【摘要】：為探討多種地球物理方法結(jié)合的重要性,以一個(gè)應(yīng)用地球物理方法布井失敗案例為研究對(duì)象,通過(guò)比較高密度電阻率法、磁共振探測(cè)以及兩種方法結(jié)合的探測(cè)結(jié)果與實(shí)際鉆探資料的差異,分析了每種方法的優(yōu)缺點(diǎn),并借助經(jīng)濟(jì)成本計(jì)算,討論了多種方法結(jié)合的可行性。結(jié)果表明:高密度電阻率法與磁共振探測(cè)各有優(yōu)缺點(diǎn)。高密度電阻率法可很好地判斷地層結(jié)構(gòu)的整體變化,但對(duì)巖性的推斷具有較強(qiáng)的不確定性。磁共振探測(cè)推斷的地層巖性與鉆孔資料基本吻合,但無(wú)法判斷是否有斷層或裂隙帶存在。高密度電阻率法與磁共振探測(cè)結(jié)合推斷的剖面尺度上地層巖性和厚度變化與鉆孔資料基本一致,是揭示地層巖性及含水層位置的有效方法,說(shuō)明應(yīng)重視多種方法結(jié)合的研究及應(yīng)用。相比不采用任何地球物理方法或單一方法,兩種方法結(jié)合的費(fèi)用更低,在實(shí)際應(yīng)用中具有可行性。
[Abstract]:In order to discuss the importance of the combination of various geophysical methods, a case of well layout failure using geophysical method was studied, and the method of high density resistivity was compared. In this paper, the advantages and disadvantages of the magnetic resonance detection and the difference between the results of the two methods and the actual drilling data are analyzed, and the economic cost calculation is used to calculate the advantages and disadvantages of each method. The feasibility of combining various methods is discussed. The results show that the high density resistivity method and the magnetic resonance detection method each have advantages and disadvantages. The high density resistivity method can well judge the overall changes of the formation structure. However, there is a strong uncertainty in the inference of lithology. The stratigraphic lithology inferred by magnetic resonance is basically consistent with the borehole data. But it is impossible to judge whether there are faults or fissures. The variation of stratigraphic lithology and thickness on the section scale inferred by high density resistivity method combined with magnetic resonance detection is basically consistent with the borehole data. Is an effective method for revealing the lithology of the strata and the location of the aquifer, indicating that the research and application of a combination of multiple methods should be emphasized. The cost of combining the two methods is lower than that of not using any geophysical method or a single method, It is feasible in practical application.
