Characteristics of evolution and distribution of lithologic trap in dongying delta , shengli oilfield 東營三角洲演化特征與巖性圈閉分布規(guī)律
The lithologic traps can be further divided into two types , i . e . primary and secondary lithologic traps , according to forming mechanisms 根據(jù)形成機(jī)理,將其巖性圈閉進(jìn)一步劃分為原生和次生兩種類型。
Early generation of lithologic traps coupled with early hydrocarbon charges make the early formation of oil accumulation possible 巖性圈閉形成的早期性和巖性油藏的相對早期充注可能是產(chǎn)生巖性油藏相對早期形成的主要因素。
The gas pools exploited in shengli oilfield mainly belong to lithologic traps controlled by fractures and lithology , with closed and size - restricted water 摘要?jiǎng)倮蛥^(qū)目前投入開發(fā)的氣藏大多數(shù)屬于構(gòu)造背景上的巖性氣藏,受斷層及巖性的控制,水體是封閉的,其大小是有限的。
The non - structural gas reservoirs in ordos basin can be divided into 4 types , such as a reservoir of lithologic trap of sandstone lens , lithologic trap of differential diagenesis , overlying lithologic - formation trap and the reservoir related with weathering and uncomformity surface 摘要鄂爾多斯盆地非構(gòu)造氣藏可分為4類:砂巖透鏡體巖性圈閉、差異成巖作用形成的巖性圈閉、上傾巖性地層圈閉、與風(fēng)化殼和不整合面有關(guān)的巖性地層圈閉氣藏。
J22 well area geology condition is superior , forward modeling , earthquake attribute analysis , seismic phase analysis , wave impedance inversion are applying to the qualitative analysis and the rational description to the sand three center 3 granulated substance groups reservoir on the basis of the achievement of utilizing geology , well logging and mud logging combined with fine structure research , advantageous belt of the development of lithologic trap has been pointed out and the very good effect of detecting the position of exploration well has been obtained 摘要j22井區(qū)地質(zhì)條件優(yōu)越,在充分利用地質(zhì)、測井、錄井等成果的基礎(chǔ)上,應(yīng)用模型正演、地震屬性分析、地震相分析、波阻抗反演、三維可視化等技術(shù),對沙三中3砂組儲層進(jìn)行了定性分析和定量描述,結(jié)合精細(xì)構(gòu)造研究,指出了構(gòu)造巖性圈閉發(fā)育的有利區(qū)帶,落實(shí)了勘探井位,取得了很好的效果。
On the basis of analyzing and chemically examining a large numble of samples , through comprehensively studying the reservoiring geological conditions as hydrocarbon generation , petrophysical property , reservoir - caprock assemblage and lithologic trap type , by use of mathematical statistics , it was considered that yulin gas field is located in the greatest hydrocarbon - generating intensity area in the basin and its hydrocarbon source rocks are the permo - carboniferous coal measure strata , thus possessing the material conditions of forming large - sized gas fields 通過大量的化驗(yàn)分析樣品數(shù)據(jù),采用數(shù)理統(tǒng)計(jì)的方法對生烴條件、儲層物性、儲蓋組合配置、巖性圈閉類型等成藏地質(zhì)條件進(jìn)行了較為深入的研究,認(rèn)為榆林氣田處于鄂爾多斯盆地最大生烴強(qiáng)度區(qū),其烴源巖為石炭二疊系煤系地層,具備形成大型氣田的物質(zhì)條件。
The most favorable reservoirs of study formatioms in study area are delta river mouth bar sand body and sublacustrine fan sand body . the sublacustrine fan sand body region developed in each sand group and the river mouth bar sand body region developed in gao 5 sand - group are the most favorable regions of developing lithologic traps 研究區(qū)研究層段的最有利儲層是三角洲河口壩砂體和湖底扇砂體,各砂組發(fā)育的湖底扇砂體區(qū)和高5砂組發(fā)育的河口壩砂體發(fā)育區(qū)是形成巖性圈閉最有利的場所。
