This paper summarizes the work on applying a "sliding correlation" method to figure out the geological implication for events on a seismogram and then to define the geological stratification for the seismogram, in which attention is given to the depositional features of the continental facies thin interbeds in Songliao Basin and the actual situation of the survey area where the 3-D seismic survey was conducted. We have moreover gone deep into studying the lateral variation of the amplitude and frequency...

This paper summarizes the work on applying a "sliding correlation" method to figure out the geological implication for events on a seismogram and then to define the geological stratification for the seismogram, in which attention is given to the depositional features of the continental facies thin interbeds in Songliao Basin and the actual situation of the survey area where the 3-D seismic survey was conducted. We have moreover gone deep into studying the lateral variation of the amplitude and frequency regarding the sandy formation which is considered to be the main reservoir on an interactive interpretation system based on its features emerging on 3-D profiles. The results were verified with drilling data.

本文针对松辽盆地陆相薄互层的沉积特点,结合茂8井三维地震区块的实际情况,采用“滑动相关法”确定地震地质层位,准确标定了各反射同相轴的地质含义。依据砂岩或砂层组在三维剖面上的特征,充分发挥人机联作解释系统的优势,利用振幅、频率对主要含油层系砂岩的横向变化进行了深入研究,经钻井验证取得了较好的效果。

>=Gully is formed when land is dramatically degenerated in arid valley. In the Yuanmou arid hot valley of Jinsha river, the speed of headward erosion is 50 cm/a to develop gully, and the maximum speed reaches 200 cm/a. The gully density is 3-5 km/hm2, the maximum density reaches 7.4 km/hm2.

>=Gully is formed when land is dramatically degenerated in arid valley. In the Yuanmou arid hot valley of Jinsha river, the speed of headward erosion is 50 cm/a to develop gully, and the maximum speed reaches 200 cm/a. The gully density is 3-5 km/hm2, the maximum density reaches 7.4 km/hm2. The gully formation mainly attributes to the landform characteristics, the quality of geological stratification, the climate characteristics, and the surface structure of soil and the factor of anthropic activity in this region. The biological controlling is quite difficult, the species choice is difficult on the one hand, and the technology of comprehensive controlling is not consummate on the other hand. In view of these characteristics, this experimental project has conducted the massive research and obtained the effective way of gully controlling. After 12 years, the fact has proved that (1) Leucaena leucocephala is first choice species of gully controlling, as a result of its own reproduction ability, causes the system to form the biology community of arbor, shrub, grass level, which is advantageous to use light energy and to conservation water and soil; (2) After controlling, the system' s root soil level is good, which can fix and conserve soil, resist wash out and reduce corrosion speed of gully; (3) The benefits of ecology, society, economy are remarkable, its economic value converts into 3.82 thousand Yuan/hm2.

冲沟是生态系统严重退化的产物,在金沙江流域元谋干热河谷发育的冲沟,溯源侵蚀速度为50 cm/a, 最大达200 cm/a。系统内冲沟的密度为3-5 km/hm2,最大密度达到7.4 km/hm2。冲沟的形成主要与该地域的地貌特征、地层质地、气候特点、土壤表层结构等因素有关。对此类退化系统的生物治理的物种选择是十分困难的,技术也是相对缺乏的,为此,本项目总结用薪炭林树种银合欢和其它物种配合治理冲沟的效果与技术。结果表明:银合欢是干热河谷首选的冲沟治理树种,由于它的自我繁殖能力特强,可导致系统具备乔层、灌层、草层的群落结构,并有较大的水土保持效益;治理后,系统的根土作用层良好,起到固土的作用,防止土壤冲刷,减缓冲沟侵蚀的速度;治理后的社会、生态、经济效益明显,综合经济价值可达3.82万元/hm2。
