【摘要】：完井,即油氣井的完成,是聯(lián)系鉆井工程和采油工程兩個(gè)生產(chǎn)環(huán)節(jié)的一個(gè)重要生產(chǎn)環(huán)節(jié),其周期從鉆井作業(yè)開(kāi)始,直至投產(chǎn)作業(yè)結(jié)束,是油田產(chǎn)能建設(shè)的重要組成部分。完井業(yè)務(wù)的效率與質(zhì)量直接影響到油田的產(chǎn)量大小及今后采油工作能否順利進(jìn)行,從而直接關(guān)系到油田開(kāi)發(fā)的經(jīng)濟(jì)效益。基于智能移動(dòng)設(shè)備的完井運(yùn)行信息移動(dòng)服務(wù)平臺(tái)的建立,可幫助工作人員不管置身何地,都可以隨時(shí)隨地辦公,提高了油田信息管理的效率。針對(duì)完井業(yè)務(wù)移動(dòng)環(huán)境下具有頻繁斷接性、資源有限性、網(wǎng)絡(luò)通信不對(duì)稱性等特點(diǎn),對(duì)完井業(yè)務(wù)的移動(dòng)事務(wù)處理進(jìn)行研究,對(duì)提高移動(dòng)完井業(yè)務(wù)處理事務(wù)的性能,提高在完井信息管理的效率有著重要的意義。由于完井業(yè)務(wù)多在野外工作,而野外的移動(dòng)計(jì)算環(huán)境下具有頻繁斷接性、資源有限性、網(wǎng)絡(luò)通信不對(duì)稱性等特點(diǎn),導(dǎo)致事務(wù)處理是效率低。針對(duì)此問(wèn)題,本文主要研究?jī)?nèi)容是面向完井業(yè)務(wù)的移動(dòng)事務(wù)處理,主要的研究?jī)?nèi)容如下:基于完井的讀寫時(shí)間戳樂(lè)觀并發(fā)控制協(xié)議。由于在移動(dòng)計(jì)算環(huán)境的限制下,在事務(wù)進(jìn)行操作時(shí),完井運(yùn)行信息移動(dòng)服務(wù)平臺(tái)在進(jìn)行并發(fā)控制時(shí)會(huì)比傳統(tǒng)環(huán)境下的效率低下,然而移動(dòng)計(jì)算環(huán)境是無(wú)法改變的,因此針對(duì)這個(gè)問(wèn)題,為了提高完井運(yùn)行信息移動(dòng)服務(wù)平臺(tái)并發(fā)控制的時(shí)候效率,根據(jù)完井運(yùn)行信息移動(dòng)服務(wù)平臺(tái)大部分的數(shù)據(jù)讀多寫少?zèng)_突較少特點(diǎn),采取了樂(lè)觀并發(fā)控制協(xié)議,引入時(shí)間戳,對(duì)基本的樂(lè)觀并發(fā)控制協(xié)議進(jìn)行改進(jìn)�；谕昃臋�(quán)值自適應(yīng)移動(dòng)事務(wù)處理模型。由于在完井業(yè)務(wù)中存在一小部分熱點(diǎn)數(shù)據(jù),在處理這部分事務(wù)時(shí)如果應(yīng)用改進(jìn)后的樂(lè)觀并發(fā)控制協(xié)議易出現(xiàn)并發(fā)過(guò)多時(shí)因回滾事務(wù)多而導(dǎo)致效率低下的問(wèn)題。針對(duì)該問(wèn)題,結(jié)合改進(jìn)后的樂(lè)觀并發(fā)控制協(xié)議,提出了基于權(quán)值自適應(yīng)的移動(dòng)事務(wù)處理模型,根據(jù)完井移動(dòng)計(jì)算環(huán)境和完井業(yè)務(wù)所訪問(wèn)的數(shù)據(jù)情況,通過(guò)權(quán)值來(lái)自動(dòng)選擇移動(dòng)事務(wù)處理的相應(yīng)策略。將本文的研究的移動(dòng)事務(wù)處理應(yīng)用在第三采油廠的完井運(yùn)行信息移動(dòng)服務(wù)平臺(tái),利用油田現(xiàn)場(chǎng)的移動(dòng)計(jì)算環(huán)境進(jìn)行測(cè)試,驗(yàn)證了算法的實(shí)用性,提高了系統(tǒng)的性能,節(jié)省網(wǎng)絡(luò)帶寬,對(duì)于提高油田信息管理的效率,促進(jìn)油田產(chǎn)能都有著重要的意義。
[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.
