Definitions
- the present invention relates to a method and a device for evaluating the factor for the formation of underground zones from rock cuttings brought to the surface during well drilling operations through underground deposits.
- FF Training Factor
- the conductive liquid preferably using brine or another equivalent conductive liquid.
- the invention relates to a method for evaluating in a simple and rapid manner, while overcoming the problems associated with the previous techniques, the factor of formation of an underground zone from drill cuttings raised to the surface of the well drilling, in which a device is used comprising a cell (1) adapted to contain drill cuttings and provided with electrodes connected to a device for measuring the conductivity of the contents of the cell.
- the method includes at least the following steps:
- the cell is filled with a first electrolytic solution (A) of known conductivity ( ⁇ ⁇ ) so as to saturate the cuttings with this first electrolytic solution
- the overall electrical conductivity ( ⁇ A ° ) of the cell with its contents is measured; the first electrolytic solution (A) remaining between the cuttings is removed from the cell;
- the cell is filled with a second electrolytic solution (B) of known conductivity ( ⁇ ⁇ );
- the formation factor (FF) of the cuttings is deduced from the previous measurements.
- the cuttings can be saturated with carbon dioxide by injecting this gas into the cell, before filling the cell with the first electrolytic solution (A).
- the electrolytic solutions can be brines of different concentrations, the concentration and conductivity of the first electrolytic solution (A) being able to be higher than those of the second solution (B).
- the first electrolytic solution (A) remaining between the cuttings can be removed from the cell by gravity emptying.
- the first electrolytic solution (A) can also be removed by an injection of air.
- the pressure of the injected air can be determined according to the size of the pores of the cuttings.
- the capillary desorption can be carried out using a semi-permeable membrane allowing the first electrolytic solution to pass but not allowing the air to pass.
- the training factor can be determined from the theory of mean fields.
- the invention also relates to a device for implementing the method described above.
- This device includes: - means for saturating the cuttings contained in the cell with CO2;
- said means for emptying the device can comprise a semi-permeable membrane, permeable to brine and impermeable to air.
- Figure 1 schematically shows a conductivity measuring device with four electrodes
- FIG. 2 illustrates the state A obtained initially by filling with a first liquid A, the cell containing the cuttings
- FIG. 3 illustrates the state B obtained in a second step after exchanging the liquid A with another liquid B
- FIG. 4 illustrates experimental data showing a drift of the conductivity signal at long times after a draining operation
- FIG. 5A shows, in the form of a crossed diagram, the results obtained with the self-similar approach
- FIG. 5B shows, in the form of a crossed diagram, the results obtained with the derivative approach.
- FIG. 6 shows a comparative table of the results obtained with the two methods envisaged (self-similar and derivative) from the cuttings and with the reference measurements obtained from experiments on carrot.
- the method, according to the invention, for rapid evaluation of FF from drill cuttings is based on the acquisition of experimental data obtained by measuring the conductivity of drill cuttings under different conditions.
- the conductivity depends on the conductivity of the rock fragments but also on the liquid located between the fragments.
- the proposed method makes it possible to interpret the experimental measurements in term of FF using theoretical models. Two application cases are proposed. They show the very good agreement between the values of FF obtained from carrots and the values of FF obtained from fragments of these carrots over a wide range of FF.
- the invention provides a method and a device for quickly and rigorously calculating the formation factor, by using, among other things, conductivity measurements made with two conductive liquids which may be miscible.
- the two miscible and conductive liquids used are brines of different concentrations:
- the device pe ⁇ nettant the acquisition of measurements as part of the implementation of the invention, is shown schematically in Figure 1. It mainly consists of a containment cell (1) 3 cm long and a circular surface of 9.48 cm which gives a total volume of approximately 30 cm 3 . This corresponds to approximately 15 cm 3 of rock a once the cell is filled.
- This cell is made of a non-conductive material. It is closed at its opposite ends by two end pieces 2, 3 made of a conductive material.
- a variable frequency generator 4 is connected between the two nozzles 2, 3, and the current which it applies is measured by an ammeter 5.
- electrodes 6, 7 connected to a voltmeter 8.
- a pump (9) allows liquids to be introduced into the cell.
- the cell (1) is filled with the cuttings (or “cuttings"), previously cleaned and dried, and carbon dioxide until the cuttings are saturated with carbon dioxide.
- the volume of gas injected is such that all the pores of the cuttings are filled with carbon dioxide.
- the purpose of this operation is to improve the saturation of the cuttings by the brine thanks to the mechanisms of diffusion of CO 2 in the air and of the dissolution of the C02 in the brine, and not by air vacuum, which is more difficult. to implement.
- a conductive liquid A (a brine of concentration and therefore of known conductivity), until the cuttings are completely saturated by dissolution of the CO 2 in the brine, and the conductivity is measured.
- O A * This state, denoted state A, is represented in FIG. 2, where IA represents the liquid A in the inter-cuttings space and DA represents the liquid A in the cuttings.
- the liquid A is discharged by gravity drainage and under air pressure (or under brine depression).
- the pressure to be exerted depends on the maximum size of the pores of the cuttings. Too much pressure could desaturate, even partially, the spoil. This pressure must therefore be neither too high (partial desaturation of the cuttings) nor too low to limit the presence of liquid A in inter-cuttings. It is easily calculated from Laplace formulas.
- a pressure of 10 mbar (which can be controlled by a height of water imposed in a capillary of 10 cm) then makes it possible to ensure good drainage of the inter-cuttings space without desaturating the rock and this for a wide range of permeability (the air must not be able to enter the largest existing pore of the porous medium, the size of which corresponds to what is called the inlet pressure).
- the cell is filled with another conductive liquid B (brine less concentrated than brine A) without changing the nature of the liquid (brine A) saturating the cuttings.
- the volume fraction of medium 1 is denoted x and the volume fraction of medium 2 is denoted y, equal to 1-x.
- the medium 1 represents the inter-cuttings liquid A or B and the medium 2, the saturated rock cuttings.
- the conductivities of each of the media, inter-cuttings liquid and saturated rock cuttings, are noted ⁇ i and ⁇ 2 and the overall conductivity of the system is noted ⁇ .
- h and / are functions of the volume fractions taking into account the shape of the grains constituting the cuttings.
- Equations (2) and (3) can also be written
