Abstract

After more than 50 years of exploration, Liaohe Exploration Area has entered the stage of high maturity exploration as a whole. How to obtain new exploration discoveries continuously in the Old Area is the primary problem to solve the contradiction of resource substitution. During the 13th Five-year Plan, based on the reconstruction of old data and by taking the building of a new oil-gas reservoir model as the core, the reconstruction of old data as the basis and the new technology of “wide azimuth, wide band, high density” as the means, we have carried out “overall understanding, overall evaluation and overall deployment” for each depression of Liaohe Exploration Area, found five exploration fields, namely conglomerate reservoir in steep slope zone, deep overpressure igneous reservoir, shale reservoir in the central depression, residual Mesozoic buried hill reservoir and middle and shallow complex fault block reservoir, and put one 100 million-tonnage reserve zone and eight 10 million-tonnage reserve zones in place. The exploration practice during the 13th Five-year Plan shows that there is still great potential for exploration in the old areas rich in oil and gas by freeing the minds, proceeding with confidence, breaking through theory and optimizing technology.

Key words： reconstruction of geological data; reconstruction of oil and gas pool-forming model; volcanic shale oil; oil and gas-rich depression; Liaohe exploration area
