基于微地震监测解释的多薄层暂堵压裂应用研究

Application and Research of Temporary Plugging Fracturing Technology for Multi Thin Layer Reservoir Based on Micro-Seismic Monitoring and Interpretation

摘要: 暂堵分层压裂技术因其工艺简单、分层灵活、适应性广、增产效果突出，在多薄层储层改造中应用越来越多，但对于它的实际转层效果一直存在争议。为了提高多薄层暂堵压裂裂缝扩展规律的认识，在胜利渤南油田义37块平台井实施了基于微地震裂缝监测的暂堵压裂现场应用研究，从工区储藏特点分析入手，提出有针对性的多薄层暂堵改造方案，并根据平台井井眼分布特点，制定了相适应的微地震裂缝监测方案。通过研究发现，暂堵压裂能够提高多薄层储层的均衡充分动用，有利于提高单井产量。

Abstract: Temporary plugging layered fracturing technology is more and more used in multi thin layer re-servoir stimulation because of its simple process, flexible layering, wide adaptability and out-standing increasing production effect, but its actual layer transfer effect has been controversial. In order to improve the understanding of the fracture propagation law of multi thin layer temporary plugging fracturing, the field application research of temporary plugging fracturing based on micro-seismic fracture monitoring is implemented in the platform well of block Y37 in Shengli Bonan oilfield. Starting with the analysis of the storage characteristics of the work area, a targeted multi thin layer temporary plugging transformation scheme is proposed, and a suitable microseismic fracture monitoring scheme is formulated according to the well distribution characteristics of the platform well. Through the research, it is found that temporary plugging fracturing can improve the balanced and full production of multi thin layer reservoirs and improve the production of single wells.
