| Popis: | The objective of this study is to establish the thermal regimes and heat flow distribution in the Malay, Sarawak and Sabah sedimentary basins. This will assist in improving knowledge on the geology and hydrocarbon resources potential of these basins. A geothermal gradient database was created from well and temperature data of over 400 exploration and production wells. Measured thermal conductivity data from previous work were revised, while recently measured thermal conductivities of post-1980 wells were incorporated into the thermal conductivity database. A thermal conductivity table of average measured thermal conductivities corresponding with the different groups/cycles were created for each basin. Geothermics maps, consisting of geothermal gradient, thermal conductivity and heat flow, were produced. Results reveal a decreasing heat flow trend from west to east, with the Malay basin showing the highest heat flow and the lowest in the Sabah basin. Abstrak: Objektif utama projek ini adalah untuk menubuhkan satu kajian rejim terma dan taburan aliran haba di lembangan sedimen Melayu, Sarawak dan Sabah. lni akan meningkatkan pengetahuan kita dalam geologi rantau dan keupayaan punca hidrokarbon. Satu pengkalan data kecerunan suhu telah dibina daripada data-data telaga dan suhu daripada lebih 400 telaga-telaga eksplorasi dan produksi. Data-data ukuran keberkonduksian terma daripada keIja-keIja terdahulu telah dianalisis semula dan dikemaskinikan dengan telaga-telaga terkini (selepas 1980) untuk meghasilkan satu pengkalan data keberkonduksian terma. Peta-peta geoterma yang terdiri daripada peta kecerunan suhu, peta keberkonduksian terma dan peta aliran haba, telah dihasilkan. Keputusan menunjukkan trend aliran haba menurun dari barat ke timur dengan lembangan Melayu menunjukkan aliran haba yang tertinggi, sementara lembangan Sabah menunjukkan aliran haba yang terendah. |
