tight fracture 中文意思是什麼
tight fracture
解釋
閉合裂縫-
Based on 3 - d seismic well and logging data, mainly by means of advanced seismic theories of reservoirs prediction and other corelational multidisciplinary, an extensive and indepth studying on the tight sandstone reservoir with fracture of the second part of the xujiahe formation in west sichuan depression has been carried out. a series of theoretical viewpoints and research fruition are concluded as follows :. 1 on the basis of analysis of the regional and local structure characteristics and evolution, a conclusion comes in to being : inchoate and nowadays structure traps and the match model between structure and fracturation system are the main factors in controlling the formation of effective traps
本文綜合利用三維地震、鉆井、巖心、測井資料，採用地震儲層預測方法為主線的多學科綜合研究思路對川西坳陷上三疊統須家河組二段緻密裂縫性砂巖儲層進行了較為廣泛、深入的研究和探索，取得以下一系列理論認識和研究成果： 1 、通過區域及局部構造特徵及構造演化史分析，認為古今構造圈閉、構造與斷裂系統配置關系是控制有效圈閉形成的主要因素。 -
4 on the basis of identifying favorable logging faces to recognize effective reservoirs and studying the reservoirs " charateristics in logging and seismic data ; the model of the reservoirs " seismic response is established. according to the research, the pointed geophysics methods to detect gas in tight reservoir with fracture are made out
4 、運用測井聚類分析技術進行測井相分類，識別有效儲層；研究儲層含氣測井、地震響應特徵，建立儲層含氣地震響應模式，提出了針對性較強的緻密裂縫性砂巖儲層地震含氣性檢測方法。 -
3 after analysed the deformation of the structures and fractures, predicted 2 - d fractural degree through the study of natural fracture net, indentified and evaluated fracture though logging data, analysed 3 - d seismic coherence data > counted the dip angle " s of strata etc, the distribution of fracture is pointed out, the prediction methods which combined with geological and geophysical technologies of the fractural zones in the tight sandstone is also presented
3通過構造及斷裂形變分析、天然裂縫網路二維裂縫度預測、測井裂縫識別與評價、地震三維相干分析、地層傾角計算等預測裂縫分佈區，提出地質裂縫預測技術和地球物理裂縫預測技術相結合的緻密砂巖儲層裂縫發育帶預測方法。 -
Abstract : a number of comprehensive study data of cores, structures, inclusions, well - testing performance and fracture pressure gradient have shown that there are several fracture types in the jurassic tight sandstone reserviors of western sichuan basin, such as local structures, subtraction ( load relieving ), stratification and corrosion etc. the leading origin type of fracture is the paleo - subtractive one formed by uplifting subtraction during geohistorical process, which is the main percolation passage in the process of oil / gas concentration, reservoiring and production
文摘:川西侏羅系緻密砂巖儲層中，存在局部構造、卸載、層理及溶蝕等數種裂縫類型，而由地史過程中的隆升卸載作用形成的古卸載裂縫是主導裂縫，也是油氣富集、成藏及產出過程中的主要滲濾通道。
