【摘要】：隨著石油勘探開發(fā)程度的逐漸加深,致密砂巖氣藏的經(jīng)濟(jì)價(jià)值逐漸被人們所認(rèn)識(shí),其勘探開發(fā)已經(jīng)成為國(guó)內(nèi)外石油工業(yè)的研究熱點(diǎn)和前沿問(wèn)題。但復(fù)雜的成因以及裂縫的發(fā)育等,使得致密砂巖儲(chǔ)層具有巖性致密、低孔隙度、低滲透率、儲(chǔ)層非均質(zhì)性強(qiáng)和氣水關(guān)系復(fù)雜等特點(diǎn),這給致密砂巖儲(chǔ)層測(cè)井解釋評(píng)價(jià)研究增加了難度。 洛伊地區(qū)三疊系致密砂巖儲(chǔ)層是本次研究的目的層段。由于該區(qū)屬于致密砂巖儲(chǔ)層,加之勘探程度較低,測(cè)井評(píng)價(jià)過(guò)程中存在如下主要問(wèn)題：①儲(chǔ)層裂縫特征研究沒有深入開展,裂縫評(píng)價(jià)僅限于定性說(shuō)明；②常規(guī)測(cè)井資料識(shí)別流體困難；③區(qū)塊無(wú)鄰井試油資料,沒有建立定量的解釋標(biāo)準(zhǔn),準(zhǔn)確評(píng)價(jià)致密砂巖含氣飽和度困難。因此,開展洛伊地區(qū)三疊系致密砂巖測(cè)井解釋評(píng)價(jià)研究,建立一套合適的測(cè)井評(píng)價(jià)標(biāo)準(zhǔn),為油田下一步勘探開發(fā)提供依據(jù),具有十分重要的作用和意義。 本文在前期文獻(xiàn)調(diào)研的基礎(chǔ)上,結(jié)合收集的常規(guī)測(cè)井資料以及巖心物性、水分析、成像測(cè)井資料,從儲(chǔ)層四性關(guān)系、裂縫識(shí)別及有效性評(píng)價(jià)、儲(chǔ)層參數(shù)模型建立、儲(chǔ)層流體性質(zhì)識(shí)別與測(cè)井資料綜合處理等方面進(jìn)行測(cè)井解釋評(píng)價(jià)方法研究。研究認(rèn)為：①譚莊組和椿樹腰組儲(chǔ)層礦物成分類似,巖性以巖屑砂巖、巖屑長(zhǎng)石砂巖、長(zhǎng)石巖屑砂巖為主,譚莊組孔隙度為0.6%～12%,滲透率在(0.017～1.38)×10-31,tm2,椿樹腰組孔隙度為0.4%～8.2%,滲透率在(0.015～19.1)×10-3μm2,均屬于特低孔、特低滲致密砂巖儲(chǔ)層。②本區(qū)裂縫較發(fā)育,主要發(fā)育角度較大的斜交縫和高角度縫,總體上譚莊組段裂縫比椿樹腰組發(fā)育。并應(yīng)用巖心滲透率增大系數(shù)法和成像測(cè)井法評(píng)價(jià)裂縫有效性。另分析了巖石顆粒粗細(xì)、巖石中鈣質(zhì)、白云質(zhì)成分含量、泥質(zhì)含量等對(duì)裂縫發(fā)育的影響。③采用“巖心刻度測(cè)井”方法,建立研究區(qū)常規(guī)儲(chǔ)層參數(shù)計(jì)算模型；運(yùn)用阿爾奇公式(巖電實(shí)驗(yàn)分析確定a、b、m、n值)計(jì)算含水飽和度。④運(yùn)用了4種流體性質(zhì)判別方法,其中模糊概率法、縱橫波速度比值法效果較好,電阻率與聲波、密度交會(huì)法次之。⑤運(yùn)用經(jīng)驗(yàn)統(tǒng)計(jì)法和試氣點(diǎn)約束法確定了儲(chǔ)層孔滲下限,結(jié)合試油、錄井及測(cè)井資料,根據(jù)繪制的試油層位電阻率與孔隙度交會(huì)圖確定譚莊組和椿樹腰組含氣飽和度下限值。 本論文的完成為洛伊地區(qū)三疊系致密砂巖儲(chǔ)層特征分析、儲(chǔ)層參數(shù)模型的建立、流體識(shí)別和儲(chǔ)層下限及解釋標(biāo)準(zhǔn)的建立方面提供了一套切實(shí)可行的方法,為全面開展洛伊地區(qū)三疊系致密砂巖儲(chǔ)層的勘探開發(fā)提供了夯實(shí)的測(cè)井解釋依據(jù)。
[Abstract]:With the deepening of petroleum exploration and development, the economic value of tight sandstone gas reservoir is gradually recognized. Its exploration and development has become the research hotspot and frontier problem of petroleum industry at home and abroad, but the complex genesis and the development of fractures make the tight sandstone reservoir have tight lithology, low porosity and low permeability. The strong heterogeneity of reservoir and the complex relationship between gas and water increase the difficulty of logging interpretation and evaluation of tight sandstone reservoir. Triassic tight sandstone reservoir is the target formation of this study, because this area belongs to tight sandstone reservoir, and the exploration degree is low. In the process of logging evaluation, the following main problems exist: the research on fracture characteristics of reservoir W1 has not been carried out thoroughly, and the fracture evaluation is limited to qualitative explanation; (2) it is difficult to identify fluid by conventional logging data; In block 3, there are no adjacent well test data, no quantitative interpretation standard has been established, and it is difficult to accurately evaluate the gas saturation of tight sandstone. Therefore, the study on interpretation and evaluation of Triassic tight sandstone logging in Loy area is carried out. It is of great importance and significance to establish a set of appropriate logging evaluation criteria to provide the basis for the exploration and development of oil fields in the next step. Based on the previous literature research, this paper combines the conventional logging data and core physical properties, water analysis, imaging logging data, from the relationship between the four properties of reservoir, fracture identification and effectiveness evaluation. The reservoir parameter model, reservoir fluid property identification and logging data comprehensive processing are studied in logging interpretation and evaluation methods. It is considered that the reservoir mineral composition of the W1 Tanzhuang formation and the Chunshuyao formation is similar to that of the Chunshuyao formation. Lithology is dominated by lithic sandstone, lithic feldspar sandstone, feldspathic sandstone, porosity of Tan Zhuang formation is 0.612 and permeability is 0.017 ~ 1.38) 脳 10 ~ (-31) m ~ 2. The porosity of the Chunshu waist formation is 0.4 ~ 8.2, and the permeability is 0.015 ~ 19.1 脳 10 ~ (-3) 渭 m ~ (2), all of them belong to ultra-low porosity, and the fracture of this area is relatively developed in the area of ultra-low permeability tight sandstone reservoir .2. The main development angle of oblique seam and high angle seam. On the whole, the fractures in the Tan Zhuang formation are more developed than those in the Chunshuyao formation. The core permeability increase coefficient method and imaging logging method are used to evaluate the validity of the fractures. In addition, the size of the rock particles, the content of calcium in the rock and the dolomite composition are analyzed. The influence of mud content on fracture development. 3. By using "core calibration logging" method, the conventional reservoir parameter calculation model in the study area is established. By using Archie formula (rock electricity experimental analysis to determine the value of a bbmnn), four methods are used to judge the water saturation. Among them, the fuzzy probability method and the velocity ratio method of longitudinal and shear waves are more effective. The resistivity and acoustic wave and density intersection method are used to determine the lower limit of reservoir porosity and permeability by means of empirical statistics method and gas test point constraint method combined with oil testing logging and logging data. Based on the plotted plot of resistivity and porosity, the lower limit of gas saturation of Tanzhuang formation and Chunshuyao formation is determined. The completion of this paper provides a set of feasible methods for the analysis of the characteristics of Triassic tight sandstone reservoir, the establishment of reservoir parameter model, fluid identification and the establishment of reservoir lower limit and interpretation standard. It provides a solid log interpretation basis for the exploration and development of the Triassic tight sandstone reservoir in the Loy area.
