In the process of realizing the remote control of electromotor meter, it probes into the realization of the GPRS wireless collector emphatically which is on the kernel ground. It adopts the means of area-centralizing control to manage the electromotor meters affiliated by it. It communicates with the central control station by GPRS Modem and transmits the commands and data to the instrument by wireless, which makes the collection and transmission of the field data come true. In the process of realizing the remote control of voltage transformer meter, according to the actual requirement, it adopted the chips and modules that are different from the front means to design and realize the GPRS wireless communicating controller corresponding with the devices. It also introduces the mixed—mode Communication integrating the GSM with GPRS to settle the problem that too many GPRS terminals connecting with the central control station synchronously will affect the performance of the central control station.As a whole system, the central control station is the kernel of the digital oil field.

The fluid film bearing-flexible rotor nonlinear system with squeeze film damper is modeled practically using the finite element method and the Hamilton principle.(3) The film forces produced by fluid film bearing and squeeze film damper are determined by finite element method at any moment, and the Jacobian matrix is also determined.(4) A method for analyzing the dynamics of a large system with local nonlinearities is presented. The stability and bifurcation of the equilibrium position and the unbalance responce of a fluid film bearing-flexible rotor system with squeeze film damper are investigated based on the assumption of an incompressible lubricant together with the long bearing approximation for fluid film bearing, short bearing approximation for squeeze film damper and the"π"film cavitation model.

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。
