【Chemical Machinery and Equipment Network Industry News】On October 18, 2022, Sinopec announced that the Southwest Petroleum Bureau has made a major breakthrough in shale gas exploration in the Sichuan Basin, with the evaluation and implementation of geological resources reaching 387.
8 billion cubic meters, and the resources of the entire shale section exceeding 1 trillion cubic meters
.
It is reported that this is the first major breakthrough
in shale gas exploration in the Cambrian Xiaozhusi Formation strata in China.

As of April, the results released by the final results acceptance meeting of the Sichuan Shale Gas Resources Investigation and Evaluation Project showed that the geological resources of shale gas in Sichuan Province exceeded 40 trillion cubic meters, the technical recoverable resources were about 9 trillion cubic meters, and the economically recoverable resources were about 5 trillion cubic meters
.
Sichuan also said that it will fully build a national natural gas (shale gas) 100 billion cubic meter production capacity base and Sichuan Province's "5+1" industrial system
.

Looking back at China's discovery in shale gas exploration, Sinopec Jianghan Oilfield also reported the forecast news of more than 100 billion cubic meters of shale gas reserves in January this year
.
It is reported that in the Lichuan Hongxing area of Enshi Prefecture, Hubei Province, the first batch of shale gas reserves is predicted to be 105.
103 billion cubic meters
after trial mining.

For the research of shale gas, China can probably be traced back to 2004, in 2009 China launched the "Shale gas resource potential and favorable areas in China's key areas" project, in 2010, China launched the "Sichuan-Chongqing-Qian-Hubei Shale Gas Investigation Pilot Experimental Area" work, Xiayangzi Suwan Zhejiang area to carry out shale gas resources investigation, northern region (North China, Northeast and Northwest) shale gas resources preliminary investigation and research, in 2011 in Sichuan-Chongqing-Qian'e carried out 5 projects pilot tests.
In 2012, it achieved a breakthrough
in the commercial development of shale gas exploration in China.

In 2017, the land department estimated that China's shale gas recoverable resources were about 25 trillion cubic meters, and the national production capacity exceeded 10 billion cubic meters, and the industry agreed that shale gas had entered an inflection point
in commercial production.
In 2018, the Fuling shale gas field has been built into a demonstration model, with an annual production capacity of 10 billion cubic meters built on schedule, and it is no longer a dead talk to fully enter the era of commercialization, and the cumulative proven reserves in the country reached more than
900 billion cubic meters at that time.

In 2020, the cumulative production of shale gas in China's Sinopec Fuling shale gas field exceeded 30 billion cubic meters, and in the same year, the development and construction of the deep 100 billion cubic meter shale gas field - Weirong shale gas field project also came with good news, and the prospects of the domestic shale gas market are promising
.
In this field, China has also staged the "Chinese speed" of shale gas development, and the "Chinese quality"
cannot be left behind.

In order to standardize the development of shale gas industry, "Shale Gas Geological Evaluation Methods" (GB/T 31483-2015), "Shale Gas Technical Requirements and Test Methods" (GB/T 33296-2016), "Shale Gas Development Scheme Preparation Technical Specification" (GB/T 34163-2017), "Optimal Methods for Marine Shale Gas Exploration Targets" (GB/T 35110-2017), "Shale Gas Environmental Protection Part 1: Drilling Operation Pollution Prevention and Disposal Methods" (GB/T).
39139.
1-2020), "Rapid Analysis of Shale Gas Components Laser Raman Spectroscopy" (GB/T 39540-2020), "Technical Code for Shale Gas Reservoir Description" (GB/T 39541-2020) and other standards have been implemented successively, "Shale Gas Exploration and Development Oil Baserock Chip Treatment Methods and Control Indicators" (GB/T 41518-2022), "Requirements for Water Resources Protection in Shale Gas Development Process" (GB/T 41519-2022), " Shale gas recoverable reserve assessment method (GB/T 41614-2022), "Technical requirements for the admission of shale gas development evaluation data" (GB/T 41613-2022), "Technical specification for shale gas well production forecast" (GB/T 41612-2022), "Shale gas terms and definitions" (GB/T 41611-2022) will also be officially implemented
on November 1.

It is reported that the "natural gas - upstream field - slippery water drag reduction performance test method" successfully passed the project vote, included in the ISO international standard formulation plan and officially started the formulation work, which is the first international standard established in the domestic shale gas field, marking that China has taken an international step
in the shale gas field.

It's a joy, there's always good news
.
It is true that China's shale gas exploration and research work started late, but it is an indisputable fact
that we have "explored a theoretical system and technical series of shale gas exploration and development with Chinese characteristics, and achieved a major breakthrough and rapid rise in China's shale gas exploration and development".
In the critical period of achieving the dual carbon goal, the large-scale development and utilization of shale gas is expected to make greater contributions
to the new energy system at the support point of energy supply-side reform.

Shale gas

A kind of natural gas rich in organic matter, mature dark mud shale or high carbon mud shale due to organic matter adsorption or cracks and matrix pores in the rock, so that it stores and preserves certain commercial value of biogenesis, pyrolysis and mixed causes of the two, has the advantages of long exploitation life and long production cycle, and the composition is mainly methane, which is a clean and efficient energy resource and chemical raw material
