螺杆钻具是井底动力钻具, 主要用于油( 水) 井 钻塞、 磨铣、 侧钻以及加深井底等多种作业的一种新 型工具。尤其是推广使用可钻式桥塞以后, 更增加 了修井作业中钻、 铣的工作量和难度, 因此对这 磨、 种新型钻具扭矩的要求不断加大。为此, 根据生产 工艺不断发展、 完善的需要, 研制和生产单位对螺杆 钻具的功能进行了必要的改进, 主要表现在由小扭 矩、 高转速逐渐向大 扭矩、 低转 速发展112 。由此 可 见, 扭矩和转速是螺杆钻具的两项非常重要的技术 指标。但是在生产过程中, 由于频繁使用, 会造成螺 杆钻具密封件泄漏; 长时间的运转, 使马达的效率及 输出功率发生改变, 这些因素都会造成螺杆钻具输 出扭矩和转速达不到规定指标或设计指标, 从而直 接影响生产, 造成不必要的经济损失。因此, 有必要 研制一种螺杆钻具参数测试系统, 在钻具下井前对 其各项参数进行测试以确保生产的顺利进行。

( 5) : 15~ 18 During the process of well logging, the measuring of flow parameter would be paused. At this time, the logging job has to be stopped and then the tool need to be repaired, thus the logging t ime and cost are increased. In order to avoid this case, we must detail analysize and improve the structure of centralizing spring. In this paper, two methods about the original and improved structure of centralizing spring are compared and calculated. The result showes the improved struc ture has following advantage, no weak force point , high qualification, low production cost, high tensile strength and high reliabilty and so on. The improved structure of centralizing spring is more efficient than that of before in production log ging.

The Reason Analysis and Resolution of Winch -roller Chain -pin Breaking on the 3700 Computerized Logging System. PI, 1998, 12( 5) : 23~ 24 The imported winch roller chain pins on the 3700 computerized logging system have broken many t imes and greatly affected to our work. In order to find out the breaking reasons and the methods of solving this problem. We test and analysize both materials of the imported and the domestic produced roller chain pins, and find the breaking reason is the improper process on heating treatment, which results in the high hardness in the center of the pin, and the britlleness of the material increasing. By select ing the domestic produced roller chain instead of the imported, and tested in more than 40 wells at logging sites, there was no more bresking of the pins. It has been proved that the imported roller chain can be completely replaced by the domestic produced roller chain, which is higher in quality and lower in price, and easily available.

Autopore ?9220 Capillary Pressure Curve Determinative In strument. PI, 1998, 12( 5) : 33~ 35 During the exploration and development of oilfied, we must study the pore structure of reservior core got from oil well in order to evaluate reservior. One of the resesach methods is the determination of core caplillary pressure curre.

PI, 1998, 12( 5) : 36~ 37, 40 Computer network technology is widely used in oil exploration equipment. The one of network is resource sharing. In order to use the sharing resources more effectively, it is necessary to solve network confliction. Distributed memory shar ing is a good method to solve these problems. A distributed system appears to the acquisition of users computer as a single computer. To deal with hardware, the machine is autonomous, and to deal with software, the machine is a single com puter, it plays an important role in distributed system. The design method of system softwqre is largely determined by the operation system. Multiple CPU computer systems fall into two categories: those that have shared memory and those that do not . The shared memory machines ( multiprocessors) are easier to program but harder to build, whereas the machines without shared memory ( mult icomputers) are harder to program but easier to build. Distributed shared memory technique can make the multicomputers easier to program by the method of simulating shared memory.

The data reduction module can be realized in field instrument by software method, or hardware equipment which synthe sizes a or many compression data techniques. The actual appication showes the seismic data reduction method is as impor tant as that of compression.
