Evaluation of cap rock sealing capability of mudstone in dongpu depression by using compaction curve 應(yīng)用壓實曲線法評價東濮凹陷泥巖蓋層封閉能力
Therefore , it is urgent to study an advanced and convenient method obtaining maximum dry density in - situ . by means of data from kai - luo expressway , this paper established a mathematical model of compaction function by analyzing the characteristic of compaction curve 因此,迫切需要用快速、準確、方便的由現(xiàn)場干密度推算最大干密度的先進方法來逐步代替?zhèn)鹘y(tǒng)的標準擊實試驗。
The characteristics of compaction curves , the evolution of organic matter , the direction of migration and assignment , conduit system , fluid potential are studied it is concluded that the low maturity of the source of the eogene age is the main factor to control the entrapment . it controls the direction of the primary migration , confines the location of mature source rock and the special carrier rock , controls the time of expulsion and the amount of petroleum , therefore ; the effective traps should be near to oil kitchen and on the pathways of migration 認為下第三系油灶的低熟是影響其運聚成藏的關(guān)鍵因素,生油巖低熟決定油氣初次排烴的方向指向沙三下段;生油巖低熟決定成熟生油巖分布的局限性和輸導體的特殊性;生油巖低熟決定起排烴時間晚、生烴量不足,從而決定有效的圈閉應(yīng)是近源的、在運移主路線上。
A data processing technique for compaction curve is proposed from five inspected data to nine , or three data , and application program is developed for compaction curve . in " order to verify xgm method , author went to construction sites to inspect roadbed and collect field data . the optimum compaction curve , maximum dry density are obtained by means of data processing technique , which are good consistent with indoor standard compaction test 進而研究將5點法擴展為9個實驗點到3個實驗點的多層次優(yōu)化壓實曲線的數(shù)據(jù)處理法,提出了由現(xiàn)場干密度推算最大干密度的xgm相關(guān)干密度法,簡稱xgm法,開發(fā)出xgm法應(yīng)用軟件,繼而研究施工現(xiàn)場壓實檢測數(shù)據(jù)的優(yōu)化處理方法。
