Problems solved by technology

[0002] In the accumulation analysis of complex fault block oil and gas reservoirs, if the oil and gas accumulation conditions in the fault block are good, oil and gas exploration can be carried out; if there is no oil and gas accumulation in the fault block, the oil and gas exploration will fail. When considering various oil and gas accumulation conditions, it is necessary to determine the oil and gas migration mode of fault block oil and gas reservoirs. At present, there is no effective means to determine the oil and gas migration mode of fault block oil and gas pools.

Abstract

The invention provides a method and a device for determining the oil-gas migration mode of a fault block oil-gas reservoir. The method comprises the following steps: acquiring fault data, stratum dataand logging data of a target area; analyzing the vertical sealing and lateral sealing of the fault of the target area according to the fault data, the stratum data and the logging data; and determining the oil-gas migration mode of the fault block oil-gas reservoir in the fault according to the vertical sealing analysis result and the lateral sealing analysis result of the fault. According to themethod, the oil-gas migration mode of the fault block oil-gas reservoir can be accurately determined.

Description

technical field [0001] The invention relates to the field of petroleum geological exploration and development, in particular to a method and device for determining the oil and gas migration mode of fault block oil and gas reservoirs. Background technique [0002] In the accumulation analysis of complex fault block oil and gas reservoirs, if the oil and gas accumulation conditions in the fault block are good, oil and gas exploration can be carried out; if there is no oil and gas accumulation in the fault block, the oil and gas exploration will fail. When considering various oil and gas accumulation conditions, it is necessary to determine the oil and gas migration mode of fault block oil and gas reservoirs. At present, there is no effective means to determine the oil and gas migration mode of fault block oil and gas pools. Contents of the invention [0003] The embodiment of the present invention proposes a method for determining the oil and gas migration mode of fault bloc...
