Embodiment 1

[0016] Such as figure 1 A three-dimensional geological modeling method for reservoirs is shown. In a certain exploration and development block, the following technical steps are implemented according to geological conditions and research target requirements: (a) implement three-dimensional seismic exploration on the surface; (b) select a Design the well structure of the exploratory well at N positions representing significance, and carry out the construction operations of N exploratory wells; among them, the following technical steps are implemented for each exploratory well (where N is a positive integer greater than or equal to 5); (c) the whole well The cuttings logging work is carried out once every 2m, and it is estimated that the sand is once every 1m in the reservoir section; (d) Resistivity logging, sonic logging, spontaneous potential logging, natural gamma logging, neutron compensation Logging, density logging, and caliper logging, to obtain the above-mentioned loggi...

Abstract

The invention discloses a reservoir three-dimensional geological modeling method. Through performing three-dimensional seismic prospecting on the land surface, N exploratory wells with representing meaning in one block are selected. dense sand bailing, routine logging, imaging logging, VSP logging and cross-well seismic earthquake on each exploratory well, integral and comprehensive logging interpreting is performed. Then through performing well wall centering on the reservoir which is obtained through logging interpreting, scanning electron microscope observation, porosity determining and rock strain experiment are performed on an acquired rock core. Furthermore logging interpreting is performed. Finally modeling software is utilized for establishing a reservoir three-dimensional geological model, thereby realizing comprehensive and accurate establishing of a reservoir three-dimensional geological model, and realizing a purpose of high convenience in performing detailed searching on the basic geological information of the reservoir.

Description

technical field [0001] The invention relates to the field of geological exploration and development, in particular to a three-dimensional geological modeling method for reservoirs. Background technique [0002] Geological modeling of reservoirs has always been one of the important links in the exploration and development of oil and gas fields. From the perspective of oil and gas field development, the study of reservoir geological model is an important means to enhance oil and gas recovery and improve development methods. The established geological model can provide geological personnel with a lot of information. The first is the three-dimensional visualization of reservoir geology. We can see the three-dimensional spatial distribution and changes of reservoir geology, and we can also make two-dimensional pictures such as structural maps, isopach maps, and lithofacies distribution maps. Secondly, it provides geological personnel with a set of organically integrated data bo...
