摘要

台灣西南部屏東平原及附近鑽井屢次發現天然氣，而且有多處泥火山噴出天然氣，經分析多為熱成熟氣，顯示當地有氣源。根據近海海域震測線及新增之陸上二維震測資料解釋，得知由小琉球往北進入陸上的鳳山背斜為一泥岩貫入體構造帶，推斷鳳山1號井可能鑽入泥岩貫入中心裡面，鑽深1,597公尺以下時遇高壓現象，雖頻遇氣切，卻無生產價值。建議以圍繞泥岩貫入體構造周圍的上傾地層為目標，再鑽一口新井，了解地下地質及岩性等，驗證高屏泥火山地區之儲油氣潛能。

There are numerous mud volcanoes found in the southwestern Taiwan. The erupted gas from the mud volcanoes is thermally mature. The gas cuts from several wells drilled in the Ping-tung plain also showed thermal maturity indicating a rich hydrocarbon potential in the area. Seismic data from the area showed a belt of mud dirpir structure extending northward from Liuchiu-hsu to Fungshan anticline. Well FS-1 was drilled into the mud core with high pore pressure below 1,597 m. Although there were abundant gas cuts from Well FS-1, well test results proved uneconomical.We suggest a new well be drilled into the up-dip sand bodies surrounding the mud dirpir to evaluate the natural gas potential in the mud volcano area.
