深层—超深层碳酸盐岩储层成因实验技术及应用
Experimental techniques for the genesis of deep to ultra-deep carbonate reservoirs and their applications
摘要
Abstract
Targeting the deep to ultra-deep carbonate reservoirs,which are characterized by high temperature and high pressure(HTHP),multi-stage complex tectonic-fluid modifications,and complicated reservoir-formation and accumulation processes,this study has developed a diagenesis-porosity evolution reconstruction technique based on the"Fluid-Time-Temperature-Pressure"(FTtP)framework,and independently designed a visual simulation apparatus for ultra-deep reservoirs under HTHP conditions across multiple tectonic stages.Experimental investigations are conducted from both inversion(backward reconstruction)and forward simulation perspectives,aiming to reveal the genetic mechanisms and distribution patterns of porosity in deep to ultra-deep carbonate reservoirs.Specifically:(1)The FTtP-based diagenesis-porosity evolution reconstruction technique integrates over ten elemental and isotopic geochemical analytical methods,obtaining a suite of high-precision,multi-parameter,in-situ geochemical data.It addresses the critical challenges of constrainting the time,temperature,pressure,and fluid properties of diagenetic products,thereby enabling the reconstruction of the formation processes and preservation mechanisms of porosity in deep to ultra-deep carbonate reservoirs.(2)The visual simulation apparatus integrates multiple functionalities,including ultra-HTHP conditions,multi-cycle internal dissolution,real-time visualization of dissolution processes,and on-line monitoring of permeability and fluid composition.It enables forward simulation experiments of dissolution-precipitation processes across tectonic stages under near-real geological conditions,dynamically reproducing the formation and evolution of pores,and consequently revealing the genetic mechanisms,scales,and distribution patterns of reservoir porosity.The advancement and application of the above technologies have provided critical experimental support for the evaluation and prediction of deep to ultra-deep carbonate reservoirs.In the future,experimental testing techniques will continue to undergo iterative upgrades—elemental and isotopic analyses will evolve from bulk-rock analysis to in-situ micro-texture characterization,from solution-based methods to laser-based techniques,and from laser spot analysis to laser mapping/imaging.Meanwhile,the functionality of simulation apparatus will advance toward integrated modeling of hydrocarbon generation,reservoir formation,and accumulation in ultra-deep settings,continuously providing experimental support for deep petroleum exploration.关键词
