Evaluation method of comprehensive factor of fault sealing in volcanic rock area
摘要
Abstract
Based on geological conditions and fault sealing mechanisms in volcanic rock area, a fault sealing model of com-paction diagenesis was established using the method of normal pressure on fault surface, and a fault sealing model of lithology juxtaposition was established based on density difference of fault surface and fault tightness index. An evaluation method of comprehensive factor of fault sealing in volcanic rock area was then carried out after taking normal pressure on fault surface, fault tightness index, density difference of fault surface and fluid index into consideration. The fault sealing in volcanic rock area of Karamay Oilfield is controlled by the fault level as a whole, namely, the better fault sealing leads to better compre-hensive factor, and higher fault level, and eventually greater oil reservoir scale. The quantitative evaluation results compare well with the actual geological conditions, which suggests the wide applicability of the proposed method.关键词
