改革开放以来,尤其是上世纪90年代以来,我国贯彻落实了对内改革,对外开放的基本基本方针,经济和社会得到高速发展,尤其是石油产业作为我国国民经济的支柱产业也得到了蓬勃发展。地质勘探、气藏沉积特征分析是油田开发的重要组成部分。本文对鄂尔多斯盆地气藏沉积特征展开深入探究,重点对油气藏发育控制因素,岩相古地理、岩溶古地貌、沉积相带、后期埋藏的充填和溶蚀机理进行科学分析。收集油气藏分布信息,提高油田开采质量,效率,节约钻探成本,切实加强对盆地沉积学等基础研究,利用先进计算机技术、高精度、高分辨手段,促进鄂尔多斯地区气藏勘探开发走向可持续发展道路。
Since the reform and opening up, especially since the 90s of last century, our country has implemented the basic basic guidelines for internal reform and opening up to the outside world and the economy and society have enjoyed rapid development. In particular, the petroleum industry has also thrived as the pillar industry of our national economy . Geological exploration, gas reservoir sedimentary characteristics analysis is an important part of oilfield development. In this paper, the sedimentary characteristics of gas reservoirs in the Ordos Basin are explored in depth, and the control factors of reservoir development, lithofacies palaeogeography, karst palaeogeomorphology, sedimentary facies belt, filling and dissolution mechanism of later burial are analyzed. Collect information on the distribution of oil and gas reservoirs, improve the quality and efficiency of oil exploration, save drilling costs, effectively strengthen basic research on basin sedimentology, and promote the exploration and development of gas reservoirs in Erdos area towards sustainable development by using advanced computer technology, high-precision and high-resolution methods the way.
