Shale gas development in China is advancing slowly as a whole

wallpapers Industry 2020-12-09
Due to such factors as inadequate top-level design, imperfect policy system, key technologies controlled by people, and lagging construction of gas transmission pipeline network, China's shale gas exploration and development has made a "point breakthrough" in Fuling shale gas field, but on the whole, the progress is still very slow. Industry insiders and experts call on shale gas, as a new mineral, as the breakthrough point of China's energy management system reform with reform thinking, strengthen the top-level design, stimulate the enthusiasm of various market entities and local governments to participate in exploration and development, strengthen the construction of regulatory system, strengthen technical research, and improve the pipeline network system, so as to achieve a breakthrough in all aspects.

to strengthen the top-level design of new minerals needs to reform new thinking

Industry insiders interviewed by

generally believe that in shale gas exploration and development, there are mainly two aspects of interest relations that need to be straightened out by the state to strengthen the top-level design. One is the interest distribution relationship between the development enterprise and the resource location; the other is the interest coordination relationship between the main development status of central enterprises and market participation. In terms of

and

enterprise land relations, people in the land and resources industry said that shale gas, as an independent mineral, currently adopts a class of mineral resource management, and the allocation of mineral rights is in the Ministry of land and resources, and local governments can not intervene. Although we have carried out two rounds of innovation of shale gas mineral rights bidding transfer, the mode of unified management and allocation by the state has not been changed. The grassroots of

and

believe that this mode may bring many problems to local governments. For example, when transferring mineral rights, we often consider the value of compensation fees for single mineral resources, but we don't consider what kind of geological and environmental consequences will be left by resource development, investment in governance and restoration, and compensation for damage to ecological environment. Moreover, the maximum utilization of resources and the layout of pipelines are not taken into account, which is easy to cause resources The local government has paid the price of ecological environment and people's resettlement, but the "real gold and silver" obtained by the local government is very small. In the past, this problem existed in the development of oil and natural gas. Experts of

and

believe that Fuling shale gas field is a model of mutually beneficial and win-win joint development between central enterprises and local governments, but there is no relevant policy design on the top-level design of the country to give preference to local interests. Experts called for the establishment of interest compensation mechanism between shale gas development subject and resource location, so that local governments can share the dividend of resource development.

and

in the shale gas development of the relationship between the central enterprises and other market players, there are "money can not go in, gas can not come out". Zhang Dawei, director of the mineral resources and Reserves Assessment Center of the Ministry of land and resources, believes that one of the major problems restricting domestic shale gas development is that the mineral rights market has not been really liberalized. Although two rounds of bidding have been conducted, the problem of optimizing high-quality blocks has not been solved. PetroChina and Sinopec have many core and high-quality shale gas blocks, but due to limited energy, "two barrels of oil" has only carried out work on a few points. Other enterprises can only choose the second and third rate blocks if they want to come in, and the current development situation is not ideal.

Zhang Dawei called on the national level to explore the reshuffle of shale gas mineral rights. For the blocks that have been exploited and proved by PetroChina and Sinopec, as well as the blocks with good shale gas resource endowment, oil companies hope to leave the original oil companies for exploitation, but they need to sign an agreement in advance to ensure that the specified investment amount is reached in these blocks within a certain period of time Well. The remaining blocks should be taken out for private, state-owned and foreign-funded enterprises to participate in the bidding.

technical standards lack of supervision system, and it is urgent to establish

In an interview with reporters, some oil and gas development regulatory departments of

said that an important problem in the current shale gas exploration and development process is that the supervision is relatively lagging behind, there is no special exploration and development supervision system, and most of them use the standard of conventional natural gas to supervise shale gas, but the exploration and production methods of shale gas are quite different from those of conventional natural gas. Therefore, the state should formulate supervision measures and mechanism for shale gas exploration and development as soon as possible.

take environmental protection as an example. Shale gas is a kind of clean energy, but there are many environmental risks in its exploration and development process, which is bound to bring pollution or damage to the atmosphere, groundwater, soil and vegetation. First of all, the impact on the water environment. According to the statistics of the US Department of energy, the water consumption of shale gas single well drilling is as high as 15000 cubic meters, which consumes a lot of water resources. At the same time, the fracturing fluid contains hundreds of chemical components. If the backflow fracturing fluid can not be treated in time or cause leakage, it will pollute the groundwater. Secondly, shale gas contains methane, volatile organic compounds and other harmful pollutants. Once leaked, it will cause air pollution. For example, the greenhouse gas effect intensity of methane is at least 20 times that of carbon dioxide. Third, in the process of shale gas exploitation, due to the destruction of vegetation occupied in drilling transportation and pipeline construction, it will have a negative impact on the local ecological environment. In addition, China's understanding and practice foundation of shale gas is relatively weak, and there are differences in geological conditions, distribution characteristics and pipeline network foundation of shale gas, which will face more unknown environmental risks. When reporters from

and

interviewed in Fuling shale gas field, local cadres and people expressed their concern about the environment. The local people said: I don't know whether shale gas exploitation will bring out toxic and harmful gases underground, whether the government's environmental protection supervision measures are in place, whether the environmental protection facilities and emergency measures of the mining unit are perfect Some grassroots environmental law enforcement officers of

and

told reporters that at present, there is no set of environmental assessment technical specifications specifically for shale gas exploration and development. How to calculate clean mining, whether to pollute groundwater, how to delimit noise and safe distance, and how to affect ecological vegetation Therefore, it is difficult to implement environmental supervision. For example, whether shale gas exploitation pollutes groundwater requires a 1:50000 hydrogeological survey as the basis of evaluation. However, these basic surveys have not been conducted before shale gas development, and there are no basic data, so it is impossible to monitor the changes of groundwater.

Wang Zhen, executive vice president of China Energy Strategy Research Institute, China University of petroleum, and other experts pointed out that after the diversification of investment entities in shale gas exploitation, many non oil enterprises and private capital entered the shale gas exploitation field, such as lack of self-discipline and supervision
