“…Technical innovation plays a vital role in its green growth process. A series of techniques were carried out in Huabei Oilfield, including 2D seismic fine structure interpretation of coal bed methane, enrichment region evaluation and well deployment, solving the problem of strong adsorption capacity and high gas content in high rank coal seam [46]. The petroleum equipment is one of the key factors of energy saving and emission reducing.…”

Abstract:As a pillar industry in supporting Chinese economy, Chinese manufacturing industry consumes a large amount of energy and causes serious environmental pollutants. Better understanding the greening level of manufacturing industry is important to promote its green growth. Hence first this study, measures the green growth efficiency for Chinese manufacturing industries by applying the EBM measuring model; second, to better understand the differences and similarity in green growth among those industries, this study categorizes those industries into different types by using cluster analysis. The result shows that within the past nine years, green growth efficiency value for Chinese manufacturing industries rises steadily year by year, and Chinese manufacturing industries have huge promotion potentials in resource saving and environment pollutant reduction. And the characteristics of each different type are analyzed. Finally, policies and suggestions are put forward to promote the green growth of manufacturing industries in China. This study objectively evaluates the green growth level of Chinese manufacturing industry, which is helpful to understand the status quo and also explore green growth path for Chinese manufacturing industries.

“…Rosneft and Lukoil take the third and fourth places by market share, respectively. The top three leaders in gas production among Chinese companies are CNPC, Sinopec and CNOOC, which hold the most substantial part of natural gas reserves in China, with total reserves amounting more than 80 percent of the national gas industry [7]. CNPC takes first place in terms of gas production, which accounts for more than 60% of gas production in China.…”

Over the past ten years have seen ambiguous situation concerning China and Russia gas companies. On the one hand, companies’ reports show conservative policies and sustainable growth in the coming years, on the other hand, companies’ financial performance suggest another situation because of insufficient level of financial indexes that reflects the inconsistency of existing sustainable growth approaches. These indicates relevance of the research concerning China and Russia gas market companies’ financial sustainable growth in conditions of global economy and investment policy implementation. The main purpose of the Research is to analyze China and Russia gas market companies’ financial growth strategy by means of Geniberg Z – matrix as well as enhanced Financial Sustainability Indicators System indexes by identifying which indicators have a greater influence on Sustainable Growth Rate. It is found that ROCE, ROFA, CR, DOL, ROL influence on Russian gas market companies’ SGR, and ROCE, WACC, ROL, CG Dummy influence on Chinese gas market companies sustainable growth.

“…In addition, microbial dolomitization provides a new implication for dolomite formation (Vasconcelos, McKenzie, Bernasconi, Grujic, & Tiens, ; Wright, ). The carbonate rocks of the Lower Palaeozoic are the major gas‐producing formation, accounting for a total of nearly 23 TCF (trillion cubic feet) in the Ordos Basin, China (Yang, Liu, Huang, Lan, & Wang, ). Most of the carbonates are dominated by dolomites in the Ordovician formations, and geologists have established numerous models of dolomitization about Ordovician dolomite, which mainly include penecontemporaneous dolomitization (Su, Chen, & Xu, ), dorag dolomitization (Yang & Bao, ; J. X. Zhao, Chen, Zhang, Liu, & Fu, ), seepage–reflux dolomitization (X. Y.…”

There are widely developed carbonate formations in the lower Palaeozoic, Ordos Basin, China. However, previous studies have paid more attention to the Ordovician formations and largely ignored the Cambrian formations, which also have a larger sediment thickness. Recently, with the continuous discovery of dolomite gas fields in the Ordovician Majiagou formation, more investigations have begun to focus on the deeper dolomite in the Cambrian Sanshanzi Formation (Є3s). This study looks into the origin of the dolomite through a combination of petrology, major–trace elements, and stable isotope and rare earth element (REE) analysis of samples from five outcrops. The results show that the main dolomite types in the study area are dolarenite (Type 1), micrite‐fine crystalline dolomite (Type 2), and medium crystalline dolomite (Type 3). The δ13C values and δ18O values of each dolomite formation are close to those of seawater‐derived dolomite and have slightly higher Na2+ concentrations, suggesting that dolomite formation is closely related to the denser seawater. The REE compositions are characterized by enrichment for light REEs and depletion for heavy REEs, exhibiting an apparent negative Eu anomaly and a slight negative Ce anomaly, indicating that the dolomites of the Є3s may form in a weak‐reduction to the weak‐oxidation environment. The total REE (ΣREE) concentrations of Type 3 dolomites are lower than other types, suggesting that those dolomites may mean that the REEs are lost during the diagenesis. Type 1 dolomite has lower MgO and CaO values and a higher Mn2+ concentration than the other two types of dolomites, indicating that Type 1 dolomite suffered the action of atmospheric fresh water. Type 2 dolomite has lower Mg and Ca values than Type 3 dolomite, suggesting that Type 3 dolomite has a higher dolomitization degree. Further study into the combined palaeogeographical background confirms the dolomitization model of the study area: Type 1 and Type 2 dolomites may have been formed by penecontemporaneous or seepage–reflux dolomitization during early‐stage diagenesis. Subsequently, stratigraphic uplift lead to the Type 1 dolomite suffering the action of atmospheric fresh water, but there was no dorag dolomitization. Type 2 dolomite became the main dolomite type by seepage–reflux dolomitization in this period. Later, Type 2 dolomite was converted into Type 3 dolomite during progressive burial.
