Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0030] The broken bead body oil reservoir of the present invention may be a kind of carbonate rock karst fracture-cavity oil reservoir. In the broken bead reservoir, the broken bead can be used as storage space for oil and gas. The inventor discovered through creative work that the distribution of oil and gas is controlled by oil source faults and the reservoir space of bead bodies (fracture-cavity bodies connected with oil source faults), and the scale of oil reservoirs and the height of oil columns are only controlled by the shape and development degree of bead bodi...

Abstract

The invention relates to an information recommendation method and device, which belongs to the technical field of electronic information. The method comprises the steps that application information related to payment is acquired; the payment reference information of a number of payment accounts of a user is extracted from the application information; and the payment reference information of a number of payment accounts is analyzed to determine a target payment account, and the target payment account is recommend to the user, so that the user uses the target payment account for payment. According to the method and the device, target payment accounts are recommended to different users in a personalized manner, and the ranking of payment accounts is optimized at the time of payment.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a method and device for determining well points in karst fault bead reservoirs. Background technique [0002] With the improvement of exploration degree, deep fracture-vuggy reservoirs have gradually become one of the main objects of exploration. The main storage space of this type of reservoir is the fracture-cavity body in the karst layer. The oil-water distribution relationship is complex. The reservoir has the characteristics of one cave and one reservoir. It is difficult to explore, and it is difficult to quickly select high-efficiency well points. [0003] The existing technology is to determine the reservoir by analyzing the sedimentary diagenetic process, select the beads with strong reflection on the seismic section, and select the well location according to the principle of oil accumulation at high points. This method has high exploration risk, low succ...
