Abstract: In the integrative process of oilfield exploration and development,the comprehensive new technologies are effective strategies to develop of difficult-to-recover reserve with heavy oil,which covers from evaluation study to a large scale upgrade of OOIP and accomplishment of oil deliverability.The new methods include 3D seismic survey and fine geologic explanation,multiple-well logging evaluation,well pattern design combined with horizontal well and vertical well,steam huff and puff and hot water flooding,etc.At last these comprehensive technologies have fulfilled a new OOIP of 1456×104 t and an annual oil production capacity of 13.75×104 t in Mian 120 block of Bamianhe oilfield.
