Distribution patterns and integrated exploration strategy for conventional and unconventional hydrocarbon resources
摘要
Abstract
Evaluation of hydrocarbon resources provides a crucial strategic foundation for accurately quantifying resource potential,scientifically planning exploration activities,and safeguarding the national energy security.Since the implementation of China's 14th Five-Year Plan,the hydrocarbon exploration in China has gradually shifted from focusing solely on conventional resources to placing equal emphasis on both conventional and unconventional resources.Based on advances in the theoretical understanding,techniques and methods,and practical applications of the integrated evaluation of conventional and unconventional hydrocarbon resources,we examine the configuration relationships and distribution patterns of these resources within the evaluation areas and map favorable exploration targets in major petroliferous basins of China,gaining considerable achievements.Specifically,an innovative integrated evaluation technique for conventional and unconventional hydrocarbon resources has been developed based on TSM basin modeling,overcoming the limitations of traditional evaluation methods.Accordingly,it has been proposed that understanding the differential evolutionary patterns of the hydrocarbon generation,retention,and expulsion of various source rocks is the key to integrated resource evaluation.The new technique reveals the genetic relationship and synergistic evolution process across the whole sequence of hydrocarbon resources,providing an important guidance for integrated resource evaluation and decision-making for resource exploration.What's more,the overall resource structure manifests as a decrease in conventional original in-place resources alongside a substantial increase in unconventional original in-place resources.These characteristics result in a resource configuration featuring balanced proportions of oil and gas resources,along with stable conventional resources and increased unconventional resources.This analysis also confirms that major basins remain the primary domain for significant exploration breakthroughs.At last,given the discovery rates and distribution characteristics of hydrocarbon resources,the orderly progression from conventional to unconventional oil and gas provides a robust resource foundation for stabilizing oil production while increasing gas output("stabilizing oil,increasing gas").Primary targets for future integrated exploration of conventional and unconventional hydrocarbon resources include the Paleogene strata of the Bohai Bay Basin,the Cambrian,Permian,and the Jurassic strata of the Sichuan Basin,and the Carboniferous-Permian and Triassic strata of the Ordos Basin.关键词
