  Using archival spectral-imaging data with a total exposure of $\sim144$ ks
obtained by {\it Chandra}, 43 X-ray sources are detected within the half-light
radius of globular cluster M62 (NGC6266). Based on the X-ray colour-luminosity
diagram or the positional coincidences with known sources, we have classified
these sources into different groups of compact binaries including cataclysmic
variable (CV), quiescent low mass X-ray binary (qLMXB), millisecond pulsar
(MSP) and black hole (BH). Candidates of the X-ray counterparts of 12 CVs, 4
qLMXBs, 2 MSPs and 1 BH are identified in our analysis. The data used in our
analysis consist of two frames separated by 12 years, which enable us to search
for the long-term variability as well as the short-term X-ray flux variability
within each observation window. Evidence for the short-term variability and
long-term variability have been found in 7 and 12 sources respectively. For a
number of bright sources with X-ray luminosities $L_{x}\gtrsim 10^{32}$~erg/s,
we have characterized their spectral properties in further details. By
comparing the X-ray population in M62 with those in several other prototypical
globular clusters, we found the proportion of bright sources is larger in M62
which can possibly be a result of their active dynamical formation processes.
