Description

Projection method and device of oil reservoir attribute 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 properties on a section.

Background

According to data statistics, in the exploration and production practice of the fault block oil and gas reservoirs, most of oil reservoirs are greatly influenced by faults, and the faults play an important role in connectivity, closure, trap amplitude and form of sand bodies in the oil reservoirs, whether the reservoirs can be formed or not and the like.

The influence of faults on oil reservoirs tends to be multiple, and at present, the faults serve as an important structural form, and can serve as a channel for transporting oil and gas and also can serve as a barrier for blocking the flow of the oil and gas. At present, the research methods of the influences of faults on oil reservoirs mainly comprise qualitative and quantitative methods. Qualitative evaluation methods are mainly ALLan and Knipe (Allan, 1989; knipe,1992, 1993, 1997), which are often used to rapidly judge the juxtaposition of formations above and below a fault, where juxtaposition of reservoirs with non-permeable formations (with high contents of mudstones, such as shale and mudstone) may form a fault-side seal; the reservoir sandstones are juxtaposed with each other to form a leakage window, which is beneficial for oil and gas to pass through the fault. The quantitative evaluation methods are mainly mudstone smear potential (Clay Smear Potential, CSP), mudstone smear factor (Shale Smear Factor, SSF), fault mud ratio method (Shale Gouge Ratio, SGR), etc. wherein Bouvier et al (1989) proposes a mudstone smear potential CSP, the size of which increases with increasing mudstone layer thickness and increasing number of layers with high content of mudstone, but decreases with increasing vertical fault distance. Lindsay et al (1993) proposed a mudstone smear factor SSF, the size of which is proportional to the break distance and inversely proportional to the thickness and quantity of mudstones in the formation. The type evaluation method considers the influences of mudstone smearing and break distance change on fault sealing, and is a main method for researching the influences of faults at home and abroad on oil reservoirs at present.

However, the actual situation is more complex, and the current oil reservoir evaluation method basically cannot accurately reflect the heterogeneous change of the property in the oil reservoir from the angles of single well data and homogeneity, particularly the change near a fracture zone, has single evaluation parameters, does not consider the heterogeneity, has the problems of great deviation and one-sided performance of the evaluation result, and severely restricts the improvement of the fault on the evaluation accuracy of the oil reservoir and the reliability of the result.
