摘要

摘要: 文留地区是渤海湾盆地典型的煤成气区之一，随着勘探认识的不断深入，研究区煤成气运聚成藏过程的精细刻画仍需完善。运用流体包裹体技术分析文留地区煤成气成藏时间，基于断层活动特征明确研究区输导体系演化特征，根据断—盖组合关系及烃类流体包裹体丰度（GOI）测试结果分析气藏保存条件，最终明确文留地区煤成气成藏过程。研究表明，文东断层为研究区气源断层，其输导供烃条件可用断层输导效率系数（FTEC）进行量化表征，评价结果表明研究区具有优越的气源供给条件；文留地区煤成气来源于临近的洼陷带，煤成气在东营组沉积时期沿文东断层垂向运移至石炭—二叠系和沙四段储层聚集成藏，东营末构造抬升期气藏受构造运动影响而发生少量天然气散失。

Abstract: The Wenliu area is one of the typical coal-formed gas accumulation zones in the Bohai Bay Basin. With the deepening of exploration, the fine characterization of the coal-forming gas accumulation process in this area still needs to be improved. The fluid inclusion technology was used to analyze the coal-formed gas accumulation date in Wenliu area. Based on the analysis of fault activity, the evolution characteristics of the transport system in the study area were determined. The gas-fluid inclusion abundance (GOI) test were used to analyze the gas preservation conditions, and finally the process of coal-formed gas accumulation in Wenliu area was carried out. The results show that the Wendong fault is a gas source fault in the study area, and its hydrocarbon supply conditions can be characterized by the Fault Transport Efficiency Coefficient (FTEC). The study area has superior gas supply conditions; the coal-formed gas in Wenliu area originates from the adjacent deep sag zone, and vertically transports along the Wendong fault to the Carboniferous-Permian and the Es4 sandstone reservoirs in the trap during the sedimentary period of the Dongying Formation. Small amount of the coal-formed gas loss occurred during the tectonic uplifting movements in the late sedimentary period of the Dongying Formation.
