Abstract

The invention provides a method and device for determining design parameters of a while-drilling electromagnetic wave resistivity logging instrument. The method comprises the steps that logging response under different instrument parameters is analyzed when the while-drilling electromagnetic wave resistivity logging instrument considers the forward looking detection range, and thus logging response analysis results under the different instrument parameters are obtained; logging response of different instrument structures is analyzed when the while-drilling electromagnetic wave resistivity logging instrument considers the forward looking detection range, and thus logging response analysis results of the different instrument structures are obtained; and according to the logging response analysis results under the different instrument parameters and the logging response analysis results of the different instrument structures, the design parameters of the while-drilling electromagnetic wave resistivity logging instrument are determined, and the design parameters comprise the range of the instrument parameters and the adopted instrument structures. According to the method and device, the design parameters of the while-drilling electromagnetic wave resistivity logging instrument can be determined, and thus the forward looking detection ability of the while-drilling electromagnetic wave resistivity logging instrument is improved.

Description

technical field [0001] The invention relates to near-drill resistivity and while-drilling electromagnetic wave resistivity logging technologies in the field of petroleum development, in particular to a method and device for determining design parameters of a while-drilling electromagnetic wave resistivity logging instrument. Background technique [0002] At present, the domestic LWD system mainly meets the logging needs of conventional horizontal wells, lacks the forward-looking logging function, and the reservoir drilling rate of horizontal wells is low, and the development effect cannot reach the expected goal. [0003] Due to the shallow detection depth of the near-bit resistivity logging technology, azimuth electromagnetic wave logging while drilling is currently being studied as the main direction of forward-looking resistivity logging. The conventional electromagnetic wave resistivity logging tool while drilling cannot measure the azimuthal formation resistivity, and c...
