摘要
区域地质和石油地质分析证明塔中地区基本具备形成大油气田的必要条件。塔中隆起形成早，后期持续稳定发展，下古生界巨型构造发育；石炭系泥岩盖层之下具有多套生储盖及其组合，石炭系下部不整合是塔里木盆地构造演化和油气成藏等方面最重大的事件。构造演化的特殊性和丰富多采的油藏类型造就塔中地区石炭系泥岩盖层之下区域分布广泛的复合油藏体系。对塔中地区油气勘探要整体考虑，运用三维立体交叉式综合勘探。
It is proved that Tazhong region is basically provided
with necessary factors responsible for the richness in hydrocarbon after a comprehensive
discussion of regional and petroleum geology condition. The Tazhong Uplift takes its shape
early, and grows steadily in later period. Huge to large structures develop well in Lower
Paleozoic deposition. A series of sources, reservoirs, seals and their compositions are covered
by carboniferous mudstone. The unconformity lies in Lower Carboniferous is the most important
role in the respects of tectonic evolution and generating and being buried by hydrocarbon. The
speciality of tectonic evolution and richness, varied types of oil pool in Tazhong region resulted
in a regional and widespread system of oil pool composition under the seal of Carboniferous
mudstone. Oil and gas exploration in Tazhong region should be approached from a
consideration as a whole, and the synthetic threedimensional alternated exploration is needed
emergently.
