Abstract

The embodiment of the invention discloses a method, device and system for determining sand body connectivity. The method comprises the steps that laser scans a reservoir outcrop-like body of a targetwork area, and a digital outcrop profile of the reservoir outcrop-like body is obtained; the sand body thickness data are extracted on from the digital outcrop section; and the sand body connectivityof the target work area is determined according to the extracted sand body thickness data and the well logging sand body thickness data. By using the embodiments of the method, device and system for determining the sand body connectivity, the sand body connectivity of the target work area can be determined more accurately.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a method, device and system for determining the connectivity of sand bodies. Background technique [0002] Reservoir sand body connectivity generally refers to the way and degree of vertical and lateral interconnection of genetic unit sand bodies, which is an important factor affecting the development of oil and gas fields. However, due to the complex distribution and strong heterogeneity of sand bodies in underground reservoirs, especially the sand bodies in the direction of rivers, the frequent changes of river channels lead to the cutting and repositioning of sand bodies in each stage, and the connectivity of sand bodies in various channels is very complicated. Connectivity prediction is often difficult. [0003] At present, it is usually obtained by obtaining underground well data, and then relying on well data for interpolation to obtain sand...
