Thermal Evolution of Organic Matter in Source Rocks—Experimental and Scanning Electron Microscopic Studies

Five major froms(lamellar,banded,crack-like,dissceminated and segregated encrustation(of organic matter distribution in sourc rocks have been revealed under scanning electron microscope by using the heavy metal staining technique.The degree of organic impregnation is related to the amount of liquied hydrocarbons in the rocks,and from this relationship a rough estimation of organic matter can be made on the basis of electron microscopic observations.In conjunction with experimental studies it has been found that the distribution forms of organic matter are a function of its maturity in the process of thermal evolution and accordingly some microscopic criteria can be developed for the assessment of source rocks.     

边底水疏松砂岩气藏气井合理产量标定方法研究

由于边底水疏松砂岩气藏特殊的开发地质条件,如何准确地标定此类气藏气井的合理产量,在国内外一直没有统一的标准。笔者从云南保山盆地永铸街气田和陆良盆地大嘴子气田,第三边底水疏松砂岩气藏气的合理产量标定入手,结合两气田 试采取得的成果与国内外相关的微要文献,探讨边底水疏松砂岩气藏气井合理产量的标定方法,取得了较好的实际效果。
