【摘要】:本文从地震储层反演,油气检测的物理基础出发,对目前流行的Gassmann理论、Biot理论和BISQ理论的适用情况进行了推算分析,提出每种理论计算的适用范围与局限;针对现场实践与实际推演可知:(1)Gassmann方程可用于地震数据(100Hz)和测井数据(~10~4Hz)的波速测量中,对于实验室超声波测量数据(~10~6Hz),尽量少用;(2)Biot理论应用范围限于孔隙度大,渗透率的饱和岩石,当岩石中的孔隙流体发生不均匀的局部化流动时,Biot理论将不再适用,BISQ理论充分考虑了“局部流动”效应,应采用BISQ理论;(3)Gassmann方程、Biot理论和BISQ理论仅是孔隙流体效应的部分解,更精确的解或完全解的理论和方程,还需进一步研究和发展。E油田地震油气检测处理及预测研究项目是以三维地震资料为基础,应用Biot双相介质模型油气检测技术,针对E油田石炭系四个目的层开展油气检测处理及储层含油气性的预测。E油田地震油气检测处理及预测研究项目共完成了E油田55km2三维地震资料2个层段的Biot双相介质模型油气检测处理和含油气分布规律的预测研究。根据油气检测成果,结合研究成果对2个储层进行了综合评价,提出有利的含油气预测区。
[Abstract]:Based on the physical basis of seismic reservoir inversion and oil and gas detection, this paper calculates and analyzes the application of Gassmann theory and BISQ theory, and puts forward the applicable scope and limitation of each theoretical calculation. According to the field practice and practical deduction, it can be found that the Gassmann equation can be used in the wave velocity measurement of seismic data (100Hz) and logging data (104Hz). For the laboratory ultrasonic data, the application range of Biot theory is limited to saturated rocks with large porosity and permeability. When uneven localized flow of pore fluid occurs in rock, Biot's theory will no longer be applicable to the theory of "local flow", and BISQ's theory should be adopted as a partial solution of the effect of pore fluid. The theory and equation of more accurate solution or complete solution need to be further studied and developed. The research project of seismic oil and gas detection processing and prediction in E oil field is based on 3D seismic data and applies Biot dual phase medium model oil and gas detection technology. Development of oil and gas detection processing and reservoir hydrocarbon bearing prediction for four target layers of Carboniferous in E Oilfield. Seismic oil and gas detection processing and prediction research project of E Oilfield completed Biot double layers of 55km2 3D seismic data in E Oilfield Oil and gas detection and processing in phase media model and prediction of oil and gas distribution. According to the oil and gas detection results, combined with the research results, the comprehensive evaluation of the two reservoirs is carried out, and a favorable oil-gas prediction area is proposed.
