【摘要】:海南3塊油氣主要分布在海南15-15塊~海南11井以北部位,約占海南3塊總儲(chǔ)量的74.6%。本文針對(duì)海南3塊的15-15斷塊,從三維地震精細(xì)解釋、儲(chǔ)層反演、地質(zhì)建模以及構(gòu)造、儲(chǔ)層、沉積相、剩余油分布等方面開展研究,具體研究?jī)?nèi)容如下:首先從水平井部署主力油層篩選;對(duì)主力油層油藏精細(xì)描述及地質(zhì)建模;主力油層剩余油分布規(guī)律研究;海南15-15塊水平井部署;對(duì)部署水平井進(jìn)行跟蹤調(diào)整等幾個(gè)方面開展研究,并且對(duì)油層油藏進(jìn)行精細(xì)描述,為三維地質(zhì)建模提供數(shù)據(jù)基礎(chǔ);利Petrel軟件,建立構(gòu)造建模、沉積微相建模及屬性建模,預(yù)測(cè)了井間物性參數(shù)的展布,其次,對(duì)15-15塊的開發(fā)階段進(jìn)行劃分,從不同階段入手對(duì)油田的產(chǎn)能特征,產(chǎn)量變化特征,見誰特征進(jìn)行了總結(jié)。在此基礎(chǔ)上,主要對(duì)注水見效類型及水驅(qū)儲(chǔ)量狀況,綜合含水及注水利用率,能量水平,油層動(dòng)用狀況,采油速度,加密效果,可采儲(chǔ)量等方面對(duì)油田開發(fā)方式、層系、井網(wǎng)井距適應(yīng)性進(jìn)行了一個(gè)綜合性的分析得出,本塊油層縱向分布較集中,井段不是很長(zhǎng),儲(chǔ)集條件、油藏類型相近,同時(shí)儲(chǔ)量豐度(300×104t/km2)比較低,不宜分層開采。油田實(shí)施的是300m的井距。在此井距下,砂體連通較好,連通系數(shù)83.6%,井距基本合理,同時(shí)開采中存在注采系統(tǒng)難以完善,層間矛盾突出等問題。最后,對(duì)海南3區(qū)塊水平井部署進(jìn)行優(yōu)化,通過分析,認(rèn)為油層動(dòng)用程度較低,仍有較大潛力,通過對(duì)油田開發(fā)經(jīng)濟(jì)性的綜合分析,按目前油價(jià)70美元/桶計(jì)算,靜態(tài)投資回收期為1.2年。通過對(duì)海南3塊水平井部署及跟蹤調(diào)整研究,可以指導(dǎo)這一區(qū)塊的水平井部署,今后的深化開發(fā),調(diào)整挖潛以及提高開發(fā)效果提供理論基礎(chǔ)。
[Abstract]:3 Hainan oil gas is mainly distributed in Hainan 15-15 ~ 11 wells of Hainan in the north part of Hainan accounts for about 3 of the total reserves of 74.6%. block in Hainan 3 block 15-15 block, from 3D seismic fine interpretation, reservoir inversion, geological modeling and reservoir structure, sedimentary facies, research on residual oil distribution so, the specific contents are as follows: firstly, the main reservoir horizontal well deployment of the main reservoir screening; reservoir description and geological modeling; remaining oil distribution of main reservoir; Hainan 15-15 horizontal well deployment; tracking adjustment research the whole aspects of the deployment of horizontal well, and fine description of reservoir. Provide the data base for 3D geological modeling; Petrel software, established the tectonic modeling, sedimentary microfacies modeling and property modeling, then predict the interwell physical parameters of the distribution, to divide the development stage 15-15, from Starting with the characteristics of oil production in different stages of the production change feature, see who features are summarized. On this basis, mainly on water flooding and water flooding type, water and water utilization, energy level, reservoir status, production rate, encryption effect, recoverable reserves of oil field development, layers, well spacing adaptability of a comprehensive analysis concluded that the reservoir vertical distribution is relatively concentrated, wells is not very long, reservoir conditions and reservoir types are similar, while the abundance of reserves (300 * 104t/km2) is relatively low, not layered mining. The implementation of the 300m oil well spacing this. Well spacing, sand body connectivity is better, connectivity coefficient 83.6%, well spacing is basically reasonable, while mining in injection production system to improve the problem, contradiction between layers. Finally, the Hainan block 3 horizontal wells deployment optimization, through analysis, recognition As the reservoir level is low, there is still great potential, through the comprehensive analysis of the economic development of oil field, according to the current price of $70 / barrel calculation, static investment payback period is 1.2 years. Based on Hainan 3 horizontal well deployment and adjustment research, can guide the block horizontal well deployment, development deepen the future, adjustment and provide a theoretical basis to improve the development effect.
