| 1 | Chlorite cement and its effect on the reservoir quality of sandstones from the Panyu low-uplift,Pearl River Mouth Basin显示文摘Based on porosity and permeability measurements,mercury porosimetry measurements,thin section analyses,SEM observations,X-ray diffraction(XRD) analysis and granulometric analyses,diagenetic features of reservoir sandstones taken from the Zhuhai formation in the Panyu low-uplift of the Pear River Mouth Basin were examined.This study shows that chlorite cements are one of the most important diagenetic features of reservoir sandstones.The precipitation of chlorite was controlled by multiple factors and its development occurred early in eo-diagenesis and continued till Stage A of middle diagenesis.The precipitation of chlorite at the early stage was mainly affected by the sedimentary environment and provenance.Abundant Fe-and Mg-rich materials were supplied during the deposition of distributary channel sediments in the deltaic front setting and mainly in alkaline conditions.With the burial depth increasing,smectite and kaolinite tended to be transformed into chlorite.Smectite cements were completely transformed into chlorite in sandstones of the studied area.Volcanic lithics rich in Fe and Mg materials were dissolved and released Fe2+ and Mg 2+ into the pore water.These cations precipitated as chlorite cements in middle diagenesis in an alkaline diagenetic environment.Chlorite coatings acted as porosity and permeability,thus helping preserve cements in the chlorite cemented sandstones.The reservoir quality of chlorite cemented sandstones is much better than sandstones without chlorite cements.Chlorite cements play an important role in the reservoir evolution that was mainly characterized by preserving intergranular porosity and forming better pore-throat structures of sandstones. | Chen Guojun Du Guichao Zhang Gongcheng Wang Qi Lv Chengfu | 2011 | Petroleum Science2011，8，2： | 14 |
| 2 | Greenhouse gas emissions from oilfield-produced water in Shengli Oilfield,Eastern China显示文摘Greenhouse gas(GHG) emissions from oil and gas systems are an important component of the GHG emission inventory. To assess the carbon emissions from oilfield-produced water under atmospheric conditions correctly, in situ detection and simulation experiments were developed to study the natural release of GHG into the atmosphere in the Shengli Oilfield,the second largest oilfield in China. The results showed that methane(CH4) and carbon dioxide(CO2) were the primary gases released naturally from the oilfield-produced water.The atmospheric temperature and release time played important roles in determining the CH4 and CO2emissions under atmospheric conditions. Higher temperatures enhanced the carbon emissions. The emissions of both CH4 and CO2from oilfield-produced water were highest at 27°C and lowest at 3°C. The bulk of CH4 and CO2was released from the oilfield-produced water during the first release period, 0–2 hr, for each temperature, with a maximum average emission rate of 0.415 g CH4/(m3·hr) and 3.934 g CO2/(m3·hr), respectively. Then the carbon emissions at other time periods gradually decreased with the extension of time. The higher solubility of CO2 in water than CH4 results in a higher emission rate of CH4 than CO2over the same release duration. The simulation proved that oilfield-produced water is one of the potential emission sources that should be given great attention in oil and gas systems. | Shuang Yang Wei Yang Guojun Chen Xuan Fang Chengfu Lv Jiaai Zhong Lianhua Xue | 2016 | Journal of Environmental Sciences2016，28，8： | 2 |
