根据对准噶尔盆地典型低演化阶段侏罗系煤系烃源岩热模拟实验所产烃类气组分碳同位素的分析测试,研究了盆地赋存天然气的类型、热演化程度和赋存的地质条件。认为:盆地腹部陆南凸起以高演化阶段煤型气为主,源岩可能为盆地东部发育的石... 根据对准噶尔盆地典型低演化阶段侏罗系煤系烃源岩热模拟实验所产烃类气组分碳同位素的分析测试,研究了盆地赋存天然气的类型、热演化程度和赋存的地质条件。认为:盆地腹部陆南凸起以高演化阶段煤型气为主,源岩可能为盆地东部发育的石炭纪煤系;低演化阶段油型气主要赋存在盆地东部油气区;盆地南缘特殊构造地质条件和烃源岩热演化条件是构成不同演化阶段天然气分别聚集或混源聚集的原因。 展开更多

[Objective] The paper was to study the climate conditions of celery indus- trial belt in Huluhe Basin. [Method] Using the climate data of Xiji national basic sta- tion during 1981 and 2010, the meteorological data during crop growth period in 3 automatic weather stations along Huluhe Basin were carried out regression analysis, and the climate condition of west celery industrial belt was conducted hierarchical clustering analysis by SPSS. [Result] West celery industrial belt along Huluhe Basin could be divided into 2 growing regions: partially southern warm, rainy and early mature region, partially northern cold, rainless and late mature region. Years of practice proved that the small climate differences within 2 planting regions were more obvious, so these 2 planting regions could be further divided into 4 subre- glens: Xinglong warm, rainy and early mature subregion, Xiaohe thermal, rainy and partially early mature region, Jiqiang cool, rainless and middle mature subregion and Xinying cold, rainless and late mature subregion. [Conclusion] The study has refer- ence value for determination of different sowing time, different fertilizer and irrigation scheme, pests and diseased control and marketing time of west celery under mulch- sanded bunch plantation in market economic condition. 展开更多
