  • The Ma51 reservoir is the main gas reservoir in changging gas fieid. The main fracture types of reservoir are four types: verticai, obiigue, horizontai and braided. Aithough there are iots of fracture types in Ma51 reservoir, the main types that have a great infiuence on the percoiation fiow of the reservoir are two types, i. e., structurai fracture and weathered fracture. The formation stages of fracture in Ma51 reservoir are mainiy three, i. e., (l)Caiedonian stage, in which aii kinds of weathered fractures have been formed;(2)mid-stage of Yanshan movement, which is an important structure-ruptured stage;(3)Late Yanshan stage to eariy Himaiayan stage. In this paper, geoiogicai factors forming fractures are studied and anaiyzed, it is summarized as that, the formation of the weathered fractures is mainiy reiated to the occurrence of the rock strata, but the formation of structurai fracture is reiated to the condition of paiaeo-stress fieid and the mechanics property of rock itseif.

A Discussion on the Fracture Characteristics and Controlling Factors of the Ma51 Reservoir in Changging Gas Field

Abstract: The Ma51 reservoir is the main gas reservoir in changging gas fieid. The main fracture types of reservoir are four types: verticai, obiigue, horizontai and braided. Aithough there are iots of fracture types in Ma51 reservoir, the main types that have a great infiuence on the percoiation fiow of the reservoir are two types, i. e., structurai fracture and weathered fracture. The formation stages of fracture in Ma51 reservoir are mainiy three, i. e., (l)Caiedonian stage, in which aii kinds of weathered fractures have been formed;(2)mid-stage of Yanshan movement, which is an important structure-ruptured stage;(3)Late Yanshan stage to eariy Himaiayan stage. In this paper, geoiogicai factors forming fractures are studied and anaiyzed, it is summarized as that, the formation of the weathered fractures is mainiy reiated to the occurrence of the rock strata, but the formation of structurai fracture is reiated to the condition of paiaeo-stress fieid and the mechanics property of rock itseif.
