But it has more complicated velocities in the working area, and it locally develops high-speed boulder bed in neocene Xiyu Formation with a velocity 3700—4050m/s, its adjacent formation velocity: 2800—2900m/s; while it also develops low velocity gyprock that has a great variation in thickness (with an increasing thickness from south to north) with a velocity about 4000 m/s, its adjacent formation velocity: about 5000 m/s. And all this is the cause of the complexity of the velocity in this working area; thus to make the No.1 structure in northern YK reliable, in velocity modeling it has much research work to do, and it is also the topic of this graduation thesis.

但在工区内速度较为复杂，工区内局部发育上第三系西域组高速砾岩层，速度约在3700—4050m/s ，围岩速度约在2800—2900m/s，同时全区还发育有厚度变化较大的低速膏岩层，膏盐层的速度大约在4000 m/s，围岩的速度大约在5000 m/s，由此造成了本工区速度的复杂性，因此要准确落实亚肯北1号构造，还要在速度建模等方面做许多的研究工作，这也是本次毕业论文所要研究的课题。

The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

Express as a result that the study area gets close to hydrocarbon generation center, have high-quality coal measures hydrocarbon source rock along with big hydrocarbon generation intensity, so it has abundant gas source and the material foundation to form large scale natural gas reservoir; Evaporitic tidal flat facies of the Ordovician Majiagou Formation in this area is situated in the austral expanded range of the karstification zone, and is the optimum natural gas prospecting targets of the lower-Paleozoic; In the south of study area, there are well-developed delta deposition system sand bodies of Shanxi Formation and Xiashijezi Formation, hence this area becoming the most beneficial Neopaleozoic natural gas enriched region; In this area, the Paleozoic develop various concealed non-structured traps, the natural gas migration and accumulation process is very beneficial and both the cover and the conservancy condition are also very good.

结果表明：研究区紧邻上古生界生烃中心，发育优质煤系烃源岩，生烃潜力大，气源充足，具备形成大型天然气藏的物质基础；区内奥陶系马家沟组发育有蒸发潮坪相沉积，位于北部古潜台的向南延伸带上，是下古生界天然气的有利勘探目标；南部山西组和下石盒子组发育三角洲沉积体系砂体，是有利的上古生界天然气富集区；研究区古生界发育各种隐蔽性非构造型圈闭，天然气运聚成藏过程非常有利，封盖和保存条件也很好。

The coprecipitation is based on the formation of water-insoluble inner complex compounds of the trace elements with-SH group-containing reagent and the formation of disulphide directly in the solution owing to the easy oxidizability of the-SH group. During the formation of the solid disulphide phase the trace elements are coprecipitated.

痕量元素和含-SH基团的试剂形成不溶於水的螯合物，由於-SH基团易被氧化从而直接在溶液中形成固相二硫化物，同时将溶液中的痕量元素共沉淀下来。
