Abstract

The embodiment of the invention provides a method and equipment for detecting an oil and gas reservoir by a compact oil and gas reservoir fluid factor. The method comprises the following steps: constructing a matrix modulus prediction model of compact sandstone according to an actual core sample of the compact reservoir and test data; constructing a rock physical model under a dry condition of thecompact reservoir by adopting a cemented sandstone theory according to an actually measured core porosity and an acoustic velocity; carrying out fluid replacement analysis and lame modulus related parameter conversion by adopting a Gassmann equation and combining a prediction result of the dry compact sandstone rock physical model, and carrying out fluid sensitivity analysis on lame modulus related parameters; determining an equivalent fluid factor according to attribute parameters of fluid replacement calculation in combination with actual drilling and logging data; acquiring an elastic parameter of a target layer by adopting a seismic inversion method, and calculating a seismic fluid factor data volume in combination with logging information; and carrying out seismic fluid detection analysis according to the newly constructed seismic fluid factor, and predicting distribution of the seismic oil and gas reservoir.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unconventional oil and gas exploration, and in particular to a method and equipment for detecting fluid factors in tight oil and gas reservoirs. Background technique [0002] Due to the complex formation mechanism and distribution rules of tight oil and gas reservoirs, the difficulty of exploration, high technical requirements, and the characteristics of high difficulty and high risk in exploration, the research on the exploration technology of such oil and gas reservoirs has always been the research and exploration of oil and gas exploration experts at home and abroad. important content.
