摘要/Abstract

摘要： 叙利亚O油田SH_B油藏为典型的低渗孔隙型块状碳酸盐岩稠油油藏，因“低渗、油稠”等突出特点，在现行的井网和开采方式下油藏开发效果差，主要表现为“三低”，即储量动用程度低、单井产量低和油藏采收率低，尚无一套经济有效、可实施的开发方案。目前，低渗稠油油藏开发在国内外没有成功案例，也没有成熟技术及经验可借鉴，如何经济有效开发属世界级难题。为此，以“提高开发效益，实现有效开发”为目标，针对低渗稠油油藏面临的“三低”问题，应用油藏工程方法、数值模拟和经济评价技术，系统开展了开发方式、井型井网井距、水平段长度及水平井热采参数等优化研究，形成了低渗碳酸盐岩稠油油藏开发对策研究方法，针对性地提出了SH_B油藏的开发对策。优化确定的油藏开发技术对策为开发方案编制奠定了基础，也为国内外类似油藏开发提供了借鉴。

Abstract: Reservoir SH_B of O oilfield in Syria is atypical porous carbonate heavy oil reservoir with low-permeability.It strikingly features in low permeability and high viscosity.Under the present well patterns and development models,the development effect here is poor and it is manifested by three-low parameters:low ratio of produced reserves to proved reserves,low single well production and low recovery.No cost-effective and enforceable development plan has been proposed.Presently,there is no successful case on low-permeability heavy oil reservoir development and no mature technology and experience for reference.The development of this kind of reservoir is still a world-class challenge.In order to improve development benefits and realize effective development,reservoir engineering theories and methodologies,numerical simulation and economic evaluation techniques are used to study and optimize systematically the development models,well types,well patterns,well spacing,lateral length,and thermal recovery parameters of horizontal well.Research me-thods for developing carbonate heavy oil reservoir are suggested,and development strategy specifically for reservoir SH_B is proposed.The optimized development technical policy lays a foundation for development planning and provides a refe-rence for domestic and foreign analogous reservoirs.
