Abstract

Abstract: In order to make full use of coalbed methane resources and highlight shallower horizons of Fuxin coalbed, this paper rechecks and explains the well log data of 29 wells in Baoriwendu and vicinity, confirming 14 wells with coalbeds in which 8 wells are newly explained, 6 wells are re-verified. These allow to determination of the coabed distribution, thermal evolution history and petrophysical property as well as seals conditions in Lujiabao sag. Meanwhile, this paper presents the evaluation of the favorable areas for coalbed methane exploration and point of view about how to explore it according to the composite geologic analyses.

Key words: Kailu basin, coalbed methane, Cretaceous, thermal history
