油水边界

利用地震多参数预测油水边界

Prediction of oil-water boundary by means of seismic multiparameter analysis

此法用于A油田的检测，获得了成功，使该区多年未查明的油水边界问题得到了很好的解决。

The method was used for detection of A oilfield and gained success , better solved the problem of undefined oil-water boundary many years ago in the area .

通过综合考虑气液边界传质阻力、油水边界乳化剂形成的液膜边界层阻力、PUFA自催化氧化反应动力学，建立了相应的扩散-氧化数学模型。

By considering the mass transfer resistance of gas-liquid boundary , the resistance of boundary layer from emulsifier membrane and the autocatalytic-type autoxidation reaction of PUFA compositely , a mathematical model of diffusion-oxidation was established .

通过研究，重新认识本块油水边界，滚动部署了5口井，投产4口井，初期日增油44吨，累增油4.2×104t。

By study , restudy the oil-water contact , roll - deploy 5 wells , 4 are put into production , add 44 tons per day at the initial stages , accumulate adding oil for 420 thousands tons .

油水边界水侵严重的井点等。

油水边界研究，确定含油面积；

Determination of oil-water contact is to draw the boundary of oil-existing area ;

由于在蒸汽吞吐开发过程中要受到多种因素的影响，而且生产井处于断层和油水边界附近，所以层间水复杂小断块稠油油藏的开发难度较大。

Effected by many factors during huff and puff , the reservoir of edge water invasion and complex small fault block , the producing wells which are located in the neighborhood of the fault trace and oil-water contact , are quite difficult for development .

油藏边界主要包括油水界面、岩性边界和断层边界等。

The reservoir boundary includes oil-water contact , lithologic boundary and fault limit .
