摘要
盐城天然气藏的发现经历曲折 ,给人启示。从天然气藏的基本地化特征、天然气及其源岩类型、天然气成熟度等分析 ,盐城天然气藏为“古生新储”型晚期成藏的天然气藏。该气藏发现的意义在于为苏北地区“古生新储”、“古生中储”型天然气藏的勘探提供了地质模型 ,也为扬子中古生界海相地层的勘探提供了借鉴。
The discovery of Yancheng natural gas accumulation is tortuous and enlightening. The analysis on the basic geochemical characteristics of natural gas accumulation, the types of natural gas and its source rocks, and the maturity of natural gas shows that Yancheng natural gas accumulation is a type of “Paleozoic generating and Cenozoic reserving” late accumulating one. This discovery provides a geologic model for the exploration of “Paleozoic generating and Cenozoic reserving” and “Paleozoic generating and Mesozoic reserving” typed natural gas accumulation in North Jiangsu area. It can also be used for reference in the exploration of the Meso-Paleozoic marine strata in Yangtze area.
