Songzhan region is located in the northern Sanzhao depression in Songliao basin, currently F,Y layers have found oil reservoirs and good exploration prospects. But the understanding of oil source in south Songzhan region rather vague. Oil-source correlation studies have shown that: The oil in south Songzhan region is mature, F,Y oil layers were derived from the same source rock—K1qn1 source rock in Sanzhao depression, secondly K1qn23 source rock. The main K1qn1 source rock for the generation and expulsion period was the Mingshui final deposition to the current moment.
Key words: south Songzhan, F,Y oil layers, source rocks evaluation, oil-source correlation
Clouds make up more than 50% of the earth planet, where absorb, reverse, dispersing and scattering radiation connecting to it, while sending a red thermal radiation according to their temperature. In this work the calculation the daily and seasonally of the rate of change dew point temperature and density of saturated water vapor to high (0.2 - 13) km to seasons (winter and spring) and high (0.2 - 18) km to seasons (summer and autumn) by using Model Cloudy Atmosphere (MCA) for the days of the study for one year for Baghdad International Airport station in Iraq. Through drawing relationship vertical change for each of the dew point temperature and density of saturated water vapor found that both decreases with height to the height of 12 km, though the clouds at all the increase have different characteristics in terms of the dew point temperature, density and pressure of saturated water vapor and water content so the atmosphere is a heterogeneous.
Keywords: - Cloud cover, Dew point temperature, Thermal radiation, saturated water vapor density, Baghdad.

Through the analysis of sedimentary microfacies, sand-body distribution, structural and fault, and the impact of oil-water distribution of the study area, we think the study area's oil-water distribution regularity is controlled by the fault-sand disposition relationship of regional tectonic. Tectonic block controls the oil enrichment degree and the oil-water envelopment. Oil horizontal distribution is controlled by the fault of WWE and WEE. The well controlled by sand body high angled with fault has best oil production test conclusion.

Oil and gas lateral diversion is the study of Jizhong depression left key problems of oil and natural gas accumulation in Liuhu area, according to the study area, 84 well data and 3D seismic data to study the control factors of lateral shunt in the Liuchu area. The following results were obtained: 1) cap rock development is a prerequisite for fault reservoir lateral diversion; 2) reverse oil source faults "convex ridge" near upper reservoir is lateral injection point 3) in the lateral injection point's reservoir physical properties determine the lateral distributary stratigraphic position, and the dominant migration pathway is drawn, This conclusion can guide the exploration in the area of Liuchu area, which can provide reference for other exploration.
Keywords: lateral diversion, dominant migration pathway, shale stratum ratio, Liuchu area, injection point.

In view of the actual situation that there exists advantage channel in long-term water flooding
sandstone reservoir, on the basis of static and dynamic data in oilfield development, through a comprehensive
study of core description, logging interpretation, dynamic analysis, we have established different levels of logging
response standard of advantage channel, at the same time analyze the geological forming conditions, which
provides a quantitative basis for effective identification of the flow channel. It is of great significance to deepen
the understanding of oil-water movement rule of old water-drive oilfield.

Distribution characteristics of interlayer are main controlling factors of heterogeneity in thick oil layers. According to the channel sand body in Xinli oilfield Ⅵ Block, taking the core analysis and logging data, the internal interlayer can be divided into three categories: Argillaceous interlayer, Calcium interlayer and Physical interlayer. The standards of quantitative of all kinds of interlayers are established as Well. It provides a favorable effect for recognition of single Well vertical interlayers and a train of thought for identification of interlayers, at the same time lays the foundation for research on remaining oil distribution and development plan in the later period of oilfield.

Jin 31-Jin 146 well area, Liaohe depression, Bohai Bay has a complicated structure, from the conditions in recent years, some of the oil and gas well production was not consistent with the performance of adjacent Wells, because of never done fine geologic research in Jin 24 pieces and Jin 33 wellblock,there was unconfirmed structure and low degree of awareness of the main purpose and main research layer section, conventional cognition is difficult. To fully tap the work area of oil and gas potential, it was necessary to carry out the work area related geological research. This paper applied data logging interpretation results, chip information, grading analysis and physical properties such as test data to srudied the petrology characteristics and discussed the diagenesis. The results showed that there was poor physical properties of the work area, compaction is relatively weak, with the increase of buried depth the diagenesis enhancement and physical property becomes poor.
Key words: Liaohe depression; petrology characteristics; diagenesis
Video Object Detection is more demanding in various video surveillance application i.e., public and private domains. The video object detection, identify similarity of objects and object parts between consecutive frames of video. The moving object detection, analyze the video frames with its foreground and back ground image objects. The foreground image objects are usually considered to be moving ones and the background objects are considered to be static. Recently several contributions in the video object detection had been made, but lacks detection accuracy and unaddressed background object detection in the video frames. In this paper, a novel framework of object detection for video surveillance called Improvised Enhanced Laplacian Threshold (IELT) technique. The improvisation of ELT is done with Gaussian-based Neighbourhood Intensity Proportion (GNIP). The IELT technique initiates the process of video object segmentation, object tracking and finally object detection. In video object segmentation, the input video frames are segmented with the help of Median Filter-based Enhanced Laplacian Thresholding to improve the video quality. In object tracking, Color Histogram-based Particle Filter is applied to the segmented objects by computing the likelihood function, particle posterior and particle prior function based on the Bayes Sequential Estimation model. Finally, the object detection is performed with improvisation of enhanced Laplacian threshold by analyzing neighbourhood Intensity proportion of moving object contour. IELT with Gaussian distribution of neighbourhood proportion improves video object detection accuracy and identify background moving object detection. Experimental evaluation is done on IELT with performance metrics such as time taken for object segmentation, object tracking and detection accuracy, and peak signal-to-noise ratio of moving video object frames. The data set sample of different videos extracted from Internet Archive 501(c) (3), a non-profit organization on effective video object detection for video surveillance. Experimental analysis shows that the GNIP framework is able to reduce the object segmentation time by 52% and improve the video object detection accuracy by 12% compared to the state-of-the-art works.

In recent years, with the constant breakthroughs of the exploration in TAMTSAG basin, it's accumulational controlling factors and rules are more and more concerned by experts. Based on the analysing of reservoir's types and distributional rules,we divided the formation into three petroleum system vertically.According to the analysing of lower petroleum system,,we can find the key factors which control the distribution of oil and gas by antithetic faults,and then establish a representative accumulational model.Finally,these works would guide the exploration effectively.

In this paper, the tectonic characteristics in Gulongnan region of Songliao basin were studied.The study area is divided into seven tectonic units. Fault intensive belt is NNW direction. In the northern area, the faults are tectonic genesis ,in the southern area,the faults are tectonic mixed with non-tectonic genesis.Fault activity show for polyphase. Based on the balanced section recovery, analyzed the tectonic evolution stages of the study area.
