方位AVO技术在碳酸盐岩缝洞型储层含流体预测中的研究与应用
The study and application of azimuthal AVO analysis technique for fluid-containing prediction of fractured-vuggy carbonate rocks reservoir
摘要
Abstract
AVO analysis technology is an important means to analyze oil and gas fracture cave reservoir in the Upper Ordovician car-bonate strata of the Halahatang oilfield,Tarim Basin.As previous work in this area by using the conventional processing seismic data for AVO analysis did not consider the effect of azimuthal angle factors,the accordance rate of hydrocarbon detection result was low and could not fully meet the high precision requirement of oilfield exploration and exploitation.Therefore,in this paper,in view of the influ-ence of the anisotropy of fractures on the AVO analysis, the authors carried out the analysis of azimuthal AVO based on analyzing the azimuthal anisotropy of OVT gathers so as to weaken the effect of anisotropy on the AVO oil and gas. Practice shows that the application effect is very obvious in that it can effectively weaken the influence of fractured anisotropic characteristics that affects the results of pre-diction of oil and gas. The prediction accuracy is improved and provides a reliable basis for deploying the efficient well group in the de-veloping block.关键词
