摘　　要：【研究目的】为了明确断控缝洞型碳酸盐岩储层地应力分布特征,提高碳酸盐岩油气的勘探效率和开发效益,【研究方法】基于地质信息、钻井信息、地震资料及地震属性分析,以塔里木盆地富满油田FY210断裂带为例,开展地应力场建模,明确地应力分布模式,分析断裂力学有效性,并提出基于地应力分析的储层品质评价方法和提产对策。【研究结果】结果表明:①断控缝洞型碳酸盐岩储层的非均质性强,断层、裂缝、孔洞造成局部应力场发生异常变化,洞体的地应力场呈“壳式”分布特征,外部强应力壳体表现为应力集中,内部低值区为有利储层体,可根据地应力变化反推断层-裂缝-孔洞发育情况;②高应力部位属于不利的钻探目标,具高应力特征的储层渗透性较差,且钻井过程中会出现井壁垮塌,应通过大规模改造、加深或者侧钻方式避开这类部位;③除常规岩石物理参数外,地应力、断裂活动性、可压裂性等地质力学属性也是影响断控缝洞型碳酸盐岩储层品质和产能的重要因素。【结论】超深断控油气藏井位部署和井轨迹优化应充分考虑地应力相关因素,并兼顾储层改造效率,促进单井提产和油藏效益开发。In order to clarify the distribution characteristics of in-situ stress in fault-controlled fracture-vug reservoirs and improve the exploration efficiency and development benefits of carbonate reservoir.Based on geological information,drilling information,seismic data,and seismic attribute analysis,this article conducts a modeling of the in situ stress field in the FY210 fault zone of the Fuman Oilfield,clarifies its in situ stress distribution mode,analyzes the effectiveness of fracture mechanics,and proposes a reservoir quality evaluation method and production improvement strategy based on in situ stress analysis.The results indicate that:①the heterogeneity of fault-controlled fracture-vug reservoirs is strong,and faults,fractures,and pores cause abnormal changes in local stress fields.The in situ stress field of the cave body shows a"shell like"distribution feature,and the external strong stress shell shows stress concentration.The low value area inside is a favorable reservoir body,and the development of fractures,pores,and caves can be inferred based on the changes of in situ stress.②High stress areas are unfavorable drilling targets,and reservoirs with high stress characteristics have poor permeability.During drilling,wellbore collapse may occur,and such areas should be avoided through large-scale renovation,deepening,or lateral drilling.③In addition to conventional petrophysical parameters,geomechanical properties such as in-situ stress,fracture activity,and fracturability are also important factors that affect the quality and productivity of fracture-controlled vuggy carbonate reservoirs.Well placement and well trajectory optimization should fully consider factors related to in-situ stress,while also taking into account reservoir reconstruction efficiency to promote single well production and reservoir benefit development.
