摘要
采用盆地模拟技术对川东北地区嘉二气藏古流体势演化开展研究,早中侏罗时期,流体势主要分布在55～85kJ/kg,平均流体势值为71.776 kJ/kg;至晚侏罗时期,流体势主要分布在110～155kJ/kg,平均流体势值为129.546kJ/kg;现今流体势主要分布在30～130 kJ/kg,平均流体势值为89.114 kJ/kg。研究表明,嘉二气藏古流体势分布主要受压力控制,古流体势演化具有一定的继承性;温泉场、铁山、雷音铺、铁山坡、黄龙场、亭子铺、金珠坪等低流体势分布区是川东北地区嘉二段天然气富集的有利指向区。
By adopting basin simulation technology,the evolution of paleo-fluid potential in the second member of Jialingjiang gas reservior in northeast Sichuan has been studied in this paper.In early-middle Jurassic period,the gas potential is mainly ranged from 55 kJ/kg to 85 kJ/kg,with the average value of 71.776 kJ/kg.When it went to late Jurassic period,the extent of gas potential is 110~155 kJ/kg,with its average key up to129.546 kJ/kg.Now the gas potential is 30~130 kJ/kg,with the average value of 89.114 kJ/kg.The results show that distribution of paleo-fluid potential in the Second Member of Jialingjiang gas reservior is mainly controlled by pressure.Besides that there is a certain inheritance in paleo-fluid potential evolution.It is shown by the study that such low potential regions as Wenquanchang,Tieshan,Leiyinpu,Tieshanpo,Huanglongchang and Tingzipu are the prospect areas of gas accumulation.This study provides geological reference for further exploration of the second member of Jialingjiang gas reservior.
