Description

METHOD AND DEVICE FOR DETERMINATION OF FLUID INFLOW TO A WELL
This invention relates to a method for determining the inflow of fluid to a well. More particularly, it relates to a method for determining in which well portion of a petroleum well a particular fluid, or a particular amount of fluid, is entering the well. The invention also includes a device for practising the method, the device being well suited, in one embodiment, for shutting off an intermediate portion of the well .
During the production of petroleum, especially in the late phase of a well, considerable amounts of water may enter the well. It is often connected with difficulties to establish in which portion or portions of the well the water is entering.
According to the prior art, different measuring methods may be used, whereby it can be determined relatively accurately where in the well the inflow is occurring and at what rate. However, equipment of this kind is relatively complicated and expensive. The necessary time consumption for rigging equipment, measuring and rigging down, during which the well is unproductive, can be considerable.
The invention has for its object to remedy or reduce at least one of the drawbacks of the prior art .
The object is achieved according to the invention through the features which are specified in the description below and in the claims that follow.
A method is provided for determining at which portion of a petroleum well a particular fluid, or a particular amount of fluid, is entering the well, characterized by the method comprising the operations of:
- connecting an expandable plug to an actuator;
- moving the actuator and plug to a first position in the well ; - setting the plug in the well by activating the actuator;
- producing fluid from at least one portion of the well;
- determining the identity of at least one of the fluids; and
- releasing the plug by deactivating the actuator.
In addition, the composition of the fluids or the amount of the fluid produced can be determined.
If necessary, the actuator and plug are moved to a second position within a second well portion to be examined, after which the plug is set in the well by activating the actuator, and fluid is produced from the part of the well which is open. At least the identity of one of the fluids, the composition of the fluids or the amount of the fluid produced is determined, the plug being released by deactivation of the actuator.
With advantage, the actuator and plug are pulled up to the surface after the examination has been finished.
In this connection an actuator is an axial actuator, in which an actuator rod is moved relative to the actuator housing of the actuator. In the petroleum activity an axial actuator is often called a "stroker" . The stroker may be connected to a downhole tractor and/or to a cable or to coiled tubing which is connected to the surface. Most often, a stroker is pro- vided with an anchor to be able to attach to the borehole wall before the stroker is to be activated. It is normal to be able to control the actuator from the surface by means of electric signals or by means of so-called "mud pulse teleme- try" .
A plug is provided for practising the method, comprising an elastic element, a mounting holder and a holding-up element, movement of the mounting holder and the holding-up element in a direction towards each other causing the intermediate elas- tic element to be expanded radially, the mounting holder and the holding-up element being connected to the housing, respectively actuator rod, of an actuator.
The holding-up element is connected to the housing of the actuator by means of a first intermediate piece.
The mounting holder is connected to the actuator rod of the actuator by means of a mounting element. The mounting element extends through an opening in the elastic element.
The mounting holder is connected to the mounting element by means of a breakable securing element .
In another embodiment the plug includes two or more elastic elements. Two elastic elements are held spaced apart by means of a second intermediate piece.
An aspect of the plug is that the mounting element can be flowed through, for example by means of an internal bore, the mounting element being perforated.
Another aspect of the plug is that the holding-up element or the first intermediate piece can be flowed through, for example by means of a perforation.
Yet another aspect of the plug is that the intermediate piece can be flowed through for example by means of a perforation.
Thus the plug can be flowed through. By providing the plug with a lid near the mounting holder, when the second intermediate piece is also perforated, the plug will let fluid through only from the well portion which is between the elastic elements.
The plug may include more than two elastic elements so as to choose which ones of the portions of the well will be shut off and which ones will be able to produce fluid.
The proposed method and device provide a simple and cost- effective solution to a long-felt problem. After one well portion has been examined, the plug may be moved to a position within a second well portion for a new sample to be taken, and so on until the well has been mapped. Then, when it has been decided where in the well the fluid in question is entering, necessary measures can be taken in the relevant portion or portions in the well.
In what follows is described an example of a preferred method and embodiment which are visualized in the accompanying draw- ings, in which:
Figure 1 shows a well in which a plug has been positioned;
Figure 2 shows in section, on a larger scale, the plug mounted on an actuator;
Figure 3 shows the same as figure 2, but after the actuator has been activated;
Figure 4 shows the well in which a plug of another embodiment has been placed; and Figure 5 shows principally the same as figure 4 but after the actuator has been activated.
In the drawings the reference numeral 1 indicates a plug which is connected to an actuator 2, the actuator 2 being connected to a downhole tractor 4.
The plug 1 is in a first position 6 spaced from a second position 8 in a well 10.
The plug 1 includes a relatively elongated cylindrical, elastic element 12 which is provided with a centric through open- ing 14, see figure 2.
The elastic element 12 is formed with a cylindrical through opening 14 and is provided, at each of its end portions, with an outward-projecting, externally threaded pipe stub 16. Nearest to the actuator 2 the elastic element 12 is connected by means of the corresponding pipe stub 16 to a holding-up element 18. The holding-up element 18 is connected to the actuator housing 20 of the actuator 2 by means of a cylinder- shaped first intermediate piece 22.
At its opposite end portion the elastic element 12 is con- nected by means of the corresponding pipe stub 16 to a mounting holder 24. A breakable securing element 26 in the form of a brass bolt connects the mounting holder 24 to a mounting element 28 extending through the opening 14 of the elastic element 12.
The mounting element 28 is connected to the actuator rod 30 of the actuator 2.
After the plug 1 has been positioned in the well 10, the actuator 2 is activated, whereby the actuator rod 30 is moved in the direction of the actuator 2. The mounting holder 24 is moved by means of the mounting element 28 and securing element 26 towards the holding-up element 18 which is held at rest relative to the actuator 2 by means of the first intermediate piece 22, see figure 3. The elastic element 12 of the plug 1 is thereby brought to expand radially outwards, whereby the well 10 is sealed.
The plug 1 is released by deactivating the actuator 2 in such a manner that the mounting holder 24 takes its initial position relative to the holding-up element 18.
If the actuator 2 should fail after it has been activated, the plug 1 may be released by breaking the securing element 26, for example by means of a stroke.
When the plug 1 is set in a second position 8 further into the well 10 than the first position 6, fluid may be produced from those of the well's 10 portions that are upstream of the plug 1 in the well 10.
If desirable, the procedure may be repeated between more of the well portions 6, 8 and also the well portions not shown.
In another embodiment, see figures 4 and 5, the plug 1 is provided with two elastic elements 12. The two elastic elements 12 are kept spaced apart axially by a second intermediate piece 32.
In this alternative embodiment the mounting element 28 is tubular and perforated by means of openings 34. The holding-up element 18 is also perforated by means of openings 36.
When the plug 1 is set, the portion of the well 10 located between the two elastic elements 12 is sealed off from the other portions of the well 10, fluid from the portions of the well 10 located within the plug 1 being able to flow past the plug 1 via the tubular mounting element 28 and openings 34, 36.
As the plug 1 is shown in figure 5, the mounting element 28 is sealed by means of a lid 40 near the mounting holder 24. The lid 38 may be formed by a valve not shown.
By the second intermediate piece 32 being perforated by means of openings 38, fluid from the portion of the well 10 located between the elastic elements 12 may flow up in the well via the openings 34, 36, 38 and the mounting element 28, while, at the same time, the mounting element 28 is closed to inflow from other well portions. The openings 38 may be closable, for example by means of a movable slide not shown.
