In line with the problems of water production and liquid accumulation in gas wells, the technology for foam drainage gas recovery is mainly used in Sulige Gas Field. The traditional technology for foam drainage gas recovery is manually injected from trucks, which has a lot of work and costs much, and gas wells are hard to control. For this reason, and in combination with ifeld demand and wellhead conditions, a device has been developed which can remote control and automatically drop solid ball-like displacing agent, which increases the foaming time of the agent, improves the agent efifciency and also effectively reduces the labor intensity and labor cost. This device is powered by solar panels, so it has a low energy consumption and can satisfy the demand for chemical addition accord-ing to ifxed time interval, ifxed amount and ifxed frequency. The ball storage barrel is designed to be at atmospheric pressure and easy to add bubbles to displace balls manually. The success test of this technique provides a new concept for digitized drainage gas recovery for Sulige Gas Field and has a broad application prospect. It is suggested to further promote the use this technique.

Taking BOOST circuit which frequently causes EMC problems as an example,a double-circle model of the electromagnetic radiation was established to analyze BOOST circuit's electromagnetic radiation field and to present an analytic solution; Ansoft software was used to simulate and calculate the model and then the circuit's near field radiation with shield was compared with that without a shield.This research can provide both theoretical and practical foundation for shield design of the switched-mode power supply.

Gas well can be divided into three kinds of different type in Sulige gas field:continuous stable production wells, natural jet production wells and intermittent production wells. According to the three types,gas wells respectively effusion are selected to foam test. Thus it has some recognize of gas well which are different gas production foam drainage gas recovery effect,and some guidance on the Sulige gas field drainage gas.

In the oil field development of contain H_2S,the H_2S corrosion problem very serious,not only decay casing,and the corrosion of cement sheath also very serious。In these oil field development,well cementation becomes complicated,if we can study clear the H_2S corrosion problem of the well cement sheath,so the prevented measures is better to adopt and prevent the H_2S corrosion from well cement sheath,and even prevent the corrosion from casing。The paper analyzed the corrosion mechanisms and impact factors of H_2S corrosion of well cement sheath,elaborated the anti-corrosion mechanism,method,cement slurry system of H_2S corrosion of cement,the types of anti-corrosion cement slurry of H_2S corrosion。

In gas well,downhole choke is a process of depressurization and cooling.This technology is widely applied to Sulige gasfield and plays an important role in field development and production.By analyzing the principle of the technology,a method to determine choke parameters is presented in this paper.Combined with in-situ application to Sulige gasfield,the effect and the failure cause and fishing of gas choke are analyzed.Several suggestions and comments on improvement are also proposed.

In the development process gas reservoir will produce water or condensate liquid that will accumulate in the bottom if not be discharged in time.That will reduce gas production,crease bottom pressure,ultimately gas well shut down.With the development of the gas field produced water issues need attention more and more.To solve these problems in su-48 block the paper selected a new anti-oil ERD-05g foaming agent and carried a series of tests in 2 wells.Tests had achieved good results and reached the purpose of drainage gas wells in Sulige gas field.

The problems existed in the initial running of 20kt/a sulfur recovery tail gas treatment unit of Lanzhou Petrochemical Company were analyzed,including blinding of quench tower,serious corrosion of equipments,temperature run away of hydrogenation reactor bed and possible oxidation of catalyst during its unloading etc.The problems were resolved by increasing the inlet temperature of hydrogenation reactor,adjusting thruput,controlling the gas to air ratio of Claus reaction,and canceling out desactivation and reactivation of catalyst after its unloading and protecting it in nitrogen.Through adorpting those measures,the sulfur dioxide content in discharged flue gas decreased to 330mg/m3,and the long period running could be realized.

In Changqing gas field after many years development low-pressure gas wells increased gradually so result in a lot of production problems.In this paper a new injecting tehnology was introduced that can increase the pressure of low-pressure gas well by highpressure gas well without other power.The injector was devolped and tested in field,and the effect can prove that the technology was feasible,economic and valuable.In addition,the pater introduced a multi-speed injecting technology that can inject gas step by step.When single injector can't complete injecting effect the multi-speed injecting technology can solve the problem to ensure the production of gas well.

提高管线钢钢级是当今建设大口径、高压力管道首先考虑的措施。国外X70级管线钢已成为20世纪90年代末输气管材用钢的主流。迄今全世界已建成的X80钢级输气管道总长已超过500km,并且在生产技术与管理方面均日趋成熟。管道建设中钢管每米质量的降低意味着更大的经济性和施工可行性。因此在国内长距离、大管径、高压输气管道建设中应用X80管线钢是可行的。
