| 摘 要： | 通过对济阳坳陷7个油田60多个油气藏几十条断层的研究,提出泥岩涂抹长度计算方法,对断层封闭性的计算公式进行修正,并用新修正的公式对营子街地区断层封闭性进行研究.结果表明:济阳坳陷断层封闭的泥岩涂抹界限值是5;纵向上沙三上亚段Ⅲ砂组中下部、IV砂组、V砂组断层封闭性好,平面上街202、街204、街201等井区断层封闭性好,与油气富集层位非常吻合. |

| Abstract: | By studying tens of faults in over sixty hydrocarbon reservoirs of seven oilfields in Jiyang depression, a calculation method of shale smear length was presented, the calculation formula for fault sealing was modified and then the fault sealing in Yingzijie area was analyzed. The results show that the effective mudstone thickness in the ranges of shale smear length must be determined in order to reflect the fault sealing correctly. The boundary value of the fault sealing is 5 in Jiyang depression. The fault sealing in Yingzijie area is good in the middle-lower part of the third sand bodies, the fourth and the fifth sand bodies of the upper Es_3 formation, and so is the area near the well Jie 202,well Jie 204 and well Jie 201, which agree well with oil and gas rich layer. |
| Keywords: | fault sealing shale smear length Jiyang depression Yingzijie area |
