中文摘要 | 鐵砧山氣田(TCS)為本省最大之氣田,陸續鑽至39號井共計有31口成功井,其主 要生產層為鐵通1A層(TT-1A),曾經多次應用油氣層電腦模擬來評估其蘊藏量及擬訂 其生產方案。但油氣層電腦模擬需要調整之參數甚多,故油氣層電腦模擬之準確性在於 地質資料及油氣層描述之正確與否。而每次模擬歷史調諧所花費之間時頗長,且其準確 性往往不如預期的好。其主要原因為油氣層特性分析不夠詳細,不能詳細描述油氣層之 細部變化以提供電腦模擬之充分資料所致。因此本所引進油氣層特性分析軟體(RC��), 整合震測資料、地質資料及電測資料以地質統計方法計算出其特性之細部分佈,以增加 未來油氣層電腦模擬之精確性。 光由井控制點孔隙率分析求得之孔隙率分佈,因缺乏其他資料之佐證,可能會使孔 隙率值估算產生誤差。若能整合岩相(分類變數)與井孔隙率(連續變數)資料將有助 於預測較準確之孔隙率細部分佈。本研究完成鐵砧山氣田三維孔隙率可供未來該氣田油 氣層模擬時之應用。 |
英文摘要 | TCS Field is the biggest gas field in Taiwan. The main production zone is the TT-1A zone in Ta- Lu Formation. Currently, there are several evaluations of the reserve using reservoir simulators. To match the current history, it requires a lot of adjustments of a huge number of parameters. The accuracy of the reservoir simulation is not good as expected due to that the description of reservoir is inaduquate. Having detailed description of reservoir properties is essential to obtain a accruate simulation. Therefore, the Exploration & Development Research Institute (DERI) ppurchased the reservoir characterization software (RC �� ), which gives a more detailed reservoir dexcription and shall enhance the reservoir simulation in the future by using the geo-statistics method with integration of the seismic, geologic and logging information. The results indicate that the distribution of porosity can be overstimated by the well control only. The integration of the facies (Categorical variable) and porosity (Continuous variable) can help to improve the description of the porosity distribution and reduce the uncertainty. The 3D distribution model of porosity has been established based upon the porosity at wells as well as the facies distribution from logs. This is to be used for infill drilling or reservoir simulation in the future. |
