【摘要】：近年來,遼河油田面臨著有效勘探領(lǐng)域減小、勘探程度高、勘探目標(biāo)復(fù)雜的勘探形勢,擴大老區(qū)勘探領(lǐng)域迫在眉睫。經(jīng)過多年的持續(xù)勘探開發(fā),在S區(qū)塊沙四下段砂礫巖體已經(jīng)有多口工業(yè)油氣流井,勘探前景非常廣闊。為了擴大勘探成果,確定了在老區(qū)已有勘探成果基礎(chǔ)上向西斜坡北邊擴展到勘探思路。但是目前勘探中存在巖性認識不清、小層劃分困難、單井有效儲層難以劃分以及四性關(guān)系認識不清等問題。2015年已經(jīng)初步建立了S區(qū)塊沙四下段砂礫巖體巖性識別、儲層劃分標(biāo)準(zhǔn)、參數(shù)計算模型和儲層工程品質(zhì)計算模型,為研究工作打下了堅實基礎(chǔ)。本文應(yīng)用測井的手段,在巖心聯(lián)合描述及巖礦實驗的基礎(chǔ)上,充分利用已鉆探井資料,開展巖性二次解釋,對單井巖性進行重新劃分;此外在巖性二次解釋的基礎(chǔ)上,綜合試油、試采、錄井及其它地質(zhì)資料,對儲層進行二次解釋、儲層參數(shù)研究、測井相的劃分及儲層工程品質(zhì)研究,為整個勘探提供技術(shù)支持。
[Abstract]:In recent years, Liaohe Oilfield is faced with the exploration situation of decreasing effective exploration field, high exploration degree and complex exploration target. It is urgent to expand the exploration field in old area. There are already many industrial oil gas flow wells in the sand gravel rock of the fourth member of S block, and the prospect of exploration is very broad. In order to expand the exploration results, It is determined that the exploration idea is extended to the north of the western slope on the basis of the existing exploration results in the old area. However, at present, there is a lack of clear understanding of lithology in exploration, and it is difficult to divide small beds. In 2015, the lithology identification, reservoir classification standard, parameter calculation model and reservoir engineering quality calculation model of the sand-gravel rock mass in the lower member of Sha-4 formation in S block have been preliminarily established. In this paper, based on the core joint description and rock and mineral experiments, the lithology secondary interpretation is carried out, and the lithology of single well is reclassified by using the data of drilling wells. In addition, on the basis of secondary interpretation of lithology, combined with oil test, production test, logging and other geological data, the secondary interpretation of reservoir, the study of reservoir parameters, the division of logging facies and the study of reservoir engineering quality provide technical support for the whole exploration.
