依据钻井、MT测深、地震剖面资料对沧东断裂山岭子东段地质构造进行了研究,认为该段沧东断裂断面形态呈“阶形”,自沧县隆起至北塘凹陷由高、中、低三个台阶组成断阶构造。中生代白垩纪末期,在南东-北西向压扭应力作用下形成褶皱及逆断层,新生代古近纪反转为正断层,断阶带内发育北东及北北西向共轭剪切断层,它们是沟通不同热储层的重要通道。
依據鑽井、MT測深、地震剖麵資料對滄東斷裂山嶺子東段地質構造進行瞭研究,認為該段滄東斷裂斷麵形態呈“階形”,自滄縣隆起至北塘凹陷由高、中、低三箇檯階組成斷階構造。中生代白堊紀末期,在南東-北西嚮壓扭應力作用下形成褶皺及逆斷層,新生代古近紀反轉為正斷層,斷階帶內髮育北東及北北西嚮共軛剪切斷層,它們是溝通不同熱儲層的重要通道。

Based on the drilling data, combining with MT sounding, seismic profile data, the geological structure of Sanlingzi Eastern Part oF Chandong Fault was studied. It is suggested that the fault plane of this section shows“ladder type”, and composed of three steps:high, middle and low fault terrace structure from Cangxian uplift to Beitang sag. In end of Mesozoic cretaceous period, the fold and thrust fault formed under the action of NW direc-tion torsional stress. And during Cenozoic paleogene age turned into normal fault.The fault terrace zone devel-oped NE and NNW conjugate shear faults, and they are important communication channels of different thermal reservoir in this area.
