| Zusammenfassung: | The embodiment of the invention provides a sweet spot area determination method and device. The method comprises the steps that the well logging data of a target area are acquired, wherein the well logging data comprise first well logging data and nuclear magnetic resonance well logging data; according to the first well logging data and the nuclear magnetic resonance well logging data, a first sweet spot pointing curve is established; a second sweet spot pointing curve is established according to the first sweet spot pointing curve and the first well logging data; according to the first well logging data, the second sweet spot pointing curve is used to identify sweet spots; and earthquake inversion is carried out on the target area with the sweet spots to determine the distribution plane of a sweet spot area in the target area. According to the invention, the nuclear magnetic resonance data, the first well logging data and earthquake inversion are combined; the sweet spots are identified through the second sw |
