【摘要】：針對長嶺氣田登婁庫組氣藏地質(zhì)條件復(fù)雜、開發(fā)難度大等特點(diǎn),首先通過地質(zhì)特征再認(rèn)識(shí)及富集區(qū)優(yōu)選研究,應(yīng)用地質(zhì)、地震、氣藏工程等多學(xué)科的綜合研究,最終形成一套適合長嶺氣田登婁庫組氣藏水平井整體開發(fā)及效果評(píng)價(jià)技術(shù),實(shí)現(xiàn)登婁庫組各主力層系水平井高效開發(fā)方式。本文通過對登婁庫組氣藏地質(zhì)特征再認(rèn)識(shí)研究,為優(yōu)化井位部署提供了依據(jù)。應(yīng)用不斷豐富的鉆、錄、測資料,精細(xì)刻畫儲(chǔ)層展布規(guī)律,明確Ⅲ、Ⅳ砂組整體含氣,優(yōu)質(zhì)儲(chǔ)層主要集中在構(gòu)造主體區(qū)域,為水平井主要目的層。通過應(yīng)用疊前AVO含氣性烴檢測及多條件約束氣藏地質(zhì)建模技術(shù),分析外圍含氣性及一、二砂組富集區(qū)分布規(guī)律。開展以經(jīng)濟(jì)效益為終極目標(biāo),評(píng)價(jià)登婁庫組氣藏水平井開發(fā)的適應(yīng)性,確立水平井多段壓裂開發(fā)方式,形成了水平井優(yōu)化部署設(shè)計(jì)技術(shù)。通過水平井現(xiàn)場實(shí)施,細(xì)化導(dǎo)向流程,形成水平井現(xiàn)場實(shí)施技術(shù)。針對深層致密氣藏建立水平井評(píng)價(jià)指標(biāo)體系,形成水平井開發(fā)效果評(píng)價(jià)技術(shù)。最終明確了長嶺氣田登婁庫組氣藏整體開發(fā)方案,即采用直井+水平井開發(fā),共設(shè)計(jì)氣井60口井,其中利用已鉆老井15口,含4口直井,新鉆生產(chǎn)井45口(均為水平井),形成天然氣8.0億方年產(chǎn)能力,采氣速度2.7%,穩(wěn)產(chǎn)年限為8年,實(shí)現(xiàn)長嶺登婁庫組氣藏整體高效開發(fā)。
[Abstract]:In view of the complex geological conditions and difficult development of the gas reservoirs in the Denglouku formation of Changling gas field, firstly, through the recognition of the geological characteristics and the optimal selection of rich areas, the comprehensive research on applied geology, earthquake, gas reservoir engineering and so on is made. Finally, a set of techniques suitable for the overall development and evaluation of horizontal wells of gas reservoirs in Denglooku formation of Changling gas field were formed to realize the efficient development of horizontal wells in each main formation of Denglooku formation. In this paper, the geological characteristics of gas reservoirs in Denglooku formation are studied again, which provides the basis for optimizing well location deployment. The application of abundant drilling, recording, logging data, fine description of the distribution of the reservoir, the determination of the 鈪，
