CB 油田为复杂断块、断鼻型圈闭油藏,地面河网发育,地下构造复杂。为了科学、高效地滚动开发该油田,充分利用构造精细解释技术,对该区层位和断层进行准确标定和解释,为CB 油田滚动开发提供了准确的地下构造模型,一次性部署了井网,节约了大量投资,同时,在滚动开发中,使该区的含油面积和地质储量不断增加。

CB Oilfield is a complex fault - block and fault nose trap reservoir , there are lots of rivers on the ground , and the underground structure is very complex. In order to develop the oilfield scientifically and high efficiently , horizons and faults in the area were accurately demarcated and interpreted by making full use of fine structure interpretation technologies ,offering the precision structure modle under the ground. In progressive expolaration and development of CB Oilfield ,the well pattern is disposed as batch ,productive investment can be retrenched ,and area of oil-bearing and geology reserves continually increased.
