在1996年南方油气勘探工作会议上的讲话(主要部分) 努力实现南方海相油气勘探重大突破

南方地质条件有四方面的特点:碳酸盐岩区与特提斯域有关,具有良好的含油气前景;叠置在碳酸盐岩区上的南、北两大前陆盆地带,对古生界原型盆地烃源岩的演化、油气藏形成和保存起到重要作用;南方海相地层具有丰富的烃源岩;后期多旋回构造运动,使南方海相油气系统变得十分复杂。南方油气选区评价的关键是保存条件,在含油气系统中“保存单元”是优选勘探目标的重要依据。“九五”期间,一要主攻中、下扬子区,获重大突破;二要积极做好滇黔桂地区三个盆地(南盘江盆地、楚雄盆地、十万大山盆地)的预探;三要进一步搞好区域评价。

Try Our Best to Make an Important Breakthrough of Oil-Gas Exploration of Marine Sequence in South China

The characteristics of the petroleum geological conaitions of South China are as follows:The marine carbenate rock region of South China is related with Tethys Tract,has a brisht oil-gas prospectinsg:the southern and northern foreland basin zones overlying the marine sequence of South China have a great influence on the evolution of source rock of Paleozoic prototype basins,oil- gas pool formation and preservation;the source rock of marine sequence of South China is rich;the marine petroleum systems of South China are complicated because of the multistage and multicycle structural movements.The key problem of assessment of a target in southern China is preservative condition.The preservative unit of the petroleum system is the most important basis for a target whether to be taken or not.In the course of Ninth-Five-Year Plan,Middle and Lower Yanszi is firstly taken as a key target,try to get marked breakthrough in it;meanwhile make great efforts to set ready of preliminary exploration in three regions of Yunnan,Guizhou and Guangxi,namely Nanpanjiang,Chuxiong.Shiwandashan basins;to do good job of regional assessment is the third task.
