【摘要】：隨著油田開發(fā)的逐年深入,低品質(zhì)資源逐漸開發(fā),分析評價方法已不完全適用。英臺氣田是一個低品質(zhì)資源,由四個區(qū)塊組成,雖然都為火山巖儲層,但分為火山巖熔巖儲層和火山碎屑巖儲層,并且各區(qū)塊探井試氣產(chǎn)能差異較大(0.2-18萬方),試氣過程中產(chǎn)少量凝析油,為此對于處于前期評價階段的復(fù)雜非均質(zhì)氣藏,由于單純的靜態(tài)地質(zhì)研究方法在有效儲層識別、單井控制連通范圍及形態(tài)描述方面精度不夠,目前國內(nèi)外廣泛利用試井、試采動態(tài)資料在儲層動態(tài)特征描述方面的優(yōu)勢,通過大量高精度試井壓力資料的錄取及精細(xì)分析研究,深入刻畫描述了單井控制有效儲層的參數(shù)及展布形態(tài)、單井控制動態(tài)儲量大小等開發(fā)關(guān)鍵參數(shù),以此對氣井開發(fā)生產(chǎn)動態(tài)進(jìn)行預(yù)測,并作為指導(dǎo)氣田開發(fā)規(guī)劃與開發(fā)主體技術(shù)選擇的依據(jù)。對英臺氣藏通過相圖判別法及經(jīng)驗統(tǒng)計法進(jìn)行相態(tài)特征確定、多參數(shù)分析產(chǎn)能影響因素分析、氣井試井及產(chǎn)能評價方法研究、氣井動態(tài)分析綜合評價及產(chǎn)能預(yù)測等方法對該地區(qū)形成了一套可行的分析評價方法。針對氣田火山巖氣藏的復(fù)雜性,以及吉林油田同類含凝析油氣藏的獨特性,通過分析評價深化認(rèn)識火山巖儲層的連通性、單井控制范圍、氣井產(chǎn)能提高的潛力、底水錐進(jìn)的影響、水平井效果評價等,實現(xiàn)深層天然氣的安全、高效開發(fā)意義重大。
[Abstract]:With the deepening of oilfield development and the gradual development of low-quality resources, the analysis and evaluation method is not fully applicable. Yingtai gas field is a low-quality resource, consisting of four blocks, although all of them are volcanic reservoirs. However, it can be divided into volcanic lava reservoir and pyroclastic reservoir, and the gas test productivity of exploration wells in each block is quite different from 0.2-18 million square meters, and a small amount of condensate oil is produced in the process of gas testing. Therefore, for the complex heterogeneous gas reservoirs which are in the early stage of evaluation, Because the static geological research method is not accurate enough in effective reservoir identification, single well control connectivity and shape description, the advantages of well test and production test dynamic data in reservoir dynamic feature description are widely used at home and abroad. By taking and analyzing a large number of high precision well test pressure data, the parameters and distribution of effective reservoir controlled by single well and the key parameters of development such as the size of dynamic reserves controlled by single well are described in depth. Based on the prediction of gas well development and production performance, and as the basis for guiding gas field development planning and development main technology selection, the phase behavior characteristics of Yingtai gas reservoir are determined by phase diagram discrimination and empirical statistics. Multi-parameter analysis of productivity factors analysis, well testing and productivity evaluation method research, The comprehensive evaluation of gas well performance analysis and productivity prediction have formed a set of feasible analysis and evaluation methods for this area. In view of the complexity of volcanic gas reservoirs in gas fields and the uniqueness of similar condensate reservoirs in Jilin Oilfield, By analyzing and evaluating the connectivity of volcanic reservoir, the control range of single well, the potentiality of gas well productivity improvement, the influence of bottom water coning, and the evaluation of horizontal well effect, it is of great significance to realize the safety and high efficiency development of deep gas.
