【摘要】：通過(guò)巖心觀察、薄片鑒定及物性測(cè)試等手段,認(rèn)為高磨地區(qū)龍王廟組總體為低孔低滲型儲(chǔ)層,局部為低孔高滲型儲(chǔ)層。儲(chǔ)集巖以砂屑云巖、鮞粒云巖、粉-細(xì)晶云巖和花斑狀粉晶云巖為主。儲(chǔ)集空間包括粒間溶孔、晶間(溶)孔、粒內(nèi)溶孔及鑄�？住堄嗔ｉg孔、膏�？住⑷芏春土芽p。儲(chǔ)層類型分為密集順層溶洞型晶粒云巖儲(chǔ)層(Ⅰ-1類)、溶洞型顆粒云巖儲(chǔ)層(Ⅰ-2類)、針孔和孤立小洞型顆粒云巖儲(chǔ)層(Ⅱ-1類)、針孔型晶粒云巖儲(chǔ)層(Ⅱ-2類)、溶孔和零星小洞型"花斑狀"晶粒云巖儲(chǔ)層(Ⅲ類)(儲(chǔ)層物性依次變差)。巖性、沉積微相、白云化作用和溶蝕作用是影響龍王廟組儲(chǔ)層發(fā)育的關(guān)鍵因素。灘核的砂屑云巖及云坪的粉晶云巖最有利于儲(chǔ)層發(fā)育。第一期準(zhǔn)同生白云化作用利于孔隙的保存。準(zhǔn)同生期溶蝕作用和表生期巖溶作用是龍王廟組產(chǎn)生大量溶孔溶洞的關(guān)鍵因素。埋藏巖溶作用進(jìn)一步改善儲(chǔ)集性能。
[Abstract]:By means of core observation, thin slice identification and physical property test, it is considered that the Longwangmiao formation in Gaomo area is a low porosity and low permeability reservoir, while the local reservoir is a low porosity and high permeability reservoir. The reservoir rock is composed of sand-chip dolomite and oolitic dolomite. The reservoir space consists of intergranular dissolved pore, intergranular (dissolved) pore, intragranular dissolved pore and mold pore, residual intergranular pore and gypsum pore. The reservoir types can be divided into two types: dense reservoir (type 鈪，
