Problems solved by technology

Seismic attribute method is based on anisotropy theory, including multi-component and anisotropic fracture detection technology, fracture prediction method based on log-constrained wave resistance inversion, nonlinear fracture prediction method, etc. Although these methods can realize fracture well time prediction, but the lack of single well data constraints, and a large dependence on the quality of seismic data, the prediction effect is not very ideal

Abstract

The invention discloses a method and a device for volcanic rock crack quantitative prediction. The method for volcanic rock crack quantitative prediction comprises steps of obtaining drilling well rock core data, imaging well logging data and logging curves, generating single well crack density indication curves according to the drilling well rock core data, imaging logging data and logging curves, establishing an oil reservoir three dimensional geology model, extracting geology attribute reflecting cracks from the oil reservoir three dimensional geology model and extracting earth physics attribute reflecting cracks from earthquake data, performing correlation discrimination and generating a pre-judging result according to the single well crack density indication curve, the geology attribute and earth physics attribute, wherein the pre-judging result comprises some kinds of crack attributes, the crack correlation of which is greater than a preset vale, performing crack distribution simulation in a three dimensional space according to the pre-judging result, calculating the continuous distribution model of the three dimensional space and performing quantitative prediction on the crack between wells. The method and device for volcanic rock crack quantification prediction disclosed by the invention can realize the quantitative prediction of the crack between wells and can quickly and accurately determine the favorable task during the volcanic rock oil reservoir exploration and development.

Description

technical field [0001] The invention relates to the technical field of petroleum geological exploration and development, in particular to a quantitative prediction method and device for volcanic rock fractures. Background technique [0002] The exploration and development of volcanic oil and gas reservoirs has a history of more than 120 years. With the increasing difficulty of oil and gas exploration in sedimentary layers and the continuous discovery of volcanic oil and gas reservoirs, volcanic oil and gas reservoirs have been paid more and more attention. However, volcanic rock reservoirs have the characteristics of rapid changes in lithology and lithofacies, complex storage space and accumulation conditions, and difficult data acquisition and processing. Exploration and development is still a worldwide problem. However, how to distribute and predict fractures in space, as oil and gas storage and migration channels, is an unavoidable problem for petroleum geologists to stud...
