The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j. r. l. allen ; gets a group of parameters including the reservoir thickness, porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is x h, kxh and h / h, and accounts the favorable region. on the base of above - mentioned studies, the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field
Allen ）等人提出的統計方法，用垂向上砂體密度的界限來推測砂體側向連通情況；根據每口井的測井解釋資料，利用克里金插值法對外間進行插值，得到了一組反映儲層特徵在平面上變化的參數，包括儲層厚度分佈、孔隙度以及滲透率，並且成圖；利用變差函數法，通過球狀函數模擬，確定儲層優勢滲透率方向：根據流動單元法，以儲能系數、容積系數以及凈毛厚度比三個參數為依據，通過聚類分析方法進行流動單元劃分，並且按照參數特徵將其分為五類，統計各砂層有利流動單元區塊。 -
The research on blanking zone shows that the variation hydrate saturation is altering with porosity in the blanking zone
對空白帶的研究則表明在空白帶中水合物的飽和度是隨孔隙度變化的。 -
The keep - up pressure recovery of most oil - gas reservoirs and the gas storage measurement on some depletion reservoirs have been made in china, which have endlessly caused variation of pressure difference between inside - pore and outside - pore, followed by always changes of compressibility, porosity and permeability of rocks due to injection and production time and again of reservoir fluids
摘要目前我國許多油氣藏進行了保壓開采措施及對部分衰竭油氣藏進行儲氣庫改造措施，油氣藏流體反復注采，使得孔隙內外壓差不斷變化，導致巖石壓縮系數、孔隙度、滲透率發生著不斷的變化。 -
3 ) the sandbody distribution, physical properties, pore structure and heterogeneities are affected by the microfacies. at the center part of underwater distributive river course, the petrophysics and physical properties are both better than that at the edge of the microface. 4 ) the chang 61 2 - 3 substrata and the substrata of chang 62 " member which show the better porosity, permeability, and better pore structure ; display lower permeability variation coefficient, dart - coefficient and contrast - coefficient and good connecting sandbody so the horizontal heterogeneities is weaker ; whereas manifest stronger inner - heterogeneities due to the numerous intermediates ; present stronger inter - heterogeneities caused by the greater frequency of sandbody
長6儲層中長6 _ 2 ~ （ 1 - 3 ）和長6 _ 2 ~ 1砂層中的各個小層的孔隙度、滲透率值、含油性較好；平面非均質性較弱，表現為級差、突進系數、變異系數較低且砂體的連片程度高，鉆遇率和連通系數較高；與此同時，層內非均質性較強，表現為垂向上夾層的數目較多，厚度較大；層間非均質性也較強表現為分層系數較高。 -
The physical and chemical properties of the soil were analyzed, including nutrient change and routine index of acidity and alkalinity, in addition, compared them with natural soil and studied their variation and correlation. the results as follows : the soil bulk density of harbin urban vegetation is higher, total porosity and field capacity are small
對其土壤的理化性質和養分狀況等指標進行分析，並與松花江地區自然黑土進行了對比，研究其變化的趨勢和養分相關性。結果表明：哈爾濱城市綠地土壤容重較大，孔隙度和田間持水量少，有機質缺乏，養分含量較低，相關性差，土壤ph值呈中性，肥力水平低。 -
It is related to lithology, lithology association porosity, permeability, compressibility of rock, enclosing and fracture etc. therefore, it is important for the forecast of formation compression to consider fully the variation of each geology factor
實際上，地層壓力的影響因素很復雜，與巖性及其組合、巖石的孔隙度及滲透率、壓縮性、巖層的封閉性、裂縫等有關。因此，在進行地層壓力預測時要充分考慮各種地質因素的變化。
