Description
SPECIFICATION
Process and device for installing seismic sensors inside a petroleum production well
The invention concerns a process for installing seismic sensors inside a petroleum production well in order to carry out extremely diverse measure- ments concerning the state of the well, to monitor flow inside the well and also seismic readings enabl ing, in particular, evolution during time of the prod- uction zone to be determined.
Specialists arefamiliarwith the uses of sensors inside welis equipped by production. For example, one of such uses consists of acoustically determining the quality of the borehole cementation coupling with the side wall, the outer pipe column or casing having been disposed therein. One conventional operation carried out in the completion phase of a drilled well consists of descending into it a casing and injecting cement into the ring-shaped space so as to prevent the fluids produced by the well from escaping or migrating through this channel. The quality ofthe cementation, upon which the imperviousness ofthe ring-shaped or annular space depends, is, forex- ample, determined by bringing down into the tubed casing an elongated sensor containing acoustic receivers transmitters disposed at various depths.The transmitted acoustic waves are picked up by various receivers after propagation inside the ring-shaped zone and in particular inside the cement. A comparison of the signals received enables one to determine, for example, which distribution is thoroughly homogeneous.
Another familiar example of use consists of descending inside atubed well a probe containing a large numberofvarious sensors enabling various parameters to be measured, especially acoustic noise, natural radio-activity, temperature, pressure, etc.
Some known examples of the use of sensors in side tubed wells are described in the European patent applications n" 55634 or 98778 and the US patent n0 4.390.878.
The positioning of sensors inside a tubed shaft is suitable for carrying out localized measurements of a nearby ring-shaped zone or for monitoring fluid flowsinsideatubing. But it is not suitable for, for example, determining using seismic methods the evolution of a reservoir in the course of operation.
Seismic records are carried out, particularly by the method known as the vertical seismic profile method (VSP) which includes the reception of waves returned by various underground reflectors by means of a large number of geophones arranged atvarious depths inside a drilled well,these waves having been transmitted by a seismic generator disposed on the surface or possibly inside another well. The implementation of such a method using geophones descended into a fitted-out petroleum production well becomes much more difficult as the connection of the geophones with the environmental formations is made by means of a casing.
The process according to the invention allows four the installation of seismic sensors inside a drilled well equipped for producing petroleum fluids and comprising a cement-sealed casing inside the well. It is characterized in that the seismic sensors are dis- posed inside the casing and thatthey are imbedded inside the cementwhich ensures cementing ofthe casing.
The various seismic sensors are, for example, disposed atvariousdepthsoutsidethecasing and are linked to the surface by electric conducting wires. At each level of depth, a sensor or set of sensors is disposed. When the casing is externally integral with guidance means, the sensors are, for example, secured to these guidance means, the conducting wires being maintained by rings againstthe outerwall of the casing. The guidance means may, for example, include flexible centering blocks. To facilitatethe mounting of the sensors, it is preferable to use dissymmetrical guidance means which move the casing towards one side of the wellbore over one part of its length, the sensors being disposed on the side op polite the casing.It is also possible to use casings, whose transversal section is reduced at at least one part of their length, the sensors being disposed, in the reduced section of the casing, against the casing itself. For coupling of the sensors, a layer of damper material can be inserted between the sensors and the casing.
One advantage of the process ofthe invention is thatthe sensors are directly connected by the cement with the environmental geological formations.
They can then be used to receive the seismic signals due to microseisms produced inside these form- ations during the well production period orthose which are spread from a transmission point on the surface. This location or point may occur on the per pendicular line ofthe well or even over a direction determined in relation to the axis of the well orthe well direction if the latter is contorted. Afurther possible application consists of receiving into a well the seismic signals emitted by a noise source disposed inside another well.
Sound connection between the sensors and the inside of the casing, obtained by the process according to the invention, also enables them to be used to detectthe noises and vibrations resulting from flows circulating inside the well.
Afurther important advantage ofthe process lies in the fact that the installation of seismic sensors is very easily adapted to the equipment methods used in petroleum wells, the cementation also being used to couple the seismic sensors to the environmental formations.
Other characteristics and advantages offered by the process shall be revealed from a reading of a description of a number of embodiments given by way of example by no means restrictive and relating to the annexed drawings in which:

Figure 13 diag ramatical Iy represents the disposition of a seismic sensor inside its receptacle.
Figure 1 shows a well 1 which is drilled to a first diameter upto a certain depth and, especially through the production zone, to a second diameter less than the first one. The well is conventionallyfitted out with a casing made up oftwo parts 2a and 2b with unequal sections adapted to the diameters of the drilling. The part with the smallest diameter 2b is fitted with a variable volume packer sealing device 4 which is expanded to wall-in the ring-shaped space between itself and the other section 2a having a lar ger diameter and close to one oftheir mutual extremities. Inside the casing and as far as its section 2b with the smaller diameter, a tubing 5 is disposed.
Another packer sealing device 6 is disposed nearto theinnerextremityofthetubing Ssoastowall-in,in an extended position, the ring-shaped space between it and the lower part 2b ofthe casing. A pumping u nit 7 supplied by a feeding electric 8 is disposed on the tubing 5. The part of the casing 2b crossing the production zone P is provided with a number of orifices 9. Atubing head 27 fitted with valves closes the casing at its upper extremity.
The process according to the invention consists of disposing one or more seismicsensors insidethe casing at its section having the largestdiameter2a (or its section having the most restricted diameter 2b if the volume ofthe outer ring-shaped space so allows) before it is descended into theweilbore.
These seismic sensors are connected to the surface by one or more transmission cables 11. The nextstep is to cement the casing. To achieve this, as is already known, a tube 24terminated by a special injection joining piece 25 and containing a reverse-lockvalve is descended into the casing 2 as far as possible to its lower extremity. The tube 24 is immobilized by a packer sealing device 26 and cement is injected. The cement gradually fills up by ascending the ringshaped space between the casing 2 and the hole 1. At the end ofthe cementing stage, all the seismic sensors 10 disposed inside the ring-shaped annular space are imbedded inside the cement.
Around the casing 2 and in orderto facilitate its descent, centering elements 12 of a known type are fixed (Figure 2), these having flexible blades or radial blades,forexample. According to anotherembodiment, the seismic sensors 10 are secured to centering elements 12. The connecting wire 11 (or wires if there are more than one) is kept against the outer wall ofthe casing 2 bythe clamping collars 13.
When the volume of the boxes housing the used seismic sensors 10 becomes incompatible with the dimensions ofthe ring-shaped space between the drilling and casing 2, dissymetrical guidance elements 14 (Figure 3) can be used to bring the casing 2 out-of-centre along that part of its length along which are disposed the sensors (Figure 4). The seismic sensors can be secured to the guidance elements 140r preferably, as shown by Figure 3, kept againstthe outerwall ofthe casing 2 bythefixing clamps 13 of the linkcable 1 for example. Its also possible to use casings comprising (Figure or 6) at least one section 15 whose diameter is restricted.
The restricted part may be symetrical (Figure 5) or even dissymetrical (Figure 6) if all the sensors are disposed on the same side of the casing.
According to another embodiment, a layer of elastic material 16 is inserted between each seismic sensor 10 and the wall of the casing 2 (Figure 7) so as to acoustically uncouplethe latter. The layer 16 may possibly be an outer coating of the casing.
All the seismic sensors 10 are disposed insidethe ring-shaped space around the casing 2 so as to be used, as shown by Figure 8, to record seismic readings. A seismic source 17 (a vibrator or pulse source) generates on the surface ofthe ground seismic waves which spread out in depth. The waves sent back by the various underground reflectors, and in particularthose of the production zone P, are received by the various sensors 10 and the seismic signals detected are transmitted bythetransmission cables 11 to a recording laboratory 18.
The seismic sensors can also be used to perform seismic prospection operations from well to well or even to produce a non-functional monitoring of phenomena occurring inside a producing well (flow noises offluids circulating inside the columns) or when production has stopped (detection of formation fracturings caused by the production or injection offluids). The seismic sensors used are, for example, geophones oraccelerometers.The number used and their disposition are selected according to the intended applications.
The sensors are disposed, for example, according to one and the same casing 1 generator, as shown by
Figure 8. It is also possible to use directional sensors (Figure 9, 10) whose axes are tangentially directed towards the casing (sensor 19) or along radial directions (sensor 20) or even along intermediate dir ections (sensor 21). These intermediate directions can be contained inside the transversal plane, as shown by Figure 9, or even inclined towards the top or bottom in relation to such plane. At a given location, it is possible to dispose a box 22 containing 3 directional sensors orientated along three orthogonal directions.
It is also possible to dispose the sensors so as to determine the incoming direction of seismic signals.
To this end, several directional sensors 23 are disposed on the periphery of the casing inside a given transversal plane at 1200 from each other. According to the mode of embodiment of Figure 10, the axes of the sensors are disposed radially. But this is not restrictive. It is also possible to incline the axes ofthe sensors in relation to the transversal plane, eithertowards the top of the shaft or towards the bottom, the angle of slope being any size whatsoever.
In its most usual configuration, the set of seismic sensors may include several sets of sensors divided up along part of the casing, each of the sets comprising a number of sensors, possibly directional, and disposed on the periphery of the casing.
Byway of example, one mode of embodiment allows several directional sensors to be connected to the casing and consists (Figure 12 and 13) of securing to the latter sleeves comprising one or more receptacles. Each sleeve has two female mouds 28,29 enclosing the casing and joined together by bolts (whose axes are marked 30). The sleeve is dissymetrical. Thethickestfemale mould (28) comprises three cylindrical receptacles 31,32,33 whose axes are oriented along three orthogonal directions, i.e. two inside a horizontal plane and the third being parallel to the axis ofthe casing 2. Each receptacle is closed by a sealed cover 34. Atwin conducting wire 35 is connected to each geophone 36. Conventional means (not shown) are connected to the cover 34 so as to ensure imperviousness of the wire passage 35.
Each sleeve with three receptacles could be replaced bythree sleeves having a shorter length, each comprising a receptacle, such as 31 or 32, whose axis is contained inside a transversal plane or a receptacle such as 33 whose axis is parallel to the casing 2.
Achange in orientation of a geophone inside atrans- versal plane is easily obtained by causing the sleeve 28toturn in relation to the casing.
