【摘要】：伴隨著我國經(jīng)濟持續(xù)發(fā)展,能源戰(zhàn)略安全形勢日益嚴峻,能源需求越來越大,供需矛盾日益增加。天然氣的開發(fā)利用愈加受到重視,因此對針對天然氣田勘探與開發(fā)的力度也不斷加大,由于近幾年深層氣井的壓裂、固井等鉆采技術都取得了較大突破,使得近年來大慶油田產(chǎn)氣量也逐年增加,僅2006年就已達24.4億立方米。而大慶油田“穩(wěn)四上五”目標的提出,更是使得天然氣勘探開發(fā)已經(jīng)呈現(xiàn)出跨度式增長態(tài)勢。但是隨著氣田的開發(fā)規(guī)模越來越大,氣田的地質(zhì)條件和動態(tài)生產(chǎn)情況也日趨復雜,相關的動態(tài)監(jiān)測及其分析工作也就愈發(fā)重要。如何更加有效的開展氣田動態(tài)監(jiān)測及解釋評價研究工作是目前的首要任務。例如在氣藏生產(chǎn)管理中,重點開展氣田動態(tài)監(jiān)測工作,通過對有關資料進行收集、分析,滿足資料錄取和動態(tài)分析需要,為氣田合理開發(fā)提供有利的分析依據(jù),從而達到正確認識、開發(fā)氣藏的目的,在壓力恢復試井、建立和求解不穩(wěn)定滲流數(shù)學模型、氣井合理關井時間的確定方法等方面的了解。試井是氣田開發(fā)動態(tài)監(jiān)測中的重要技術手段之一,試井工程師目前最亟待解決的問題就是,在面對越來越復雜的地質(zhì)條件下,通過分析利用試井資料發(fā)現(xiàn)并解決氣田開發(fā)中遇到的問題。反之亦然,如何利用試井資料診斷氣田開發(fā)中的矛盾也成為了檢驗試井資料的有效手段。所以,嚴峻的開發(fā)形勢給試井技術帶來了挑戰(zhàn)的同時也帶來了發(fā)展機遇,試井技術在不斷解決開發(fā)矛盾的同時也在逐步的發(fā)展和完善。本文總結了試井技術的發(fā)展過程,并以大慶油田徐深氣田為例,闡述了試井解釋資料在氣田動態(tài)開發(fā)過程中的實際應用,具體分析了不同試井資料在氣田開發(fā)過程中相應的指導作用。同時在氣井二項式產(chǎn)能方程基礎上,建立了能夠直接描述流壓與產(chǎn)量關系的、且能計算地層壓力的廣義產(chǎn)能方程模型。并通過與常規(guī)的作圖法和最小二乘法對比驗證此方法是可靠的。
[Abstract]:With the sustainable development of our economy, the security situation of energy strategy is becoming more and more severe, the energy demand is increasing, and the contradiction between supply and demand is increasing day by day. The exploitation and utilization of natural gas have been paid more attention to, so the exploration and development of natural gas fields have been increasingly strengthened. Due to the fracturing of deep gas wells in recent years, drilling and production techniques such as cementing have made great breakthroughs. In recent years, Daqing Oilfield gas production has increased year by year, in 2006 alone has reached 2.44 billion cubic meters. However, the target of "stable four and top five" in Daqing Oilfield has made the exploration and development of natural gas become more and more spanned. However, with the development of gas field becoming larger and larger, the geological conditions and dynamic production of gas field are becoming more and more complicated, and the related dynamic monitoring and analysis work is becoming more and more important. How to more effectively carry out the research work of gas field dynamic monitoring and interpretation evaluation is the primary task at present. For example, in the production management of gas reservoirs, it is important to carry out the monitoring work of gas field performance. By collecting and analyzing the relevant data, we can meet the needs of data acquisition and dynamic analysis, and provide a favorable analysis basis for the rational development of the gas field. In order to realize the correct understanding and develop the gas reservoir, it is necessary to establish and solve the mathematical model of unstable percolation, to establish and solve the mathematical model of unstable percolation, and to determine the reasonable shut-in time of gas well. Well testing is one of the important technical means in monitoring the development performance of gas field. The most urgent problem to be solved by well test engineers is that, in the face of more and more complicated geological conditions, The problems encountered in gas field development are found and solved through analysis and utilization of well test data. Vice versa, how to use well test data to diagnose the contradiction in gas field development has become an effective means to test well test data. Therefore, the severe development situation not only brings challenges to well testing technology, but also brings opportunities for development. Well test technology is developing and perfecting step by step while solving the development contradiction constantly. This paper summarizes the development process of well test technology, and takes Xushen gas field in Daqing Oilfield as an example to expound the practical application of well test interpretation data in the process of dynamic development of gas field. The guiding role of different well test data in gas field development is analyzed in detail. On the basis of binomial productivity equation of gas well, a generalized productivity equation model which can directly describe the relationship between flow pressure and production rate and can calculate formation pressure is established. Compared with the conventional drawing method and the least square method, the method is proved to be reliable.
