Abstract:

Complexity and diversity of reef reservoir leads to great difficulties to the reef reservoir prediction.After

recent years research，Huanglong reef reservoir prediction has been made some progress.Study suggest that reef reservoirs

prediction can not simply rely on one method，and must be closely integrated with geological，seismic，logging features，

reefs with the favorable development environment are studied and the seismic attribute analysis，natural gamma，speed，

density，porosity and other methods are used to predict reef reservoir development，make relevant and comprehensive fine

interpretation and recognition and demonstrate the laws of reef development.Results indicate that the Huanglongbing

Changhsingian reefs wear developed in the Huanglongchang and Fujiapo areas with beltlike shape，and extended to the

north Qili area.The prediction method provides an important means to Northeast Sichuan Changhsingian reef exploration and

development plays an important role.
