The paper made a re-recognition of Jurassic oils in Sichuan in terms of the four aspects, such as resource potential, reservoir types, fractured reservoirs and techniques of exploration and development. The paper has drawn the following conclusions: 1) the Jurassic oil resource in Sichuan may be much more than the presently discovered amount of 1. 0～ 1. 1 billion tons; 2) the Jurassic oil resource is a special large-area and non-conventional compact oil accumulation that has no clear trap boundaries, no clear edge-water, bottom-water and oil-water boundaries like a “water-free reservoir”; 3) Jurassic reservoirs can not be simply defined as "fractured type" because various pores contribute significantly to both the reserves and long-term low but stable production though fractures are the prerequisite for a high output at the testing or production beginning; and 4) this kind of non-conventional compact oils in the central-northern Sichuan Province.
