Distribution and accumulation of hydrocarbon in jigesen structural zone 吉格森構(gòu)造帶油氣分布與聚集規(guī)律
The non - linear optimum inversion technique has achieved a fine result in predicting the distribution of the oil - bearing formation of permo - caboniferous in the south hexiwu structural zone , and provided the important data for promoting the rolling exploration in the district 應(yīng)用非線性最優(yōu)化反演技術(shù)預(yù)測河西務(wù)南部石炭二疊系的含油儲層分布取得了良好的效果,為本區(qū)滾動勘探的突破提供了有力的決策依據(jù)。
According to the oil occurrence and evaluation on traps in various structural zones , in combining with practice of oil exploration in recent years , two targets for further intense exploration , three targets for further evaluation and three targets for primary exploration have been chosen 根據(jù)原油分布特征和區(qū)帶圈閉含油性綜合評價結(jié)合近年勘探成果,確定近期勘探部署為: “滾動兩個目標(biāo),評價三個目標(biāo),預(yù)探三個目標(biāo)”
Ultramafic rock fragments , which almost is altered to ophite , distributed in structural zone and displayed structural lens . so far , 9 fragments were discovered and mapped in nujinshan and bujing area ultramafic rock can be divided two kinds according to it ' s geochemical characteristics . one can be correlated with metaperidotite , which represented residual part that primary pyrolite underwent moderate partial melting , from some representative ophiolite melange in the world 按超鎂鐵巖類的地球化學(xué)特征可將其劃分為兩類:一類具有較高而穩(wěn)定的mgo 、較低的al _ 2o _ 3 、極低的cao , m f值為8 . 0 ? 8 . 4 ,按標(biāo)準礦物組合進行分類可定為方輝橄欖巖,且均為fa _ ( 100 ) 、 en _ ( 100 )的鎂質(zhì)端元組分;可與世界上一些典型的蛇綠巖套中變質(zhì)橄欖巖進行對比,代表了原始地幔中等部分熔融作用后殘余物。
Based on it , favorable exploration areas in wuerxun depression are predicted . the most favorable exploration areas of ktn2 are surennuoer structural zone and huangqimiao structural zone . the more favorable exploration areas are tongbomiao structural zone , wudong slope zone , wuxi fault zone , vvuzhong structural zone and bayantala structural zone . huang yi - l , suwu - 7 and suba - 9 traps ofk1p2 are considered to be the most favorable traps for oil or gas to be drilled 在綜合上述研究的基礎(chǔ)上,對烏爾遜凹陷南二段的有利勘探區(qū)進行了預(yù)測,指出蘇仁諾爾斷裂構(gòu)造帶、黃旗廟斷裂構(gòu)造帶南部為有利勘探區(qū),銅缽廟構(gòu)造帶、烏東斜坡帶、烏西斷裂帶、烏中構(gòu)造帶和巴彥塔拉構(gòu)造帶為較有利勘探區(qū),南二段黃? - 1 、蘇五- 7 、蘇八- 9圈閉是烏爾遜凹陷南二段油氣下一步勘探的有利靶區(qū)。
