摘要:
莺歌海盆地是我国南海北部海域重要的高温超压含油气盆地,近年来在该地区已取得诸多高温超压勘探成果和气田发现,但是乐东斜坡带高温超压天然气的储集体预测和运移通道与盖层评价仍存在较大困难。“十三五”以来,综合地震、测井、录井、测试等资料,系统地开展了莺歌海盆地成盆构造与深水砂岩沉积过程的研究,建立了盆央海底扇和轴向水道等深水砂岩沉积模式和分布预测方法; 通过运移通道和盖层评价等成藏条件的研究,建立了“早期走滑破裂+晚期超压活化”天然气富集新模式和基于水力破裂压力系数计算的不同成藏体系盖层定量评价方法; 同时创新形成了两项勘探关键技术,即非欠压实地层孔隙压力预测技术和中深层非亮点储层综合预测技术,解决了高温超压条件下的非欠压实地层孔隙压力预测和非亮点储层预测难题,促进了乐东斜坡带大中型气田的发现。
Abstract:
The Yinggehai Basin is an important high temperature and overpressure oil-bearing basin in the northern part of South China Sea. In recent years, although abundant high-temperature and overpressure exploration results and gas field discoveries have been achieved in this area, there are still major difficulties in the high-temperature and overpressure reservoir bodies prediction as well as the migration channels/caprocks evaluation in the Ledong slope belt. Since the “13th Five-Year Plan” period, based on the comprehensive seismic, logging, mud logging, and testing data, systematical researches on the basin-forming structures and deepwater sandstone sedimentation processes in the Yinggehai Basin have been carried out, and the depositional model and distribution prediction method for the deepwater sandstones such as central basin submarine fans and axial channels have been established; through studying and evaluating the accumulation conditions such as migration channels and caprocks, a new model of natural gas enrichment based on “early strike-slip rupture+late overpressure activation” and the hydraulic fracture pressure coefficient calculation-based caprocks quantitative evaluation method are established for different accumulation systems; at the same time, two key exploration technologies have been innovated, namely the pore pressure prediction technology for non-undercompacted strata and the comprehensive prediction technology for mid-deep non-bright spot reservoirs, which has addressed the challenges in predicting those strata and reservoirs under high temperature and overpressure conditions, and promoted the discovery of large-medium scale gas fields in the Ledong slope belt.
