【摘要】:本文從地震儲(chǔ)層反演,油氣檢測(cè)的物理基礎(chǔ)出發(fā),對(duì)目前流行的Gassmann理論、Biot理論和BISQ理論的適用情況進(jìn)行了推算分析,提出每種理論計(jì)算的適用范圍與局限;針對(duì)現(xiàn)場(chǎng)實(shí)踐與實(shí)際推演可知:(1)Gassmann方程可用于地震數(shù)據(jù)(100Hz)和測(cè)井?dāng)?shù)據(jù)(~10~4Hz)的波速測(cè)量中,對(duì)于實(shí)驗(yàn)室超聲波測(cè)量數(shù)據(jù)(~10~6Hz),盡量少用;(2)Biot理論應(yīng)用范圍限于孔隙度大,滲透率的飽和巖石,當(dāng)巖石中的孔隙流體發(fā)生不均勻的局部化流動(dòng)時(shí),Biot理論將不再適用,BISQ理論充分考慮了“局部流動(dòng)”效應(yīng),應(yīng)采用BISQ理論;(3)Gassmann方程、Biot理論和BISQ理論僅是孔隙流體效應(yīng)的部分解,更精確的解或完全解的理論和方程,還需進(jìn)一步研究和發(fā)展。E油田地震油氣檢測(cè)處理及預(yù)測(cè)研究項(xiàng)目是以三維地震資料為基礎(chǔ),應(yīng)用Biot雙相介質(zhì)模型油氣檢測(cè)技術(shù),針對(duì)E油田石炭系四個(gè)目的層開展油氣檢測(cè)處理及儲(chǔ)層含油氣性的預(yù)測(cè)。E油田地震油氣檢測(cè)處理及預(yù)測(cè)研究項(xiàng)目共完成了E油田55km2三維地震資料2個(gè)層段的Biot雙相介質(zhì)模型油氣檢測(cè)處理和含油氣分布規(guī)律的預(yù)測(cè)研究。根據(jù)油氣檢測(cè)成果,結(jié)合研究成果對(duì)2個(gè)儲(chǔ)層進(jìn)行了綜合評(píng)價(jià),提出有利的含油氣預(yù)測(cè)區(qū)。
[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.
