摘要
该文以王徐庄油田沙一下生物灰岩为例,详细论述了储集层裂缝的判别。通过利用地应力分布状态、构造形迹特征判定裂缝展布方向;采用示踪剂监测、电位法井间监测和油水井注采动态关系分析井间裂缝的连通性及展布方向;依据岩心微观分析资料、电测井曲线综合响应进行单井裂缝层段的识别与划分。对王徐庄油田下一步开发工作具有指导作用。
Taking Shayixia bio-limestone of Wangxuzhuang oilfield as an example, the paper gave the reservoir fracture discriminant in great details. Fracture expanding di rection was discriminated by making use of formation stress distribution state a nd structural expression features, connectivity and expanding direction of well- to-well fractures were analyzed by adopting tracer monitoring, electrometric met hod for well-to-well monitoring and injection-production dynamic relationship of oil-water well, and individual well fracture zones were identified and divided based on core micro-analysis data and comprehensive response of electric logging curves. The above discriminant had guiding functions to Wangxuzhuang oilfield n ext stage development.
