【摘要】：大港油田發(fā)現(xiàn)至今已40余載,黃驊坳陷已進(jìn)入勘探的中晚期階段,勘探難度逐漸增大,油氣聚集區(qū)日趨復(fù)雜使大港探區(qū)勘探工作謀求二次創(chuàng)業(yè)。上世紀(jì)90年代末,大港先后找到了以上古生界煤系地層為油氣源的潛山帶,表明上古生界油氣藏具有較大的勘探潛力。通過(guò)巖心、測(cè)井資料、掃描電鏡、普通薄片、鑄體薄片、壓汞法、X衍射等實(shí)驗(yàn)室分析技術(shù),對(duì)黃驊坳陷進(jìn)行沉積相分析和儲(chǔ)層研究,為后期勘探部署提供科學(xué)依據(jù)。黃驊坳陷石炭-二疊紀(jì)地層從下至上分為本溪組、太原組,山西組、下石盒子組、上石盒子組和石千峰組。黃驊坳陷石炭-二疊紀(jì)地層主要發(fā)育的砂體類型是：河流相砂體主要發(fā)育于上石盒子組、下石盒子組和石千峰組；山西組主要發(fā)育三角洲砂體；潮坪-o_湖相砂體和渴湖-障壁島相砂體主要發(fā)育于本溪組和太原組。黃驊坳陷石炭-二疊紀(jì)有利儲(chǔ)層的砂體類型是河流相砂體和三角洲相砂體。通過(guò)研究黃驊坳陷上古生界砂巖儲(chǔ)集層表明上古生界儲(chǔ)層主要以長(zhǎng)石砂巖和巖屑質(zhì)長(zhǎng)石砂巖為主,但垂向上差異明顯,廣義石英砂巖(包括巖屑質(zhì)石英砂巖和長(zhǎng)石質(zhì)石英砂巖)基本分布于下石盒子組和上石盒子組；儲(chǔ)層內(nèi)石英含量自下而上呈現(xiàn)明顯增加的趨勢(shì),而巖屑含量則表現(xiàn)為自下而上降低的趨勢(shì)。砂巖成分成熟度及結(jié)構(gòu)成熟度都有逐漸降低的趨勢(shì)。整體上,儲(chǔ)層內(nèi)孔滲均相對(duì)較好的層段是河道砂體的下石盒子組,也是進(jìn)一步勘探的重點(diǎn)區(qū)域。其次是太原組,上石盒子組相對(duì)較差。從數(shù)據(jù)上來(lái)看,山西組地層表現(xiàn)出極差的孔滲性能,屬于非滲透層。成巖作用對(duì)研究區(qū)砂巖儲(chǔ)集物性影響表現(xiàn)得非常明顯,在制約儲(chǔ)層儲(chǔ)集物性的諸多因素中,壓實(shí)作用基本決定了砂巖儲(chǔ)集性能的好壞,壓實(shí)作用在儲(chǔ)層物性改造過(guò)程中起了一個(gè)負(fù)面的作用,導(dǎo)致儲(chǔ)層的原生孔隙損失量較大。在砂體埋深的中后期,膠結(jié)作用逐漸取代壓實(shí)作用成為破壞砂體儲(chǔ)集性能的主力軍,粘土巖膠結(jié)物、碳酸鹽膠結(jié)物、硅質(zhì)膠結(jié)物是使砂巖儲(chǔ)集層孔隙度和滲透率降低的主要原因。溶蝕作用(酸性溶蝕和堿性溶蝕)產(chǎn)生了大量的次生孔隙,極大地改善了儲(chǔ)層物性,對(duì)油氣儲(chǔ)集空間的形成起到積極的作用。黃驊坳陷上古生界砂巖儲(chǔ)集空間整體上都是次生形成的,各段均未見(jiàn)原生孔隙留存,以次生粒間溶孔、粒內(nèi)溶孔及鑄模孔為主,僅山西組層段內(nèi)裂縫相對(duì)發(fā)育。次生孔隙的形成極大地改善了儲(chǔ)層物性。整體上,上石盒子組的排驅(qū)壓力較小,喉道分選系數(shù)偏小,表現(xiàn)出來(lái)的孔喉連通性較好；下石盒子和太原組排驅(qū)壓力中等,分選系數(shù)偏小,孔喉連通性略低于上石盒子組；山西組排驅(qū)壓力最大,分選系數(shù)最高,孔喉連通性相對(duì)最差。黃驊坳陷上古生界儲(chǔ)層總體上以特低孔-超低滲、低孔-超低滲物性特征為主。儲(chǔ)層的儲(chǔ)集物性受多方面因素影響,沉積環(huán)境及沉積相決定了砂巖儲(chǔ)集層的原始條件,成巖作用成為了沉積后研究區(qū)儲(chǔ)層物性的主控因素。黃驊坳陷最有利的儲(chǔ)層砂體是下石盒子組和上石盒子組的河流相砂體,儲(chǔ)集物性較好,是本區(qū)上古生界最有前景的儲(chǔ)層。
[Abstract]:Since the discovery of Dagang oil field has been over 40 years, the Huangyan depression has entered the middle and late stage of the exploration, the exploration difficulty is gradually increased, and the oil and gas accumulation area is becoming more and more complex to make the exploration work in the Dagang exploration area to seek for a second start-up. In the late 1990s, Dagang has successively found the above-Paleozoic coal measures strata as the buried hill zone of oil and gas source, which indicates that the upper Paleozoic oil and gas reservoir has great exploration potential. The sedimentary facies analysis and reservoir research were carried out in Huangyan depression by using the laboratory analysis techniques such as core, logging data, scanning electron microscope, ordinary sheet, casting sheet, mercury-pressing method and X-ray diffraction, so as to provide scientific basis for later exploration and deployment. The Carboniferous-Permian strata in the Huangbu depression are divided into Benxi Formation, Taiyuan Formation, Shanxi Formation, Lower Stone Box Group, Shangshi Box Group and Shiqianfeng Group from bottom to top. The main development of the Carboniferous-Permian strata in the Huangbu depression is that the fluvial facies sand body is mainly developed in the upper stone box group, the lower stone box group and the stone thousand peak group, and the Shanxi Formation mainly develops the delta sand body; The sandbodies of the tidal flat-o _ lake facies and the thirsty-barrier island are mainly developed in the Benxi and Taiyuan Formation. The sand body type of the Carboniferous-Permian favorable reservoir in the Huangyan depression is the fluvial facies sand body and the delta facies sand body. Based on the study of the Upper Paleozoic sandstone reservoir in the Upper Paleozoic, the upper Paleozoic reservoir is mainly composed of the feldspar sandstone and the lithic feldspar sandstone, but the vertical difference is obvious. The generalized quartz sandstone (including the rock-rock and the long-stony quartz sandstone) is mainly distributed in the lower-stone box group and the upper-stone box group, and the quartz content in the reservoir shows a significant increase from the bottom to the bottom, and the content of the rock fragments shows a tendency to lower from the bottom to the bottom. The maturity of the sandstone and the maturity of the structure are gradually decreasing. In the whole, the relatively good layer segment of the inner hole of the reservoir is the lower stone box group of the channel sand body and the key area for further exploration. The second is Taiyuan Formation, the upper stone box group is relatively poor. On the basis of data, the formation of Shanxi Formation shows very poor permeability and belongs to the non-permeable layer. The influence of diagenesis on the reservoir physical property of the study area is very obvious, and in many factors which restrict the reservoir physical property, the compaction effect basically determines the reservoir property of the sandstone, and the compaction effect plays a negative role in the reservoir physical property modification process. Resulting in a large amount of pore loss in the reservoir. In the middle and late stage of the burial depth of the sand body, the effect of the cementation gradually replaces the compaction, which is the main force to destroy the reservoir performance of the sand body, and the clay-rock cement, the carbonate cement and the siliceous cement are the main reasons for reducing the porosity and the permeability of the sandstone reservoir. The dissolution (acid corrosion and alkaline corrosion) has produced a large number of secondary pores, which greatly improves the reservoir physical property and plays an active role in the formation of the reservoir space of the oil and gas. The reservoir space of the Upper Palaeozoic Sandstone in the Huangyan depression is formed in the whole, and the remaining sections are not found in the primary pores, and the secondary-particle-soluble, intragranular and mold-shaped pores are the main ones, and only the fractures in the Shanxi Formation are relatively developed. The formation of secondary pores greatly improves reservoir physical properties. As a whole, the drainage pressure of the upper stone box group is small, the separation coefficient of the throat is small, and the connectivity of the well throat is good; the lower stone box and the Taiyuan group have the middle discharge pressure, the separation coefficient is small, the connectivity of the pore throat is lower than the upper stone box group, and the discharge pressure of the Shanxi group is the most, The separation coefficient is the highest, and the pore-throat connectivity is the worst. The upper Paleozoic reservoir in the Huangbu depression is mainly characterized by the characteristics of ultra-low porosity, low porosity and ultra-low permeability. The reservoir properties of the reservoir are influenced by many factors, and the sedimentary environment and the sedimentary facies determine the original condition of the sandstone reservoir, and the diagenesis has become the main control factor of the reservoir physical property in the post-sedimentary study area. The most favorable reservoir sand body in the Huangyan depression is the river facies sand body of the lower stone box group and the upper stone box group, and the reservoir physical property is good, which is the most promising reservoir in the upper Paleozoic in the area.
