1) seal type of fault
2) fault sealing
According to sealing mechanism of strata joining and mudstone smearing, fault sealing ability has been quantitatively projected through computer method.
These two factors lead to fault sealing.
断层封闭大致有两种类型 ,一是岩性封闭型 ,断层上、下盘砂泥岩并置造成封闭 ;二是断面型 ,即泥岩涂抹使断面压差很高而封闭。
3) closed fault
ion: Fracture belt presents different structure character,There are two parts from surrounding rock to fracture belt navel including fractured zone and crack vegetal belt,in the fractured zone there maybe develop mylonitized zone near the fracture plane,and there is much mud.
5) fault seal ability
6) fault sealing
Qualitative judgment of fault sealing by using acoustic logging information
A quantitative evaluation of the fault sealing of Chenbao area in Gaoyou sag is made by applying synthetic fuzzy judgment integrated with shale smear factor method.
