Paraphrasing the term:
oil reservoir: it is meant that the oil has a substantial accumulation of the same pressure system in a single trap. If only oil is collected in one trap, it is called a reservoir; only natural gas, called a gas reservoir, accumulates.
Oil source fracture: connecting the source rock with the overlying target layer, and breaking the source rock and the overlying target layer during the oil and gas accumulation period. The oil-gas reservoir distribution is related to the development degree of a reservoir near the oil source fracture and the difference of oil and gas conducting capacity of different oil source fracture positions.
In the prior art, when the well position deployment is carried out on the oil reservoir to be developed, the well position deployment area of the oil reservoir to be developed is determined according to the experience of developers and the oil source fracture condition of the oil reservoir to be developed, but the drilling effect difference of different areas in the same fracture zone is large, and the method has the advantages of low well position deployment accuracy and high risk.
