細分層壓裂 的英文怎麼說
中文拼音 [xìfēncéngyāliè]
細分層壓裂
英文
separate minilayer fracturing-
The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明,該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖;儲層巖石經歷了壓實,膠結,溶蝕等成巖作用,歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期( b亞期)膠結充填孔隙縮小期三個成巖-孔隙演化階段;儲層物性總體上具有較低孔滲、低孔滲的特點,孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔,裂縫不發育,儲集巖排驅壓力和中值壓力較高,孔隙結構類型以細小孔-微孔隙,微細喉-微喉型為主。Aiming at the abnormal strata behavior in the advance entry of 1303 fully - mechanized working face in xinglongzhuang coal mine, the movement rule, characteristic, step distance of fracturing, position and mode of fracturing of the overlying strata in mining process is analyzed by using the key strata theory
摘要針對興隆莊煤礦采區1303綜放工作面超前平巷發生奇異壓力的現象,採用關鍵層理論對在采動過程中的上覆巖層運動規律進行了詳細的力學分析,研究了它們的運動特徵、破斷步距、斷裂位置、斷裂方式以及對工作面及其超前平巷的來壓規律,對比分析了該工作面礦壓實測數據與理論研究成果。Aiming at characteristics of serious conflict among layers, thin layers developed and scattered distribution of remaining oil, this paper introduces techniques of non - gel fracturing, multi - fractures fracturing, large discharge capacity and large sand amount fracturing, thin layer fracturing and high effective return discharge
摘要針對大慶油田薩南開發區三類油層層間矛盾突出、油層發育薄及剩餘油分佈零散等特點,根據油藏精細地質研究成果,通過個性化壓裂設計,在試驗區三類油層聚驅挖潛過程中,應用了非凝膠壓裂、多裂縫壓裂、大排量及大砂量壓裂、薄隔層壓裂以及高效返排壓裂等配套的工藝技術。Adopting fracturing techniques of " deep - penetration 、 fine separate - layer and fast flowback ", which has attained a success rate as high as 99. 4 %, the effects of increasing oil productions are apparent
