The result is that this gas pool has simple structure, only forms a little nose - like structure at the district of fenghuangshan ; this pool belongs to delta front sub - facies sedimentary model, the underwater distributary channel and mouth bar is the better sedimentary microfacies ; the physical property of the reservoir is poor, the type of pore of the reservoir rock mostly are intergranular pore, intergranular solution hole and little are intercrystalline micropore ; the influential factors of pore structure and physical property are lithofacies, lithologic character and diagenesis ; the off - take potentia of all the testing well are deadly shortness, the wells have the worth of industrial recovery only under the condition of going through sand fracturing, and in the early of binging into production, the oil and sheath pressure drop rapidly, the production of the well drop rapidly
研究認為該氣藏構造簡單,只在鳳凰山形成了一個小型的鼻狀構造;屬於三角洲前緣亞相沉積模式,水下分流河道和河口壩是有利的沉積微相;儲層物性差,儲層巖石的孔隙類型主要有粒間孔、粒間(內)溶孔及少量晶間微孔;影響蓬萊鎮組氣藏儲層孔隙結構及儲集性的因素有巖相、巖性條件及成巖作用;所有測試井自然產能都極低,必須經加砂壓裂后才有工業開采價值,且投產初期,油套壓下降較快,氣井產量下降迅速。The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明,該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖;儲層巖石經歷了壓實,膠結,溶蝕等成巖作用,歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期( b亞期)膠結充填孔隙縮小期三個成巖-孔隙演化階段;儲層物性總體上具有較低孔滲、低孔滲的特點,孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔,裂縫不發育,儲集巖排驅壓力和中值壓力較高,孔隙結構類型以細小孔-微孔隙,微細喉-微喉型為主。The favorable reservoir spaces in the carbonate rock could be divided into five types according to their origin, configuration and size, i. e., solution fissure, solution hole, cave, erosional fissure and structural fissure, which form five different reservoirs including cave - type reservoir, erosional fracture reservoir, structural fissure reservoir, and solution pore marginal beach grainstone reservoir
而下奧陶統灰巖段儲集和生產油氣的有效儲滲空間按成因、形態及大小可劃分為溶蝕孔隙、溶蝕孔洞、大型洞穴、風化裂隙、構造裂隙等5類,構成5種性質有別的儲層,即洞穴型儲層、風化裂隙型儲層、構造裂隙型儲層、臺緣灘相顆粒灰巖溶蝕孔隙型儲層和地表殘積物裂隙孔隙(洞)型儲層。This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎,控制了儲集砂體的形態特徵和分佈范圍,同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同,從而也影響著砂巖所經歷的成巖作用路徑、類型和強度,因此沉積作用是控制儲層發育的主導因素;成巖作用是關鍵,直接決定了砂巖的孔隙演化過程,從而決定了儲層內部儲集空間特徵和儲集性能;而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。It is proved by the result of oil test that the combination of such three parameters as the density of fissures, porosity data and permeability data can be used to evaluate the quality of reservoirs in huang - yu - re area more exactly, among which the density of fissures is the leading reference for the evaluation
實際試油結果表明裂縫密度孔隙度滲透率3個參數結合能夠較好地反映該區儲層的好壞,其中裂縫密度是評價儲層質量的主要依據。裂縫改善了火山巖的儲集性能,斷裂活動控制著儲層中裂縫的發育。分享友人
