Shale oil and gas combustion extraction method based on multi-source time sequence remote sensing image

Abstract

The invention relates to a shale oil and gas combustion extraction method based on a multi-source time sequence remote sensing image, and the method employs a large amount of multi-source long-time sequence optical remote sensing data in a combined manner, improves the robustness of remote sensing image detection through higher space and time resolution, greatly improves the monitoring capability of shale oil and gas combustion, and the spatial and temporal distribution of large-area shale oil and gas can be quickly and automatically identified. The method is simple and feasible in execution steps, and the shale oil and gas combustion effect in an extraction area and even the whole world is good. According to the method, long-time and large-space-coverage optical image data are used, an optimized and concise thermal anomaly index is utilized, and accurate extraction of shale oil and gas combustion on a large space scale is achieved. According to the method, a detailed shale oil and gas combustion position which can be updated timely and effectively can be compiled, and meanwhile scientific reference can be provided for shale oil and gas combustion management and evaluation of the potential influence of shale oil and gas combustion on the atmospheric environment in China.

Description

technical field [0001] The invention relates to a method for extracting shale oil and gas combustion based on multi-source time series remote sensing images. It belongs to the technical field of remote sensing geoscience application. [0002] technical background [0003] In the past few decades, with the development of unconventional oil and gas extraction technology (including horizontal or directional drilling, hydraulic fracturing technology), the shale oil and gas production in the United States has increased rapidly, which has attracted widespread attention. Compared with conventional drilling technology, unconventional oil and gas extraction technology has the advantages of easier access (mainly on private land), shorter production time, lower cost and smaller scale, which makes the United States become the world's largest largest oil / gas producer in the world. The shale revolution not only dramatically reduced US oil / gas imports, but also created an engine of econom...

At present, there are low-resolution active fire product data, such as VIIRS Active Fire (375m), MODIS Active fire (1km), VIIRS Night Fire (750m) data, etc. Although these fire product data have high time resolution, However, due to its low resolution, it is far from enough to identify small fires such as shale oil and gas combustion.
