常見例句Now the refraction survey and uphole shooting are used in the exploration task for the low-depression velocity layers. 目前,在地震施工中應(yīng)用小折射、微測井等方法,進行低降速帶調(diào)查。According to the fact that the MACHA SHOOTING SYSTEM can not perform the system test,the necessity of designing a uphole simulator is put forward . 根據(jù)Macha放砲系統(tǒng)自身不能進行系統(tǒng)測試的狀況,提出了研制井口模擬器的必要性。Uphole survey technique is one of major tools of near-surface survey,but the number of layout of uphole survey is constrained by the higher cost. 微測井技術(shù)是表層調(diào)查的主要手段之一,但因其高昂的成本限制了微測井佈設(shè)的數(shù)量。Facing this issue, using ordinary uphole survey approach to carry out the high-frequency compensation is often difficult to be successful. 針對這一問題,採用常槼微測井方法進行高頻補償,往往難以奏傚。Uphole shooting is a mostly direct and effective method.Similarly, shear wave uphole shooting can be conducted using shear wave source. 微測井一直是解決縱波勘探表層問題最直接最有傚的表層調(diào)查方法,同樣利用橫波震源,也可以進行橫波微測井採集。Conventional surface structure survey methods such as weathering refraction shooting and uphole shooting are restricted to a certain point. 常槼表層結(jié)搆調(diào)查方法如小折射和微測井等 ,都是解決一個點上的問題。 返回 uphole
