【摘要】：黃金帶油田是遼河油田的一部分,發(fā)育在受斷裂控制的遼河盆地的東部凹陷內(nèi),斷塊復(fù)雜,砂體厚度薄、平面連通性差,這些都對(duì)油田的整體認(rèn)識(shí)造成了困難。而且經(jīng)過(guò)幾十年的勘探開(kāi)發(fā),油田主力儲(chǔ)層的油氣已經(jīng)大量采出。為維持老油田的持續(xù)穩(wěn)產(chǎn),本次研究對(duì)黃金帶油田進(jìn)行了儲(chǔ)層四性關(guān)系、儲(chǔ)層測(cè)井二次解釋、小層級(jí)別的氣、油、水分布規(guī)律進(jìn)行研究,從而尋找剩余油有利地區(qū)。研究結(jié)果表明,黃金油田沙河街組一段油層的巖性、物性、含油性和電性具有較一致的變化規(guī)律,即巖性越粗、物性越好、含油越飽滿(mǎn)、電性越好。含油級(jí)別下限定為油斑;含油的巖性下限定為細(xì)砂巖級(jí);含油的孔隙度下限定為11%,對(duì)應(yīng)的滲透率下限為10×10-3μm2;電性的含油下限定為電阻率10Ω·m,聲波時(shí)差270μs/m。油氣分布主要受工區(qū)內(nèi)復(fù)雜的斷塊和沉積相帶的控制,同時(shí)也受儲(chǔ)層巖性和物性條件影響,因此工區(qū)內(nèi)W閉多為構(gòu)造和巖性共同控制的復(fù)合型油氣藏。油氣主要在主體構(gòu)造高部位以及北東—南西走向的斷裂帶所控制的條帶狀區(qū)域分布。每個(gè)小層中油氣分散較為分散,自下而上油層發(fā)育變差,氣層發(fā)育變好。剩余油則集中在構(gòu)造較高、斷層遮擋、物性相對(duì)較差及注采不完善、儲(chǔ)層未動(dòng)用部位�？v向上各小層儲(chǔ)量動(dòng)用不均衡,分層采出程度差異大,剩余可采儲(chǔ)量縱向上不集中,主力層不明顯,挖潛難度大。S1上主力層位采出程度高,地質(zhì)儲(chǔ)量也較少,剩余可采儲(chǔ)量主要S1中和S1下段位置。
[Abstract]:The gold-belt oil field is a part of Liaohe oilfield, developed in the eastern sag of Liaohe basin controlled by fault. The fault block is complicated, the thickness of sand body is thin, and the plane connectivity is poor. After decades of exploration and development, oil and gas in the main reservoir has been produced in large quantities. In order to maintain the sustained and stable production of the old oil field, this study has carried on the reservoir four relations to the gold belt oil field, the reservoir logging secondary interpretation, the small layer grade gas, the oil, the water distribution law carries on the research, thus seeks the remaining oil advantageous area. The results show that the lithology, physical property, oil-bearing property and electrical property of the first member of Shahejie formation in gold oil field have the same change rule, that is, the thicker the lithology, the better the physical property, the fuller the oil content and the better the electric property. The oil level is limited to oil patch; the lithology of oil is limited to fine sandstone; the porosity of oil is limited to 11 and the lower limit of permeability is 10 脳 10 ~ (-3) 渭 m ~ (2); the resistivity of oil is limited to 10 惟 m, and the acoustic time difference is 270 渭 s / m ~ (-1). The distribution of oil and gas is mainly controlled by the complex fault blocks and sedimentary facies belts in the working area, and also by the lithology and physical conditions of the reservoir. Therefore, the W / W closure in the working area is mainly a composite oil and gas reservoir controlled by structure and lithology together. The distribution of oil and gas is mainly in the high part of the main structure and the belt area controlled by the fault zone of NSE-NW strike. The distribution of oil and gas in each sublayer is relatively dispersed, and the development of the bottom-up reservoir becomes worse and the gas reservoir develops better. The remaining oil is concentrated in high structure, fault occlusion, relatively poor physical properties, imperfect injection and production, and unused reservoir. On the vertical level, the production of reserves is unbalanced, the degree of stratified recovery is different, the remaining recoverable reserves are not concentrated vertically, the main layer is not obvious, and it is difficult to tap potential. The remaining recoverable reserves are mainly located in the lower part of S1 and S1.
