摘　　要：在储集体预测的基础上,以塔北地区奥陶系露头为指导,将哈拉哈塘油田哈601井区油藏洞穴按成因细分为暗河管道厅堂洞穴、断裂明河双控洞穴和断控洞穴3类。针对缝洞单元划分的难点,应用静态储集体预测和数值试井两种方法确定缝洞单元边界,明确了内幕区缝洞单元主控因素为断裂和良里塔格组古地貌古水系。依据缝洞体规模、储量、能量指标、成因类型、压力水平等因素,建立了适用于研究区的缝洞单元评价标准,对有井控制单元及无井单元进行了综合评价,为哈拉哈塘油田下一步的井位部署与开发调整提供参考。Taking HA601 wellblock in Halahatang oilfield as an example, based on the reservoir prediction, guided by the Ordovician out-crop in Tabei area（northern Tarim basin）, this paper presents three genetic types of fractured-vuggy reservoir formed in the karstification,including tubulose underground river caves, caves controlled by faults and rivers, caves controlled by faults; considering the difficulties infracture-vug unit division, it provides two divisive methods of static reservoir prediction and numerical well test to confirm the boundary offracture-vug units. The study indicates that the key factors for controlling fracture-vug units in carbonate interstratum area is river systemsin Lianglitage formation and faults. Based on the scale of reservoir body, geological reserves, energy index, genetic type and pressure level,it establishes the evaluation criterion for fracture-vug units in carbonate interstratum area, and applies it to all the well-controlled and non-well-controlled units, which provide a reference for well deployment and development adjustment of Halahatang oilfield in the future.
