摘要
塔北沙参2井产油以来,对源岩的看法就一直存在分歧.作者认为由于各方取自同一原油的不同分析指标,矛盾永远无法解决。采用油气盆地地质学概念,考虑到源岩要能生成足够的烃量和有利的运移和聚集条件,即从该区的盆地演化条件出发,中生代源岩比古生代的可能性更大,而不同的源岩观点会导致不同的勘探步署决策,从而出现不同的勘探效果。
There have been different opinions on source rocks since the oil disco-very of Shacan No.2 well in north Tarim. The author considers that the problem can never be solved if different analytical indices are taken for a single crude oil. With the geological concept of hydrocarbon bearing basin, considering the evolution condition of the basin, i.e.sufficient hydrocarbons from tne source rocks, and favourable conditions of migration and accumu-lation, the source rocks is suggested to be of Mesozoic age rather than Pale-aozoic, howevei. Different ideas of source rock lead to different stragic deci-sions and arrangements and thereby different results of exploration.
