陆相致密碎屑岩领域油气藏的勘探开发一直是世界性难题。从新场—合兴场地区的勘探开发实践出发,针对储层致密、低孔渗、薄层交互、多层叠置和强非均质性的具体特点,系统探讨了以三维地震资料为主线,结合地质、测井、录井、测试及钻井资料,研究了新的气藏综合识别和描述的物探技术,以及裂缝性气藏预测技术等。以新思路和新认识指导勘探开发,取得了川西致密碎屑岩领域油气勘探开发的重大突破。
Exploration and development of oil and gas reservoirs in the continental detrital clastic rocks has been a worldwide challenge. Based on the practice of exploration and development of Xingchang-Hexingchang area, this paper systematically discusses the three-dimensional seismic data as the main line in view of the characteristics of tight reservoir, low porosity and permeability, thin-layer interaction, multi-layer stacking and strong heterogeneity. Geology, logging, logging, testing and drilling data. The new gas reservoir integrated identification and description of geophysical techniques and the prediction of fractured gas reservoirs are studied. With new ideas and new understanding of exploration and development, has made a major breakthrough in oil and gas exploration and development in the tight clastic rocks in western Sichuan.
