Embodiment 1

[0028] Such as figure 1 and figure 2 The injection-production well pattern arrangement method of the irregular triangular oil reservoir shown includes the following steps: (a) Outline the oil reservoir into a triangular structure according to the shape of the outer shape of the oil reservoir, and mark the vertices and midpoints of each side of the triangle , and the center of gravity; (b) arrange the water injection well 1 at each vertex of the triangle, the midpoint of each side, and the center of gravity; (c) on the connection line between the center of gravity and each vertex of the triangle, the connection line between the center of gravity and the midpoint of each side Arrange the production well 2. It also includes arranging auxiliary water injection wells 3 between each vertex of the triangle and the midpoint of each side. Set the wellbore trajectory of the production well on the line between the center of gravity of the triangle and each vertex as a vertical well, a...

Abstract

The invention discloses an injection-production well pattern arrangement method for a scalene-triangle-shaped oil deposit. The injection-production well pattern arrangement method includes (a), drawing the outline of the oil deposit as a triangle structure according to the external contour of the oil deposit, and marking each peak, each side midpoint and the center of gravity of the triangle; (b), arranging water injection wells at the peaks, the side midpoints and the center of gravity of the triangle; (c), arranging production wells at the connection lines between the center of gravity and the peaks of the triangle as well as the connection lines between the center of gravity and the side midpoints of the triangle. By the injection-production well pattern arrangement method for the scalene-triangle-shaped oil deposit, the problem of low exploitation efficiency easily caused by injection-production well pattern arrangement of triangular oil deposits in the prior art is solved, and the objectives of improving recovery efficiency of the triangular oil deposits and reducing water content of producing liquid are achieved.

Description

technical field [0001] The invention relates to the field of well patterns in oil and gas fields, in particular to a method for arranging injection-production well patterns in irregular triangular oil reservoirs. Background technique [0002] Well pattern refers to the distribution of oil, gas and water injection wells during the development of oil and gas fields. It is an important link in the development plan of oil and gas reservoirs, which is related to the efficiency of oil field development, ultimate recovery rate and economic benefits of oil field development. In the prior art, for the layout of the well pattern in the reservoir, the total geological reserves of the reservoir are divided by the controlled reserves of a single well obtained from the conventional well test to obtain the required number of production wells, and then use this as the basis. According to the basis, a row of production wells corresponds to a row of water injection wells, so that a grid-like ...
