Based on these and followed by proper reservoir classification and characteristics analysis,this paper established the methods for reservoir description of subtle pool with complex fault blocks,by which the main trap within the belt could be divided into fault block trap,structural trap and subtle trap which includes sand lens trap,lithologic updip thinning out trap,structural-lithologic trap and fault lithologic trap. For self-confined fault controlling oil flow,its height of oil column can be estimated by utilizing R.R.

在此基础上，通过油藏的具体分类和特征分析，建立了复杂断块隐蔽油藏的储集层和油藏描述方法；将东营凹陷中央隆起带中的主要油气藏划分为断块圈闭、构造圈闭和隐蔽圈闭，其中隐蔽圈闭包括砂岩透镜体圈闭、岩性上倾尖灭圈闭、构造-岩性圈闭、断层-岩性圈闭四类；提出在控油断层自密封的情况下，油藏高度可采用R.R。

She took part of our overseas on-location shooting sessions a couple times in the past 2 years. I found out this attractive lady likes to sneak around behind our backs and shoot with an electronic viewfinder digital camera while we were working. I dispatched her a Nikon D40x DSLR with a professional grade super wide-angle zoom lens on a recent trip to Mindoro and Palawan (both are provinces of the Philippine), even though she is not a photographic assistant to me. Moreover, that camera body I gave her was just becoming available and right out of the box at that time. Yes, brand new stuff!

在过去的2年间她参与了我们数次的出国外景摄影工作我发现每当我们开始上工忙碌时这位可爱的小姐喜欢偷偷地走在我们的后面神不知鬼不觉地用小DC侧拍因此在最近一次的中程旅行摄影队开跋到闵多洛和巴拉望纵使她的职责并不是我的摄影助理我给了她一台Nikon D40x DSLR机身跟一支专业用的超级广角变焦镜头还有我给她的那款照相机机身那时是刚上市而且是刚开箱是的全新的发烧货！
