摘要:

渤海海域平均大地热流值为(60.9±8.7)mW/m2,其中石臼坨凸起、沙磊田凸起和渤南凸起热流值高达70~80mW/m2,渤中凹陷、黄河口凹陷和秦南凸起次之,其热流值也达到65~75mW/m2,辽东湾、庙西、莱州湾、歧口、沙南、埕北等地区热流值较低,基本上都在65mW/m2以下.渤海海域平均地温梯度为30.8℃/km,但各构造单元存在差异,其中沙磊田凸起、渤中、渤南、石臼坨等地区地温梯度明显较高,一般为32~42℃/km之间;凹陷区地温梯度低,一般为22~32℃/km之间.渤海海域地温场的分布与渤海海域的构造形态相似,大体反映了北北东走向的郯庐断裂构造型态.

Abstract:

The average geothermal flow in the Bohai Sea waters is (60.9±8.7)mW/m2.It is up to 70~80 mW/m2 in the Shijiutuo,Shaleitian and Bonan uplifts,65-75 mW/m2 in the Bozhong sag,the Huanghekou sag and the Qinnan uplift,while lower than 65 mW/m2 in the Liaodong bay,Miaoxi,the Laizhou bay,Qikou,Sha'nan and Chengbei.The geothermal gradient varies in different structural units of the Bohai Sea waters and averages at 30.8℃/km.Higher geothermal gradient 32-42℃/km,is tested in the Shaleitian uplift,Bozhong,the Laizhou bay,Qikou,Sha'nan and Chengbei.In contrast,it is low in the sags,22-32℃/km on average.The distribution of geothermal field coincides with the structural configuration in the Bohai Sea waters,roughly reflecting the structural form of the NNE-trending Tan-Lu Fault.

Key words: geothermal flow, geothermal gradient, geothermal field, Bohai Sea waters
