【摘要】：英東油田一號(hào)構(gòu)造是2010年發(fā)現(xiàn)的一個(gè)新油田，該油田類型為多斷塊背斜油氣田，油田儲(chǔ)層埋藏淺，油層跨度大。研究區(qū)斷層情況復(fù)雜，鉆井鉆遇率低，后期分層系開發(fā)井位部署優(yōu)化困難，這些嚴(yán)重影響著油田的增儲(chǔ)上產(chǎn)。同時(shí)，保證油田早日實(shí)現(xiàn)分層系開發(fā)和油田開發(fā)最大經(jīng)濟(jì)效益化，急需開展油砂體的精細(xì)解釋，摸清油砂體分布情況，，以達(dá)到科學(xué)合理開發(fā)為目的。 本論文研究是在前人研究的基礎(chǔ)上，充分利用現(xiàn)有的鉆錄井、測井、試油試采資料，運(yùn)用精細(xì)地層對(duì)比技術(shù)，厘定油層組劃分的標(biāo)準(zhǔn)，確定標(biāo)志層的位置和油層組層數(shù)。通過重點(diǎn)井的沉積相標(biāo)志和粒度深入研究，還原沉積環(huán)境，以及建立測井相與沉積相之間的轉(zhuǎn)化關(guān)系，劃分出上油砂山組為辮狀河三角洲前緣亞相，砂體以水下分流河道為主，下油砂山組為三角洲前緣及淺濱湖交互沉積，砂體以灘壩為主。另外，建立了油砂層測井四性關(guān)系和各參數(shù)模型，確定了儲(chǔ)層巖性、物性、含油性和電性特征。在此基礎(chǔ)上，分?jǐn)鄩K進(jìn)行砂體分布與油砂體分布研究，提出有利油砂體的分布區(qū)域與影響油砂體展布的主控因素，為油田后期分層系開發(fā)提供理論依據(jù)。
[Abstract]:The No. 1 structure of Yingdong Oilfield is a new oilfield discovered in 2010. The type of oilfield is multi-fault block anticline oil and gas field. The reservoir is shallow buried and the reservoir span is large. The complex fault situation, low drilling rate and difficulty in optimizing the location of stratified development wells in the later stage of the study area seriously affect the increase of reservoir and production in oil fields. At the same time, it is urgent to carry out fine interpretation of oil sand body and to find out the distribution of oil sand body in order to achieve scientific and reasonable development in order to ensure the development of stratified system and the maximum economic benefit of oilfield development as soon as possible. On the basis of previous studies, this paper makes full use of existing logging, logging and production test data, and applies fine formation correlation technology to determine the criteria for the division of reservoir groups, and to determine the location of marked layers and the number of reservoir formations. Through in-depth study of sedimentary facies marker and grain size of key wells, reduction of sedimentary environment and establishment of transformation relationship between logging facies and sedimentary facies, the upper oil sand mountain formation is classified as braided river delta front subfacies, and the sand body is dominated by underwater distributary channel. The Lower Yeshan formation is the delta front and shallow lake interactive deposition, and the sand body is dominated by beach and dam. In addition, the relationship between four properties of oil sand reservoir logging and each parameter model are established, and the lithologic, physical, oil bearing and electrical characteristics of reservoir are determined. On the basis of this, the distribution of sand body and oil sand body in fault block is studied, and the distribution area of oil sand body and the main controlling factors influencing the distribution of oil sand body are put forward, which provides the theoretical basis for the development of stratified system in the later stage of oilfield.
