针对大庆油田松辽盆地北部石油、松辽盆地北部深层天然气、复杂断陷盆地——海拉尔、依—舒地堑等外围油气的复杂目标勘探难题，开展了地震采集、处理、解释，测井及钻井等配套技术攻关，形成了岩性油藏高分辨率三维地震勘探技术、深层火山岩三维地震勘探技术、复杂断陷盆地三维地震勘探技术系列，低渗透储层、火山岩储层和复杂断陷储层评价及改造技术系列以及深层火山岩钻井技术，为松辽盆地北部岩性油藏的储量增长、深层火山岩天然气大型气藏发现和复杂断陷盆地勘探突破提供了技术支撑。

Aiming at the 3 types of exploration problem in Daqing Oilfield (oil of shallow and middle layers in the northern Songliao Basin, natural gas of deep layers in the northern of Songliao Basin, oil and gas of complex fault depression—Hailaer Basin and Yi-Shu graben etc., unconventional resources and oversea oil and gas), high-resolution 3D seismic exploration technology of lithologic reservoir, 3D seismic exploration technology of deep volcanic rock, 3D seismic exploration technology of complex fault depression, reservoir evaluation and reformation technology in less permeable reservoirs, volcanic rock and complex fault depression, well drilling technology of volcanic rock deep layers, have been formed through researches on seismic acquisition, processing and interpretation, logging and drilling. The series of technology provided technical supports for incremental reserves of lithologic reservoir in the northern Songliao Basin, discovery of large-scale natural gas reservoir of deep volcanic rock and the exploration breakthrough in complex fault depression.
