First , on the base of the analysis of history cost data , it divides the operating cost into the relative variable cost and the relative fixed cost 首先,在整理、分析油田历史成本数据的基础上,对单井的操作成本重新界定,划分为相对变动成本和相对固定成本两大类。
The study results provide theoretical basis for selecting reasonable horizontal completions , improving single completion productivity , and maximizing reservoir potential 该研究结果为水平井选择合理的完井方式，提高单井产能，最大限度地开发储层潜能提供了理论依据。
It confirms five classes of remains distributing mode , including micro - class , single - well and singe - layer class , inter - well and single - layer class , interlayer class and plane class 确定了五个级次的剩馀油分布模式，包括微观级、单井单层级、井间单层级、层间级和平面级。
By analyzing the production test data , we get the index production equation , bi nomial production , production degression equation and the single well control reserve 通过分析该区的试采井资料，得到了指数式产能方程、二项式产能方程及油井产能递减方程，同时计算了单井控制可采储量。
In the end , the seismic facies have been transferred into sedimentary facies , and the results show that the shallow lake , semi - deep lake and shore lake sub - facies were mainly developed in the study area 编制了研究区地震相平面分布图，同时利用单井资料对和1 、和5井进行了单井沉积相分析。
Carry on computational analysis and compare the model with actually with ideal model and project , have drawn some basic laws during the hole precipitation of the base of well of horizontal well 用理想模型和工程实际对模型进行计算分析和对比，得出了水平单井在基坑降水中的一些基本规律。
The program has been compiled by visual basic programming language , based on which the analysis of single well sedimentary microfacies and the study of the plane sedimentary facies are acomplished finally 同时还研制了利用神经网络进行沉积微相自动识别程序。利用此程序对研究区进行单井沉积微相的分析及平面相研究。
The proper injection allocation rate of well can effectively relieve the contradictions of plane , interlayer and inherent layers , and improve the effects of oilfield exploitation by waterflood or water drive process 合理的单井配置注量，可以有效缓解平面矛盾、层间矛盾、层内矛盾和提高水驱油田开发效果、水驱采收率。
Single well accounting is becoming more and more important with the increasingly prominent contradiction between more difficult exploitation and less and less investment year by year in the mid - late period of oilfield development 摘要随着油田开发进入中后期，开采难度的加大与资金投入逐年减少的矛盾日益突出，则单井核算就显得尤为重要。
( 7 ) axisymetrical analytical solutions of vacuum preloading was deduced to compute pore water pressure and degree of consolidation , the effect of vacuum loading speed , well resistance and smear were considered ( 7 )在轴对称单井模型的基础上，推导了考虑真空荷载施加过程的真空预压下地基孔压及固结度的解析解，同时可考虑井阻、涂抹等因素。
