Gpr is a newly developed hi - tech survey technique used to detect shallow ground electric differences . we applied gpr to more than 100 projects in zhujiang river delta and hongkong , and obtained good reputations . the application scope involves stratigraphics division , outining of filled stones in the muddly beach , geotechnical prospecting of old wall , karst detecting in the limestone terrain , caving detecting , landslide and slop surveing , the division of wea - thering zone , onion weathering zone , fracture zone and fau - lted zone in the granite area , detecting of buried objects cable , metal nonmetal pipe , channel , air raid she - lter etc . underground in the urban city , archaeology , tracing of orebody , coal measures strata division , testing of the dam and grouting site , quality checking of the surface and foundation of the highway 的一種高新技術。我公司運用世界最先進的探地雷達設備在珠江三角洲地區和香港開展了百余項探地雷達檢測項目,獲得了良好的聲譽,并被作為深圳市建設局1998年度建設科技成果推廣項目。它主要應用于:山體土石方檢測路基不同回填物界面檢測填海回填物巖溶檢測樁基無損檢測地下管道探測地下隱蔽物探測考古斜坡滑體探測地質結構探測湖底探測高速公路路面及路基檢測。

Then i discussed methane desorption properties including cbm - bearing saturation , critical desorption pressure , the ratio between critical desorption pressure and original coal reservoirs pressure and difference of terra decompression ; cbm - bearing characteristics of coal seams including measured / academic cbm - bearing content , coalbed methane resources content and cbm resources abundance , etc . the author respectively gave a brief account of the basic characteristics of ancient and today ' s geothermic field at 1000m and 2000m depth , coal measure strata pressure field at the depth less than 1600m , structural stress field from jurassic to present , and ancient and today ' s fluid potential field ( that is water potential and gas potential distributing in coal measure strata ) 分別簡述了準噶爾盆地1000m及2000m深度今古地溫場、 1600m以淺的煤系地層壓力場、侏羅紀至今地應力場及煤系地層水勢與氣勢分布的今古流體勢場基本特征,進而對這“四場”特征及其互動關系與煤儲層物性、可采性及煤層氣聚集的關系進行了探討。從構造背景、構造演化及構造類型幾方面論述了本區構造作用的控氣特征。

By comprehensively applying the data of logging , drilling and seismic data , and depending on basin - modeling technology , and synchronously , integrating fluid inclusion homogenization , raman spectrum ingredient assay and autogeny illite age - determining technique , we had the numeric modeling of carboniferous - permian coal measure , including burial history , terrestrial heat history , hydrocarbon - generating and hydrocarbon - expulsing history and reservoir - forming history , at the wenan slope of jizhong depression , in the bohaiwan basin 本文綜合利用鉆井、測井、地震等資料,應用盆地模擬技術,結合流體包裹體測溫、包裹體拉曼光譜成分分析及自生伊利石測年等先進方法,對渤海灣盆地冀中坳陷文安斜坡石炭?二疊系的埋藏史、地熱史、生排烴史和成藏演化史進行了數值模擬。

Oil - source correlation studies show that the oil sample in well yi535 did not mainly derive from coals , but mainly originated from the coal measure mudstones and / or carbonaceous shales . the condensates in tiergen structure originated from coals with a later stage of maturation . the oils in yinan 2 well might originate from the coal measure mudstones with relative high maturity , which bear the same source as the oils in yi535 well but with different mature level 精細的油-巖直接對比發現:依535井原油并非典型的煤所生,它主要來自煤系泥巖和或炭質泥巖,而提爾根構造帶的凝析油主要來自成熟晚期的煤;依南2井凝析油來自煤系泥巖,而不是三疊系湖相泥巖。

On the basis of comprehensive analyses on hydrocarbon accumulation conditions in the four representative foreland basins , kuqa basin , southern junggar basin , western sichuan basin and northern margin of qaidam basin , some conclusions are made as follows ; the foreland basins in central and western regions of china are characterized by multi - set source rocks dominated by coal measure ; heterogeneous reservoirs ; multiple and sealing cap nick ; anticline traps ; unblocked transport system composed of fault , unconformity and highly permeable sand body ; anti poor conservative conditions . etc 在綜合分析和對比庫車、準南、柴北緣和川西等具有代表性的前陸盆地的油氣成藏條件的基礎上指出,中西部前陸盆地具有以煤系為主的多套源巖,發育非均質儲集層,多套多封閉性的蓋層,以背料為主要圈閉;斷裂、不整合和高滲透砂體組成良好輸導體系,保存條件較差等特點。

Being beaten the coal measures is together achieved program control and the industry tv monitoring system and is beaten the coal measures dependability together to the raise , automation degree , decreases personnel staff in post with they labour intensity , strengthening is beaten coal process operation administration and the . save energy administration , achieving the condition maintenance havees the very much significant sense 輸煤系統實現程序控制和工業電視監視系統對提高輸煤系統的可靠性、自動化程度,減少崗位人員和他們的勞動強度,加強輸煤過程的運行管理和節能管理,實現狀態檢修具有非常重要的意義。

On the basis of analyzing and chemically examining a large numble of samples , through comprehensively studying the reservoiring geological conditions as hydrocarbon generation , petrophysical property , reservoir - caprock assemblage and lithologic trap type , by use of mathematical statistics , it was considered that yulin gas field is located in the greatest hydrocarbon - generating intensity area in the basin and its hydrocarbon source rocks are the permo - carboniferous coal measure strata , thus possessing the material conditions of forming large - sized gas fields 通過大量的化驗分析樣品數據,采用數理統計的方法對生烴條件、儲層物性、儲蓋組合配置、巖性圈閉類型等成藏地質條件進行了較為深入的研究,認為榆林氣田處于鄂爾多斯盆地最大生烴強度區,其烴源巖為石炭二疊系煤系地層,具備形成大型氣田的物質條件。

Through research , the organic matter of source rocks in carboniferous - permian coal measure strata began first hydrocarbon - generating in mesozoic , and the first hydrocarbon - filling took place . but , because of yanshan movement later , the carboniferous - permian strata rose , as a result , the first hydrocarbon - generating and reservoir - forming paused ; in early tertiary period , because carboniferous - permian strata dipping forward east originally turned into dipping forward west , the prototype of faulted block began to form gradually ; by the end of sha - 3 period of early tertiary , the paleogeotherm of carboniferous - permian strata exceed the mesozoic ' s temperature again , and accordingly , abundant hydrocarbon was generated and expulsed secondly . the trap continued to develop ; from the end of late tertiary to quaternary , the second hydrocarbon - generating and expulsing got to its peak , and the second reservoir - forming was over 研究表明,本區石炭?二疊紀烴源巖在中生代發生一次生烴和排烴,并有油氣充注,后因燕山運動導致地層抬升,一次生烴和成藏過程中止;在早第三紀,原來東傾的地層變為西傾,斷塊圈閉開始具雛形;至早第三紀沙二末期,石炭?二疊系的大部分地層古地溫再次超過中生代一次生烴的溫度,開始二次生烴和排烴,圈閉持續發育;晚第三紀末?第四紀,二次生烴、排烴達到高峰,二次成藏完成。

At the moment , being living , the coal measures is beaten together in our country thermal power plant , the leather belt transport aircraft control mode is 3 kinds : local control , lumping single control , lumping microcomputer program control 因此,皮帶運輸及控制方式的合理選擇,直接關系到整個輸煤系統的安全運行。目前,在我國火力發電廠輸煤系統中,皮帶運輸機的控制方式有三種:就地控制、集中單獨控制、集中微機程序控制。

The leather belt transport aircraft is living , and the coal measures is beaten together in thermal power plant , undertake quan chang coal transportation , advance , distribute and so on work , is being beaten the coal measures capital equipment together 輸煤設備的控制系統可分為皮帶運輸機(包括篩碎設備、除鐵、除木、除塵設備和計量設備)的控制、卸煤設備的控制、煤場機械的控制和給配煤系統設備的控制四個部分。

Carboniferous strata , more than 1000m in thick in the area of hexi corridor to bayan haot basin , is the coal measures of transitional phase , in which there are three kinds of hydrocarbon source rocks including dark mudstone , limestone , coal and carbonaceous mudstone 摘要河西走廊至巴彥浩特盆地地區石炭紀地層厚逾千米,是一套海陸交互相含煤巖系,發育暗色泥巖、灰巖、煤層及碳質泥巖等3大類烴源巖。

According to the basic principle of sedimentary geochemistry , two geochemical sections from dongying sag of bohai bay region and turpan basin were selected as the standard models of deep - water rift - subsidence basin and shallow water coal measure basin , respectively 結果表明,該盆地侏羅系地層元素特征與東營凹陷很相似,由此推知其古環境在更大程度上傾向于東部深水斷陷湖盆。

In triassic and lower - middle jurassic , there is the acid diagenetic ambient , where inter - pore fluid is from the organic acid released from the coal measures during diagenesis 三迭系至中下侏羅紀煤系為酸性成巖環境,它們在成巖過程中釋放的有機酸使隙間流體呈酸性。

Hence , the leather belt carrys the rightful selection of control mode , immediately affect entirely to be beaten the coal measures secure operation together 皮帶運輸機在火力發電廠輸煤系統中,承擔了全廠來煤的運輸、提升、分配等工作,是輸煤系統的主要設備。
