Research OnAutomatic Recognition Of Sandstone Correlation Layer Of Completion

Well completion, the completion of oil and gas well, is a wide range, covering verycomplex technology. The set up of mobile information service platform of the Completionhelp the staffs work at anytime, no matter in the field or anywhere. According to thecharacteristics of the restricted access in mobile environment, the research of mobile accessstrategy of well completion information is significant to increase the speed of completionmobile access, and to improve the real-time office efficiency of oil fields on the mobileinformation service platform of the Well Completion.The research emphasis of this paper is mobile access strategy of the well completioninformation, the main research content is as follows:For mobile access characteristics of well completion information, a kind of prefetchingalgorithm of sequential patterns mining, based on the dependency strength of completionbusiness is put forward through to analysis the business process models of completion andcompletion server access logs, determine the calculation model of the completion dependencystrength and as the weight of sequence, involved in the algorithm of mining, to improved theprefetch algorithm of sequential patterns mining. Experiment shows that the improvedalgorithm can reduce the size of the frequent sequences effectively, mine meaningfulprefetching sequence more efficient, and improve the access speed effectively.To avoid mobile client prefetch on network utilization in the background will influencethe UI thread blocking, this paper proposes an improved Gzip algorithm based on the serviceinformation compression model of completion, through establish templates of SOAP messageand completion data to generate a message automate template processor matching withcompletion information service, transmits the completion service information of improvedcoding to Gzip algorithm for the secondary compression. The improved algorithm can reducethe storage space of data objects relatively, prefetching message load and response time.Combined with the prefetching and compression integrated access strategy, applied inWell completion operation mobile integrated management software, using the oil field scenecompletion mobile access data for testing, proved the efficiency and practicability of thealgorithm. It has important significance in the increase in oil field real-time mobile office.
