摘要
在准噶尔盆地腹部马桥凸起上的盆参２井、盆４井中，先后发现了异常压力，且顶部封闭层埋深均在４４８５ｍ。顶部封闭层以上为正常压力，封闭层以下为异常超高压力。盆参２井在封闭层上下１３００ｍ的井段中油气具有明显的垂向运移和混源特征，应用“流体封存箱”石油地质新理论研究探讨油气运聚成藏模式，取得了令人信服的效果。同时，还对不同温压带中的烃类相带进行了顶测。
Abnormal pressure was discovered in Well Pencan 2 and Well Pen 4 in Maqiao uplift of the hinterland of Junggar basin. with top sealing bed at a burial of 4 485m under which an abnormally high pressure zone exist. Oil and gas from the interval (3 835￣5 135m) of Well Pencan 2 are featured with vertical migration and mixed sources. New theory on petroleum geology 'fluid kitchen' was successfully used to analyse the model for formation of reservoir.Moreover, facies belt of hydrocarbon in different temperature-pressure zones was predicted.
