Abstract

Abstract: The right bank block of the Amu Darya River is located in the northeastern part of the Amu Darya Basin in Central Asia and has abundant gas resources. The sub-salt carbonate rocks of the Middle-Upper Jurassic are the main hydrocarbon enrichment formations. Analysis of the geological characteristics and hydrocarbon accumulation factors of sub-salt large and medium gas fields show that: ① The sub-salt large and medium carbonate gas fields can be divided into three types: gas fields of superimposed inner-platform shoals, gas reservoir groups of ramp reef shoals, and fracture-cavity type gas fields in thrust structures. Pore (vug) type inner-platform shoal reservoirs are developed in the gas fields of superimposed inner-platform shoals. They are vertically superimposed, with development of barrier layers and interlayers, forming multiple sets of gas-water systems. Fracture- pore (vug) type ramp reef shoal reservoirs are developed in the gas reservoir groups of ramp reef shoals. In the plane, this is characterized as “one reservoir in one reef”. Carbonate fracture-cavity reservoirs are developed in fracture-cavity type gas fields in thrust structures with complicated gas-water systems. The closer to the main faults, the higher the charging intensity and the lower the gas-water contact. ② Gas fields of superimposed inner-platform shoals are distributed in evaporate platform–restricted platform–open platform. The scale of this type of gas field was controlled by paleogeomorphology and structural amplitude. The gas reservoir groups of ramp reef shoals were located on upper ramp zones of platform margins, with the gas enrichment degree being closely related to the paleogeomorphic high and to the type of reef-shoal. Fracture-cavity type gas fields are distributed in piedmont thrust structural zones. The development scale of faults in the gas fields is the main controlling factor of high gas production and enrichment. ③ The deep clastic rocks of the Middle-Lower Jurassic form a hydrocarbon accumulation assemblage of self-generation and self-storage, which has the conditions required for the formation of large and medium gas fields. Successive structural traps with less reconstruction in the Himalayan and stratigraphic-lithologic traps in the sag zones are favorable exploration targets.
