1970―1978年笔者在塔里木油气地质调研中首次提出古生代有发育的烃源岩，1984年沙参2井实现了古生代海相油田的首次重大突破。1992年通过多个古生代油气田深入研究建立了古生代海相油气成藏理论。其理论内涵：叠加复合盆地成藏，多时代多层系生油，多期成藏，多时代多类型储盖组合，多成藏模式，油气主要分布在古隆起、古斜坡、断裂带和不整合面附近。

In the Tarim petroleum geology investigation from 1970 to 1978, the author proposed for the first time that there was developed source rock in the Paleozoic era. A great breakthrough of Paleozoic marine hydrocarbon field was achieved in Shacan No. 2 well in 1982. Through deep research of many Paleozoic marine hydrocarbon fields, the author proposed Paleozoic marine hydrocarbon accumulation theory in 1992, which includes superposition composite basin accumulation, multi-era and multi-layer series petroleum generation, multi-stage accumulation, multi-era and multi-type reservoir-seal assemblage, multi-accumulation model and that hydrocarbon is mainly distributed around paleo-uplift, paleo-slope, fault zone and unconformity.
