Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations (or steps) can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
At present, no mature online monitoring scheme exists in the deep water testing field, and no mature scheme exists for monitoring the temperature and the pressure of a deep-sea hydrate monitoring well. However, in order to solve the technical problem of deep water testing, the following two schemes are generally adopted for construction in China:
firstly, a storage type ground reading scheme: installing a storage type sensor underground, recording data in a test process, and taking out the sensor after the test is finished and reading the data for analysis; according to the scheme, the judgment is carried out afterwards, and the test data cannot be acquired before the sensor is taken out, so that the effectiveness of the test or the monitoring cannot be evaluated in real time.
II, storage type cable reading scheme: the underground storage type sensor with the short transmission function is installed underground, the parameters of the underground tool need to be adjusted or the reading device is placed through a cable after the test is finished, and data are transmitted to the ground through the cable to be analyzed and judged whether the well testing process is successful or not. Fig. 1 is a schematic construction diagram of a storage type cable reading scheme provided by an embodiment of the present invention, and referring to fig. 1, data of a downhole testing tool is collected and stored in a storage unit of the downhole testing tool through downhole telemetry, a surface acquisition system is lowered to a downhole coupler part through a cable dragging data reading short circuit, and testing data stored in the downhole telemetry unit is acquired through a wireless communication mode. Although the scheme can acquire underground data in the test process, the cable construction difficulty in the deep sea field is higher, and the long-time offshore cable construction cost is higher, so that the scheme is not well applied to an offshore platform.
In addition, in some key wells, some foreign companies' testing teams can provide technical services for the key wells by using acoustic wireless remote measuring equipment and downhole tools; FIG. 2 is a schematic diagram of a construction in which the acoustic wireless telemetry is wirelessly read, and the operation cost of a whole set of downhole tools per well is 300 ten thousand dollars per well, and the cost of rented equipment is high.
Fig. 3A is a flowchart of a sound wave wireless transmission method provided in an embodiment of the present invention, where this embodiment is applicable to a case where data is transmitted by using sound waves, and the method of this embodiment may be performed by a sound wave wireless transmission device, where the device may be implemented by using hardware and/or software. The device can be configured in a server for sound wave wireless transmission. The method specifically comprises the following steps:
s110, obtaining data to be coded in the monitoring well, and coding the data to be coded to generate a first electric signal.
The monitoring well can be used for evaluating the exploitation effect of the natural gas hydrate, the monitoring well needs to be drilled near the exploitation well, parameters such as temperature and pressure in the exploitation process are monitored on line, and therefore the monitoring parameters capable of evaluating the exploitation process are obtained. Deep sea hydrates may refer to natural gas hydrates with buried water depths of more than 1500 m.
Hydrate decomposition in the deep water natural gas hydrate pilot production process can cause changes of the temperature and the pressure of the formation environment, so that how to obtain the temperature and the pressure of a natural gas hydrate reservoir layer and the wellbore pressure on line in real time is a technical problem. The trial production of the deep-water natural gas hydrate deploys monitoring wells around the production well, fig. 3B is a schematic diagram of the trial production monitoring deployment of the deep-water hydrate provided in the embodiment of the present invention, referring to fig. 3B, the production well is used for trial production and production of the natural gas hydrate, and the monitoring wells are used for monitoring changes in formation temperature and pressure caused by the production and decomposition of the hydrate; in the construction process, the monitoring well is not connected to the offshore drilling and production platform in many times, which brings great difficulty for the online real-time monitoring of the monitoring well. In addition, the monitoring well is only provided with a casing pipe and is not provided with a drilled oil pipe, so that the traditional acoustic communication instrument based on oil pipe or drill pipe transmission is not suitable for use.
Wherein the data to be encoded includes, but is not limited to, monitoring temperature and pressure within the well. Presetting a sensor in the monitoring well, and acquiring data to be coded in the monitoring well in real time by adopting the sensor; and receiving the data to be coded by adopting sound wave wireless transmitting equipment, and coding the data to be coded to generate a first electric signal for transmission.
And S120, converting the first electric signal into a sound wave signal by adopting a sound wave transducer, and transmitting the sound wave signal along the inner wall of the sleeve.
The acoustic wave transducer can convert an electric signal into an acoustic wave signal and transmit the acoustic wave signal along the inner wall of the casing. Fig. 3C is a schematic diagram of data to be encoded according to an embodiment of the present invention, and referring to fig. 3C, an electric signal output by an acoustic wireless transmitting device is converted into an acoustic signal by an acoustic transducer, and the acoustic signal is transmitted to an acoustic wave detector along an inner wall of a casing for processing.
In order to obtain real-time temperature and pressure in the monitored well, various wireless transmission means have been tried. For example, an electromagnetic wave measurement while drilling system (ZTS system) uses electromagnetic waves for wireless transmission to obtain formation parameters in real time, but is greatly affected by formation resistivity, and is not suitable for the deep sea field; the vertical drilling system adopts drilling fluid pulses to carry out wireless transmission to obtain stratum parameters, but the vertical drilling system is only applied to the engineering environment with drilling fluid media or while drilling and is not suitable for the deep sea field; therefore, the wireless transmission means applied to the field of deep sea monitoring in the embodiment of the invention is sound wave wireless transmission. Table 1 is a comparison table of wireless output techniques provided in the embodiments of the present invention, and referring to table 1, the transmission of sound waves is not affected by drilling fluid and formation resistivity. Therefore, the embodiment of the invention adopts the acoustic wave signal to transmit the acquired temperature and pressure data in the monitoring well.
TABLE 1 radio output technique contrast table
| Transmission medium | Speed of transmissionRate/bps | Reliability of | Application conditions |
| Electromagnetic wave | 1-12bps | In general | Influenced by formation resistivity |
| Drilling fluid pulse | 0.5-5bps | Is preferably used | Require a drilling fluid medium |
| Acoustic waves | 30-100bps | Is better | Is not influenced by drilling fluid and formation resistivity |
S130, the sound wave detector receives the sound wave signal and converts the sound wave signal into a second electric signal.
Optionally, the receiving the sound wave signal and converting the sound wave signal into a second electrical signal by the sound wave detector includes:
receiving a sound wave signal transmitted along the inner wall of the sleeve, preprocessing the sound wave signal and converting the sound wave signal into a second electric signal;
wherein the preprocessing comprises filtering unwanted acoustic signals and amplifying low-amplitude acoustic signals by filtering amplification and program-controlled gain.
The acoustic wave detector may be a device that processes the acoustic wave signal to detect a useful signal in the acoustic wave signal. For example, the sound wave detector receives the sound wave signal, filters and amplifies the sound wave signal and filters useless signals in the useless sound wave signal through the programmable gain, achieves gain control or range conversion of output signals, indirectly improves the resolution of input signals, and amplifies the sound wave signal with small amplitude. Referring to fig. 3C, the acoustic wave detector converts the acoustic wave signal into a second electrical signal and transmits the second electrical signal to the acoustic wave wireless receiving device.
It is to be understood that the first electrical signal may be a reference, and is any electrical signal selected from the electrical signals in order to distinguish different electrical signals that appear before and after the embodiment and perform corresponding logic, so as to explain the logic performed from the selected electrical signal, and therefore, the electrical signal that appears first in this document is referred to as a first electrical signal, and other electrical signals that appear later and are different from the first electrical signal are referred to as second electrical signals, which will not be described in detail later.
S140, decoding the second electric signal to obtain decoded data, and sending the decoded data to wellhead receiving equipment.
The decoded data may be decoded data obtained by decoding the acquired second electrical signal; for example, the second electrical signal acquired by the acoustic wave wireless receiving device is sent to a Micro Controller Unit (MCU) for related processing, demodulation, and decoding, the temperature and the pressure acquired by the sensor are recovered, and the decoded data is sent to the wellhead receiving device.
The embodiment of the invention provides an acoustic wave wireless transmission method, which comprises the steps of obtaining data to be coded in a monitoring well, and coding the data to be coded to generate a first electric signal; wherein the data to be encoded comprises temperature and pressure within the monitoring well; converting the first electric signal into a sound wave signal by adopting a sound wave transducer, and transmitting the sound wave signal along the inner wall of the sleeve; the sound wave detector receives the sound wave signal and converts the sound wave signal into a second electric signal; and decoding the second electric signal to obtain decoded data, and sending the decoded data to wellhead receiving equipment. By adopting the technical scheme of the embodiment of the invention, the temperature and pressure data in the monitoring well, which are obtained by the preset sensor, are transmitted by sound waves, so that the online monitoring can be realized, and the data in the monitoring well can be obtained in real time; the data transmission is carried out by adopting the sound wave signals, so that the attenuation of the data is effectively reduced, and the integrity of the data can be effectively ensured; and cable construction is not adopted in the construction process, so that the offshore operation risk is reduced.
Existing data transmission schemes applied in the field of oil and gas wells include, but are not limited to, data transmission using cables, data transmission using electromagnetic waves, data transmission using drilling fluid pulses, and data transmission using acoustic waves. The application defects of various technical schemes in the wireless transmission of the parameters of the deep-sea hydrate monitoring well are as follows:
the parameter monitoring of the deep sea hydrate monitoring well is a long-term dynamic process, the cost of offshore operation by using a cable is high originally, if the cable operation is adopted in the monitoring well, equipment needs to be lifted underground for a long time, and well head equipment can easily cut the cable along with the fluctuation of seawater, so that great construction risk is brought; once the cable construction is carried out, an expensive offshore platform needs to be rented for operation, and the daily renting cost of the offshore platform is very expensive;
electromagnetic waves are greatly attenuated underground and offshore, and data wireless transmission can be performed in certain specific areas (stratum resistivity is moderate) on land by adopting the electromagnetic waves, but the application scene is limited seriously, the stratum resistivity is too low, the electromagnetic waves are absorbed by the stratum and are difficult to transmit through the stratum, the propagation distance of the electromagnetic waves can be influenced when the stratum resistivity is too high, and the electromagnetic wave communication through the stratum mostly adopts low-frequency-band electromagnetic waves, and the transmitting antenna is difficult to realize underground. In addition, in deep sea hydrate monitoring, the resistivity of the undersea bed is low and is not suitable for electromagnetic wave communication; it is also difficult to deploy electromagnetic wave receiving antennas on undersea foundations in deep sea areas with water depths exceeding 1500 m;
in a monitoring well, no drilling fluid pulse exists, and data transmission of the drilling fluid pulse cannot be adopted;
in the existing construction scheme, the storage type cable reading scheme depends on a cable to carry out data transmission, and the defects of the storage type cable reading scheme are the same as those of cable operation and are not repeated;
in conclusion, in the deep sea hydrate monitoring well, data transmission by sound waves is the most effective technical means. Therefore, the embodiment of the invention provides a sound wave wireless transmission method.
