Description

Method and device for projecting oil reservoir attributes on section

Technical Field

The application relates to the technical field of petroleum geological exploration and development, in particular to a projection method and device of oil reservoir attributes on a section.

Background

According to data statistics, in the exploration and production practice of the fault block oil and gas reservoir, most oil reservoirs are greatly influenced by faults, and the faults have important functions on the connectivity, the closure, the trap amplitude and the form of sand bodies in the oil reservoirs, the possibility of forming the reservoirs and the like.

The influence of faults on oil reservoirs tends to be in various aspects, and at present, the faults serve as an important structural form and can serve as a channel for transporting oil and gas and a barrier for blocking the flow of the oil and gas. At present, the research methods for the influence of faults on oil reservoirs mainly comprise two main categories, namely qualitative and quantitative. Qualitative evaluation methods are mainly ALLan and Knipe (Allan, 1989; Knipe, 1992, 1993, 1997) which are often used to quickly determine the juxtaposition of formations above and below the fault, which may form fault-lateral trapped hydrocarbons, in juxtaposition with impermeable formations (with high contents of mudstone, such as shale and mudstone); the juxtaposition of reservoir sandstones with one another may create a leak-off window that facilitates the passage of hydrocarbons through the fracture. The quantitative evaluation methods are mainly mudstone smearing Potential (CSP), mudstone smearing factor (SSF), fault mud Ratio method (SGR) and the like, wherein Bouvier et al (1989) propose the mudstone smearing Potential CSP, the size of which increases with the increase of the thickness of the mudstone layer and the number of strata with high content of mudstone and decreases with the increase of vertical fault distance. Lindsay et al (1993) proposes a mudstone smear factor SSF, the magnitude of which is proportional to the standoff and inversely proportional to the thickness and quantity of mudstone in the formation. The evaluation method takes the influences of mudstone smearing and fault distance change on fault closure into consideration, and is a main method for researching the influences of faults at home and abroad on oil reservoirs at present.

However, the real situation is more complicated, and the existing oil reservoir evaluation methods basically start from the perspective of single well data and homogeneity, but cannot accurately reflect the property heterogeneous change in the oil reservoir, particularly the change near a fracture zone, and have the problems of single evaluation parameter, no consideration of heterogeneity, great deviation and one-sidedness of the evaluation result, and serious limitation of the improvement of the evaluation accuracy and the reliability of the result of the influence of the fault on the oil reservoir.
