【摘要】：海洋石油勘探开发经过近40年的发展,近海整装大中型油气田的勘探难度不断增大,为保证产能接替和国家能源安全,越来越多的中小型构造岩性油藏被陆续发现和投入开发。W油田北块位于南海北部湾盆地北部涠西南凹陷,构造内断层发育,东西两翼岩性尖灭,为构造岩性复合油藏。探明含油面积6.56km2、地质储量1683.63×104m3;主要储层发育于古近系流沙港组流一段,纵向上分为5个油组。油藏天然能量匮乏,为合理注水开发,本文以储层沉积学、油藏开发地质学、油藏工程等多学科为指导,综合地震和测井解释、试油试采、取心和化验分析等资料,研究南海w油田北块的地质构造特征、储层沉积相、油藏特证,开展油层划分和对比、明确油藏类型和地质储量。运用油藏工程方法,研究确定海上构造岩性油藏最优注水开发技术政策,结合油藏地质建模和数值模拟研究,经过开发敏感性参数分析优化比选,针对南海W油田北块提出合理注水开发技术和开发方案,对海上相似油藏的后续开发具有重要借鉴意义。
[Abstract]:After nearly 40 years of development of offshore oil exploration and development, the exploration difficulty of offshore assembled large and medium-sized oil and gas fields is increasing. In order to ensure the replacement of production capacity and national energy security, More and more small and medium-sized structural lithologic reservoirs have been discovered and put into development. The north block of .W oil field is located in the Wei Southwest sag in the northern part of Beibu Gulf basin in the South China Sea. The internal faults of the structure are developed, and the lithologic pinnacle of the east and west wings is destroyed. In order to construct lithologic composite reservoir, the proved oil area is 6.56 km ~ 2 and geological reserves is 1683.63 脳 10 ~ 4 m ~ 3. The main reservoir is developed in the flow section of the Paleogene Liushagang formation and is divided into five oil groups vertically. The natural energy of the reservoir is scarce, so the reservoir is developed by reservoir sedimentology. Under the guidance of various disciplines such as reservoir development geology, reservoir engineering, comprehensive seismic and logging interpretation, oil testing and production testing, coring and laboratory analysis, the geological structure characteristics, reservoir sedimentary facies, reservoir characteristics and reservoir characteristics of the North Block of South China Sea W Oilfield are studied. Developing reservoir division and correlation, defining reservoir types and geological reserves, using reservoir engineering methods, studying and determining optimal water injection development technology policy for offshore structural lithologic reservoirs, combining with reservoir geological modeling and numerical simulation research, Through the analysis and optimization of development sensitivity parameters, reasonable water injection development technology and development scheme are put forward for the North Block of South China Sea W Oilfield, which is of great significance for further development of similar offshore reservoirs.
