阿姆河右岸断裂特征及油气成藏模式

Right Bank of Amu Darya Fracture Characteristics and Hydrocarbon Accumulation Model

阿姆河右岸区块是阿姆河盆地重要的油气富集区,构造多期次性,断裂复杂多类型。通过研究表明,研究区基底地层以正断裂发育为主,明显控制地层沉积厚度。盐下断裂演变为逆断层,并伴生大量圈闭。盐上地层以走滑断裂为主,既发育有正花状又有负花状构造样式,平面上既有左旋走滑,又有右旋走滑断裂。阿姆河右岸油气成藏模式主要有沿断层成藏模式和同层成藏模式,基于此提出了沿凹陷、顺断层找圈闭的勘探思路。

The right bank of the Amu Darya block is an important oil and gasenrichment area of the Amu Darya basin, tectonic tracture complicatedmultiphase, multi type. Through the study,the study area basement stratato faults, are obviously controlled by the sedimentary thickness. Saltfracture evolution as a reverse fault, accompanied by a large number of traps. Salt formation with strike slip fault,not only developing normalflower makeup and negative flower shaped structure style, plane bothsinistral and dextral strike slip fault. The right bank of the Amu Darya oil and gas reservoir forming model mainly along the fault reservoir modeland the same layer accumulation model, based on this proposed along the exploration thinking, find traps along fault depression.
