【摘要】：姬塬油田始探于1970年,2003年以來,在三疊系延長組中下部油藏勘探獲得較大突破。本次研究在收集的地質(zhì)材料、巖心資料、測井資料、生產(chǎn)動態(tài)資料和前人研究成果的基礎(chǔ)上,對該區(qū)長9油層組進(jìn)行了系統(tǒng)的地層劃分與對比,沉積微相研究,測井資料解釋,儲層特征等方面的研究,得到了以下結(jié)論:(1)研究區(qū)長9油層組為三角洲平原沉積體系,物源方向主要來自于東北和西北,長911、長912、長 921、長 922四個小層的砂體展布嚴(yán)格受沉積相控制;(2)研究區(qū)長9儲層主要以長石巖屑砂巖、巖屑長石砂巖和長石砂巖為主,碎屑成分主要以石英類和長石類為主。砂巖粒度以細(xì)為主,分選差,磨圓度中等。有微小孔隙發(fā)育,孔隙結(jié)構(gòu)復(fù)雜。根據(jù)儲層特征,建立統(tǒng)一標(biāo)準(zhǔn)將儲層分為四類。主要以II、III類為主;(3)利用試油和生產(chǎn)動態(tài)信息,提取與產(chǎn)能相關(guān)的多種參數(shù)分別與試油產(chǎn)量、生產(chǎn)產(chǎn)量進(jìn)行相關(guān)性分析。采用產(chǎn)能系數(shù)法,有效厚度和含油飽和度乘積法預(yù)測產(chǎn)量,乘積法效果較好;(4)預(yù)測有利區(qū)17個,1個III類可擴(kuò)邊區(qū)。預(yù)測有利區(qū)面積長921面積32.95 km2,長912面積32.82 km2,長911面積185.12 km2。為姬塬油田今后的開發(fā)提供地質(zhì)依據(jù)。
[Abstract]:Jiyuan Oilfield was first explored in 1970 and since 2003, it has made a great breakthrough in the exploration of middle and lower reservoirs of the Yanchang formation of Triassic. On the basis of the geological materials, core data, logging data, production performance data and previous research results, the formation of Chang 9 reservoir in this area has been systematically divided and correlated, sedimentary microfacies studied and log data interpreted. The main conclusions are as follows: (1) the Chang 9 formation in the study area is a delta plain sedimentary system, and the source direction is mainly from northeast and northwest. The distribution of sand bodies in Chang 911, Chang 912, Chang 921 and Chang 922 layers is strictly controlled by sedimentary facies. (2) Chang9 reservoir in the study area is mainly composed of feldspathic sandstone, lithic feldspathic sandstone and feldspathic sandstone, and the main clastic components are quartz and feldspar. Sandstone granularity is mainly fine, sorting is poor, grinding roundness is medium. Tiny pores develop and pore structure is complex. According to the reservoir characteristics, a unified standard is established to divide the reservoir into four categories. (3) based on the information of oil test and production dynamics, a variety of parameters related to production capacity were extracted, respectively, and the correlation analysis was carried out with the oil test output and production yield. The productivity coefficient method, effective thickness and oil saturation product method are used to predict production, and the product method is effective. (4) 17 favorable regions and 1 III extensible border area are predicted. The area of favorable area is 32.95 km ~ 2, area of 912 is 32.82 km ~ 2, and area of 9 / 11 is 185.12 km ~ 2. It provides geological basis for future development of Jiyuan oilfield.
