    Abstract: Synthetically using the empirical statistic method, porosity—permeability intersection method minimum flow pore throat radius method and oil test method. We can seek for the physical property lower limit of different depth of deep reservoirs of Yuan Yang Gou. According to liner regression, we achieved the functional equation which shows functional relationship between physical property lower limit and depth. At the same time, we also talk about the characteristics of different methods and the control factors of physical property lower limit The results show that although the methods have advantages and disadvantages, we should use these methods in a synthetically way. However, the porosity lower limit of the study area mainly is controlled by reservoirs which is based on primary pore and mainly affected by the depth, it also presents a good liner relationship with the logarithm of depth of burial .Permeability lower limit is mainly affected by reservoirs that is based on secondary pore Permeability lower limit shows a exponential relationship with depth of burial too, but its relative relevance is bad.

    Abstract: Asbestos is a natural fibrous silicate mineral in general, and has good abrasion resistance, heat insulation properties, and is used extensively for construction, insulation, friction, sealing materials. However, it was discovered that asbestos is inhaled into lungs easily lead to pulmonary fibrosis, then induced cancer, so asbestos has been identified as carcinogens. In this paper, pretreatment methods and detection methods for asbestos were introduced. Currently pretreatment methods for asbestos mainly include an acid method, an organic solvent method, potassium chloride solvent method, ashing method, grinding method and mixing using a variety of methods for asbestos pretreatment. Detection methods for asbestos mainly include XRD, PLM, SEM, PCM, TEM, IR, DTA, which can qualitative analysis and quantitative analysis for asbestos. In this paper, the above a variety of methods are introduced, and the characteristics of each method are analyzed, the advice of more appropriate for asbestos detection method is proposed.

    Abstract: Based on ten well cores, seventeen hundred logging data and initial potential data, sedimentary characteristics and mode of shallow lacustrine fluvial-dominated delta of Putaohua oil layer in the east of Sanzhao depression were analyzed. It is realized that distributary channel sandbodies as sand body framework of this delta system, which is abundant, closely and narrow, and the framework of sand body is in a large number of narrow banded shape (mostly 200 ~ 300m), and can extend hundreds of kilometers of continuous, dense, overall was SW, and combines well with other types sand surface to become a better distributary channel sand body. Based on understanding of sedimentary background, developmental process, sedimentary characteristics and sedimentary facies type of Putaohua oil layer in Sanzhao depression, sedimentary mode of shallow lacustrine fluvial-dominated delta is established in the study area, and sedimentary mode of five subfacies is further divided: Delta distributary plain subfacies is mode of fluvial-dominated belt body; Transition region of front-distributary plain is mode of inshore; Inner front is mode of fluvial-dominated belt body; Transition region of inner front-outer front is mode of fluvial-dominated sheet sand; Shallow lacustrine fluvial-dominated delta outer front is mode of tide-dominated sheet sand; Also pointed out that overall shows NE –SW trending submerged distributary channel sandbodies which is abundant, closely and narrow is the main reservoir of the study area. It provides the solid geological basis for the establishment of spatial distribution pattern of reservoir; identify the causes of mainly monosandbody and further tapping the potential of oil field.

    In: Applied Mechanics and Materials, Trans Tech Publications, Ltd., Vol. 571-572 ( 2014-6), p. 1030-1036
    Abstract: In deep research and analysis on WSN security routing protocols and according to the rational development trend of the sensor nodes, this paper proposes a new WSN security routing protocol based on the theory of the static game—GBR. GBR describes the interactions in a static game model using rational characteristics of nodes. When selecting the forwarding node, neighboring nodes decide whether to participate in forwarding data through game, and prevent the destruction of malicious nodes by calculating the utility function. They control and adjust the game process and results through incentive mechanism. GBR (Game theory Based Routing algorithm) reduces packet loss rate by the above mechanisms and strategies and effectively controls the self-ish behavior of nodes. In addition, GBR pursues security routing and makes design and improvement in the energy conservation, which considers node security and regards the energy of the nodes as an importing reference index, in order to balance the network energy consumption.

    Abstract: Petrophysical property cutoff effective reservoir properties can be affected by reservoir properties, crude property, depth, formation temperature, formation pressure and other factors, among which reservoir properties, burial depth and formation temperature are the main factors in effective reservoir development degree of deep tight sandstone, formation pressure has a great impact on the effective reservoir development, while fluid properties have a relatively small impact. The development of oil production technology would reduce petrophysical property cutoff, which will lead to the transformation of non-effective reservoir earlier reckoned into effective reservoir in the future. Therefore, it is necessary in oil and gas exploration to continuously analyze lower limit of effective reservoir physical properties.

    Abstract: The content of ZrO 2 and TiO 2 in alkali-resistant fiberglass mesh was determined by ICP OES. The sample was pretreated by acid-soluble and alkali-fusion methods. Compared with the results of standard method, the results showed that the method can be used for the determination of ZrO 2 and TiO 2 in alkali-resistant fiberglass mesh. Standard solutions were prepared based on the content of elements. The best analysis of spectral lines was determined for each element. Blank solution was prepared and injected ten times continuously. The corresponding concentration of three times of standard deviation (3S) was used to calculate the detection limit of the method, and the detection limit was from 0.0018% to 0.0047%. The corresponding concentration of ten times of standard deviation (10S) was used to calculate the quantitation limit of the method, and the limit of quantitation was from 0.0060% to 0.016%. Six repeated tests were performed on two samples, and the relative standard deviations (RSDs (n=6)) of the test were from 0.60% to 0.78%. Compared to standard method, absolute error was less than 0.2% and the relative error was less than 2.0%. The results showed that the method can be used for simultaneous determination of ZrO 2 and TiO 2 in alkali-resistant fiberglass mesh., with fast analysis and reliable results.
