Definitions
- the present invention relates to a device and a method for carrying out measurements on drilling debris or “cuttings”, in particular for continuously measuring by the principle of weighing, the flow rate of debris raised from the bottom of a well drilled by by means of a tool driven in rotation and using a cleaning fluid.
- the object of the present invention relates to a system capable of informing us, on the surface, of the instantaneous mass and / or volume flow rate of rocks drilled by a drilling tool.
- Document US-4 13511 is known which describes a continuous measurement system for the volume of drill cuttings and the quantity of drilling fluid entrained with these same cuttings. This system does not have the same objective as the present invention and is structurally different, in particular by the measurement means which use tanks filled with a fluid whose level variation is continuously measured.
- the present invention relates to a device for measuring the flow of cuttings from a borehole brought to the surface via a drilling fluid.
- the device comprises means for collecting the cuttings and means for continuously measuring the weight of the cuttings collected.
- the means for collecting the cuttings comprise a receptacle in the form of a bucket pivoting on an axis and means for tilting the receptacle so as to empty said bucket, and the measuring means comprise a measuring cell linked to said means of tilting to measure a stress substantially proportional to the weight of the excavated material collected.
- the tilting means may comprise a rotary shaft on two bearings, a pneumatic cylinder connected to said shaft, and a connecting piece of said cylinder with a fixed frame.
- Said measuring cell can be arranged on said connecting piece.
- the invention also relates to a method for measuring the flow of drill cuttings brought to the surface by means of a drilling fluid in which the following steps are carried out: a) the cuttings are collected continuously for a determined period in a receptacle, b) continuously weighing said cuttings accumulated during said period, c) emptying said receptacle at the end of said period, d) the operations a) and b) are repeated, e) the weights of the cuttings are accumulated by measurement processing means, f) a calculation of the cuttings flow is carried out, g) the measurement of the cuttings flow measurement is processed to calculate and / or record at least one of the following parameters: the cuttings flow as a function of time, the ratio of the cuttings flow to the forward speed, the ratio of the measured cuttings flow to the theoretical flow of drilled cuttings, the difference between the measured flow of cuttings and the theoretical flow of cuttings drilled.
- the density of the cuttings collected can be measured.
- the density of dry cuttings can be measured, that is to say after elimination of the drilling fluid.
- the parameters can be expressed in volume flow using at least one of the density measurements: before or after elimination of the drilling fluid.
- this device In order to use the cut flow measurement, we developed this device from the research of two main applications: a) Being able to view: "a provisional image of the profile of the well,
- Figure 2B shows a side view of the device.
- Figure 3 shows an example of the cut weight recording curve.
- Figure 4 shows an example of continuous recording of the cuttings flow in correlation with a drilling operation.
- the drilling principle comprises a pumping installation 6 which delivers a so-called “drilling” fluid into the interior space 8 of the lining by means of a pump, a pipe 9 and the injection head 5 .
- the drilling fluid descends towards the bottom of the well to spout out of the lining at the level of the drilling tool equipped with jets intended to clean rock debris, both from the cutting edges and from the working face.
- the fabrics are agitated with a vibratory movement to effect a mechanical separation between the debris and the drilling fluid.
- the fluid falls into a tank 13 to be recycled directly or after another separation treatment of the finer particles.
- the debris slide on the canvas to fall into the device 14 according to the invention where the mass flow is measured. Then, the weighed debris is discharged by means of the present device into a discharge pit 15.
- arms 17 connect the bucket to a shaft 18 fixed by at least two bearings 19.
- the bucket is thus linked in rotation with the shaft 18.
- the rotation of said shaft 18 causes the bucket between at least one cuttings receiving position and a cuttings emptying position.
- the presence of the two bearings 19 and the shaft 18 rigidly fixed to the bucket 16 makes it possible to obtain a very high rigidity of the assembly and thus to resist the shocks, vibrations and overloads commonly encountered in the area surrounding the vibrating screens.
- the end 26 of the body of the jack 21 cooperates with a part 25 which has the dual function of holding the jack so that it can actuate the bucket and transmit the force due to the weight of the load contained in the bucket to a cell 24 for measuring said stress, for example of the stress gauge type.
- a high and low stop 50 makes it possible to avoid an overload being applied to the cell 24 by limiting the movement of the free end of this cell. These stops are adjustable so that in normal operation they do not come into contact with the free end of the cell 24 but the contact is made before the cell is damaged by an overload.
- FIG. 3 represents an example of recording the weights P of cuttings (abscissa) as a function of time t (ordinates).
- the weight curve 31 decreases rapidly following emptying.
- the parasitic peaks that we observe are due to the dynamics of the displacements.
- the time interval V corresponds to the emptying time.
- the bucket has returned to the horizontal position and the weight of the cuttings collected increases.
- Curve 34 accumulates the weight being measured with the cumulative weight value at the time of the emptying phase. It can thus be seen in FIG. 3 that the measurement 31 cannot be used during the time interval V. However, the variations of this measurement can be estimated during this interval by exploiting the variations of the signal 31 before the signal of 11
- the conversion also requires knowing the density of the drilling fluid and that of the cleaned and dried cuttings. Proven methods exist to measure these two densities.
- the drilling fluid mention may be made of the mud balance or the gamma or coriolis hydrometer.
- cleaned and dried spoil one can use for example the method of weighing a determined volume of spoil and measuring this volume by measuring the increase in volume of a suitable fluid after having plunged the spoil.
- Parameter 1 of cuttings flow rate in volume unit / time unit makes it possible to analyze whether certain drilling actions are sufficiently effective for cleaning the well.
- Parameter 4 of cumulation of the cuttings flow in volume-volume unit drilled makes it possible to quantify the evolution of the degree of fouling of the well, that is to say the level of congestion of the well by cuttings, which gives an assessment of the level of risk of the packing becoming trapped in the well.
