Enrichment condition analysis and exploration direction of shale oil-gas in Bonan subsag
摘要
Abstract
According to the exploration practices of shale oil-gas in Bonan subsag, on the foundation of systemic analysis of producing wells of cumulative oil production and characteristics of source rocks, lithofacies, burial depth, structure and abnormal overpressure, enrichment condition of shale oil-gas is summarized. The development of effective source rocks determines the essential series of strata of shale oil-gas; the development of advantageous lithofacies (laminated argillaceous limestone lithofacies) is the basis of enrichment of shale oil-gas; the development of fracture cracks is the key of enrichment of shale oil-gas; formation of abnormal overpressure and burial depth are important factors accounting for enrichment of shale oil-gas. Lower No. 12 to Upper No. 13 layers of Es3 in Bonan subsag in which laminated argillaceous limestone lithofacies highly developed are the most enriched series of strata of shale oil-gas, it's necessary to synthesize the matched relation of various factors, arrange and evaluate comprehensively, classify and assort to verify its capability accordingly, it will lay a foundation for large-scale development of shale oil-gas. Three horizontal wells including well BYP1 have been deployed based on the study results, and the preliminary achievement has been obtained.关键词
