【摘要】：十屋油田位于梨樹(shù)斷陷北部，其豐富的油氣物質(zhì)基礎(chǔ)和眾多的沉積體系構(gòu)成的多樣化的復(fù)合圈閉，使其具有良好的找油氣前景。十屋油田以往的勘探開(kāi)發(fā)工作主要分布在中淺層，隨著勘探程度的加深，深部層位越來(lái)越受到重視。但在實(shí)際工作過(guò)程中，該區(qū)的油氣潛力一直未得到最大的發(fā)掘。營(yíng)城組作為梨樹(shù)斷陷深部良好的儲(chǔ)蓋層組合，更是得到廣大學(xué)者的關(guān)注。 本文應(yīng)用偏光顯微鏡、掃描電鏡、鑄體薄片分析和X-射線衍射等技術(shù)方法和手段，結(jié)合砂巖物性特征數(shù)據(jù)，對(duì)營(yíng)城組砂巖進(jìn)行系統(tǒng)的巖石學(xué)研究、成巖作用研究和儲(chǔ)層物性特征研究，并分析了影響砂巖物性特征的因素。 十屋油田營(yíng)城組四個(gè)砂組（K1yc1、K1yc2、K1yc3、K1yc4）發(fā)育的砂巖主要為巖屑長(zhǎng)石砂巖和長(zhǎng)石巖屑砂巖，還有少量的長(zhǎng)石砂巖、巖屑砂巖和火山凝灰?guī)r。碎屑物均以石英、長(zhǎng)石和火山巖屑為主，填隙物普遍含量相對(duì)較少，膠結(jié)物以鈣質(zhì)膠結(jié)物和硅質(zhì)膠結(jié)物為主。 營(yíng)城組砂巖經(jīng)歷了復(fù)雜的成巖作用改造，其中機(jī)械壓實(shí)作用和壓溶作用表現(xiàn)明顯，造成顆粒緊密堆積，，致使粒間孔不發(fā)育；膠結(jié)作用強(qiáng)烈，膠結(jié)物類型多，膠結(jié)期次復(fù)雜，嚴(yán)重影響儲(chǔ)層的孔隙特征；溶解作用主要發(fā)生在長(zhǎng)石和巖屑顆粒的邊緣和內(nèi)部，形成了次生孔隙，對(duì)儲(chǔ)層物性有著積極的改造作用；蝕變作用主要發(fā)生在長(zhǎng)石和巖屑中，但是蝕變程度普遍偏低。在經(jīng)歷了復(fù)雜的成巖作用之后，營(yíng)城組砂巖成巖階段達(dá)到了中成巖階段A-B期。 營(yíng)城組四個(gè)砂組儲(chǔ)層砂巖發(fā)育的孔隙類型主要有擴(kuò)大粒間孔、粒內(nèi)溶孔和鑄�？祝簧皫r面孔率偏低，多數(shù)屬低級(jí)別，孔隙直徑相對(duì)較小，大部分屬于小級(jí)別孔徑，喉道寬度多屬中喉級(jí)別，起到了很好的連通作用。儲(chǔ)層類型主要為低孔-特低孔—特低滲-中滲型儲(chǔ)層，中央構(gòu)造帶小五家子以北SN17-SN203-SN201-SN165-SW103-SW6一帶為有利區(qū)塊。 成巖作用中的機(jī)械壓實(shí)作用、溶解作用和交代蝕變作用，對(duì)砂巖的儲(chǔ)層物性特征有著重要的影響。淺部受機(jī)械壓實(shí)作用影響明顯，表現(xiàn)為隨深度的增加，孔隙度和滲透率降低；深部受溶解作用影響，形成次生孔隙，使孔隙度和滲透率有所提高。
[Abstract]:Shiwu Oilfield is located in the northern part of Lishu fault depression. Its rich oil and gas material foundation and multiple sedimentary systems make it have a good prospect for oil and gas exploration. The exploration and development work in Shiwu Oilfield was mainly distributed in the middle and shallow strata in the past. With the deepening of exploration degree, more and more attention has been paid to the deep layer. However, the oil and gas potential in this area has not been maximized in the actual working process. Yingcheng formation, as a good reservoir and caprock assemblage in the deep part of Lish fault depression, has been paid more attention by many scholars. In this paper, a systematic petrological study of the Yingcheng formation sandstone is carried out by means of polarizing microscope, scanning electron microscope, thin slice analysis of cast body and X-ray diffraction, combined with the physical property data of sandstone. Diagenesis and reservoir physical characteristics are studied, and the factors affecting sandstone physical characteristics are analyzed. The sandstones developed in the four sand formations of Yingcheng formation, Shiwu Oilfield are mainly lithic feldspathic sandstone and feldspathic sandstone, as well as a small amount of feldspathic sandstone, lithic sandstone and volcanic tuff. The clastic materials are mainly quartz feldspar and volcanic debris and the content of interstitial matter is relatively small and the cementation is mainly composed of calcareous cement and siliceous cementation. The sandstone of Yingcheng formation has undergone complex diagenesis transformation, in which mechanical compaction and pressure dissolution are obvious, resulting in tight accumulation of particles, resulting in undeveloped intergranular pores, strong cementation, many types of cementation, and complex cementation period. The dissolution occurs mainly in the edge and interior of feldspar and lithic grains, forming secondary pores, which have a positive effect on reservoir physical properties, and alteration occurs mainly in feldspar and lithic debris. However, the degree of alteration is generally low. After complicated diagenesis, the diagenetic stage of Yingcheng formation reached A-B stage. The pore types of sandstone in the four sand formation reservoirs of Yingcheng formation are mainly expanded intergranular pore, intragranular dissolved pore and mold pore, and the sandstone porosity is low, most of them belong to low grade, the pore diameter is relatively small, and most of them belong to small pore size. The width of laryngeal tract belongs to the level of middle larynx, which plays a good role in connecting. The reservoir types are mainly low porosity, very low permeability and medium permeability reservoirs, and favorable blocks are located in the SN17-SN203-SN201-SN165-SW103-SW6 area north of Xiaowujiazi in the central structural belt. The mechanical compaction dissolution and metasomatism in diagenesis play an important role in the reservoir physical properties of sandstone. The shallow part is obviously affected by mechanical compaction, which shows that the porosity and permeability decrease with the increase of depth, and the deep part is affected by dissolution, forming secondary porosity, which increases porosity and permeability.
