【摘要】：海南3块油气主要分布在海南15-15块~海南11井以北部位,约占海南3块总储量的74.6%。本文针对海南3块的15-15断块,从三维地震精细解释、储层反演、地质建模以及构造、储层、沉积相、剩余油分布等方面开展研究,具体研究内容如下:首先从水平井部署主力油层筛选;对主力油层油藏精细描述及地质建模;主力油层剩余油分布规律研究;海南15-15块水平井部署;对部署水平井进行跟踪调整等几个方面开展研究,并且对油层油藏进行精细描述,为三维地质建模提供数据基础;利Petrel软件,建立构造建模、沉积微相建模及属性建模,预测了井间物性参数的展布,其次,对15-15块的开发阶段进行划分,从不同阶段入手对油田的产能特征,产量变化特征,见谁特征进行了总结。在此基础上,主要对注水见效类型及水驱储量状况,综合含水及注水利用率,能量水平,油层动用状况,采油速度,加密效果,可采储量等方面对油田开发方式、层系、井网井距适应性进行了一个综合性的分析得出,本块油层纵向分布较集中,井段不是很长,储集条件、油藏类型相近,同时储量丰度(300×104t/km2)比较低,不宜分层开采。油田实施的是300m的井距。在此井距下,砂体连通较好,连通系数83.6%,井距基本合理,同时开采中存在注采系统难以完善,层间矛盾突出等问题。最后,对海南3区块水平井部署进行优化,通过分析,认为油层动用程度较低,仍有较大潜力,通过对油田开发经济性的综合分析,按目前油价70美元/桶计算,静态投资回收期为1.2年。通过对海南3块水平井部署及跟踪调整研究,可以指导这一区块的水平井部署,今后的深化开发,调整挖潜以及提高开发效果提供理论基础。
[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.
