Abstract: The competitive transfer of oil and gas exploration rights is an important way for oil and gas enterprises to obtain exploration rights blocks, and the evaluation process is characterized by limited data, low level of study and short period. The difficulty in scientifically formulating bidding plans lies in how to comprehensively, rapidly, and accurately evaluate the exploration potential, resource scale, and development economy of transfer blocks in a short term. However, there is a lack of the systematic evaluation method at present. The early study results have shown that the key to the rapid evaluation of competitive transfer blocks includes the optimal selection of rational evaluation parameters and the establishment of parameter standards, and the core of the rapid evaluation of transfer blocks is the comprehensive and quantitative evaluation results. Based on data status and bidding policy of the transfer blocks, nine types of evaluation factors, including data conditions, geological conditions (exploration potential in the region, source rock, reservoir, preservation, trap, and hydrocarbon accumulation assemblage), reliability of resource amount and engineering technology, as well as 18 evaluation parameters and their assignment standards have been proposed, and a rapid evaluation system for competitive transfer blocks has been established. In addition, the petroleum exploration successful probability method has been proposed for comprehensive and quantitative evaluation of exploration potential, exploration risk and engineering technology, as well as the discounted cash flow method and analogy method for economic evaluation, which provide basis for the formulation of bidding plans of transfer blocks. The above method has been applied in some transferred blocks, obtaining bidding plans basically consistent with the actual bidding situation.
