Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0021] In the actual exploration and development process of oil and gas reservoirs, the quality of reservoirs depends on the development degree of reservoir pores and water saturation. Generally, sandstone reservoirs with high porosity and low water saturation, that is, high hydrocarbon-containing pore reservoirs, are defined as high-quality reservoirs and are the targets with the greatest potential for oil and gas development. In order to realize the fine description and characterization of high hydrocarbon-containing pore reservoirs, the embodiment of the present in...

Abstract

The invention discloses a method and device for detecting hydrocarbon-containing pores in a reservoir. The method comprises the steps that the longitudinal wave impedance data and shear wave impedancedata of a work area are acquired; a hydrocarbon-containing pore factor of the reservoir is constructed according to the longitudinal wave impedance data and the shear wave impedance data; and hydrocarbon-bearing pore detection of the reservoir is carried out according to the hydrocarbon-containing pore factor of the reservoir. According to the invention, the multiplicity and limitation of a conventional reservoir prediction method can be overcome, and the accuracy of reservoir prediction is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum geophysical exploration, in particular to a method and a device for detecting hydrocarbon-containing pores in reservoirs. Background technique [0002] In the process of petroleum exploration and development, reservoir hydrocarbon-bearing pores are a very important parameter, which determines the exploration potential and oil and gas abundance of the reservoir. In the process of reservoir prediction, the identification of reservoirs with well-developed pores and high hydrocarbon saturation is a core content and the ultimate goal of exploration and development. [0003] The difficulty of reservoir hydrocarbon-bearing pore prediction is to describe reservoir porosity and water saturation at the same time. In the existing reservoir prediction technology, one attribute can only characterize one aspect of the reservoir, such as reservoir porosity or reservoir fluid type. Therefore, in order to achi...
