| 中文摘要 | A由田為一高壓之揮發性油田,先後鑽探A1與A2兩口井,累計生產由13,857公秉及氣1,003萬立方公尺,A1井已廢井,A2井目前亦已停產。為了解此油田再開發之可能性,採用成份模式進行生產動態模擬。 模擬結果顯示:由原始資料所建立之模擬模式無法 解釋A2井出水現象。為了改善調諧結果,本研究進行兩種嘗試:首先以不大幅的原始埋藏量為原則,提高油水界面,並將水層之滲透率由10md增加至500md;第二個方法為局部修變孔隙率降低原始埋藏量,以加速地層水入侵速度,調整過程中部份孔隙率需設定為1%。經調整後,模擬結果與現場量測資料尚稱吻合,但由於只有兩個控制點,地質模式之不確定性甚高,使得模擬模式之代表性降低,可能肯定的是,A油田原始原油埋藏量應比依體積法估算值為小。 |
| 英文摘要 | The “A” oil field is a volatile oil reservoir with abnormal pressure. The cumulated oil and gas production are 13875 KL and 10,030 MScm respectively. There are tow wells, A1 and A2, which had been drilled in this area. A1 well was abandoned and A2 is in consideration of abandonment. To evaluate this field, a compositional simulation model was built. Our results show that the original setting cannot satisfy the water cut observed in A2. To improve the history match, two routs are proposed. First, the permeability was adjusted from 10md to 500md in the qualifier. Secondly, the porosity distribution was set to 1%. Both two ways show better match than original one. But the representation of model was not high since there were high uncertainties in geology model. We can concluded that the OOIP in this area should be smaller than the estimated result by volumetric method. |
