Deep Reservoir In-Situ Stress Inversion via Microseismic Monitoring—A Case Study of Carbonate HDR Fracturing in Northern Jiangsu
摘要
Abstract
This paper proposes a novel in-situ stress inversion method.Combined with Michael's linear stress inversion and Vavryčuk's fault plane identification technology,a complete inversion workflow for in-situ stress parameters is established by adopting multi-constrained moment tensor inversion to determine focal mechanisms.Taking the carbonate hot dry rock(HDR)reservoir in the Subei basin as a case study,90 high-quality microseismic events are selected for in-situ stress inversion.The relative magnitude of the three principal stresses follows the order of S v＞SHmax＞SHmin·The orientation of the maximum horizontal principal stress SHmax is approximately NW44°,and the stress shape factor R is 0.74.The inverted results are in good agreement with the in-situ stress data measured by the anelastic strain recovery(ASR)method from core samples of the same well,in terms of stress regime and principal stress orientation.This confirms the reliability and applicability of the microseismic-based stress inversion method in the study area.The proposed method can efficiently calculate in-situ stress parameters during fracturing and quantitatively characterize dynamic stress field evolution,which pro-vides solid technical support for deep reservoir stimulation.关键词
