Analisis dan pemodelan distribusi tegangan sumur bor injeksi pada proses underground coal gasification

نویسندگان

چکیده

Gasifikasi batubara bawah tanah adalah proses gasifikasi secara in-situ pada lapisan yang jauh di dengan cara melakukan injeksi udara bertekanan melalui sumur bor dan menghasilkan gas bakar produksi. Salah satu permasalahan perlu diperhatikan dalam ini kerusakan konstruksi saat menginjeksikan ke sumur, ketika akan membuat jalur koneksi antara Beberapa faktor dievaluasi tegangan regangan maksimum, distribusi temperatur sekitar lokasi tersebut. Analisis pemodelan geomekanika dilakukan terhadap kondisi memerhatikan kekuatan ketebalan casing, karakteristik batuan, daya lekat penyemenan merupakan pengontrol rusak atau tidaknya Dengan asumsi nilai keamanan ?1,3, horizontal maksimum aman 30 MPa perolehan lubang sebesar 454,07 MPa, minimum 0,476 0,08 m, serta berkisar 272,84-22°C terbesar tengah bor. demikian diizinkan MPa.

Underground Coal Gasification: A Brief Review of Current Status

Coal gasification is a promising option for the future use of coal. Similarly to gasification in industrial reactors, underground coal gasification (UCG) produces syngas, which can be used for power generation or for the production of liquid hydrocarbon fuels and other valuable chemical products. As compared with conventional mining and surface gasification, UCG promises lower capital/operating...
