【摘要】：完井,即油气井的完成,是联系钻井工程和采油工程两个生产环节的一个重要生产环节,其周期从钻井作业开始,直至投产作业结束,是油田产能建设的重要组成部分。完井业务的效率与质量直接影响到油田的产量大小及今后采油工作能否顺利进行,从而直接关系到油田开发的经济效益。基于智能移动设备的完井运行信息移动服务平台的建立,可帮助工作人员不管置身何地,都可以随时随地办公,提高了油田信息管理的效率。针对完井业务移动环境下具有频繁断接性、资源有限性、网络通信不对称性等特点,对完井业务的移动事务处理进行研究,对提高移动完井业务处理事务的性能,提高在完井信息管理的效率有着重要的意义。由于完井业务多在野外工作,而野外的移动计算环境下具有频繁断接性、资源有限性、网络通信不对称性等特点,导致事务处理是效率低。针对此问题,本文主要研究内容是面向完井业务的移动事务处理,主要的研究内容如下:基于完井的读写时间戳乐观并发控制协议。由于在移动计算环境的限制下,在事务进行操作时,完井运行信息移动服务平台在进行并发控制时会比传统环境下的效率低下,然而移动计算环境是无法改变的,因此针对这个问题,为了提高完井运行信息移动服务平台并发控制的时候效率,根据完井运行信息移动服务平台大部分的数据读多写少冲突较少特点,采取了乐观并发控制协议,引入时间戳,对基本的乐观并发控制协议进行改进。基于完井的权值自适应移动事务处理模型。由于在完井业务中存在一小部分热点数据,在处理这部分事务时如果应用改进后的乐观并发控制协议易出现并发过多时因回滚事务多而导致效率低下的问题。针对该问题,结合改进后的乐观并发控制协议,提出了基于权值自适应的移动事务处理模型,根据完井移动计算环境和完井业务所访问的数据情况,通过权值来自动选择移动事务处理的相应策略。将本文的研究的移动事务处理应用在第三采油厂的完井运行信息移动服务平台,利用油田现场的移动计算环境进行测试,验证了算法的实用性,提高了系统的性能,节省网络带宽,对于提高油田信息管理的效率,促进油田产能都有着重要的意义。
[Abstract]:Completion, that is, the completion of oil and gas wells, is an important production link connected with drilling engineering and oil production engineering. The cycle of completion is from the beginning of drilling operations to the completion of production operations, which is an important part of oilfield productivity construction. The efficiency and quality of the completion business directly affect the production of the oilfield and whether the oil production can be carried out smoothly in the future, which is directly related to the economic benefits of oilfield development. The establishment of completion information mobile service platform based on intelligent mobile devices can help the staff to work wherever they are and improve the efficiency of oil field information management. In view of the characteristics of frequent breaking, limited resources and asymmetry of network communication in mobile well completion environment, the mobile transaction processing of completion service is studied, and the performance of mobile completion transaction is improved. It is of great significance to improve the efficiency of well completion information management. Due to the fact that the completion service mostly works in the field, the mobile computing environment in the field has the characteristics of frequent disconnection, limited resources and asymmetric network communication, which leads to the low efficiency of transaction processing. In order to solve this problem, the main content of this paper is mobile transaction processing for completion service. The main research contents are as follows: the optimistic concurrency control protocol based on completion time stamp for reading and writing. Due to the limitation of mobile computing environment, when the transaction is operated, the completion information mobile service platform is less efficient than the traditional environment in concurrency control, but the mobile computing environment can not be changed. To solve this problem, in order to improve the efficiency of concurrent control of completion operation information mobile service platform, according to the characteristics of completion operation information mobile service platform, most of the data read more, write less conflict, The optimistic concurrency control protocol is adopted and the time stamp is introduced to improve the basic optimistic concurrency control protocol. A weighted adaptive mobile transaction model based on completion is presented. Due to the existence of a small number of hot data in the completion business, if the improved optimistic concurrency control protocol is applied to deal with this part of the transaction, it is easy to cause inefficiency due to the excessive concurrency due to the large number of rollback transactions in the application of the improved optimistic concurrency control protocol. Aiming at this problem, combined with the improved optimistic concurrency control protocol, a mobile transaction processing model based on weight adaptive is proposed, which is based on the completion mobile computing environment and the data accessed by the completion service. The corresponding strategy of mobile transaction processing is automatically selected by weight value. The mobile transaction processing studied in this paper is applied to the mobile service platform of the completion operation information in the third oil production plant. The mobile computing environment in the oil field is used to test the algorithm, which verifies the practicability of the algorithm and improves the performance of the system. Saving network bandwidth is of great significance for improving the efficiency of oilfield information management and promoting oilfield productivity.
