The physical properties of middle jurassic reservoir are influenced by the lithologic characters of sandstone 砂巖的巖性特征對(duì)儲(chǔ)集層的物理性質(zhì)具有明顯的影響作用。
With two exploration examples , this paper recounts the application of geological radar to detecting fractures , karst and old mined - out galleries in media of different lithologic characters and its effects 摘要通過(guò)3個(gè)勘察實(shí)例,闡述地質(zhì)雷達(dá)技術(shù)在花崗巖、石灰?guī)r及砂巖等不同巖性介質(zhì)中探測(cè)斷裂、巖溶和舊開(kāi)采礦坑中的應(yīng)用效果。
In this paper , the geologic features of carlin type gold deposits in tangxinzhai are expounded , relations of metallogenic with lithologic characters , structure and wall rock alterations are summed up , and its metallogenic conditions and metallogenesis are described preliminarily 本文結(jié)合區(qū)域地質(zhì)背景敘述了塘新寨微細(xì)浸染型金礦床地質(zhì)特征,探討了成礦與地層巖性、構(gòu)造、蝕變的關(guān)系,并初步探討其成礦條件與成礦作用。
Rebounding displacement of slope and axial force of anchor bars increases as the increment of the included angle of the rebounding displacement vector and x positive axis will reduce as the increment of horizontal tectonic stresses . the reduction of lithologic characters and weak interplayer have unfavorable influence on stability 支護(hù)錨稈軸力也增大;隨著水平構(gòu)造應(yīng)力的增加,回彈位移矢量與水平x軸正方向所形成的角度將減??;邊坡巖體巖性參數(shù)的弱化和軟弱央層的存在都對(duì)邊坡的穩(wěn)定造成不利的鍘惻。
On studying of them . using the testing outcomes of gas fully , lithologic characters . strata sequence , sand body shape , sequence sectional structure in aeration zone and main channels migrating pattern on different phases have been analysed . for futher reservoir , cap , source rock and oil gas expiortion 在此研究基礎(chǔ)上,充分利用有關(guān)的試氣成果資料,詳細(xì)分析了含氣層的巖性、層序地層特點(diǎn)、砂體的形態(tài)產(chǎn)狀特征、不同時(shí)期主河道分布與遷移的規(guī)律及含氣層的剖面結(jié)構(gòu)特點(diǎn)等。
