the power and power supply cable.

SUMMARY OF THE INVENTION

[0002] The optimization of production in oil wells requires the interpretation of data from different sources, such as measurements acquired in real time in the processing plant and sampling, for the purpose of characterization of reservoirs in the early stages of field development.

[0003] In this context, continuous measurements carried out in producer and injector wells are valuable sources of information. Through pressure and temperature records, among others, in different wells, reservoir parameters - such as transmissibilities and communication between wells - can be inferred.

[0004] Likewise, these parameters provide subsidies for monitoring the condition of the well for production or injection, allowing the identification of damage or stimulation of wells.

[0005] In marine wells, continuous recordings of pressure and temperature are derived from instruments permanently accommodated in the production (or injection) column - called "Permanent Downhole Gauges" (PDG).

[0006] Due to the complexity and costs involved in installing a monitoring system, of which PDG is a part, as well as the importance of this system to remain operational, the reliability of this system including the sensors and their connections must be high enough in order to guarantee a useful life, ideally, as long as that of the well. A commonly used method to increase the reliability of systems is the use of redundant elements, such as sensors, electronic components and others. Today's leading well operators require pressure and temperature sensors, as well as other well equipment, to be redundant.

[0007] Today it is known that a significant part of failures occurs in the installation process, electrical connections of the system.

TECHNICAL BACKGROUND

[0008] Due to the importance of monitoring the characteristics of an oil well, the current permanent sensors, for the most part, become a technological barrier to production optimization, since failures in these sensors cause loss of monitoring of important variables, such as pressure and temperature, among others, in production control, especially in intelligent well completions.

[0009] This problem causes difficulties in the management of oil well operations, interfering with production, in addition to which, in an extreme situation, there is a need for intervention, through wire (wireline), to obtain these data.

[0010] Thus, additional expenses are required due to the low reliability of current sensing solutions.

• - Necessidade de muitas conexões rosqueadas ou soldadas para o monitoramento simultâneo de pressão e temperatura da coluna de produção e da região anular, gerando pontos de falha que, por consequência, reduz a confiabilidade do sistema;
• - Necessidade de grande número de componentes, como, por exemplo, peças estruturais, vedações e conectores elétricos, para realizar o sensoriamento e derivação da alimentação; itens esses que impactam, de forma considerável, o custo do equipamento, uma vez que devem ainda suportar o ambiente severo encontrado de um poço de petróleo;
• - Necessidade de maior dispêndio de tempo na montagem do equipamento, tanto em laboratório como na instalação do sistema de completação, devido à quantidade de peças, cujo custo tem peso elevado, em função de todos os riscos envolvidos com a operação em campo;
• - Impossibilidade de se ter mais de dois sensores instalados no mesmo equipamento, sem a necessidade de mais de uma derivação externa dos cabos de alimentação;
• - As técnicas atuais somente permitem a instalação com cabos de alimentação de via única, ao contrário da presente invenção que permite tanto a instalação para cabos de uma via como de duas vias, além de abrir a possibilidade de instalação para cabos de várias vias, conforme será descrito a seguir.

[0011] It is possible to list some problems in current techniques such as:

• - Need for many threaded or welded connections for simultaneous monitoring of pressure and temperature of the production column and the annular region, generating points of failure that, consequently, reduce the reliability of the system;
• - Need for a large number of components, such as structural parts, seals and electrical connectors, to perform the sensing and power derivation; items that have a considerable impact on the cost of the equipment, since they must also withstand the harsh environment found in an oil well;
• - Need to spend more time in assembling the equipment, both in the laboratory and in the installation of the completion system, due to the number of parts, whose cost is high, due to all the risks involved with the operation in the field;
• - Impossibility of having more than two sensors installed in the same equipment, without the need for more than one external derivation of the power cables;
• - Current techniques only allow installation with single-way power cables, unlike the present invention, which allows both the installation for one-way and two-way cables, in addition to opening the possibility of installation for multi-way cables, as will be described below.

[0012] There are several solutions in the market for sensing oil wells, offered by large companies in the sector to meet demands.

[0013] The Halliburton company has a family of pressure and temperature sensors capable of operating in an environment with temperatures up to 200 °C and measuring up to 30,000 psi of pressure.

[0014] The “Single Pressure/Temperature Sensor” is capable of monitoring the temperature and pressure up to 25,000 psi of only one of the regions, the production column or the annular region; the "Single Pressure/Temperature Sensor + Feedthrough" has the same functionalities as the previous one and includes a system in which the derivation is made in the internal region of the sensor, allowing the passage of energy to a subsequent equipment, while the "Dual Pressure/ Temperature Sensor” is capable of simultaneously measuring pressure up to 25,000 psi and temperature in the annular region and in the production column.

[0015] The "Dual Pressure/Temperature Sensor + Feedthrough" has functionality similar to the "Dual Pressure/Temperature Sensor", and includes the internal bypass system to the sensor casing, which allows feeding the next equipment without equipment for a bypass external.

[0016] The “Dual Pressure/Temperature Sensor Fully Redundant” is capable of monitoring pressure up to 30,000 psi and temperature in both the annular and production column regions, including redundancy system in the monitoring.

[0017] The “Dual Pressure/Temperature Sensor Fully Redundant + Feedthrough” also monitors the pressure and temperature of both the annular and production column regions, with a maximum pressure of 25,000 psi, and includes an internal feed bypass system similar to the Previous “Feedthrough” sensors.

[0018] Further specifications for these sensors can be obtained from https://www.halliburton.com/content/dam/ps/public/wd/contents/Data_Sheets/w eb/H07001_ROC-Gauges.pdf?node-id=hfqel9vx&nav= enUS_completions_public.

[0019] The Schlumberger company also presents solutions for monitoring from a single region of the oil well, to both the annular and production column regions with an internal supply bypass system.

[0020] The “WellWatcher Sapphire” sensor, illustrated in Figures A, features a fully welded assembly and the ability to monitor pressures up to 10,000 psi and maximum temperatures of 110 °C.

[0021] The "WellWatcher Quartz LT" has the ability to monitor an oil well region with a pressure limit of 10,000 psi and 130 °C maximum temperature, for sensing other regions of the well, or supplying subsequent equipment, a rectangular-shaped piece is required where the power is bypassed, where, on one side, the power cable is connected and this is bypassed to the pressure and temperature sensor and to the other output, as illustrated in Error! Reference source not found. 1B.

[0022] Finally, the "WellWatcher Quartz Extend", illustrated in Figure 1C, is capable of monitoring pressures up to 20,000 psi and a maximum temperature of 150 °C; in addition, it is capable of simultaneously sensing the annular region and the production column with an internal power bypass system, allowing the power of subsequent equipment without external bypass equipment.

[0023] The Weatherford company also has pressure and temperature sensors with pressure and temperature limits of 30,000 psi and 300 °C in optical sensors and 25,000 psi and 200 °C in quartz sensors.

[0024] As illustrated by
- In Figure 2A, the available instruments are only able to monitor one of the regions of the oil well in the case of the single sensor, on the left in the Figure. The sensor in Figure 2B is capable of monitoring the annular region and the production column, using a power bypass piece, but it does not allow for feeding subsequent equipment. As for the sensor in Figure 2C, which illustrates an alternative assembly in Figure 2B, there is only the possibility of monitoring one of the regions of the well, and the derivation allows the acquisition of data at the same time as the supply of the next equipment.

[0025] DataCan's sensors feature welds that provide an airtight environment inside their casings, and are specified for pressures up to 20,000 psi and maximum temperatures of 150 °C.

[0026] The sensor "Multi-Gauge Passthru Quartz Tool", illustrated in Figure 3A, is capable of monitoring several parameters of the well, such as pressure, temperature and vibration, and has a communication port with the well environment, having a derivation " Y” inside its casing, allowing the energy to pass through to other equipment.

[0027] The "Dual Quartz Pressure Gauge", illustrated in Figure 3B, allows the simultaneous sensing of the pressure and temperature of the annular region and the production column, also having the possibility of reading the vibration for both regions.

[0028] The company Pioneer Petrotech offers some pressure and temperature sensors capable of monitoring pressures up to 25,000 psi and temperatures up to 200 °C, whose sensing requires a central piece, where the derivation of the energy received by the power cable occurs, which allows obtaining data for the region of the production column and the annular region, in addition to the supply of a next equipment, as illustrated in Error! Reference source not found.

[0029] Geopsi company pressure and temperature sensors are capable of monitoring pressures up to 25,000 psi and temperatures up to 200 °C using QuartzdyneTM sensors.

[0030] The sensors "Dual Inline Quartz Gauge" and "Dual Quartz Gauge" monitor one of the regions of the oil well, annular or production column, and have the ability to install up to 10 sensors in series on a single power cable, as illustrated in FIGS. 5A and 5B, respectively.

[0031] The applicant has a solution for the permanent sensing of the pressure and temperature of the production column and annular region of an oil well, illustrated in Figure 6, which incorporates the same problems of the previous techniques, that is, with a high number of structural parts, seals, welds and electrical connectors that are required for the same purpose.

[0032] Thus, it is desirable to propose a connection module that operationalizes the concept of pluggable parts, allowing different combinations of different types of sensors, arranged in series, without the use of external derivations in the power cable and supply of energy.

FUNDAMENTALS OF THE INVENTION

[0033] The connection module of the present invention is responsible for distributing the energy received from the surface, or from any other location, for powering a sensor, adjacent to the connector and, through "Feedthrough" conductors, supplies current to another disposed sensor subsequently in series.

[0034] The concept of the connection module of the present invention incorporates, on the one hand, an entry point of electrical energy, coming from the surface or from any other location, having, inside the connection module, a shunt conductor, responsible for distributing the electrical energy received at output points, with at least one sealing ring being provided in the external region of the body of the shunt conductor, working as an internal sealing barrier, in addition to the welds and seals in the connections of the external casing, in order to maintain the integrity of the sensor electronics.

[0035] On the opposite face of the shunt conductor there are radially distributed holes, through which the "Feedthrough" conductors, which are electrically conducting rods coated with insulating material, pass to conduct the current to another shunt conductor, which transmits electrical energy to other sensors mounted in series (whether or not part of the same tool), or to the next production zone. The presence of the bypass conductor also allows several sensors to be mounted in series within the same mechanical enclosure, at least two for external measurements and at least two for internal measurements. In this way, it is possible to meet the redundancy requirements for measuring pressure and temperature, or other quantities, currently required by well operators.

[0036] The electrical current is supplied to the system through a commercial power connector, with at least one pin, and is distributed, through the shunt conductor, to the "Feedthrough" conductors, which may or may not have cylindrical geometry , which, in turn, conducts the electrical energy to the subsequent shunt conductor, also having, for the mechanical support of the "Feedthrough" conductors, with the function of guiding the conducting rods and limiting vibrations, an anti-vibration coating, formed by a tube of insulating material that also covers the sensor, likewise limiting its vibrations.

[0037] To allow "Feedthrough" conductors to conduct electrical energy between the associated bypass conductors, while allowing, for example, the sensing of the pressure and temperature of the production column and the annular region of a well, is A "Feedthrough" interface is used, assembled with "Feedthrough" conductors and two sensors arranged, each at one end, and, in the non-limiting example of the present embodiment, the sensors are threaded and welded, in addition to the passages of the "Feedthrough" conductors, which are circular in the branch conductors of the present embodiment, may alternatively have another shape, depending on the geometry of the "Feedthrough" conductor rods.

[0038] The cross section of the "Feedthrough" interface is not limited to cases in which the communication of the sensors with the production column and annular region is necessary, as in the case of pressure and temperature sensing, and may alternatively have the two sensors in communication with only one of the regions, when redundancy in the same tool is desired.

[0039] The "Feedthrough" interface may also not have direct communication holes with the well, in cases where you want to monitor, for example, the vibrations of a well, or take advantage of vibrational energies to collect electrical energy, through piezoelectric materials, for example.

• - Redução do número de peças estruturais, soldas, vedações e componentes elétricos/eletrônicos, uma vez que a derivação da alimentação é interna ao corpo do sensor, por meio do condutor de derivação e da interface “Feedthrough”, sem necessidade de uma peça externa com esse propósito, sendo os sensores montados alinhados coaxialmente;
• - Facilitar a montagem em laboratório e instalação em campo, devido à redução de componentes do equipamento, tornando-a, portanto, mais rápida;
• - Redução de custos com a produção do equipamento, devido à redução de componentes, dentre estes peças em ligas metálicas de níquel, tais como Inconel 718, e conectores elétricos para alta temperatura e alta pressão, menos vedações elastoméricas e menos locais de solda, que devem ser especiais para ambiente altamente corrosivo (contendo H2S e CO2);
• - Aumento na confiabilidade do equipamento, devido à redução de conexões rosqueadas e soldadas, havendo menos pontos de possível falha (vazamento e/ou ruptura), além de permitir configurações com redundância de sensores e dispositivos eletrônicos em geral;
• - Montagem modularizada, possibilitando instalar diversas combinações de sensores alinhados no mesmo equipamento, por exemplo, dois sensores de pressão e temperatura e um sensor de vibração;
• - Possibilidade de combinação do condutor de derivação e da interface “Feedthrough” como simples emenda de cabos.

[0040] The advantages of the bypass module of the present invention, which combines the bypass conductors, the "Feedthrough" conductors and the "Feedthrough" interface, for application in sensors for oil wells are:

• - Reduction in the number of structural parts, welds, seals and electrical/electronic components, since the power bypass is internal to the sensor body, through the bypass conductor and the "Feedthrough" interface, without the need for an external part for that purpose, the sensors being mounted coaxially aligned;
• - Facilitate laboratory assembly and field installation, due to the reduction of equipment components, thus making it faster;
• - Cost reduction with the production of the equipment, due to the reduction of components, among these parts in nickel metal alloys, such as Inconel 718, and electrical connectors for high temperature and high pressure, less elastomeric seals and fewer solder locations, which must be special for highly corrosive environment (containing H2S and CO2);
• - Increased equipment reliability, due to the reduction of threaded and welded connections, with fewer points of possible failure (leakage and/or rupture), in addition to allowing configurations with redundancy of sensors and electronic devices in general;
• - Modularized assembly, making it possible to install several combinations of sensors aligned in the same equipment, for example, two pressure and temperature sensors and a vibration sensor;
• - Possibility of combining the lead conductor and the “Feedthrough” interface as a simple cable splicing.

PREFERRED DESCRIPTION OF THE INVENTION

[0042] As shown in Figures 7, the branch module includes a branch conductor (1) that has, on one side, an input (2) of electrical power supply, coming from the surface or from any other location , by power connector (C), of at least one pin, said lead conductor responsible for distributing the electrical energy that enters on the one hand, through the output points on the opposite side of said lead conductor, being a central one (3 ) to supply the sensor (S), and the peripherals (4), radially distributed, for the passage of the "Feedthrough" conductors (5), which are electrically conductive rods coated with insulating material, fit in said peripheral output points, and which conduct the electrical current to another shunt conductor, which transmits it to the next production area, or to other sensors mounted in series, forming part of the same tool, with at least one sealing ring (6) being provided in the external region. outside of the branch conductor body, functioning as an internal sealing barrier, in addition to the welds and seals in the external casing connections, in order to maintain the integrity of the sensor electronics.

[0043] Figure 8 illustrates the shunt conductor fed by the power connector (C) of a conventional pin, with the electrical current being distributed, through the shunt conductor, to the "Feedthrough" conductors (5), which may have or not cylindrical geometry, and which, in turn, conduct the electrical energy to the subsequent shunt conductor, and to provide mechanical support to the "Feedthrough" conductors, in addition to guiding the conductive rods and limiting vibrations, a support coating is provided. anti-vibration (7), which is a tube of insulating material that also covers the sensor, limiting its vibrations in the same way.

[0044] To allow "Feedthrough" conductors (5) to conduct electrical energy through two associated bypass conductors (1), while allowing, for example, the sensing of the pressure and temperature of the production column and the the annular region of a well, the "Feedthrough" interface (8) is used, mounted with the "Feedthrough" conductors (5) and the sensors (S) arranged at each end, said sensors may be threaded and welded, but not limited to this type of connection, as illustrated in Figure 9.

[0045] The passages (4) of the conductors "Feedthrough" (5) can be circular, or any other, depending on the geometry of the conductor rods that cross the interface "Feedthrough" (8).

[0046] Figure 10 illustrates the cross section of the "Feedthrough" interface (8) for cases where communication of the sensors with the production column and annular region is necessary, as in the case of pressure and temperature sensing, which are obtained through the communication sockets (9a and 9b) of these regions, however, the so-called "Feedthrough" interface is not limited to this condition, and may, alternatively, have the two sensors in communication with only one of the regions, when desired redundancy in the same tool, as illustrated in Figure 10A and Figure 10B.

[0047] Figure 10C illustrates the cross section of the "Feedthrough" interface (8), for cases where the communication of the sensors with the production column and annular region is not necessary, as in the case of sensing, for example, of vibrations from a well, or harnessing vibrational energies to collect electrical energy, through piezoelectric materials, for example.

[0048] Example of application of the shunt conductor assembly (1), "Feedthrough" conductors (5) and "Feedthrough" interface (8) is illustrated in Figure 11, where a PDG sensor for monitoring the pressure and temperature of the production column and annular region in the same tool, through a power connector (C) of one pin, which receives electrical energy through a "TEC" (encapsulated tubing cable - not illustrated) connected to the derivation conductor (1), responsible for conducting electrical power to the column pressure and temperature sensor (S), with the "Feedthrough" conductors (not shown) coupled to the bypass conductor (1), crossing the "Feedthrough" interface (8), conducting current, and that they connect to the bypass conductor (1) that supplies the pressure and temperature sensor (S) of the annular and the supply connector (C) of the next zone. This assembly allows the tool to fulfill its functions of monitoring the variables of the well, providing electrical energy to the tools and subsequent equipment, without the need for an external bypass.

[0049] Figure 11A illustrates the solution of the present invention that fulfills the same features, but with the arrangement where redundant sensors are mounted in the same metallic casing as described in Fundamentals of the Invention. The image shows four pressure and temperature sensors (S) connected in series, two of which are directed to ring measurements and two to column measurements, using two "Feedthrough" interfaces (8), in the illustrated configuration in Figure 10. This arrangement is made possible through the use of two branch conductors (1), mounted in a mirror, connected through the power input (2), or through a branch connector with constitutive arrangement equivalent to the one described. This mounting configuration increases the reliability of the monitoring system and meets the technical and operational requirements often required for downhole applications.

[0050] Figure 11B illustrates the solution of the present invention that fulfills the same features presented in the previous paragraph, but with the sensors (S) for measurements in the production column mounted in the "Feedthrough" interface (8), in the redundancy configuration of Figure 10A, and the sensors (S) for measurements in the annular region mounted on the “Feedthrough” interface (8), in the redundancy configuration of Figure 10B.
