Description
Technical Field
The invention belongs to the technical field of ocean detection, and particularly relates to a deep sea heat flow measuring method and system based on real-time monitoring of an operation state.
Background
With the deep research on natural disasters such as marine resource development, deep sea science, earthquake and tsunami, countries in the world begin to advance into deep sea strategic deployment on the basis of deep shallow sea research, and how to maximize the improvement on the operation basic data acquisition efficiency under the effective cost control is the most urgent need for deep sea investigation. Seafloor heat flux measurement is an indispensable geophysical survey method for studying marine geology. In order to know the structure and the state of a geothermal field in an exploration area, the submarine heat flow detection technology is favorable for knowing the distribution of shallow deposits, petroleum and natural gas and the thermal state of deep crustal and even the whole ocean rock ring. In a hydrate research area, the burial depth of a seabed reflecting layer or a mineral layer is deduced by utilizing heat flow value data inversion, and the method can be used for reconstructing the ancient temperature change and the heat history transition history of the formation of the hydrate. The method has extremely important significance for researching dynamics and structural evolution of rock rings, and the obtained data can be used in the research fields of ocean shells, mantle velocity structures, plate diving zone characteristics, ocean basin evolution dynamics mechanisms and the like, and has wide application in the aspects of earthquake activity monitoring, earthquake and tsunami early warning research and the like.
The conventional heat flow acquisition is roughly divided into two types, one type is that borehole heat flow data is obtained through logging data of offshore oil drilling, the data are mainly concentrated in continental areas of continental shelves or deep sea basins, and the requirement for carrying out large-area investigation cannot be met due to the limitation of the number of deep sea boreholes; the other method is to insert a seabed heat flow probe (LISTER type and EWING type) into seabed surface sediment to obtain heat conductivity and temperature gradient parameters of the seabed, and then obtain heat flow data through calculation. Although the technology realizes heat flow measurement, the measurement is influenced by complex seabed sediment, water depth, ocean current and the like in the deep sea operation process, measurement equipment and an operation ship are easily influenced by factors such as wind power, ocean current and the like in the deep sea operation process, so that the problems of deviation of actual heat flow operation stations and the like are caused, the operation efficiency is relatively low, and the requirement of accurate research on the large-density heat flow seabed heat flow in the deep water cannot be met. In the deep sea heat flow research, especially in the regions with severe local heat flow change such as fault comparative development and the like, if the position information of the underwater heat flow station is not accurate, the heat flow measurement deviation can be huge. In addition, the deep sea bottom is far away from a source, the water content and the thickness of the sediment of the deep sea bottom are small, and the deep sea heat flow measurement is difficult to fill, so that the submarine filling process of the heat flow meter is lack of monitoring, and the measurement operation risk is greatly increased. In addition, the conventional measurement method is to lower the heat flow measurement equipment for each measurement, and to lift the measurement equipment to the operation deck after the single measurement is finished, so that the repeated operation is carried out, and the heat flow measurement operation efficiency is very low.

Preferably, the heat flow meter 9 is of the german fielax list series, and the heat flow meter 9 is internally integrated with a KUM MATUI inclinometer, an accelerometer, a temperature sensor and a pressure sensor, and can simultaneously measure the inclination angle, the acceleration, the temperature and the pressure. Of course, during the actual use process, the measurement device for the inclination angle, the acceleration and the pressure can also be realized in the form of mounting of an independent device. The ultrashort base array 4 and the ultrashort wave baseline transponder 6 adopt Sondyer Range 2, the heat flow data recording and implementing transmission module 8 adopts SDA data acquisition software, the multibeam measuring equipment 13 adopts German Elac L3 SB3012, the deep water shallow formation profiler 14 adopts KONGSBERG TOPAS PS18, and the acoustic Doppler current profiler 15 adopts TRDI/American OS-38.

According to the obtained seabed sediment information, the heat flow operation station is finely adjusted, and the filling depth of station operation is ensured because the deep sea topography of the upper covering plate sheet in the Maryland area is relatively complex and the soft deposition area is optimized.

In the operation process, the depth of the heat flow operation station position needs to be ensured to be smaller than the positioning action depth of the ultra-short baseline, and if sea surface storms are large, the marine dynamic positioning system needs to be started in the whole process to control the position of the operation ship.
Specifically, as shown in fig. 2, during the continuous lowering process, the length of the release data transmission bearing cable 5 and the position of the ultra-short baseline transponder 6 are observed, and in combination with multi-beam water depth information, the ultra-short baseline transponder 6 hovers at a height of 100 meters above the seabed 10, the release of the data transmission bearing cable 5 is suspended, the heat flow meter 9 is kept still for 5 minutes, after the heat flow meter 9 is stabilized, the winch 2 is lowered at full speed, and the release of the cable is stopped after the heat flow meter 9 touches the seabed 10.

Preferably, after the measurement of the work station is completed, the heat flow meter 9 is lifted based on the minimum water depth between the work station and the next work station, and when the lifting height exceeds 100 meters, the lifting is stopped. And then moving the operation ship to the next operation station at the speed of 1-2 sections, observing the relative position of the ultra-short baseline transponder 6 and the operation ship 1 after the ship reaches the operation station, continuously observing the inclination angle, the acceleration, the pressure and the temperature data of the heat flow meter 9, measuring the heat flow of the point after the data are stabilized, and repeating the heat flow acquisition process. And continuously positioning the ultra-short baseline equipment in the heat flow measurement process, and detecting the state of the equipment through real-time flow meter 9 inclination angle, acceleration, pressure and temperature data.
