Logging while drilling reservoir evaluation method, model establishing method and device, and electronic device

Abstract

The invention relates to a logging while drilling reservoir evaluation method, a model establishing method and device, and an electronic device, and belongs to the technical field of reservoir evaluation. The evaluation method comprises the following steps of obtaining element logging data in a drilling process; calculating a brittleness index, a deposition environment and physical property parameters according to the element logging data; performing normalization processing on the brittleness index and the deposition environment separately; and according to the physical property parameters, apre-established three-parameter reservoir evaluation model and a normalized brittleness index and the deposition environment, obtaining a reservoir evaluation result while drilling. According to themethod, the element logging data in the drilling process are obtained, on such basis, the brittleness index, the deposition environment and the physical property parameters are calculated, then the brittleness index and the deposition environment are subjected to normalization processing, and finally, three parameters (the brittleness index, the deposition environment and the physical property parameters) established in advance are combined with the three-parameter reservoir evaluation model of a reservoir evaluation conclusion for processing, so that the reservoir evaluation result while drilling can be quickly and accurately obtained.

Description

technical field [0001] The application belongs to the technical field of reservoir evaluation, and in particular relates to a logging-while-drilling reservoir evaluation method, a model building method, a device and electronic equipment. Background technique [0002] Mud logging operation is the basic technology in the exploration and development of oil and gas reservoirs. It is the most timely and direct technical means to discover and evaluate oil and gas reservoirs. It has the characteristics of timely and diverse underground information acquisition and quick analysis and interpretation. Information service support. [0003] During the exploration and development of oil and gas reservoirs, geological evaluation of the drilled rock formations is required in a timely manner. Existing reservoir evaluation techniques generally require well logging and mud logging data, and comprehensive analysis and research can be used to obtain reservoir evaluation techniques. There is a t...
