古地理分析表明,研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地;早中侏羅世,演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積;進入中晚侏羅世,其古地理表現為一個陸屑淺海有障壁海岸;到了晚白堊世,研究區表現為以含煤沉積為特徵的三角洲相沉積。Moreover, the drilling process needs to be refined so that the deeper aquifers are not poisoned by arsenic - bearing water trickling down from the shallow aquifers through the boreholes themselves
還有,鉆孔的過程必須要改良,較淺含水層中的砷才不會經由鑿孔向下蔓延,進而污染了較深的含水層。According to the correlativity between stomatal conductance and soil moisture, root system distribution and soil water profile, these greenbelt should irrigate when soil moisture is high, and their scheming wetted soil layer depth is shallow in slow consumption stage ; irrigate when soil moisture is low, and their scheming wetted soil layer depth is deep in quickest consumption stage ; irrigate when soil moisture is higher, and their scheming wetted soil layer depth is deeper hi slower consumption stage
在草坪弱、泡桐中耗水期時,土壤高含水量時即須淺層灌溉補水,以滿足其萌發需要;中、強耗水期,可低土壤含水量時深層灌溉補水;微耗水期,為安全越冬,又需中深層灌溉補水。最大灌水定額由灌溉飽和點、補償點和計劃濕潤深度確定。It is very important work for exploration to identify and evaluate oil layer, water layer, or gas layer from reservoir, and it is difficult for petroleum scientists to identify and evaluate light oil, whose color is weak, oiliness is light, volatility is strong, hydrocarbon saturation is low and fluorescence will disappear after a stretch
油氣水層的識別與評價是勘探工作的重要環節,其中輕質油層的識別與評價是油水層識別與評價的難點。輕質油在常溫常壓下含油顏色淺、油質輕、易揮發、含油級別較低、時間略長熒光普照顏色無,容易漏失,進而漏算儲量。It result in water level rising, hypo - salinification aggravating, sediment silting up, the lake atrophy, marsh extending and nature disaster such as droughu waterlog ^ salinification occurring frequently. completely analysis to geology and hydrology conditions of the district along yellow river in shandong has been applied in this paper and aquifer ' s hydrological characteristic and subsurface flow ' s characteristic have been analysed as keystone in the paper. after finding out the distribution rule and formation conditions of the shallow layer " s ground water resource, divide the district into three hydrological sections according to hydrological conditions and subsurface flow characteristic
