Development experimental design method based on main contradiction breakthrough direction of oil deposit development difficulties

Abstract

The invention discloses a development experimental design method based on the main contradiction breakthrough direction of oil deposit development difficulties. The development experimental design method based on the main contradiction breakthrough direction of the oil deposit development difficulties comprise the following steps that S1, early experimental data of the oil deposit are analyzed interms of the target oil deposit; S2, the development difficulties of the target oil deposit are found according to early experimental data analysis; S3, according to the development difficulties of the target oil deposit and the oil deposit seepage mode, a core obtained through a cored well is taken as the represent of distribution of the rock quality of the oil deposit, the seepage mode of fluidin the oil deposit is stimulated in the target oil deposit, the main problems in the oil field regulation stage is described, and the oil field development experiment is designed specifically. According to the development experimental design method based on the main contradiction breakthrough direction of the oil deposit development difficulties, development experiment is specifically designed according to characteristics of the target oil deposit, the unnecessary experimental cost is reduced, and meanwhile the time is more saved, through the results of the development experiment, and the corresponding problems of the oil field is instructed to be solved so that the oil field can be put into production faster, and meanwhile the experiment design reference is provided for adjustment schemein the later period of the oil field.

Description

technical field [0001] The invention relates to the field of oilfield development research, in particular to a development experiment design method based on the breakthrough direction of the main contradiction of the difficulty in oil reservoir development. Background technique [0002] The long geological evolution of oil and gas reservoirs, such as depositional process, diagenesis process and geological tectonic action, makes the physical properties (pore structure, permeability), reservoir lithology and thickness, surface properties, contained fluid properties, interlayers and other properties of the reservoir all different. The presence of uneven variation is reservoir heterogeneity. Oil, gas, water seepage and recovery factors directly affect and reflect the development effect of oil and gas reservoirs, among which reservoir heterogeneity is the main influencing factor. The difficulty of reservoir development mainly comes from two aspects, one is that reservoir fluid m...

Problems solved by technology

In the existing technology, there are early basic experiments of reservoirs, but no development experiments for the adjustment period of reservoir development. With the development of reservoirs, the difficulties in the development of reservoirs will appear. According to the difficulties in the adjustment period of reservoir development, the development experiment design is used to analyze the difficulties in development, and to continuously improve the knowledge and understanding of the above-mentioned reservoirs, so as to make various decisions in oilfield development
