The Upper Submember of the 4th Member of the Shahejie Formation in Huimin Depression represents one third-order sequence according to sequence stratigraphic analysis based on well log and seismic reflective data. Lowstand, lacustrine transgressive and highstand systems tracts can be recognized based on the stacking patterns and changes of lithology and lithofacies. The sequence stratigraphic correlation of well-tie sections made it possible to construct the regional stratigraphic framework.

With the development of oil drilling and the increase of the deep ocean drilling,the requirements of drilling additives were also promoted to satisfy the high temperature resistance and salt resistance.2-Acrylamido-2-methylpropane sulphonic acid is an acrylamid derivatives with -SO3H and -CH2=CH2- in its molecular structure.

随着世界能源需求的增加和钻探技术的发展，向地层深部挺进，向深地层要油气已成必然。在我国，这种现象尤为明显，作为全国石油天然气产量的主力接替区的西部，其石油资源量的73%、天然气资源量的52%都埋藏在深地层。

应用层序地层学解释方法对乌尔逊凹陷北部下白垩统地层进行了层序地层分析，将其划分为4个层序和4种层序类型，即简单断陷层序、快速断坳层序、同生断坳层序和简单坳陷层序。

The area of exploration is 120km2.The lower strata of Es2 are terraneous basin sediments. The analytic method of traditional sequence stratigraphy theory is stemmed from sea sediment studies, and how to apply the theory to the exploitation of land sediment.

该油田古近系沙河街组沙二下亚段地层属陆相断陷湖盆沉积，传统的层序地层学分析方法起源于海相地层应用中，如何将其应用到陆相开发方面一直是人们比较关注的一个问题。

During the preresearch on the testing well location selection in the south of western depression, three kinds of process and research work have been done according to the log datum on Well Moushen:(1)Formation analysis and formation pressure evaluation which verdicts that formation under 5198.5m is not of Trias, whereas is still in Permian, and abnormal formation pressure phenomenon exists in Members 1 and 3-4 of Shahejie Formation;(2)Re-interpretation of oil and gas formation and evaluation of reserve formation;(3)Evaluation of oil source rock. Members 1 and 3-4 source rocks of Shahejie Formation have good capability of oil generation.

在东濮凹陷西洼南部探井选位的前期研究中，根据该井的测井资料情况，做了三方面处理和研究工作：①地层分析和地层压力评价，认为5198.5m以下的地层不是三叠系而仍是下第三系，沙一段和沙三段—沙四段存在高压异常；②重新解释油气层和评价储集层，在沙三段—沙四段发现6层12.87m厚可疑油层；③评价油源岩，认为沙一段和沙三段—沙四段油源岩具有较好的生油能力。

In recently 10 years, people pay much attention to a new induction logging technology called fully triaxial induction logging. It can detect and characterize resistivity anisotropy and provide the information of formation dips and azimuths that are essential in charactering and developing low-resistivity reservoirs such as thinly laminated sand-shale sequences.

近十年发展起来的三轴感应测井由于能探测地层的电各向异性，提供关于地层水平和垂直电导率以及地层倾角和走向的信息，这对砂—泥岩薄交互油储层组这类&低阻产层&的识别和开发有着重要意义，倍受人们的重视。

Based on the early geologic studies, more integrated strata units and frame was established in Yunnan and Guizhou. The characteristic of macroscopical lithofacies and paleogeography was also raveled basically in this area. It was ascertained that some perfect developed PTB sections from marine via paralic to terrestrial facies lie in western Guizhou and eastern Yunnan. What's more, the stratigraphic sequence of Marine PTB or Terrestrial PTB across the PTB in this area is similar to that of the Meishan Section.
