【Abstract】 Oil and gas exploration began very early in the Bayindulan sag of Erlian basin, but so far, no oil or gas was discovered there. The source rocks of the sag are good, but the large structureal traps are not matched with the favourable reservoir belt, so structural oil reservoirs have never been found within more than 20 years. Fortunately, from 2001, people put their focus on the prospecting for subtle traps, represented by using inversion softwares, such as STRATA, ISIS, JASON, carefully identifying the K 1Ba lithologic body on the BaⅡ structure, building the model of structure lithological reservoirs. After these, 5 exploratory wells were drilled, all of them produced commercial oil, and then the Baolige oil field with OOIP more than 10×10 6t was found, which has a production capacity of 7.68×10 4t per year.更多还原
