运用粒度参数开展对沉积环境的研究工作,是近年来国内外石油资源勘探和开发迅猛发展的结果、对石油来说,查明生油、储油的有利相带,研究沉积环境有重要的理论和实际意义。随着寻找构造圈闭油田的机会逐渐减少,岩性、地层、古地貌圈闭的油田已占重要地位。国际石油会议所确定的世界上256个大油、气田中,有43％的石油和30％
The use of particle size parameters to carry out research on sedimentary environment is the result of the rapid development of petroleum resources exploration and development both at home and abroad in recent years. For petroleum, it is important to find favorable facies belts of oil generation and oil storage and to study sedimentary environment And practical significance. With the search for the trapped oil fields gradually reduced opportunities, lithology, stratigraphy and paleogeography trapped oil fields have taken an important position. International Oil Conference identified 256 of the world’s largest oil, gas fields, 43% of oil and 30%
