Description

SPIRAL TUBE APPLICATION HAVING VIBRATION-BASED FEEDBACK

BACKGROUND Exploration, drilling, and completion of hydrocarbon wells are complicated, time-consuming, and costly activities. As such, the hydrocarbon recovery industry often increases access to wells. Specifically, access to a well is important for monitoring its condition and maintaining good health. Such access to the well is often provided by means of well access lines such as a spiral tube.

Well access lines may be designed to provide downhole interventional or monitoring tools. In the case of spiral tubes and other tubular lines, a fluid may also be introduced downhole. A spiral tube is particularly well suited to be driven downhole through a horizontal or tortuous well, to depths of perhaps several thousand feet, by an injector on the surface of the Earth.

When running spiral tube applications, it is common to use various forms of percussion tools to release stuck tools, clean debris, and so on. A drill bit can even be attached to the spiral tube for another drilling application. However, the force that these devices provide and the impact they could have on other devices in the spiral production tube are not normally known. Since these important variables in the applications are unknown, the operators are unsure of the reasons for success or failure in a particular application resulting in an inability to credibly predict whether an application will be successful before allocating resources to it. Although experience has shown that a particular action will succeed in eliminating abnormal behavior when applying spiral tube, because of the unknown nature of the forces acting on the spiral tube, the operators can not say that this action does not constitute a waste of the resources used, that is to say, inefficient.

DETAILED DESCRIPTION

The problems identified in the context are at least partially addressed by systems and methods for adjusting a variable element of a spiral tube application based on feedback. In spiral tube applications, vibrations within the spiral production tube may indicate any number of problems if the vibration characteristics are not within normal operating ranges that constitute a vibration profile associated with the applications. of spiral tubes. Such vibrations can include longitudinal or axial vibration, torsional vibration, and lateral vibration, and identifying problems based on vibration characteristics leads to solutions that can not only increase the efficiency of tube applications spiral but also prevent application failures. Problems can be identified based on feedback from the state of spiral tube applications, and solutions may include adjusting one or more variable elements of spiral tube applications. For example, in a stuck tool application, a variable element such as the flow rate of fluid pumped through the spiral tube can be adjusted by a mechanical control device such as a valve that increases or decreases the flow through opening and closing. respectively. As another example, in a milling application, a variable element such as a bit rotation speed can be set by a mechanical controller such as a bit motor. In this way, many variable elements of many applications can be set. The variable elements can be set in response to an operator command or automatically, i.e. without human intervention, based on the feedback.

The systems and methods described for adjusting a variable element of a spiral tube application based on feedback are better understood depending on the context in which they are employed. As such, FIG. 1 represents a contextual view of a spiral tube environment including a feedback system 100. The system 100 comprises a spiral production tube 54, which may include a spiral tube connected to a downhole module constituted by various fittings 64 and tools 65. The spiral tube is drawn from a spool 52 by a tube injector 56 and injected into a borehole 62 through a seal 58 and a blowout block 60. In this way , the spiral production tube 54 is transported along the borehole 62. As illustrated, the borehole 62 is initially vertical. However, as further detailed below, the borehole 64 may be of a wide enough range finally rotating horizontally. In addition, directional drilling can result in a tortuous borehole with many curves and turns.

The spiral tube may be a continuous length of steel, steel alloy, stainless steel, composite tube, or other suitable metallic or non-metallic material sufficiently flexible to be wound on the coil 52 for transportation and coil 52 itself may be located on a spiral tube truck for mobility purposes. Because of the relative lack of seals, it is advantageous to use a spiral tube when pumping chemicals downhole.

In the borehole 62, the spiral production tube 54 comprises a supervisory fitting 64 and one or more tools 65 connected to the spiral tube 54 which constitute the downhole module. The supervisory connector 64 may control communication between wellhead and downhole elements, and may also control communication between downhole elements such as one or more tools 65 by providing a clock, a source of information, and a source of information. power supply, and a common communication bus, and the like. The tools 65 may be fittings, or other sections of the spiral production tube 54, which perform functions particular to a spiral tube application. For example, in a perforation application, the tools 65 may comprise a perforation tool comprising perforators and the like. As another example, in a milling application, the tools 65 may include a milling tool comprising a drill bit. Spiral tube applications can also be performed at sea.

The system 100 also includes a data processing system 66, which may be connected to a wellhead interface 67 at the surface by a wired connection or a wireless connection, and may periodically obtain measurement data from the interface wellhead 67 depending on the position and / or the time. The wellhead interface 67 may communicate with the supervisory fitting 64, the tools 65, and / or the computer system 66 and may allow communication between wellhead and downhole elements. For example, mud pulse telemetry, acoustic telemetry, and the like can be used to provide communications from the supervisory connector 64 to the wellhead interface 67. Among other things, the data processing system 66 processes the data received from the wellhead interface 67, or from the supervisory connector 64 and / or the one or more tools 65 directly, and generates a representative display for the perception of the operator. Software (represented by an information storage medium 72) may be executed on the data processing system 66 to collect the data and organize it into a file or database stored on a non-information storage medium transient. Specifically, one or more processors connected to a memory may execute the software and perform any appropriate action described below. The software may respond to user intervention via a keyboard 70 or other intervention mechanism to display data such as an image or a movie on a monitor 68 or other output mechanism. The software can process the data to optimize feedback spiral tube applications as described below, and the data processing system 66 can send control signals to adjust a variable element based on the feedback. In at least one embodiment, the data processing system 66 is located downhole within a housing adapted to protect the system 66 from the difficult downhole environment. In another embodiment, both surface and bottomhole processors can work together or independently to obtain, store, and process measurement data. The supervisory connector 64 and / or the tools 65 may include these downhole processors.

The system 100 further comprises one or more vibration sensors 90 connected to the spiral production tube. As shown, the vibration sensors are located on the supervisory fitting 64, the tool 65, and the spiral tube, but one or more vibration sensors may be located anywhere on the spiral production tube 54. For example the vibration sensors 90 may be located on each side of a downhole element, as a particular tool, to locate the direction in which vibration waves are moving at that location of the spiral production tube. The vibration sensors 90 measure vibrations within the coiled production tube 54 upon application of coiled tubing by measuring vibration wave characteristics moving through the tube 54. For example, amplitude, frequency, and the like can be measured. A vibration sensor 90 includes a triaxial accelerometer that captures three directional components of the vibration waves (one for each coordinate axis), a piezoelectric accelerometer, magnetometers, Hall effect devices, and the like. The vibration sensors 90 can measure or monitor lateral vibration, longitudinal vibration, and torsional vibration.

By measuring the vibration characteristics, downhole conditions such as stress, load, frictional resistance, and the like can be monitored on a continuous basis. The vibration sensors 90 may be used to collect and relay vibration measurement data at the wellhead interface 67 and / or the data processing system 66 for an analysis of current conditions during an application of spiral tube. Depending on the application of coiled tubing, vibration sensors 90 at different locations will be relevant for monitoring downhole conditions, and irrelevant sensors 90 may be excluded from comparison with the vibration profile. For example, in a milling application, the vibration sensor 90 closest to the distal end of the spiral production tube 54 will be the most relevant, while in a perforation application, the vibration sensor 90 closest to the perforator will be the most relevant. In this way, the data reported by the vibration sensors 90 can be weighted according to their relevance. The weight can affect the relevance attributed to the vibration measurement data when the vibration measurement data is compared to a vibration profile. For purposes of illustrating the concepts of the present invention, the relative terms of vibration measurements of "low", "medium" and "high" acceleration are used in the present invention. These terms are not intended to reflect any specific values, since the quantitative measurements will be recognized by those skilled in the art to be variable depending on the spiral production tube used and the components thereof. For example, in terms of actual forces experienced, in many operating situations, the axial acceleration on the spiral production tube 54 is generally of the order of 0.1 g; but it can exceed 100 g for short time intervals (for example, a few milliseconds); and the side impact may exceed 1000 g. Therefore, in absolute forces, a weak vibration could be characterized, for example, by a mean vibratory axial vibration level of less than about 0.1 g with peaks of the order of 1 g for a few milliseconds, and a transverse vibration -axial less than about 1 g with peaks no greater than 10 g. These thresholds may change depending on the application.

Similarly, a high vibration could be characterized, for example, as a vibration in which either the axial vibration exceeds 1 g on average, having acceleration peaks exceeding 100 g, (for example, for 1 or more times per second ), the lateral vibration exceeds 10 g on average, or the lateral vibration has peaks exceeding a few hundred g one or more times per second. A vibration of average level could then, in this example, be characterized by any value between these two states. These thresholds may also change depending on the application. For the sake of clarity, however, the above examples are only examples, and are only representative of absolute forces; and actual measured vibratory forces can thus be substantially different from the exemplary values, depending on the characteristics of the measuring system and spiral production tube 54. The thresholds and base values used in the present invention can be determined from the modeling, prior experience, or measurement when applying spiral tube itself.

Considering a general application of coiled tubing (specific spiral tube applications are described below), the one or more processors of the data processing system 66 obtain vibration measurement data from the vibration sensors 90 (e.g. , located on the downhole module) and provide feedback when applying spiral tube based on the vibration measurement data. The one or more processors may continuously provide, over a period of time, feedback based on the change of vibration measurement data resulting from the adjustment of the variable element. Specifically, the system 100 includes a mechanical controller, and the controller adjusts a variable member of the spiral tube application based on the feedback. The mechanical controller can be operated mechanically, electrically, hydraulically, and the like. The controller can continuously adjust the variable element based on the feedback until the vibration measurement data conforms to a profile associated with the spiral tube application. For example, in a stuck tool application, a mechanical control device such as a valve 61 increases or decreases the fluid flow through opening and closing respectively. Although such a valve 61 is shown downhole in the present invention, the valve may also be located at any location along the path in which this fluid flows even to the surface. A vibration sensor 90 near the valve reports a low vibration that is outside the range of the vibration profile of a stuck tool application. Then, the valve 61 opens wider to increase the fluid flow to help release the jammed tool, and the vibration measurement data is again compared to the vibration profile. If the vibration sensor 90 reports data within the vibration profile, then no further action needs to be taken. If the vibration sensor 90 reports data still outside the vibration profile, the valve 61 can be further expanded until the vibration profile threshold is reached for that particular sensor. Such a setting can take place automatically, that is to say, without human intervention. In at least one embodiment, the feedback takes place in real time.

Some examples of spiral tube applications are milling, span extension, release of a stuck tool, debris cleaning, perforation, formation fluid detection, and the like. During milling operations, a milling bit or similar downhole tool on the spiral production tube 54 is used to cut and remove equipment from the equipment or tools located in the borehole. As the spiral tube advances to the bottom of the well, it encounters a frictional resistance while continuing the advancement. Finally, this resistance can stop the continuous advancement of the spiral tube. This resistance can be identified by a vibration sensor 90 detecting a sinusoidal buckling in the vertical section of the borehole which eventually rises to the helical buckling level at the bend or heel of the borehole if it transitions into a lateral section. That is, vibrations that are prevalent along the feed tube start to stop when the tube becomes stuck and becomes motionless due to buckling. This net decrease in amplitude, greater than about a 10% threshold, can be detected by a vibration sensor 90 located at the downhole module. Therefore, a mechanical control device such as an injector can adjust the force on the spiral production tube 54 until the vibration sensor 90 indicates that the vibration measurement data is again within the threshold. In this way, the feedback can also include milling efficiency, the variable element can include the force on the spiral production tube, the bit rotation speed, the bit force, the bit type, or the bit. flow rate of fluid pumped through the spiral tube, and the mechanical control device may comprise a motor connected to the bit, a bit selector that automatically switches the bits, or a valve respectively. Specifically, these mechanical control devices can adjust the variables so that vibration measurement data is located within a milling vibration profile.

Fig. 2 is a partial contextual view of the feedback system 200 in spiral tube environments illustrative of stuck tool and debris cleaning applications. For the sake of clarity, the representation and description of the data processing system are not repeated. When attempting to break into a borehole 10, an understanding of the vibratory and load forces can provide the operator to the surface with information to avoid situations that would cause the cutting tool 22 to jam. , and can also provide information on targeting debris with a cutting tool 22. For example, a whipstock 20 can be set to deflect the spiral production tube 16 so that a cutting tool 22, including a drill bit attached to the end of the spiral production tube 16, targets the debris to be cleaned after cutting by a borehole fluid. Of course, the spiral production tube 16 can also be deflected to also avoid debris. As the flow rate and / or fluid pressure within the spiral production tube 16 increases, a motor 30 is actuated and rotates the cutting tool 22. A hydraulic anchor 38 and a whipstock 20 have been oriented. and set in position using the spiral production tube 16, and sufficient torque created by the motor shears any coupling between the whipstock 20 and the spiral production tube 16. The cutting tool 22 begins to rotate, and is guided at an angle to the borehole 10 by the whipstock 20. While the spiraling production tube 16 is further lowered downhole, the cutting tool 22 intersects at a corner angle. through the casing 14 and creates an inclined outlet 36 therethrough. In some embodiments, the borehole 10 may not be cased, but the cut of an inclined outlet also applies to a non-cased borehole.

By adjusting the flow rate, for example with a valve 82, the actuation of the motor 30 can be set based on vibration measurement data collected by the vibration sensors 90 to release stuck tools and clean the debris. The vibration sensors 90 may be placed at any location along the spiral production tube 16. For example, as shown, the vibration sensors are located on each side of the motor 30 as well as between the motor 30 and the motor. The difference between the measurements obtained by each sensor 90 can be used to identify an abnormal behavior when compared with a vibration profile.

In addition, the system 200 can prevent tools from jamming and release stuck tools. Specifically, the spiral tube injection rate is known, but the actual speed of the downhole module can not be known. However, with the addition of triaxial accelerometers for vibration detection, the actual trajectory of the downhole module can be determined and used as feedback. Here, the mechanical control device comprises the injector, which controls the speed at which the tube is inserted and the force used for insertion. By using feedback, the injector provides a smoother motion through the wellbore and reduces the possibility of sticking. In at least one embodiment, a load cell sensor is incorporated in the feedback to detect when the downhole module has contacted a wellbore obstruction.

FIG. 3 is a cross-sectional view of an illustrative fractured borehole 302. The illustrative borehole 302 has been fully drilled, all drilling equipment has been removed, and the borehole 302 has been cased with a tubing 304 and cemented to support the structural integrity and stability of the borehole 302. The borehole 302 is formed within the target formation 300, which extends beyond the limited range with which it is shown in FIG. 3. The target formation 300 may comprise a plurality of layers, each layer with a different type of rock formation, including the target formation containing hydrocarbons within which the borehole may extend horizontally over a certain distance. The spiral production tube 320 comprises a perforation tool 322 which creates a plurality of perforations 306 through which a fracturing fluid, such as water, is injected under high pressure into the target formation. This high pressure fluid injection creates and opens fractures 308 that extend laterally through the target formation. The high pressure fluid may contain additional chemicals and materials, such as a proppant (eg, sand) that maintains the structural stability of fractures and prevents fractures 308 from collapsing completely. Generally, the horizontal portions of the borehole are drilled generally parallel to the direction of maximum stress, causing fractures 308 to propagate generally perpendicular to the borehole. (As the fractures tend to propagate perpendicularly to the direction of maximum stress, it can be expected that this propagation occurs at a predictable angle from the borehole axis when the borehole is not aligned with the direction of maximum stress.) The overlying and underlying formation layers tend to resist fracture propagation, so fractures tend to spread laterally within the target formation , to a length that depends on the flow rate and the volume of the fracturing fluid injected. Thus, each fracture 308 has a length 310 with respect to the casing 304. Each fracture 308 also has an initial location 314 determined by the perforation position, which is generally measured relative to the distal end of the borehole 302. When regular spacing is employed, the perforations (and hence the fracture initiation points) have a fixed spacing 312 therebetween. Although represented in the figures as generally planar, the actual fractures 308 may be represented as a branching network having a shape and a size which depend not only on the properties of the fracturing injection stream, but also on the nature of the rocks and training materials of the target formation. Therefore, the fracture shapes and sizes are not limited to those shown in FIG. 3. The impact of using a perforator from the perforating tool 322 can be measured by the vibration sensors 90. In addition, determining that the perforator has been used is not without interest because of noisy and chaotic well-bottom conditions. A mechanical controller, such as a lock switch, can prevent other activities from taking place if the vibration sensor 90 has not detected vibrations associated with the use of the punch. For example, activities such as fracturing fluid injection, sand cleaning, hole extraction, and moving to another perforation location can be prevented.

Long reach boreholes refer to long horizontal drill holes. The objectives of an elongated borehole are to reach a wider area from a surface drilling location and to maintain the borehole within a reservoir over a longer distance to maximize its capacity. productivity and drainage. The cleaning of such a borehole, the management of the mechanical loads on the spiral production tube 320, and the management of downhole pressure is a challenge. As such, the vibration sensors 90 can measure characteristics indicative of excessive loads and pressures, such as buckling, and mechanical control devices such as injectors or valves can adjust the force on the spiral production tube 320 or the flow rate. fluid pumped through the spiral tube to attenuate charges, pressure, and the like. In addition, in fluid sensing applications, the feedback may include an indication of a formation fluid entering the borehole 302 based on vibration measurement data from the fluid passing through holes in the tubing. 304 or a production tube. Specifically, the vibration sensors 90 can detect evidence that this fluid enters the borehole at a particular rate based on the impact of the fluid with the spiral production tube 320.

A method 400 of executing a feedback coiled tube application is shown in the flowchart of FIG. 4. At point 402, a coiled production tube is conveyed along a borehole. The spiral production tube can be pulled from a spool by a tube injector and injected into the borehole. The spiral production tube may include tools for performing a particular spiral tube application and vibration sensors for measuring vibration characteristics moving within the spiral production tube upon application of coiled tubing. The tools, together with a supervisory fitting, can be the downhole module of the spiral tube.

At point 404, vibration measurement data is obtained on the basis of vibrations within the spiral production tube. For example, the tools, the supervisory connector, or the data processing system may include one or more processors connected to the vibration sensors, and the one or more processors may be connected to a memory for recording the vibration measurement data. . The vibration measurement data may include vibration characteristics such as frequency and amplitude and may also be obtained as measurements of triaxial vibration components (axial vibration, torsional vibration, and lateral vibration). The vibration measurement data can be obtained from vibrations anywhere along the spiral production tube including the downhole module. For different spiral tube applications, vibration measurement data from different locations will be relevant.

In one embodiment, obtaining vibrations in this manner may include recording a baseline vibration data, for example during a successful spiral tube operation. Thus, indicative future analysis of abnormal conditions can be determined with a higher degree of accuracy by comparing the newly obtained vibration measurement data with the baseline.

At point 406, feedback is provided, when applying spiral tube, based on the vibration measurement data. In at least one embodiment, the vibration measurement data is processed to determine the state of the spiral tube application. For example, the vibration measurement data is compared to the vibration profile for the particular spiral tube application. The profile may include at least one threshold or range of frequency, amplitude, or average energy associated with each sensor that measures vibrations within the spiral production tube. If the data is within the ranges of the profile, at point 408, then normal state feedback can be reported and the process can be terminated.

If the data is not inside the profile, at point 408, then an abnormal state is reported with relevant information about the vibration sensor that is outside the profile, and in at least one embodiment, with suggested solutions based on the characteristics of the anomaly. At point 410, a mechanical controller is used to adjust a variable member of the spiral tube application based on the feedback. The variable element can be continuously adjusted based on the feedback until the vibration measurement data conforms to a profile associated with the spiral tube application. The variable element setting may include adjusting the variable element of the spiral tube application automatically based on the feedback, i.e., without human intervention.

For example, the spiral tube application may include releasing a stuck tool, the feedback may include an indication of movement in the tool, and the variable element may include the force on the spiral production tube, the flow rate fluid pumped through the spiral tube, or the fluid composition pumped through the spiral tube.
