Description
Technical Field
The invention relates to the technical field of dry hot rock exploitation, in particular to a dry hot rock directional injection and production device and a development method.
Background
In recent years, development and utilization of deep geothermal resources are rapidly developed, and the deep geothermal resources become important research strategies to replace clean energy sources in various countries in the world, and can be divided into two types, namely water heating type and dry heating rock type. The dry hot rock is high Wen Yanti which is buried in the underground with the depth of 3-10 km and does not contain water or steam, mainly comprises igneous rock such as granite, has the temperature higher than 180 ℃, has the characteristics of high temperature, hardness and compactness, and can contain heat energy which is an object for development and utilization. The dry hot rock resources have huge development potential, wide distribution range, cleanness and sustainability, and the energy contained in the deep dry hot rock of the crust is estimated to be 30 times of the total energy of global fossil energy. The dry and hot rock resources are obviously different from the traditional geothermal heat in temperature, lithology, compactness and the like, and the exploitation and utilization modes are also greatly different.
Under the current technical conditions, the dry-hot rock resource development technology is still immature, the exploitation cost is high, and main technical bottlenecks are that efficient and stable communication between wells is difficult to realize, so that the area of rock mass participating in heat exchange is small, the temperature of a reservoir is reduced rapidly, and the heat extracted to the ground is insufficient. At present, domestic dry rock is not commercially operated and developed, and only French Su Erci dry rock projects are explored and put into commercial operation for over 20 years abroad.
In recent years, the state is increasingly pressing on clean energy demands, and the key technology of dry hot rock resource exploitation is increasingly put into practice. Patent CN106885385A discloses a single-well dry hot rock heat energy extraction system, CN113513299a discloses a dry hot rock vertical well same-well injection and extraction method, patent CN112303945B discloses a dry hot rock non-fracturing butt joint well heat extraction device, patent CN110006185B discloses a dry hot rock geothermal extraction method, patent CN108224820a discloses a dry hot rock stratum well pattern structure, CN110360761a discloses a tree-shaped dry hot rock well structure and extraction method, and the above-mentioned patents realize the extraction of dry hot rock heat energy to different degrees.
However, the above patent fails to effectively solve the problems of small heat exchange area (single well) and large input-output ratio of the dry-heated rock, in addition, the dry-heated rock has extremely high drilling cost (more than 50% of development cost), simply increasing the number of wellbores and increasing the heat exchange area of the well pattern density does not have economic feasibility, the directional injection and production equipment is needed to be utilized in the process of exploiting the dry-heated rock, the traditional injection and production equipment consists of structures such as a derrick, a drilling machine, a drill rod and a hoisting machine, the drill rod is drilled into the well when the drilling machine is used, after the drill rod is completely drilled into the well, the hoisting machine is used for hoisting another drill rod to be fixed on the drilling machine, and the drilling operation is continued.
Although the existing drilling machine has many advantages, certain limitations still exist in the practical use process, as the hoisting equipment needs to align the joint of the drill rod and the drilling machine when hoisting the drill rod, the installation positions of the hoisting equipment and the drilling machine are relatively close, so that the hoisting equipment cannot realize hoisting in the drilling process, and the hoisting can be carried out after the drill rod is completely drilled and the drilling machine is completely reset, the mode is relatively time-consuming, and the drilling efficiency is greatly reduced.
