基于压裂-返排数据驱动的致密储层缝网诊断技术发展现状与展望
Current state and prospects of fracturing-flowback-based data-driven fracture network diagnostic technology for tight reservoirs
摘要
Abstract
Fracture network diagnosis of tight reservoirs is an important aspect of evaluating fracturing effect.The di-agnostic results can not only serve to assess the fracture network transformation,but also provide a theoretical basis for optimizing subsequent fracturing designs.In light of the current insufficient utilization of fracturing-flowback da-ta in tight reservoir fracture network diagnostics,a comprehensive review and analysis of the current situation in frac-turing-flowback-based data-driven fracture network diagnostic technology for tight reservoirs was conducted.Key existing issues in tight reservoir fracture network diagnostics were discussed,and the focus areas for future develop-ment of data-driven fracture network diagnostic technologies using fracturing and flowback data were identified.The study shows that current tight reservoir fracture network diagnostic techniques exhibit lag effects,non-uniform frac-ture closure effects,and inter-well interference effects in closely spaced volume-fractured wells.It is necessary to establish a full-cycle(fracturing-shut-in-flowback)fracture network diagnostic method,develop diagnostic tech-niques based on pressure decline curves during shut-in,and advance fracture network diagnostic techniques under inter-well interference conditions.The results of this study provide new ideas and technical support for the develop-ment of fracturing-flowback-based data-driven fracture network diagnostic technology in tight reservoirs.关键词
