An analysis of salt structure and accumulation in Kenli 11 district of Laizhou Bay Sag

Kenli 11 district in the Laizhou Bay first revealed salt deposition system and related structures in the Bohai Sea. Based on the latest drilling data, the regional tectonic stress analysis, and seismic reflection characteristics, the study shows that salt structures in Kenli 11 district is a salt pillow, in which the thick-ness of salt in the north part is larger than that of the south. The reservoir characteristics are nearsource and short distance migration, which related to salt tectonic activity. The salt geothermal fluid around the salt is important for improving the quality of the oil. The upper salt formation is an important target of ex-ploration.
