Md1 dolomite is mostly 30–100 μm in size but can reach more than 100 μm (Fig. 3 A). The dolomite crystals show planar-s textures and linear or point contacts (Fig. 3 A). Pyrites are commonly distributed in the intercrystalline pores (Fig. 3 A). Md1 dolomite is the most widely distributed Lower Paleozoic matrix dolomite in the study area.

Prediction of reservoir quality in carbonates via porosity spectrum
Open fractured zones are recognized as dark sinusoidal waves, and the vuggy dolomites can be recognized by the dark spots on the image logs. However, the fractured and vuggy dolomites are only occasionally detected, and most of the dolomite reservoirs in Ma 5 contain only intercrystalline pores, which are difficult to be recognized by image logs.

Intuitive Understanding of Sine Waves
sin(2x) is a wave that moves twice as fast; sin(0.5x) is a wave that moves twice as slow; So, we use sin(n*x) to get a sine wave cycling as fast as we need. Often, the phrase "sine wave" is referencing the general shape and not a specific …

1.1: Sine Wave
The height of the wave at any location and time, measured from the middle, or equilibrium position is the displacement. The maximum displacement is called the amplitude. As a first approximation, water waves, electromagnetic waves and many other kinds of waves can be modeled by the mathematical functions sine or cosine or some combination of them.

Sinusoidal Waves
An important aspect of sinusoidal waves is that they are periodic in both space and time.The displacement (D(x,t) ) of a particle in the medium depends on both the particle's position (x ) and the time (t) when you observe it. In Figure 7.2.2, we show a graphical representation of a sinusoidal wave in space and time.The period of the wave, is related to the frequency of the …

However, in practice, the signals processed are often prefiltered and, in lower voltage distribution systems in particular, the waveforms often very quickly attain a nominally sinusoidal form. Historically, algorithms developed for use in applications where the signals processed are nominally sinusoidal were the first to emerge [1, 2].

Sinusoidal Signal
A wave that cannot be describe as a function of sine wave is known as a non-sinusoidal wave. It is a non-continuous signal. What are some real-life examples of a sinusoidal signal? In real-life we can represent water waves and sound waves as sinusoidal signal since they are periodic and continuous signals.
