摘要
四川盆地有丰富的天然气资源,目前在中、深层获得的探明储量仅占计算资源量的3.4%.尚有96.6%的巨大资源量有待人们去发掘。中、深层气层由于储层物性一般较差、许多地方具有异常高压,在后期燕山-喜山构造运动的强烈改造下,易导致天然气沿断裂和裂缝向上运移、聚集,形成浅层次生气藏。据地质资料分析,盆地内的川东、川南,特别是川西地区均具有形成浅气藏的有利地质条件,是勘探浅气藏的有利地区。四川当前天然气能源供需矛盾突出,因此加强浅层气勘探势在必行,当前可选择川西地区作为勘探、开发浅层气的试验区,这里不仅具有形成浅气藏的有利地质条件,而且有促进四川经济发展的地域优势,若在勘探、开发浅气藏上取得成功,必将对全川浅层气的开发产生重大影响。因此,这是解决四川天然气能源严重短缺的一项重要策略,望能引起决策者重视。
As the reservoir Physital characteristics Of middle-deep bearing formation in Sichuan Basin are wores, abnormal high pressures exist in many areas. It is easy making gas go up along fractures and accumulate to form shallow secondary gas pools. In the light of analysing geological data,East Sichuan,South Sichuan,especially West Sichuan have the conditions of forming shallow po pools. So Sichuan Basin is favourable for exploring shallow gas pools. West Sichuan is of the regional superiority of promoting the economy devclopment in sichuan. The important measure of selecting West Sichuan as the pilot area of exploring and developing shallow gas to solve the energe shortage problem in Sichuan is proposed out.
