Definitions

  • the present invention relates to a device for processing and interpreting drilling data which is arranged at the bottom of a well and, more particularly, to such a device intended for use in an oil drilling.
  • the present invention also relates to a method allowing the implementation of this device.
  • the master driller When drilling a well, for example an oil well, it is desirable for the master driller to know the behavior of the lining and the tool at the bottom of the well in order to better control the parameters of the drilling. It is preferable to know these conditions in real time, which requires means of transmitting data from the bottom of the well to the surface.
  • the master driller will be able to react quickly to any event at the bottom of the well, for example, change of rock type, tool wear or mechanical instability.
  • the pressure waves propagate at around 1500 m / s; between bottom and surface, they undergo many reflections.
  • the data transmission rate does not exceed a few bits per second.
  • the document GB-A-2,216,661 describes a device for measuring the vibrations of a drill string, disposed at the bottom of the well, and which comprises a processor intended to record the data supplied by an accelerometer.
  • the device detects acceleration levels that exceed a predetermined value and only these levels are signaled to the surface. In this device, therefore, data, which are a function of a single parameter, are sent to the surface, only when a predetermined threshold is exceeded, and this without any analysis of physical behavior having been undertaken.
  • Document EP-A-0 468 891 describes a measuring assembly, placed on the surface at the upper end of a drill string, which is intended to transmit by radio to a remote processing center, These complete signals which are a function of measurements taken at the surface.
  • the subject of the present invention is a method for processing drilling data, at the bottom of a well, which makes it possible to develop, at the bottom, various diagnoses specific to the overall or individual behavior of the drilling tool, to the drill string, drilling mud, and / or the well itself, and to report these diagnoses to the surface by one of the usual data transmission means.
  • the method according to the invention makes it possible to optimize the processing of the data and to output indications which, once transmitted to the surface, make it possible to improve the conditions of drilling.
  • the present invention also relates to a device for processing drilling data implementing the method of the invention.
  • the invention provides a drilling data processing device intended to be mounted at the lower end of a drill string, arranged in a wellbore, and implementing the method according to the invention, the drill string being provided with a drilling tool, a measuring assembly and means for transmitting data from the bottom to the surface, characterized in that the device also comprises means allowing interpretation, then generation of diagnostics to be sent to the surface.
  • FIG. 1 shows a drilling assembly comprising a mast 10 provided, in a manner known per se, with a hook 12 to which is suspended a drill string, generally represented at 14.
  • the drill string 14 comprises a tool for drill 16, drill rods 18 and drill rods 20.
  • the drill string 14 is rotated by a rotation table 22 or by a motorized injection head.
  • a conduit 24 introduces pressurized drilling mud inside the rods 20. This mud exits with the tool and circulates in the space between the wall of the well and the drill string 14. It is recovered at the level of a conduit 26, recycled and then directed to storage tanks (not shown).
  • a device for processing and interpreting drilling data 28 is disposed inside the lining, as close as desired to the tool, between the drill rods 18 and the tool 16.
  • the device comprises a processing and interpretation circuit 30 and means for transmitting data to the surface.
  • the data transmission means may include an electric cable, a system of wired rods, an electromagnetic transmitter or, in the example illustrated, a system of transmission by pulses generated in the mud.
  • a servovalve mounted in a subassembly 30 disposed adjacent to the tool 16 is intended to selectively modulate the flow of the mud under pressure in order to create pressure waves in the mud.
  • Measuring and monitoring devices are arranged in the subassembly 30 making it possible, in a known manner, to generate pressure waves in the mud which are representative of the messages transmitted from the bottom. These pressure waves are detected on the surface by a pressure sensor 32, mounted on the conduit 24.
  • the drilling data processing and interpretation device 28 as well as the method allowing its implementation make it possible to process the various measurements taken at the bottom and to send various diagnoses to the surface, for example diagnoses of malfunction of the assembly drilling (precession, tool rebounds, torsional waves or jams) and the state of the tool (wear of the teeth and bearings of the thrones, wear of the cutting tools).
  • the treatment method according to the invention makes it possible to have a quantification of the various dynamic measurements allowing to have a scale in the severity of the vibrations, thus making it possible to assess the effectiveness of the actions undertaken on the surface by the master driller.
  • the processing and interpretation circuit 30 receives data taken by various measurement devices which are arranged in a measurement assembly 36 (see FIG. 1) located next to the tool 16 Data coming from various bridges of strain gauges 38, torsion 40, or flexion 42, from various magnetometers 46, from axial accelerometers 48, from radial 50 and from transverse 51 join through a anti-aliasing filter 52 a multiplexer 54.
  • the processing and interpretation circuit 30 is supplied by a sub-assembly 62 which includes an alternator 64 driven by the drilling mud at an input 66, an electrical regulation circuit 68 and accumulators 70.
  • a bus of command 74 controls, among other things, the transmission system 76 connected to a modulation servo valve 72.
  • a non-volatile memory 59 is intended to store information temporarily; this information is reserved for interpretation when the tool returns to the surface.
  • Other measuring devices can be used to determine the following parameters: weight on the tool, torque, internal and external pressures, internal and external temperatures and mud flow rate.
  • the processing circuit 30 makes it possible to signal to the surface various states, malfunctions or failures or severity of vibration of the drilling assembly.
  • FIG. 3 A method using the device of the present invention is shown diagrammatically in FIG. 3.
  • This preprocessing step makes it possible to verify that all of the measurements are correct and also makes it possible to calculate the speed of rotation of the tool from magnetometric measurements DMGX and DMGY.
  • the measurements being made in a movable coordinate system, they should be replaced in the fixed coordinate system.
  • the dysfunction algorithms 82 are shown in more detail in FIGS. 5 and 6. These algorithms make it possible to quantify the entropy of the different dynamic measurements (DWOB; DTOB; DBNX; DBNY).
  • the step of the method represented in FIG. 6 makes it possible to detect all the types of precession and to quantify them according to their meanings.
  • FIG. 7 is shown the last data processing step, that of the observers 84. This step makes it possible to determine the energy consumed by the tool per unit of rock destroyed. With these data, one can prepare an energy balance of the tool - which constitutes, for the driller, a good indicator of the functioning of the tool and its progress.
  • the pressure sensor 32 intended to detect the pulses generated in the mud, is connected to a frame decoder and to an interpretation station (not shown) which advantageously is produced by a desktop computer.
  • the processing circuit 30, instead of sending numerous data to the surface, which is a function of each of the measurements taken at the bottom, sends to the surface only signals which illustrate the operating state of the drill assembly. Obviously, the speed necessary for these transmissions remains compatible with the state of the art.
  • the processing and interpretation device is capable of defining priority in the sending of these messages.
  • the device for processing and interpreting drilling data of the invention can be used in combination with a device for dynamic measurements for a drill pipe as described in document EP -A-0431136, or in French patent applications 90 09638 or 90 12978.
