【摘要】：斜溝岔油區(qū)是瓦窯堡油田近幾年才開(kāi)發(fā)的新區(qū)塊。目前仍然處于勘探開(kāi)發(fā)初期階段，，對(duì)油藏的分布認(rèn)識(shí)不清,對(duì)區(qū)內(nèi)沉積、構(gòu)造、儲(chǔ)層特征以及油藏特征沒(méi)有明確的認(rèn)識(shí)。隨著勘探開(kāi)發(fā)進(jìn)程的不斷推進(jìn),有必要對(duì)研究區(qū)油藏進(jìn)行精細(xì)描述,對(duì)有利區(qū)塊進(jìn)行預(yù)測(cè)與評(píng)價(jià)。本文利用研究區(qū)大量地質(zhì)、巖心、鉆井、錄井和地球物理測(cè)井等資料,用切合研究區(qū)實(shí)際的方法和技術(shù),對(duì)研究區(qū)延長(zhǎng)組地層、構(gòu)造、沉積、儲(chǔ)層特征、油藏特征等進(jìn)行了研究和評(píng)價(jià)。發(fā)現(xiàn)本區(qū)油藏發(fā)育整體較差,開(kāi)發(fā)層系主要為長(zhǎng)2、長(zhǎng)4+5、長(zhǎng)6油層組,以平緩的西傾單斜為主,局部發(fā)育鼻狀隆起,油藏具有低孔、低滲、低含油飽和度的特點(diǎn),屬于地質(zhì)構(gòu)造活動(dòng)較弱的巖性油藏。主要的有效烴源層是長(zhǎng)7層的張家灘頁(yè)巖及暗色泥巖。油氣的運(yùn)移方式以垂向和近距離側(cè)向運(yùn)移為主。油藏分布與構(gòu)造關(guān)系非常密切,長(zhǎng)6、長(zhǎng)4+5油藏主要分布在鼻隆及坡度較陡的地區(qū),長(zhǎng)2油藏分布在構(gòu)造的高部位。最終對(duì)有利含油區(qū)塊進(jìn)行預(yù)測(cè),為整個(gè)區(qū)塊后續(xù)的開(kāi)發(fā)提供了地質(zhì)依據(jù)。
[Abstract]:Jiaogoucha oil area is a new block developed in Wayaobu oilfield in recent years. At present, it is still in the early stage of exploration and development. The distribution of the reservoir is not clear, and there is no clear understanding of the deposition, structure, reservoir characteristics and reservoir characteristics in the area. With the development of exploration and development, it is necessary to describe the reservoir in the study area and to predict and evaluate the favorable area. In this paper, a large amount of geological, core, drilling, logging and geophysical logging data are used to study the formation, structure, deposition and reservoir characteristics of Yanchang formation in the study area. Reservoir characteristics were studied and evaluated. It is found that the development of reservoirs in this area is poor as a whole. The development layers are mainly Chang 2, Chang 45, Chang 6 oil layers, with gentle westward inclination and monoclinal, local nose uplift. The reservoirs have the characteristics of low porosity, low permeability and low oil saturation, and the reservoir is characterized by low porosity, low permeability and low oil saturation, and the reservoir is characterized by low porosity, low permeability and low oil saturation. It belongs to lithologic reservoir with weak tectonic activity. The main effective source beds are Zhangjiatan shale and dark mudstone. The oil and gas migration mode is mainly vertical and close lateral migration. The reservoir distribution is closely related to the structure. Chang 6 and Chang 45 reservoirs are mainly distributed in the areas with steep slope and nose uplift, and Chang 2 reservoirs are located in the high parts of the structure. Finally, the favorable oil-bearing blocks are predicted, which provides geological basis for the subsequent development of the whole block.
