Research on structural damage diagnosis based on structural high order local modes 基于結(jié)構(gòu)高階局部模態(tài)的損傷診斷研究
In addition , side - tracking in old wells can produce residual oil between wells and on structural high , improve pattern arrangement , and control bottom water coning ; it is an effective method for developing minor fault block reservoir with complex lithology and bottom water 同時,老井側(cè)鉆既能挖掘井間及高部位剩余油,完善井網(wǎng),又能有效控制底水錐進(jìn),是復(fù)雜底水小斷塊油藏經(jīng)濟(jì)高效開發(fā)的措施方法。
5 . integrated description of the reservoir showed that the buried depth of the dujiatai formation was deep , the distribution of the formation was stable with good contiguity . there was no united woc , the distribution of the oil layer were mainly confined by structure , the types of the reservoirs were lithology - struture reservoirs , hydrocarbon mainly concentrated on structural highs 5 .油藏綜合描述研究表明,該區(qū)杜家臺油層埋藏較深,油層分布穩(wěn)定、連續(xù)性好,沒有統(tǒng)一的油水界面,油氣分布主要受構(gòu)造控制,油藏類型主要為巖性一構(gòu)造油藏,油氣土要富集在構(gòu)造的高部位。
The results show that the difference of the properties between the two tv towers is great , and the influences of the structural high order modes as well as the structural cross spectral density on the internal force are obviously , so that this effects on structural internal force must be taken into account comprehensively in the aseismic design of tall tv tower 結(jié)果表明,洛陽電視塔與東方明珠電視塔的內(nèi)力演變譜密度特性具有很大的差別,結(jié)構(gòu)的高階振型及結(jié)構(gòu)的互譜密度對結(jié)構(gòu)的內(nèi)力具有較大的影響,因此結(jié)構(gòu)的抗震設(shè)計應(yīng)綜合考慮這些因素對結(jié)構(gòu)內(nèi)力的影響效應(yīng)。
