Research status of tectonic stress and the relationship between tectonic stress and oil-gas accumulation

This article summarizes the development of United States, Japan and other foreign combine threshing part monitoring system. Meanwhile it analyses the research status of China from two aspects of fault diagnostic and the relationship with feed rate. Which is specifically illustrated the present researching status of the fault alarm, fault warning, troubleshooting, and the relationship be-tween feed rate and travel speed, roller torque, the drive pulley oil pressure relations. At last it con-cludes the insufficiency in the present studies and points out the direction of the strengthened re-search that is model of real-time controlling about feed rate.

Insight Into

This research investigates the current state of disclosure on the climate change issues of the oil & gas companies listed on the Toronto Stock Exchange (TSX). Using a sample of 58 companies, I conduct a content analysis of their publicly available documents and develop a disclosure index. The study demonstrates that there is a significant association between the level of disclosure of climate change issues (disclosures index) and the board of director’s effectiveness (measured by Board Shareholder Confidence Index) for Canadian oil & gas companies. This study also explores the association between firms’ value and the level of climate change disclosure. The empirical evidence indicates that the investors take the extent of disclosures on climate changes into considerations when they assess the market value of the firms. This study contributes to environmental accounting literature because it examines the relationship between climate change disclosures and corporate governance. From a practical point of view, the outcome of this analysis will help Canadian Securities Administrator (CSA) to have insight into climate change disclosures practices and provides a frame of references for developing related disclosures requirement.

The Relationship

Purpose. This study analyzes the oil industry, gas and biofuels in order to identify associations between corporate governance practices with capital structure, risk and performance.Methodology. These data were verified through 3SLS models (Three-Stage Least Squares). For this, we used a data set composed of 19 companies, for a panel data analysis in the period 2005-2009.Findings. The results suggest a negative association between leverage and corporate governance company level, supporting the substitution hypothesis, according to which the leverage works as a governance substitute. Also they did not reject the hypothesis that the greater the governance practices, greater market performances and accounting of these companies, as well as reduces the market risk.Limitations. The main limitation of this research is the sample size, 19 companies, with particular focus on an industry, reducing the generalizability of the results.Originality/Value. This study sought to contribute to the understanding of the relationship between corporate governance, capital structure, performance and risk; specifically for the oil, gas and biofuels in Brazil, an important and understudied emerging market.

Second Period

In order to clarify the relationship between fractures and gas accumulation, using data of cores, image logs and experimental analysis, we analyzed the fracture genetic types, development characteristics, controlling factors, distribution rules and formation periods. And then, by combining the evolution of source rock, activity periods of gas source faults and the evolution of cap rock sealing ability in the study area, we discussed the relationship between tectonic fractures and gas accumulation. The results show that there exist primary fracture and secondary fracture in the volcanic rocks of Yingcheng Formation in Songliao Basin. Between the two types, the secondary facture is dominant. Tectonic fractures are controlled by lithology, lithofacies and faults in the plane, and by unconformities vertically, with the characteristics of distribution of cycles. The tectonic fractures formed in three phases, wherein the second period coincides with the hydrocarbon generation peak period. During the second period, gas source faults are active and cap rock had a better sealing ability. This period is the main hydrocarbon accumulation stage in the study area.
