深层-超深层碎屑岩地应力测井评价及其控储效应
Logging evaluation of in situ stress and its effects on reservoir quality in deep and ultra-deep clastic rock
摘要
Abstract
In situ stress significantly controls the quality of deep and ultra-deep tight sandstone reser-voirs.It is important to clarify the stress-controlled storage effect for the comprehensive evaluation and pre-diction of deep and ultra-deep tight sandstone reservoirs.In this paper,basic characteristics of the Creta-ceous Bashijiqike Formation in the Zhongqiu area of Kuqa Depression are revealed through analysis of cores and thin sections,the logging evaluation of in situ stress is realized,and the control of in situ stress on reservoir quality is clarified.The results show that the reservoir is mainly made of medium-fine sandstones,which is dominated by primary intergranular pores,with less secondary pores and occasional fractures.The fracture surface morphology is picked up by image logging,and the logging calculation of fracture parame-ters is realized.Evaluation of in situ stress is completed through logging data,and the coupling control re-lationships between in situ stress,and matrix pores and fracture parameters are revealed.The reservoir classification and evaluation of the Bashijiqike Formation are realized by combining physical parameters with in situ stress.High-quality reservoirs are mainly developed in fractured zones and intervals with low in situ horizontal stress differences.Through logging evaluation of in situ stress combined with calculation of reservoir parameter,the reservoir quality classification evaluation and high-quality reservoir logging predic-tion can be realized.The research results may provide technical support for the comprehensive evaluation of deep and ultra-deep tight sandstone reservoirs and the prediction of favorable zones.关键词
