The lacustrine carbonate rocks occur on a wide range of scales in the palaogene and neogene strata in the hoh xil basin , qinghai , and constitute an important part of the miocene wudaoliang group sediments 摘要湖相碳酸盐岩在可可西里盆地的古、新近纪地层中分布广泛，更是中新统五道梁群沉积的主要组成部分。
Lacustrine dolomite reservoir in the hinterland of biyang sag is mainly distributed at no . 2 and no . 3 sections of hetaoyuan with its development controlled mainly by the lithology diagenesis and nose ? like structure 泌阳凹陷腹部湖相白云岩油层主要分布在核二3和核三2段,其发育程度主要受岩性、成岩作用和鼻状构造控制。
2 . by using seismic stratigraphy to lacustrine environment , sedimentary frameworks of mahu depression have been studied . results indicated that fan - delta were the dominant facies of permian in mahu depression 2 、运用震地层学理论对玛湖凹陷沉积条件进行了研究，结果认为，玛湖凹陷二叠系发育以扇三角洲为主的沉积体系。
Abstract : lacustrine dolomite reservoir in the hinterland of biyang sag is mainly distributed at no . 2 and no . 3 sections of hetaoyuan & nbsp ; with its development controlled mainly by the lithology diagenesis and nose ? like structure 文摘:泌阳凹陷腹部湖相白云岩油层主要分布在核二3和核三2段,其发育程度主要受岩性、成岩作用和鼻状构造控制。
Though better in property and richer in reserves , the lacustrine reef reservoir in the basin is not homogeneous in distribution and varies in thickness , therefore it is hard to be explored and developed with traditional ways 生物礁储层的物性极好，储量较大，但湖相生物礁储层在柴西地区分布不均，变化很大，难以用传统的方法进行勘探和开发。
The basin tectonic model : it is intermont basin during late jurassic to early cretaceous , developed into faulted - lacustrine basin in eogene , and evolved into depression in neogene and quaternary “盆地”构造发育模式为：从晚侏罗世到白垩纪末期发育的山间“盆地”开始、发展到早第三纪断陷湖盆的发育、再演化为晚第三纪及第四纪地陷发育阶段。
We suggest that the favorable reservoir facies within ganchaigou formation in west qaidam basin are delta front facies , fan - delta front facies , dam - and - beach facies of the littoral and shallow lake , lacustrine floor fan facies and carbonates facies 强调了三角洲相前缘、扇三角洲相前缘、滨浅湖滩坝、湖底扇以及碳酸盐岩沉积是西部地区干柴沟组有利的储集岩相带。
According to the analysis of petrology , we find that chang 6 oil - bearing is consisted with middle size sandstone and fine sub - sand . chang 6 sandstone belongs to system of lacustrine deltas and mostly influenced by river 沉积相的研究主要从野外露头， 12口井的岩心观察入手，结合大量科研资料综合分析表明，靖安油田长6油层组属于湖泊沉积体系中湖泊三角洲分布区。
For the high - class highways builded on the area of lacustrine deposits soft soil , because earth fill of subgrade is very high and construction period is very short , the controlling of subgrade stability and settlement are the two key techniques 对于通过湖相沉积软土地区的高等级公路，当路基填土较高、工期较短时，必须解决地基稳定性控制及沉降控制两个关键技术问题。
The sedimentary facies of sihetun area may be divided into alluvial - fluvial , shore - lacustrine , semi - deep and deep lacustrine ; while those in yixian area can be classified into alluvial - fluvial , fluvial , shore - lacuatrine and lacustrine facies 四合屯地区的沉积相可以划分为冲积扇河流相、滨湖相、半深深湖相；义县地区沉积相可以划分为冲积扇河流相、河流相、滨浅湖与湖相。
